Brain sections related to autism. Many causes of autism, including environmental and genetic factors, have been recognized or proposed, but understanding of the theory of causation of autism is incomplete. [1] Attempts have been made to incorporate the known genetic and environmental causes into a comprehensive causative framework. [2]
Autism spectrum disorder [a] (ASD), or simply autism, is a neurodevelopmental disorder characterized by repetitive, restricted, and inflexible patterns of behavior, interests, and activities; deficits in social communication and social interaction; and the presence of high or low sensory sensitivity.
Autism is a neurodevelopmental disorder characterized by impaired social interaction and communication, repetitive behaviours, restricted interests, and sensory processing issues. Uta Frith of University College London first advanced the weak central coherence theory in the late 1980s. [ 1 ]
It’s identified by making judgments about a child’s behavior. For decades, the diagnosis was given only to kids with severe problems communicating or socializing and those with unusual, repetitive behaviors. But around 30 years ago, the term became shorthand for a group of milder, related conditions known as ″autism spectrum disorders.”
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.
Pathological demand avoidance (PDA) or extreme demand avoidance (EDA) is a proposed disorder, and proposed sub-type of autism spectrum disorder, defined by characteristics such as a demand avoidance—which is a greater-than-typical refusal to comply with requests or expectations—and extreme efforts to avoid social demands.
GABRB3 null mice exhibit behaviors consistent with autism [29] and multiple genetic studies have found significant evidence for association. [30] Furthermore, a significant decrease in abundance of GABRB3 has been reported in the brains of patients with autism and Rett syndrome. [ 31 ]
The review found that CBT was moderately to highly effective at reducing anxiety in school children with autism spectrum disorder, but that effects varied depending on whether they were reported by clinicians, parents or self-reported. Treatments involving parents and one-on-one compared to group treatments were more effective. [12]
