HLSC 4808U Lecture Notes - Lecture 4: Asperger Syndrome, Umbilical Cord, Prenatal Diagnosis
Document Summary
Autism is four times more prevalent in males than females. Diagnosis is based on behaviour and the only verified treatment is intensive behavioural therapy. Deficits in social communication and interaction: 2. ) Restricted, repetitive patterns of behaviour, interests, or activities. Both genetic and environmental factors play a role. Prenatal events might account for the cause of asd. Autism and other neurodevelopmental disorders do indeed, have a strong genetic component due to twin study findings. Direct damage to the brain might also have contributed to the other twin in obtaining autism and includes: severe haemolytic disease, delay of breathing more than five minutes, neonatal convulsions. One twin always the autistic one, experienced one or more of those insults. Biological hazards umbilical cord (narrow), birth weight. Perinatal period immediately after birth; factors strongly predisposed to autism development. If autism was completely genetic, than a higher concordance rate is expected with the monozygotic twins. Environmental etiology pathogens offer the strongest evidence.
