Introduction
Epidemiology
- Prevalence of autism spectrum disorders (ASDs) is 1 in 100.
- The prevalence of mental retardation in idiopathic autism is �60%; when the autism spectrum is taken as a whole, prevalence of MR is 30%.
- Epilepsy has long been associated with autism, but estimates of prevalence of seizure disorder vary from 5% to 44%.
Risk Factors
Taking SSRI's 1 year before delivering a baby (during pregnancy and up to 3 months before conception) doubles the risk of ASD in the offspring; risk is even higher (adjusted OR=3.8) if the expecting mother is taking SSRIs during the first trimester. (1)
Screening
M-CHAT: screen children for PDD as young as 18mo.
