Genetic condition awaiting consideration - Autism Spectrum Disorder
Autism comprises a clinically heterogeneous group of disorders –referred to as “autism spectrum disorders” (ASD).
ASD share common features of impaired social relationships, impaired language and communication and repetitive behaviour or a narrow range of interests.
Symptoms develop gradually, although approximately 30% have a "regressive" onset usually between ages 18 and 24 months.
About 50%-70% of children with autism are identified as intellectually disabled by nonverbal IQ testing and approximately 25% develop seizures.
There are two type of autism: complex (i.e., presence of dysmorphic features and/or microcephaly) or essential (i.e., absence of physical abnormalities and microcephaly).
About 25% of children that have been diagnosed with ASD at age two to three years subsequently begin to talk and communicate, and by age six to seven years blend to varying degrees into the regular school population. The remaining 75% have lifelong disability requiring intensive parental, school, and social support. In Britain, the prevalence of undiagnosed autistic adults is found to be 1%.
