How has autism research advanced?
Autism Spectrum Disorders (ASD) encompass a broad range of neurodevelopmental conditions in individuals. Some individuals can be more affected by sensory challenges and others by repetitive behaviors. According to the World Health Organization, there are multiple factors, including genetic and environmental influences, contributing to the development of autism. In addition to these factors, how has autism research advanced?
Although the exact cause of autism is still unknown, and the idea of “a cure” is a significant myth, there have been considerable advances in understanding this condition in the last decade. These advances include more comprehensive diagnosis and effective treatments, such as Applied Behavior Analysis (ABA) therapy, for addressing the more challenging aspects of autism.
We invite you to join us in reviewing the most critical findings in autism research on this blog by ABA Centers of Washington.
Is Autism Heritable?
Past studies have indicated a genetic influence in the onset of ASD, suggesting that it could be hereditary. A significant study published in 1977 by the Journal of Child Psychology and Psychiatry highlighted a notable difference in autism concordance between identical (monozygotic, MZ) and fraternal (dizygotic, DZ) twins. This discrepancy was even more pronounced in cases of cognitive disorder, emphasizing the solid hereditary influences in autism development.
More recently, research from the Proceedings of the National Academy of Sciences unveiled a unique pattern among children with autism from multiplex families. This pattern revealed an increased frequency of rare inherited protein-truncating variants within recognized autism risk genes. The study also indicates how ASD polygenic risk is transmitted from nonautistic parents to their autistic children, especially those inheriting these rare variants. These findings suggest an interaction of genetic factors in the offspring, providing insights into why these rare variants may not be as penetrant in parental generations.
The study further explored the relationship between the ASD polygenic score (PGS) and the transmission of social dysfunction and language delay. This connection suggests that language delay might be an inherent biological feature of ASD, challenging the existing belief that it’s not a core clinical criterion.
It’s crucial to remember, however, that while genetics can contribute to the development of autism, the condition itself is complex. A blend of genetic, environmental, and neurological influences shapes it.
Autism Genetics Study
The causes of autism are still not fully understood, but research suggests that both genetics and environment may play a role. The study titled “Assembled CRISPR Screens Reveal the Impact of Disease Genes in Human Neurodevelopment” discusses the role of disease genes in developing neurodevelopmental disorders, particularly autism.
According to the findings, the assembly of cortical circuits encompasses the generation and migration of interneurons from the ventral to the dorsal forebrain. Researchers have linked the abnormal development of these interneurons with ASD.
The study also identified that of the 425 genes linked to NDD, 46 interrupted the development of interneurons. This extensive gene mapping gives a more profound insight into the intricate processes implicated in conditions such as autism.
Tactile Sensitivity and Perception
The spectrum presents a wide array of tactile sensitivities, which have become a significant focus in clinical and research settings. The way these sensitivities manifest can vary greatly. For instance, some individuals with ASD might exhibit hypersensitivity to touch, finding everyday stimuli overwhelming or even distressing. On the other hand, some may show hyposensitivity, responding minimally or not at all to tactile stimuli, including reduced responses to pain or temperature.
Recent studies have shed new light on these sensory processing abnormalities, among the most common behavioral phenotypes observed in autism, and even form part of its diagnostic criteria. A report from Current Psychiatry Reports has highlighted that mice carrying mutations in ASD-related genes such as Shank3, Fmr1, UBE3A, and Mecp2 display abnormalities in their tactile responses. Interestingly, these abnormalities stem more from changes in the peripheral nervous system (PNS) than from alterations in central nervous system (CNS) processing, challenging previous beliefs.
This research underscores the growing body of evidence suggesting that peripheral mechanisms might contribute significantly to core ASD symptoms, including social deficits and tactile sensory sensitivities. It also provides invaluable insights into the complexities of ASD, emphasizing the need for further investigation into the role of ASD-related gene mutations in sensory processing abnormalities.
What is the Future of Autism Research?
Autism research is making progress on different fronts to improve our comprehension of the disorder and enhance the lives of those affected. Despite this, a significant challenge that still exists is ensuring that individuals with autism and their families receive adequate support.
The future research has two main goals. The first one is to understand the causes, physiology, and genetic aspects of autism. The second goal is to improve children’s independence with autism spectrum disorder. ABA therapy is crucial as it can help improve language and communication skills, increase attention, and reduce unwanted behaviors.
In conclusion, the future of autism research involves a multifaceted approach that includes providing resources for families and professionals, studying early intervention techniques, and investigating ways to improve behavioral independence in children with ASD.
