Genetic studies in children with intellectual disability and autistic spectrum of disorders
Autism is one of the five disorders that falls under the umbrella of
Pervasive Developmental Disorders (PDD) or Autism Spectrum Disorder
(ASD), a category of neurological disorders characterized by "severe
and pervasive impairment in several areas of development." ASD is
characterized by varying degrees of impairment in communication skills,
social interaction and restricted, repetitive stereotyped patterns of
behavior. The five disorders under PDD are autistic disorder,
Asperger\u2032s disorder, childhood disintegrative disorder,
Rett\u2032s disorder and PDD-not otherwise specified. ASD can often be
reliably detected by the age of 3 years and, in some cases, as early as
18 months. The appearance of any warning signs of ASD is reason to have
the child evaluated by a professional specializing in these disorders
