Transcript of Autism
& Effects Signs & Effects Continued... Mode of Inheritance There are many causes of autism, and because there are a lot it makes it harder for scientists and researchers to identify just one cause of it. This disease branches out into many aspects which means studying view in close detail. Most likely, ASD is the cause of both genetics and environment. Researchers have identified a number of genes associated with the disorder; these include different regions of chromosome 7 & 15. Studies of people with ASD have found irregularities in several regions of the brain and can also be due to severe brain damage when young. As well, learnings suggest that people with ASD have abnormal levels of serotonin or other neurotransmitters in the brain. These abnormalities suggest that autism could result from the disruption of normal brain development in early stages caused by defects in genes that control brain growth and that regulate how brain cells communicate with each other. Pictures Video Clip Mode of Inheritance - Pedigree The studies of twin and families strongly suggest that some people have a genetic predisposition (more likely) to autism. Identical twin research show that if one twin is affected there is up to a 90 percent chance the other twin will be affected. In families with one child with ASD, the risk of having a second child with the disorder is approximately 5 percent (a 1 in 20 chance). In some cases, parents and other relatives of a child with ASD show mild impairments in social and communicative skills or engage in repetitive behaviors. Evidence also shows that some emotional disorders, such as a strong bipolar disorder, occur more frequently in the families of people with ASD. Treatments There is no cure for Autism, but therapies and behavioral interventions are designed to help with specific symptoms and can bring about substantial improvement. The ideal treatment plan coordinated therapies and interventions that meet the specific needs of individual people. No two autistic people are alike so doctors and scientists need to take careful care when diagnosing and finding specific cures for each case. There are however educational & behavioral therapies. Therapists use highly structured and intensive skill-oriented training sessions to help children develop better social and language skills. Also, doctors may prescribe medications for treatment of specific autism-related symptoms, such as anxiety, depression or obsessive-compulsive disorder. As well, antipsychotic medications are used to treat severe behavioral problems.
