Are there any genetic causes of intellectual disabilities?
Genetic Causes of Intellectual Disabilities Many intellectual disabilities (ID, formerly mental retardation) are caused by genetic abnormalities. The two most common genetic causes of intellectual disabilities are Down syndrome and Fragile X syndrome. Down syndrome (or Down’s syndrome in the UK)
What are the causes of organic mental disorders?
Causes. Low oxygen in the blood, high amounts of carbon dioxide in the body, strokes, brain infections, and heart infections can lead to an organic mental disorder as well. Degenerative disorders like Parkinson’s disease, Alzheimer’s disease, Huntington disease, and multiple sclerosis may also be contributing factors.
What are the causes of chronic organic brain syndrome?
