Autistic meltdown describes an intense, often uncontrollable response to an overwhelming situation experienced by some autistic individuals.. Angry outbursts in autistic people have been referred to as meltdowns that manifest as an intense reaction, [1] but such outbursts are different to true meltdowns, which always take some time to recover from.

Simple motor tics are typically sudden, brief, meaningless movements that usually involve only one group of muscles, such as eye blinking, head jerking, or shoulder shrugging.

Those with CDS symptoms typically show a later onset of their symptoms than do those with ADHD, perhaps by as much as a year or two later on average. Both groups had similar levels of learning problems and inattention, but CDS children had less externalizing symptoms and higher levels of unhappiness, anxiety/depression, withdrawn behavior, and ...
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 ...

One theoretical cause subject to ongoing debate surrounds the role of the mirror neuron system (MNS), a group of neurons in the inferior frontal gyrus (F5 region) of the brain that may influence imitative behaviors, [1] but no widely accepted neural or computational models have ...
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.
