Human Brain Protein Associated with Autism

A mutant gene that encodes a brain protein in a child with autism has been placed into the brains of fruit flies. Fruit flies hosting that gene produce the variant human brain protein and show abnormal behaviors of fear, repetitive activity and altered social interaction, reminiscent of autism impairments.

The genetic variant was found in the Simon Simplex Collection, which has collected genetic samples from 2,600 simplex families with autism spectrum disorder, or ASD. The brain protein is the dopamine transporter, or DAT, whose job is to pump the neurotransmitter dopamine back into nerve cells once the neurotransmitter has been released. The mutant protein is missing a single amino acid.

A study of this variant DAT — from its impaired molecular mechanism to its effect on fruit fly behavior — has been published in Proceedings of the National Academy of Sciences by co-corresponding authors Aurelio Galli, Ph.D., and Eric Gouaux, Ph.D.

Galli is professor in the Department of Surgery at the University of Alabama at Birmingham, and Gouaux is professor in the Vollum Institute at the Oregon Health & Science University and Howard Hughes Medical Institute.

Researchers found that fruit flies with the human variant DAT, or vDAT, are hyperactive. They had increased locomotor activity in both day and night, as compared with normal fruit flies. They also showed repetitive behavior — the vDAT fruit flies groomed themselves 23 percent of the time, versus 6 percent of the time for normal fruit flies. Repetitive behavior like self-grooming has been observed in animal models of neuropsychiatric disorders.

The vDAT fruit flies were also more fearful than normal fruit flies. In response to the sound of a predatory wasp, normal flies froze for about 150 milliseconds, and then they fled, as shown by a distinctive and rapid increase in average velocity that was captured by a 1,000-frame per second camera. In contrast, the vDAT fruit flies froze at the sound of the predator and showed little signs of fleeing during 600 milliseconds.

The vDAT fruit flies had impaired social interaction, as measured by changes in grouping. Many animal populations form temporary or permanent groups, such as flocks, schools or herds, that aid survival in the face of predators. Fleeing, in response to a threat, is an escape behavior where the flock size may compress or expand. The researchers found that normal fruit flies expanded their flock size in response to a threat — the sound of the predator wasp. The vDAT fruit flies, in contrast, compressed their flock size.

Besides the fruit fly behavior, the PNAS study is a comprehensive multidisciplinary approach that gets at some root causes of autism to a degree of detail that could make potential therapeutic treatments more realizable in the future.

Besides vDAT, the labs of Galli and Heinrich Matthies, Ph.D., assistant professor in the UAB Department of Surgery, have identified several other mutations in the human DAT gene that affect DAT function in individuals with ASD. For these people, disruption of dopamine transport appears to be a risk factor that promotes complications associated with ASD.

“The experimental paradigms we describe here,” Galli said, “provide a framework for molecular and behavioral analysis of novel DAT variants that are discovered by genetic analyses of individuals with ASD or related neuropsychiatric illness, as well as other disease-linked mutants that are emerging from precision medicine initiatives.”

Galli and Gouaux’s PNAS research went from human genetics to a basic animal model with simplified behavior, as detected by a new high-powered analysis. It investigated the underlying molecular mechanisms and basic biological functions with ever greater resolution, through studies at the cell level and all the way down to a bacterial system. Each added system was more fundamental with regard to biological complexity and phylogenetic level.

Details of vDAT structure and function
Besides altered fly behavior caused by the mutant protein, the PNAS study probed the molecular structure and function of vDAT using mutation of a related transporter protein from a thermophilic bacterium as a model. Experiments included X-ray crystallography, spin resonance spectroscopy, molecular modeling, cell culture studies and electrophysiology studies of fruit fly brains expressing the mutant.

The researchers showed that vDAT cells have impaired dopamine transport and impaired DAT-mediated electrical currents. Also, expression of the human vDAT reduced dopamine uptake in the whole brain of fruit flies. These findings support the idea that human DAT dysfunction in ASD stems from specific and yet distinct mechanisms.

To probe the mechanism of impaired transporter function, researchers used the related bacterial transporter as a model. They removed the single amino acid from the related bacterial transporter that correlates with the single amino acid missing in vDAT. Like DAT, the bacterial transporter protein embeds across the cell membrane and has domains called the extracellular gate and the intracellular gate to receive and release the molecule being transported from outside the cell to inside.

Advertisements

Deletion of the single amino acid altered conformation of the bacterial protein and appeared to lock its extracellular gate, apparently through disrupted hydrogen bonds between amino acids of the protein that abnormally left the intracellular gate in a conformation called “half-open and inward facing.” Molecular dynamics simulation of vDAT showed similar conformational changes and altered hydrogen bonding.

Children’s of Alabama Expands Sensory Pathway For Patients With Sensory Sensitivities

Advertisements

When Sladen Fisher got a bad cut on his earlobe at school, his mother, Jennifer Fisher, worried the sights and sounds of Children’s of Alabama’s Emergency Department would be too stressful for her son. That’s because Sladen has attention deficit hyperactivity disorder (ADHD) and sensory processing disorder.

At the time of the Sladen’s visit, Children’s of Alabama had just launched its Sensory Pathway, designed for patients with conditions such as ADHD, autism and Down syndrome. In 2016, the pathway began as a pilot project in the Emergency Department; however, it has since expanded to One Day Surgery and several inpatient units at Children’s of Alabama, including the Pediatric Intensive Care Unit, Pulmonary Care Unit and Special Care Unit. Future plans include expansion to ancillary and outpatient services.

The pathway made a lasting impact on Sladen. Back at school a few weeks later, he presented a report about someone he considers a hero. He chose Children’s of Alabama Child Life Specialist Shelby Smith, who stayed by his side during his visit, explained his treatment in terms he understood and provided him with an iPad and fidget toys for distraction and comfort.

“In his mind, she was a hero, someone who went above and beyond to help him,” Jennifer said. She made what could have been an incredibly difficult situation so amazing. She really was our hero.”The pathway has been equally impactful on Children’s of Alabama, said Michele Kong, M.D. associate professor in pediatric critical care at the University of Alabama at Birmingham (UAB) Department of Pediatrics.

Advertisements

“The pathway has been so empowering for our providers,” said Kong, who serves on the Sensory Pathway Task Force, also comprised of nurses, informatics specialists and child life specialists. Unit by unit, the task force provides education and training and is developing an online training module. The task force is also working with information technology specialists to flag patients with sensory sensitivities from the point of admission.

“We tailor education and training to suit each unit’s needs because each unit’s workflow and culture is different,” Kong said. “The success of the pathway is a direct reflection of our providers’ passion to learn. There’s buy-in from our providers because they know it’s good for their patients.”

As a parent, Kong, too, knows how jarring a hospital visit can be for a child with sensory sensitivities. Her oldest son, Abram, was diagnosed with autism at age 4. The diagnosis inspired Kong and her husband, Julian Maha, M.D., to found KultureCity®, a nonprofit that works to “create acceptance and inclusion for all individuals with unique abilities,” according to its mission statement. In 2019, KultureCity was ranked fourth on Fast Company magazine’s list of the most innovative companies in the world. KultureCity not only partners with local organizations in Birmingham, but also with national organizations such as the NBA and NFL.

“We never imagined it would reach this scale,” Kong said. “It impressed on us that there’s a lot of power when a collective group of people have the same belief and passion for change.”

'Financial infidelity'

What defines it, who is at risk, and what are the consequences?

Advertisements

Romantic partners aren’t always honest about money in their relationships, but when does hiding purchases, debt and savings constitute “financial infidelity”? Research by professors at four universities, including Indiana University, defines the concept and provides a means for predicting its occurrence within relationships.

Advertisements

Love, Lies and Money: Financial Infidelity in Romantic Relationships,” in the Journal of Consumer Research, is the first systematic investigation of financial infidelity in committed romantic relationships.

The professors define financial infidelity as “engaging in any financial behavior that is expected to be disapproved of by one’s romantic partner and intentionally failing to disclose this behavior to them.” It involves both the financial “act” and the subsequent concealment.

It differs from secret consumption and merely hiding spending because it involves a broader set of financial behaviors, including seemingly “positive” actions such as saving extra income in a personal bank account.

Advertisements

“Financial infidelity has the potential to be as harmful for relationship health and longevity as sexual infidelity, as conflicts over money are also a primary reason for divorce,” said co-author Jenny Olson, assistant professor of marketing at the IU Kelley School of Business. “Given the role that finances play in the health of relationships, consumers benefit from being aware of financial infidelity and its consequences.”

Growing in popularity is financial therapy, which combines finance with emotional support to help individuals and couples think, feel and behave with money to improve their overall well-being, make logical spending decisions and face financial challenges.

Advertisements

“An understanding of financial infidelity can benefit financial services companies and advisors, clinical therapists and relationship counselors, all of whom play a role in promoting consumer well-being,” Olson said. “If couples seek professional financial advice, they must be willing to openly discuss their spending and savings habits, debts and financial goals. It is clear that financial infidelity is a barrier to effective planning, as well as to a healthy relationship.”

The researchers developed a “financial infidelity scale (FI-Scale)” using a dozen lab and field tests. Key findings included:

  • Whether the financial act is expected to elicit any level of disapproval was more important than the degree of disapproval.
  • Consumers more prone to financial infidelity exhibited a stronger preference for secretive purchase options, such as using a personal credit card versus a jointly held card, and cash over credit.
  • A preference for ambiguous packaging and shopping at inconspicuous stores.
  • A greater likelihood of concealing financial information from their partner in a mobile banking app.

Each choice is relevant to marketers. The prevalence of financial infidelity among consumers and variations along the FI-Scale affect purchasing decisions. It is important that companies be aware of certain consumer segments that may be prone to financial infidelity and thus affect their bottom lines.

For example, the trend of businesses going “cash-free” may affect retailers such as beauty salons and gift shops because of the use of cash to disguise purchases. Consumers strategically using cash may be less willing to make purchases only for their pleasure or personal wants.

Early Intervention in Autism Improves Language, IQ and Social Skills

Sally Rogers, PhD works with a child.

Breakthrough research demonstrating that children with autism as young as 18 months can vastly improve their language, cognition and social skills with an early intervention developed by UC Davis Professor Sally Rogers has been replicated in a major new study.

Advertisements

Rogers, a professor of Psychiatry and Behavioral Sciences at the MIND Institute, began work on a novel developmental approach to autism in Denver in 1981, and in partnership with her colleague and co-author Geraldine Dawson developed an approach to improving long-term outcomes for very young children. The Early Start Denver Model has since become a method used throughout the U.S. and around the world.

But until now ESDM had not been tested in the most rigorous fashion − a multi-site randomized trial, comparing the approach with community-based autism interventions. The study, which appears today in Journal of the American Academy of Child and Adolescent Psychiatry, began in 2007 at three university sites around the country. The new research replicates an ESDM study published in 2010. Rogers emphasized that replication studies are rare and costly but critical to validate novel scientific findings.

The new study found that children receiving intensive ESDM in their homes for an average of 15 hours per week made significantly greater language gains than did children in the community interventions, and this was true for both children with more severe delays and those with less.

Advertisements

In addition to validating the efficacy of ESDM for language development, the study also found that children receiving services in the community settings made large gains in several areas.

“The idea that little children with autism who are getting good treatment can make this much IQ and language gain means we should expect this from quality early-intervention experiences,” Rogers said. “These findings should raise families’ hopes a whole lot.”

Advertisements

Pioneering autism treatment was a new idea

What distinguishes ESDM from the more traditional, behavioral interventions used with children with autism is that it combines developmental and behavioral approaches and is carried out within in everyday routines. ESDM is built on moment-to-moment interactions that young children typically have with other people, especially their parents, and uses children’s interests and favorite activities to assure that social interaction is interesting and fun.

Advertisements

“Unlike other approaches popular at the time that the Denver Model began, we used a typical preschool physical environment and focused on the learning opportunities that existed in social interactions between children and adults to accelerate children’s development,” Rogers said. “This was a new idea at the time.”

In 2012, TIME magazine named ESDM one of the top 10 medical breakthroughs because their work demonstrated that brain function among young children with autism can normalize with effective early intervention in profound, enduring ways.

For the current study 118 children with autism, ages 14 months to two years, were enrolled and randomly assigned to either ESDM or community interventions for 27 months. Children assigned to ESDM intervention received three months of weekly parent coaching followed by 24 months of one-on-one treatment about 15 hours per week in homes or daycare settings from supervised therapy assistants. Parents received coaching four hours monthly from a certified ESDM therapist. In the community setting, hours of treatment varied by site.

What researchers found was that at two of the three sites, children receiving ESDM had significantly more language improvement than the children in the community interventions, and there was no significant difference in language gain at the third site between the two modalities. When results from all three sites were pooled, there was a significant advantage for the children in the ESDM group overall.

“Language is the bridge to learning,” Rogers said. “Language is the door that opens up social communication and education and interactions with people in your community. It’s how you share with people. It’s a main vehicle for social interaction once you pass infancy.”

Autism treatment in the community greatly improved over time

 The study also found that in terms of cognition and social skills, both the ESDM and community treatment groups made significant gains. Fortunately, Rogers said, laws requiring insurance coverage for early autism intervention and new knowledge about effective treatment have greatly improved community options for families seeking help for young children diagnosed with autism.

Rogers said families with a child diagnosed with autism should take some comfort knowing that the early treatments now widely available do make a difference.

“It says the autism scores at the time of diagnosis are just a starting point,” she said. “It says that the developmental paths and learning capacity of young children with autism are more plastic than we knew, and there are many ways to get learning opportunities to them.”

In addition to Rogers, UC Davis authors on the study were Marie Rocha, Laurie Vismara and Meagan Talbott. Other co-authors on the study included: Annette Estes and Jessica Greenson of the University of Washington; Catherine Lord and Jamie Winter of Weill Cornell Medicine, Cornell University; Costanza Colombi of University of Michigan; Geraldine Dawson of Duke University, and Gerhard Hellemann of UCLA.

This study was supported by individual Autism Speaks grants to Annette Estes and to Sally Rogers and by NIMH/NICHD award number R01 081757 as part of the Autism Centers of Excellence (ACE) Treatment Network, clinicaltrials.gov identifier NCT 00698997.

Supporting Individuals With Autism in the Workplace

Advertisements

In recent days there has been significant coverage surrounding the Boca Raton native becoming the first openly autistic person to be admitted to the Florida bar. This accomplishment being widely accepted is a huge stride for those diagnosed with autism and autism professionals working hard to create inclusive workplaces.

Advertisements

To help others understand why inclusivity and supporting those with disorders is so important, I’d like to offer Arianna Esposito, Associate Director of Adult & Transition Programs at the Kinney Center for Autism Education and Support at Saint Joseph’s University. She is able to offer tips to help employers create an inclusive workplace. These tips are not only helpful for individuals with autism, but can benefit all employees. Please see a sampling of her advice below:

Advertisements
  • Sensory-Friendly Environment
Advertisements

Fluorescent lights can be extremely bothersome for someone with sensory challenges. Offering dimmer lighting options or access to natural light are good alternatives. Odorless office supplies, cleaning supplies and other products are recommended to have in a supply closet or open areas. Designated, private quiet rooms for employees to take a call in or do work are a great option.

Advertisements
  • Open communication

Providing clear and specific feedback is important for an inclusive structure. Try putting a positive spin on code of conduct by turning “do not” rules into “can do” rules.

Advertisements
  • Flexibility

Being flexible with needs such as accepting requests to wear specific clothing items and seating locations (not near crowded areas) will help individuals navigate the social world.

HPV Vaccine: 7 Myths and Facts You Need to Know

Nuvance Health physician dispels common misconceptions about the HPV vaccine and discusses its role in protecting against HPV-related diseases

Summary:

  • A vaccine is available to protect against human papillomavirus (HPV). HPV is the most common sexually transmitted infection and can cause diseases such as genital warts and cancer.
  • The HPV vaccine now protects against nine strains of HPV. Research shows that the HPV vaccine is safe and effective.
  • The HPV vaccine is approved for men and women between the ages of 9 to 45. The HPV vaccine can protect adults from HPV-related diseases, however it provides the most protection when it is given in childhood before someone becomes sexually active.
  • Parents should talk with their child’s pediatrician about the HPV vaccine. Adult men should ask their primary care provider about the HPV vaccine, and adult women should speak with their gynecologist.
Advertisements

In 2006, the U.S. Food and Drug Administration (FDA) approved Gardasil, a vaccine to prevent diseases such as cancer and genital warts that are caused by human papillomavirus (HPV). Within the last five years, improvements have been made to the HPV vaccine and the recommended age range for administration has been expanded, resulting in more robust HPV protection being available to more people.

Although the HPV vaccine has proven to be highly effective at preventing HPV-related diseases and cancers, misconceptions still exist about how it works, who should receive it, and whether it is safe. Here are seven myths about HPV and the HPV vaccine and also the facts you need to know.

Myth #1: I/my child won’t contract HPV.
Fact: HPV is the most common sexually transmitted infection.

Most sexually active people will contract HPV. The U.S. Centers for Disease Control and Prevention (CDC) estimates that nearly 80 million people — or 1 in 4 Americans — are infected with HPV. The CDC further estimates that about 14 million people, including teens, will contract a new HPV infection each year.

Advertisements

Myth #2: Having HPV doesn’t mean I/my child will get cancer.
Fact: Having HPV increases cancer risk — and HPV-related cancers are on the rise.

According to the CDC, more than 43,000 people developed HPV-associated cancer in 2015, up from 30,000 people in 1999. The HPV vaccine can prevent most types of HPV-related cancers, including anal, cervical, penile, throat, and vaginal cancers.

Myth #3: The HPV vaccine is only for women.
Fact: Men and women should get the HPV vaccine.

HPV affects both men and women. HPV can cause genital warts and anal and oral cancers in both men and women. It can also cause cervical or vaginal cancers in women and penile cancers in men. Because HPV often does not cause symptoms right away and many people are unaware that they have it, it can easily and unknowingly be transmitted to a sex partner.

Myth #4: The HPV vaccine isn’t effective.
Fact: The newest vaccine is effective against nine strains of HPV.

When Gardasil, the original HPV vaccine, was first approved by the FDA in 2006, it only protected against four types of HPV. In 2014, the FDA approved a new vaccine called Gardasil 9 that protects against the same four types of HPV, plus an additional five types.

Advertisements

Research also shows that the HPV vaccine provided nearly 100 percent protection against persistent cervical infections with HPV types 16 and 18, plus the pre-cancers caused by those persistent infections.

Myth #5: The HPV vaccine is only for children and young adults.
Fact: Children and adults ages 9 to 45 can now get the HPV vaccine.

Gardasil and Gardasil 9 were originally approved for boys and girls ages 9 to 26. In 2018, the FDA expanded the age range for Gardasil 9 to include men and women ages 27 to 45. This expanded approval provides more opportunity to prevent HPV-related diseases and cancers in a broader age range.

Advertisements

Although the HPV vaccine is most effective when it is given before someone becomes sexually active — ideally in childhood — there is now data that suggests that the vaccine also can benefit adults. Statistics show that many sexually active adults have been exposed to some types of HPV, but most have not been exposed to all nine types covered by the newest vaccine. Even if an adult already has HPV, the vaccine may still help to reduce the risk of developing HPV-related diseases.

Myth #6: The HPV vaccine isn’t safe.
Fact: Extensive testing and research show that the HPV vaccine is safe.

The FDA closely monitors the safety and effectiveness of all vaccines before and after approval, and research shows that the HPV vaccine is safe. However, like any other vaccine or medication, some people may experience mild reactions or side effects to the HPV vaccine, such as fever, dizziness, fatigue, or pain, redness, or swelling at the injection site.

Myth #7: The HPV vaccine encourages sexual promiscuity.
Fact: Research has shown no link between being vaccinated for HPV and an increase in sexual activity.

Advertisements

Recent research that included 500,000 individuals found that there was no increase in sexual activity after HPV vaccination. Additionally, the research showed that participants who received the HPV vaccine actually engaged in safer sexual practices than unvaccinated participants.

The bottom line: The HPV vaccine is a safe and effective way to reduce your risk (or your child’s risk) of developing an HPV-related health problem. Parents should ask their child’s pediatrician about the HPV vaccine — ideally before the child becomes sexually active. Adult men should speak with their primary care provider about the HPV vaccine, and adult women should talk with their gynecologist.

How Healthy is Chicken Noodle Soup?

Advertisements

You may remember a loved one making you a bowl of chicken noodle soup whenever you were feeling under the weather as a child. Just how healthy is this culinary cure-all?

“Studies have shown that a hearty bowl of chicken noodle soup may help clear nasal congestion and ease cold symptoms,” says BIDMC clinical dietitian Sandy Allonen, RD. “It’s all about the ingredients.”

So let’s break it down – what’s in your soup?

Broth

If you’re fighting a cold, your doctor will tell you it’s important to stay hydrated. “A clear broth is warm and soothing, making it a great source of hydration while you’re sick, especially if you have a sore throat,” Allonen says.

Advertisements

Whether it’s vegetable or chicken broth – Allonen says the benefits are similar. “You may think added salt and other seasonings aren’t great for you, but in moderation, these spices can help combat the feeling of dull taste buds,” she says. “A loss of taste is common in a cold, but as with any flavor enhancer, salt is great for getting you to eat more.”

Allonen notes, however, that if your doctor has recommended you limit your sodium intake (whether this be for hypertension, kidney disease, congestive heart failure or another medical condition), then you will want to look for a broth that is low sodium or has no added salt.

Advertisements

Chicken

Chicken is full of protein that helps support the immune system. It’s also a good source of vitamins and minerals, such as B vitamins, which boost immunity and help regulate digestion.

“Chicken is also high in tryptophan, which helps your body produce serotonin that can enhance your mood and give you the feeling of ‘comfort’ that helps make chicken noodle soup a true comfort food,” Allonen says.

Advertisements

Noodles

The noodles in chicken noodle soup aren’t just for show. They’re packed with carbohydrates that help you feel full and satisfied.

“Carbs are the preferred source of energy for your body, so getting in a good dose through soup can help you feel less sluggish,” Allonen says.

Advertisements

Vegetables

All those bits of carrot, celery, and onion commonly found in chicken noodle soup are a great source of vitamins C and K, as well as other antioxidants and minerals. “Not only does this help build a healthy immune system to fight off viruses, it also helps your body recover from illness more quickly,” Allonen says.

Vegetables like carrots are also high in beta-carotene, and can help reduce symptoms due to their anti-inflammatory properties.

Advertisements

Steam

While steam isn’t an ingredient you’ve mixed in, it’s important to serve your soup warm. Hot steam that comes from your cup of soup can be helpful in reducing nasal congestion.

“Steam can open up airways, making it easier to breathe. It also has a mild anti-inflammatory effect that can help relax your muscles and soothe the discomforts of cold symptoms,” Allonen says.

While soup won’t cure your cold completely, it’s a delicious way to load up on nutrients and increase hydration. Make an appointment with your primary care physician if you’re feeling under the weather this winter.

Black Children Tend to be Diagnosed with Autism Later than White Children

The rate of diagnosis for autism spectrum disorders (ASD) is the same among all racial groups — one in 110, according to current estimates. However, a study by a Florida State University researcher has found that African-American children tend to be diagnosed later than white children, which results in a longer and more intensive intervention. The reasons for later diagnoses include a lack of access to quality, affordable, culturally competent health care, according to Martell Teasley, an associate professor in Florida State’s College of Social Work who has conducted a comprehensive review of researchliterature on autism and African-American children. In addition, the stigmaattached to mental health conditions within the black community contribute to misdiagnoses of autism, and underuse of available treatment services.

“There are no subjective criteria for diagnosing autism. Only brain scans can truly provide appropriate diagnoses, because we are dealing with biological and chemical imbalances in the brain,” Teasley said. “Not every child is going to have access to this kind of medical evaluation, particularly those who are indigent and don’t have health care funding.”

Advertisements

Teasley examined ASD diagnosis and treatment strategies, and their effect on African-American families, in “Autism and the African-American Community,” a paper published in a special issue of the journal Social Work in Public Health (Vol. 26, Issue 4, 2011) that dealt with health-care policy issues in the black community related to the human genome.

Teasley co-wrote the paper with Ruby Gourdine, a professor of social work at Howard University in Washington, D.C., and Tiffany Baffour, an associate professor of social work at Winston-Salem State University in North Carolina. Because of the social stigma, Teasley says that some African-American families might be resistant to accept a diagnosis and treatment. “Less discussion about autism among African-Americans or between African-Americans and health care providers leads to misdiagnoses, a lack of treatment and a lack of services,” Teasley said.

Advertisements

“This will lead to greater challenges for families — more stress and anxiety, and poorer developmental outcomes.” African-Americans also might resist a diagnosis and treatment because of a mistrust of mainstream health care providers over past discrimination. “African-Americans are well versed in going to a doctor who might have biases or discriminatory practices, so they may not readily accept what a doctor says,” Teasley said. In addition, a cultural divide between African-Americans and mainstream health care providers can hinder a timely and correct diagnosis.

Advertisements

“There are not enough health care professionals who understand the cultural norms and attributes of the African-American community,” Teasley said. African-Americans live in all types of settings, but the majority live in urban areas, which have seen a decline in the number of mental-health care agencies since the 1980s. “This lack of accessibility causes a problem for some African-Americans,” Teasley said. Once a child is diagnosed with ASD, Teasley says both the child and the members of his or her family needs to receive appropriate training and counseling. “The children need behavioral counseling so they can develop the skills to live as independently as possible,” he said. “The families need to learn how to work with children who are autistic. “Intervention for any autistic child needs to start around age 3, so we can get the child to begin to learn how to eat right and develop normal, healthy routines, which will result in a better developmental outcome,” Teasley said. “Later intervention will result in a poorer developmental outcome that can have a lasting impact on the child’s and family’s quality of life.”

Ten Signs of Possible Autism-Related Delays in 6- to 12-Month-Old Children

Advertisements

Though autism is often not diagnosed until the age of three, some children begin to show signs of developmental delay before they turn a year old. While not all infants and toddlers with delays will develop autism spectrum disorders (ASD), experts point to early detection of these signs as key to capitalizing on early diagnosis and intervention, which is believed to improve developmental outcomes.

Advertisements

According to Dr. Rebecca Landa, director of the Center for Autism and Related Disorders at the Kennedy Krieger Institute in Baltimore, Md., parents need to be empowered to identify the warning signs of ASD and other communication delays. “We want to encourage parents to become good observers of their children’s development so that they can see the earliest indicators of delays in a baby’s communication, social and motor skills,” says Dr. Landa, who also cautions that some children who develop ASD don’t show signs until after the second birthday or regress after appearing to develop typically.

Advertisements

For the past decade, Dr. Landa has followed infant siblings of children with autism to identify red flags of the disorder in their earliest form. Her research has shown that diagnosis is possible in some children as young as 14 months and sparked the development of early intervention models that have been shown to improve outcomes for toddlers showing signs of ASD as young as one and two years old. Dr. Landa recommends that as parents play with their infant (6 – 12 months), they look for the following signs that have been linked to later diagnosis of ASD or other communication disorders: 1. Rarely smiles when approached by caregivers2. Rarely tries to imitate sounds and movements others make, such as smiling and laughing, during simple social exchanges3. Delayed or infrequent babbling4. Does not respond to his or her name with increasing consistency from 6 – 12 months 5. Does not gesture to communicate by 10 months6. Poor eye contact7. Seeks your attention infrequently8. Repeatedly stiffens arms, hands, legs or displays unusual body movements such as rotating the hands on the wrists, uncommon postures or other repetitive behaviors9. Does not reach up toward you when you reach to pick him or her up10. Delays in motor development, including delayed rolling over, pushing up and crawling

Advertisements

“If parents suspect something is wrong with their child’s development, or that their child is losing skills, they should talk to their pediatrician or another developmental expert,” says Dr. Landa. “Don’t adopt a ‘wait and see’ perspective. We want to identify delays early in development so that intervention can begin when children’s brains are more malleable and still developing their circuitry.”

About the Kennedy Krieger Institute Internationally recognized for improving the lives of children and adolescents with disorders and injuries of the brain and spinal cord, the Kennedy Krieger Institute in Baltimore, MD serves more than 16,000 individuals each year through inpatient and outpatient clinics, home and community services and school-based programs. Kennedy Krieger provides a wide range of services for children with developmental concerns mild to severe, and is home to a team of investigators who are contributing to the understanding of how disorders develop while pioneering new interventions and earlier diagnosis.

Sugar changes the chemistry of your brain

Anyone who has desperately searched their kitchen cabinets for a piece of forgotten chocolate knows that the desire for palatable food can be hard to control. But is it really addiction?

The idea of food addiction is a very controversial topic among scientists. Researchers from Aarhus University have delved into this topic and examined what happens in the brains of pigs when they drink sugar water. The conclusion is clear: sugar influences brain reward circuitry in ways similar to those observed when addictive drugs are consumed. The results have just been published in the journal Scientific Reports.

“There is no doubt that sugar has several physiological effects, and there are many reasons why it is not healthy. But I have been in doubt of the effects sugar has on our brain and behaviour, I had hoped to be able to kill a myth. ” says Michael Winterdahl, Associate Professor at the Department of Clinical Medicine at Aarhus University and one of the main authors of the work.

The publication is based on experiments done using seven pigs receiving two liters of sugar water daily over a 12-day period. To map the consequences of the sugar intake, the researchers imaged the brains of the pigs at the beginning of the experiment, after the first day, and after the 12th day of sugar.

“After just 12 days of sugar intake, we could see major changes in the brain’s dopamine and opioid systems. In fact, the opioid system, which is that part of the brain’s chemistry that is associated with well-being and pleasure, was already activated after the very first intake,” says Winterdahl.

When we experience something meaningful, the brain rewards us with a sense of enjoyment, happiness and well-being. It can happen as a result of natural stimuli, such as sex or socializing, or from learning something new. Both “natural” and “artificial” stimuli, like drugs, activate the brain’s reward system, where neurotransmitters like dopamine and opioids are released, Winterdahl explains.

We chase the rush

“If sugar can change the brain’s reward system after only twelve days, as we saw in the case of the pigs, you can imagine that natural stimuli such as learning or social interaction are pushed into the background and replaced by sugar and/or other ‘artificial’ stimuli. We’re all looking for the rush from dopamine, and if something gives us a better or bigger kick, then that’s what we choose” explains the researcher.

When examining whether a substance like sugar is addictive, one typically studies the effects on the rodent brain. ¨It would, of course, be ideal if the studies could be done in humans themselves, but humans are hard to control and dopamine levels can be modulated by a number of different factors. They are influenced by what we eat, whether we play games on our phones or if we enter a new romantic relationship in the middle of the trial, with potential for great variation in the data. The pig is a good alternative because its brain is more complex than a rodent and gyrated like human and large enough for imaging deep brain structures using human brain scanners. The current study in minipigs introduced a well-controlled set-up with the only variable being the absence or presence of sugar in the diet.
