A neurodevelopmental disorder is described as genetic or acquired biological disability in the functioning of the brain that is responsible for the dysfunction in the child’s behaviour. It also affects the memory and ability to learn such as mental retardation, dyslexia, cerebral palsy and autism etc. It addresses the complexities of the of the central nervous system development in children. There are four major categories of these disorders which include: cognitive dysfunction, behavioural problems, motor dysfunction, and seizures. The neurodevelopmental behavioural disorder includes physical as well as functional abnormalities. The migration of neurons may be affected by exposure to x-ray radiation, alcohol or methylmercury.
Autism spectrum disorder (ASD) and attention deficit and hyperactivity disorder (ADHD) are the two most common neurodevelopmental disorders observed in childhood. The DSM-5 accepts a combined diagnosis of ADHD and ASD, while the DSM-IV did not. The aim of this study was to identify and evaluate the adaptive profile of children and adolescents with a diagnosis of comorbid ADHD and ASD, in comparison with adaptive functioning in subjects with a diagnosis of only ASD or ADHD.
