Exams and Tests
Alzheimer's disease is diagnosed after other conditions are ruled out. Your doctor will use a variety of tests to do this.
It usually is helpful to have a family member or someone in close contact with the person present at the appointment. A family member may be able to provide the best information about how a person's day-to-day functioning, memory, and personality have changed.
The doctor will use a medical history and physical exam to help find out if a physical problem may be causing the person's dementia symptoms. Sometimes another problem can cause the same symptoms as Alzheimer's.
Lab tests may be done to rule out other possible causes of a person's symptoms, such as levels of certain minerals or chemicals in the blood, liver disease, abnormal thyroid levels, or nutritional problems, such as folate or vitamin B12 deficiencies. Treatment for these conditions may slow or reverse mental decline.
