This lower-than-normal B12 profile persisted throughout life in the brain tissues of patients with autism. These deficiencies are not visible by conventional blood sampling. [104] [105] As for the classic deficiency of vitamin B12, it would affect up to 40% of the population, its prevalence has not yet been studied in autism spectrum disorders ...
Mind-blindness is defined as a state where the ToM has not been developed in an individual. [1] According to the theory, non-autistic people can make automatic interpretations of events taking into consideration the mental states of people, their desires, and beliefs.
Childhood disintegrative disorder (CDD), also known as Heller syndrome and disintegrative psychosis, is a rare condition characterized by late onset of developmental delays—or severe and sudden reversals—in language (receptive and expressive), social engagement, bowel and bladder, play and motor skills.
There is no scientific consensus on its classification as a personality trait, medical symptom, or mental disorder. [7] [8] Alexithymia occurs in approximately 10% of the population and often co-occurs with various mental or neurodevelopmental disorders. [9] It is present in 50% to 85% of individuals with autism spectrum disorder (ASD). [10]
Echopraxia is a typical symptom of Tourette syndrome but causes are not well elucidated. [1]Frontal lobe animation. 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.
X-ray image of deep brain stimulation, an experimental procedure used to treat disorders such as OCD and depression.. Neuropsychiatry is a branch of medicine that deals with psychiatry as it relates to neurology, in an effort to understand and attribute behavior to the interaction of neurobiology and social psychology factors.

Specifically, proponents of the imprinted brain hypothesis propose that autism spectrum disorders are caused by paternal overimprinting, while schizophrenia spectrum disorders are caused by maternal overimprinting; they point to a number of supposed correlations and anticorrelations seen between the disorders and other traits to support the ...
