Clinically significant symptoms of these two conditions commonly co-occur, and children with both sets of symptoms may respond poorly to standard ADHD treatments. Individuals with autism spectrum disorder may benefit from additional types of medications. [13] [14] The term AuDHD is sometimes used for those with both autism and ADHD.
The severity of symptoms and functional impairment vary between individuals. [3] There are many known environmental, genetic, and biological causes of autism. Research indicates that genetic factors predominantly contribute to its appearance. The heritability of autism is complex and many of the genetic interactions involved are unknown. [1]
Autism spectrum disorder [a] (ASD), or simply autism, is a neurodevelopmental disorder "characterized by persistent deficits in social communication and social interaction across multiple contexts" and "restricted, repetitive patterns of behavior, interests, or activities". [11]
The amygdala, cerebellum, and many other brain regions have been implicated in autism. [15]Unlike some brain disorders which have clear molecular hallmarks that can be observed in every affected individual, such as Alzheimer's disease or Parkinson's disease, autism does not have a unifying mechanism at the molecular, cellular, or systems level.
Furthermore, the presence of autism can make it harder to diagnose coexisting psychiatric disorders such as depression. [9] Diagnosing will be much harder in adults, since most people with ASD who reach adulthood undiagnosed, learn diverse (and often intense) masking techniques which make external diagnosis almost impossible.
In the animal models, the significant effects of VPA in causing ASD-like symptoms was demonstrated mainly in rats exposed to VPA on gestation day 12.5, not in other gestation days like day 9, 14.5, etc. [47] [48] The ASD-like symptoms of mice included decreased distressed pup calls, decreased social exploration, decreased social behaviors ...
Autism cases spiked 175% among U.S. residents from 2011 to 2022. The rates climbed at a faster rate among young adults.
Relationship Development Intervention (RDI) – a trademarked proprietary treatment program for autism spectrum disorders (ASD), based on the belief that the development of dynamic intelligence is the key to improving the quality of life for individuals with autism. Son-Rise – a therapy encouraging adults to connect with autistic children.
