    • Common forms of dementia include Alzheimer's disease, Parkinson's disease, Korsakoff's syndrome and vascular dementia--common in stroke victims.

    Testing

    • Testing for dementia includes a physical and mental examination. Cognitive tests are given to determine function, memory, orientation and reasoning skills. The brain may be scanned using MRI and CT testing.

    Prevention

    • According to the Mayo Clinic, high levels of alcohol consumption, smoking as well as high levels of cholesterol and blood pressure may increase the risk of a person developing dementia. Control the above factors to decrease your risk of of developing dementia.
