Autism and Twin Studies (2)
Professor Pat Levitt explains that twin studies of autism show that it is a highly genetic disorder.
The genetic basis for autism, in terms of autism vulnerability, is clear. The best way to look at that is from studies of identical twins. If you look at identical twins, if one twin has autism, the chance of the other twin having autism is about eighty percent. Itâ€™s very, very high. As a comparison to schizophrenia, if one twin has schizophrenia, the likelihood of the other twin having it is about 45 percent which is still relatively high. But compared to autism, you can see autism seems to have a larger genetic component to it.

Professor Pat Levitt explains that the genetic basis for ADHD is evident from twin and family studies.
Professor Pat Levitt comments that people with genetic vulnerability to schizophrenia often have developmental problems from an early age.
Professor Pat Levitt discusses that although it shares genes with other disorders, schizophrenia is likely caused by unique combinations of genes.
Recent research into the causes of autism suggests that the disorder is predominantly genetically determined.
Professor Daniel Weinberger explains that while genes play an important role in susceptibility to schizophrenia, environmental interactions are also important.
Professor Pat Levitt explains that the sooner autism is diagnosed, the more effective the intervention.
Professor Pat Levitt explains that while schizophrenia is rarely seen in childhood, there are early signs of developmental problems.
Brain scans of close relatives of children with autism reveal clear abnormalities that parallel those seen in autism.
In this review of schizophrenia, the authors show how our growing knowledge of causal factors offers hope for successful preventive measures.
FOXP2 is a gene associated with autism and language disorders.
