The autism spectrum may comprise a small set of disorders that converge on a few common molecular pathways, or it may be a large set of disorders with diverse mechanisms. [16] Autism appears to result from developmental factors that affect many or all functional brain systems. [17]
There are many conditions comorbid to autism spectrum disorder, such as attention deficit hyperactivity disorder, anxiety disorders, and epilepsy. In medicine, comorbidity is the presence of one or more additional conditions co-occurring with the primary one, or the effect of such additional disorders. Distinguishing between ASD and other ...
Autism, or autism spectrum disorder [a] (ASD), is a neurodevelopmental disorder characterized by repetitive, restricted, and inflexible patterns of behavior, interests, and activities, as well as deficits in social communication and social interaction, and the presence of high or low sensory sensitivity.
Autism in Adulthood is a quarterly peer-reviewed academic journal covering research across a range of disciplines on all aspects of autism spectrum disorders in adults. It was established in 2019 and is published by Mary Ann Liebert. The founding editor-in-chief is Christina Nicolaidis (Portland State University). [1]
Autism spectrum disorder is a disorder of the many parts of the brain. Structural changes are observed in the cortex, which controls higher functions, sensation, muscle movements, and memory. Structural defects are seen in the cerebellum too, which affect the motor and communication skills. [ 14 ]
Two implications of this theory are that children and adults with an autism spectrum disorder (ASD) would be more reactive to sensory stimuli than the standard population, and they may be slower to habituate to stimuli. There is some laboratory evidence of differences in physiological responses of individuals with ASD compared to non-autistic ...
The relationship between autism and memory, specifically memory functions in relation to autism spectrum disorder (ASD), is an ongoing topic of research. ASD is a neurodevelopmental disorder characterised by social communication and interaction impairments, along with restricted and repetitive patterns of behavior.
Some examples of ASD signs are specific or repeated behaviors, enhanced sensitivity to materials, being upset by changes in routine, appearing to show reduced interest in others, avoiding eye contact and limitations in social situations, as well as verbal communication.
