The purpose of screening is early diagnosis and treatment. Screening tests are usually done for people without any current symptoms, but who may be at high risk for certain diseases or conditions.
There are several tests that doctors may use to screen for Alzheimers disease. Examples include:
Genetic testing is available, but it is not routinely used in most patients. It may be done in patients with a family history of early-onset Alzheimers. Researchers are also studying whether specialized imaging tests would be helpful in screening for Alzheimers disease. Cerebrospinal fluid (CSF) evaluation via a lumbar puncture may play a role in the diagnosis of Alzheimers disease.
