Dementia in ALS (Lou Gehrig's Disease) (cont.)

Exams and Tests
Changes in personality, behavior, or cognitive functions have many different causes. The causes vary by age, sex, and various other factors. Your health care provider will have the difficult job of sorting out all the possible different causes of your symptoms. He or she will ask many questions, perform examinations, and conduct tests to try to pinpoint the cause.
The medical interview will include questions about your symptoms and how they started, your medical problems now and in the past, your family members’ medical problems, your medications, your habits and lifestyle, and your work, military, and travel history. The physical examination will focus on signs of ALS and other disorders that can cause similar symptoms. It will also include tests of mental status, such as answering questions and following simple directions. Since depression is common in ALS, the medical interview will include an evaluation for depression.
There is no lab test that will diagnose dementia. Blood may be tested for other conditions that can cause dementia symptoms.
Brain scans are the best way to find brain abnormalities that can cause dementia.
