Neurobiological Perspectives on Autism Essay -- Biology Essays Researc

Neurobiological Perspectives on AutismAutism is a pervasive developmental disorder characterized by restricted, repetitive, and stereotyped patterns of behaviour, along with severe impairments in trilateral social interaction, verbal and non-verbal communication, and cognitive development (1,2,3). If the brain is responsible for behavior then it should follow that disordered autistic behaviors should be explainable in terms of brain abnormalities and disordered neurobiological processes. While findings are more often than not speculative and the etiology of the disorder remains somewhat of an enigma, there is evidential evidence that autism is associated with neurobiological dysfunction. Autistic individuals are often highly socially withdrawn to the extent that they whitethorn appear to live in a world of their own. Infants typically fail to develop normal attachments to parents or caregivers. They may seem indifferent to others gestures of affection towards them, and may even r esist organism held or otherwise engaged in physical or wound up interaction.
