AUTISM and EPILEPSY: what is the link between the 2 diseases?

Epilepsy and autism spectrum disorders, or ASD, present a remarkable degree of comorbidity and may share similar pathological mechanisms. But how are epilepsy and autism related? Does autism cause an increase in epilepsy? Or does epilepsy alter the brain circuit, which then promotes the development of autism? Scientists at the University of California, Riverside, and Rutgers University (New Jersey) are providing the first answers to these questions, with this study conducted in animals.

“One hypothesis is that during brain development inhibitory neurons, which regulate brain rhythms, develop abnormally, the way in which the brain circuit sets in is then abnormal, which can lead to both autism and epilepsy, ”suggests lead author Dr. Viji Santhakumar, associate professor of molecular, cellular and systems biology at the University of California at Riverside.

The key role of inhibitory neurons

The researchers focused on the function of inhibitory neurons in mice. These inhibitory neurons function as a brake by suppressing and regulating the activity of downstream neurons. The researchers generated mice with an overall mutation in all cells that prevents inhibitory neurons from migrating to their normal location in mature brain circuitry. The researchers find:

  • unsurprisingly, a reduction in inhibitory currents in the hippocampus, which plays a key role in memory;
  • these mice experience a high incidence of behavioral traits associated with ASD and seizures;
  • fewer inhibitory neurons in brain circuits seem to induce an abnormality in the development of inhibitory neural circuits.

In summary, the study suggests that a common underlying defect in the formation of inhibitory circuits could contribute to both ASD and epilepsy and provide a basis for further research. The objective would therefore be to identify the mutations underlying the abnormalities of inhibitory neuronal migration and the maintenance of neuronal connections, in the development of ASDs and epilepsy.

What AI tells us about communicating with children

How many interactions do you have with the pupils in your care throughout the day? A seminal study estimated that the number of words, nods, smiles and other gestures that teachers typically use to communicate with their students in any given hour in a mainstream classroom is in the range of 200 to 300 (Jackson, 1969). Research shows that the way teachers communicate with their pupils makes a huge difference to how well they learn (Stronge, 2011). We know that this is even more important for children who are neurodiverse. But which communication techniques work the best? Our research , published this September, helps to answer this question. We used artificial intelligence to identify effective communication strategies for children with autism. It might sound complicated, but it wasn’t really: we recorded interactions between teachers and autistic students in the classroom, and then used AI to identify which teacher communications worked and which did not. More: We spent 20 half-days in a special school in London that had criteria of autism spectrum condition for admission. There, we observed which strategies three teachers used to communicate with seven children – words, visual images, objects, gestures or physical prompts – and we […]

Reversing mutations in top autism-linked gene makes adult mice more social

Treatments that counteract the effects of a mutation in a top autism-linked gene in mice increase the animals’ sociability in adulthood, according to a new unpublished study. Researchers presented the findings virtually at the 2021 Society for Neuroscience annual meeting . The results are based on mice deficient in SCN2A , a gene that codes for an ion channel protein that ferries electrical signals across the brain. Mutations in the gene are strongly linked to autism and often cause epilepsy . Mice missing both copies of SCN2A typically don’t survive long after birth, whereas those that lack only one copy show few behavioral differences from control mice, according to previous work. So to create a useful model for the new study, researchers used a ‘gene trap,’ a snippet of DNA that alters gene expression. Mice engineered with the gene trap express about 25 percent of typical SCN2A levels. The trap also made it possible for the researchers to later reinstate typical expression levels of the gene in adult mice and alter their behavior. Social alterations : Unlike control mice with two working copies of the gene, the SCN2A model mice preferred to spend time in an empty chamber instead […]

Average wait time for autism diagnosis in Colorado is three years; non-profit working to shorten that significantly

Firefly Autism (Firefly Autism) COLORADO SPRINGS, Colo. (KKTV) – The average wait time for an autism diagnosis in Colorado is reportedly three years. One Colorado non-profit is working to shorten that signficantly. 11 News spoke with Firefly Autism , a non-profit organization with campuses located in Colorado Springs and Denver. Firefly Autism has a three-step process for diagnosis including interviews, evaluations, and more, with a wait time of approximately 2 weeks. “When thinking about early intervention and the importance of early intervention, we want to get this diagnosis done as early as possible and if a kiddo is four years old, and they’re on a wait list for two years, they are missing vital periods of their development,” said Dr. Tanner Simpson of Firefly Autism. According to Firefly Autism, it specializes in the comprehensive psychological testing and evaluation for toddlers, children, adolescents, and adults experiencing a variety of developmental behavioral, and learning differences. This includes challenges associated with developmental delays, intellectual, learning, and other developmental disabilities, such as autism spectrum disorders. Firefly Autism also does home-based services for adults. “These individuals we’re working with provide so much to society and they can offer so much to the community and […]

Earlier autism diagnosis associated with greater trait improvement

Children who are diagnosed with autism before 2 and a half years of age show greater gains in their social skills , on average, than children who are diagnosed later, according to a new study. Early diagnosis is widely thought to be important because it makes it possible to treat children early, yet there has been little evidence that early treatment benefits autistic children, says lead investigator Ilan Dinstein , associate professor of cognitive and brain sciences at Ben-Gurion University of the Negev in Beersheba, Israel. Autistic children who receive early intervention as part of a clinical trial often display promising gains, but those treated in community settings do not typically experience as many benefits , previous studies show. This gap raised a burning question for Dinstein and his colleagues: “Is there a reason to hurry and perform the diagnosis early in situations where intervention is messy, heterogeneous and not delivered by world-renowned experts?” he says. The answer, according to the results Dinstein and his colleagues published in October in Autism , appears to be yes. “I hope that these and related findings will put continued pressure on advisory bodies that produce guidelines, and also on insurers to push […]

What is autism and what are the symptoms in children?

AUTISM spectrum disorder is a condition which can affect a person’s communication skills and their ability to socialise. It affects about one per cent of the population, but how can you tell if your child might be showing signs of autism? Autism spectrum disorder (ASD) is three to four times more common in boys than in girls (stock image) Here’s all you need to know about people with ASD, the signs and symptoms and what support is available in the UK. What is autism? Autism spectrum disorder (ASD) is an incurable, lifelong developmental condition that affects how people perceive the world and interact with others. It affects around one in 100 people in the UK and is three to four times more common in boys than in girls. Many people with ASD find it hard to understand other people’s feelings and emotions, and they may have difficulty holding conversations. When they are young, their language development may take longer and they can struggle to use facial expressions, using gestures to communicate instead. They may also find it hard to connect with other people and to hold eye contact with unfamiliar individuals. Many children with ASD like to follow a […]

The impact of noise and soundscape on children with autism in schools

Health Wellbeing and Sustainable Buildings MSc student Alex Mason reviews the impacts of noise and soundscape for students with Autism Spectrum Disorder in schools, including design recommendations. It is estimated that for every 100 children in the UK, at least one will be diagnosed with Autism Spectrum Disorder (ASD). With approximately 71% of these children educated within mainstream schools (1), it is essential that we design inclusive schools as standard to meet the needs of every child requiring education. William Melnick defined ‘noise’ as “the unpleasant sounds which distract the human being physically and physiologically”. Research states that younger children are much more susceptible to poor acoustic conditions than adults, with children in their primary school years experiencing greater detrimental effects of noise and reverberation (2). Noise does not affect all children equally and pupils with autism are often very sensitive to specific types of noise (3). Whilst some children may not be disturbed by a specific noise source, children with autism would cover their ears because the same level of noise is so painful (3). Short-term management of these issues has seen children using ear defenders to avoid distress, something which should not be required in a school […]
