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.
Genetic factors may be the most significant cause of autism. Early studies of twins had estimated heritability to be over 90%, meaning that genetics explains over 90% of whether a child will develop autism. [1] This may be an overestimation, as later twin studies estimate the heritability at between 60 and 90%.
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.
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] Sensory abnormalities are also included in the diagnostic manuals ...
Although linked with early childhood, the symptoms can appear later as well. Symptoms can be detected before the age of two and experienced practitioners can give a reliable diagnosis by that age. However, official diagnosis may not occur until much older, even well into adulthood.
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.
A new study suggests diagnoses have increased at a faster clip among younger adults over the past decade. Autism spectrum disorder spiked 175% among people in the U.S. from 2.3 per 1,000 in 2011 ...
Classic autism, also known as childhood autism, autistic disorder, or Kanner's syndrome, is a formerly diagnosed neurodevelopmental disorder first described by Leo Kanner in 1943.
