Many anxiety disorders, such as social anxiety disorder and generalized anxiety disorder, are not commonly diagnosed in people with ASD because such symptoms are better explained by ASD itself, and it is often difficult to tell whether symptoms such as compulsive checking are part of ASD or a co-occurring anxiety problem. The prevalence of ...
Rett syndrome and Fragile X syndrome (FXS) are single gene disorders related to autism with overlapping symptoms that include deficient neurological development, impaired language and communication, difficulties in social interactions, and stereotyped hand gestures. It is not uncommon for a patient to be diagnosed with both autism and Rett ...
These variabilities have led to the exploration of the clinical and molecular convergence between Rett syndrome and autism. [60] Sleeping and language impairments, seizures, and developmental timing are common in both autism and Rett syndrome (RTT). Because of these phenotypic similarities, there has been research into the specific genetic ...
More specifically, prevalence estimates of catatonia among people with neurodevelopmental disorders (of which autism is one) have ranged from 6-20.2%, with the mean estimate falling at 9%; [1] similarly, in a recent meta-analysis of 12 studies of autistic catatonia, Vaquerizo-Serrano et al. suggest that catatonia is found in 10.4% of autistic ...
A high-functioning group (around 25 percent) whose symptoms more or less overlap with that of what was Asperger syndrome, while also not meeting the then current criteria for autism spectrum disorder, but who completely differ from those with Asperger syndrome in terms of having a lag in language development and/or mild cognitive impairment ...
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.
The study found a far lower autism rate in younger adults than in children, but it also found that autism is increasing at a faster pace among those adults. The rate of autism for adults ages 26 ...
A social disorder is a type of psychiatric condition that includes social deficits and affects social functioning. [1] [2] Examples of social disorders include social phobia (social anxiety disorder), autism spectrum disorders, schizophreniform disorders like schizophrenia and schizoid personality disorder, and certain other personality disorders.
