Your doctor will ask about your symptoms and medical history. A physical exam will be done. This includes a thorough neurological evaluation along with a series of tests. Other tests may include those which will increase or decrease the likelihood that you have Alzheimers disease. Your doctor will also perform tests to eliminate the possibility of other conditions causing the dementia.
These tests help determine if you have signs of dementia, how severe the dementia is, or to look for other causes of dementia. They may include:
Additionally, electroencephalogram (EEG) is a test that evaluates and follows the electrical activity of the brain. It is not a common test for evaluating most dementias, but it may be done.
Blood and urine tests may be ordered to look for other conditions that cause dementia. The tests may include:
Genetic tests can look for markers that increase your risk for early-onset Alzheimers. Your doctor may recommend this test if you have family members with this condition.
