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 ]
Anencephaly is the absence of a major portion of the brain, skull, and scalp that occurs during embryonic development. [1] It is a cephalic disorder that results from a neural tube defect that occurs when the rostral (head) end of the neural tube fails to close, usually between the 23rd and 26th day following conception.

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.
The mirror neuron system (MNS) theory of autism hypothesizes that disrupted development of the MNS impairs autistic people's ability to imitate others, leading to core autistic features of social impairment and communication difficulties. In animals, the MNS activates when an animal performs an action or observes another animal perform the same ...
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.
For many adults with autism, finally getting a diagnosis is a relief. (Photos, left to right, courtesy of Sarah Nannery, Gavin Bollard, Rebecca Dingwell/Snickerdoodle Photography and Morgan Harper ...
Rett syndrome brain samples and autism brain samples show immaturity of dendrite spines and reduction of cell-body size due to errors in coupled regulation between MECP2 and EGR2. [62] However, because of the multigene involvement in autism, the MECP2 gene has only been identified as a vulnerability factor in autism. [63]
An adult autism diagnosis is an identity builder, minting new members of a growing community and creating a sense of belonging for those grappling with loneliness. For adults, autism diagnosis can ...
