diagnosis
What tests or scans do doctors use to diagnose Alzheimer's disease?
Doctors use tests to check for memory problems. These tests look at how you think, remember, and use words.
Doctors use thinking, memory, and language tests to check for memory problems. People who forget things more often than others their age may have mild cognitive impairment, or MCI.
Memory problems can have many different causes. These include certain medicines, a stroke, depression, or head injuries. Blood clots or growths in the brain can also affect memory. So can kidney, liver, or thyroid problems. Testing helps your care team find the real cause. Some causes can be managed or even reversed.
Alzheimer's disease is not a normal part of aging. It can be mistaken for normal aging changes at first. MCI can sometimes be an early sign of Alzheimer's disease.
Depending on the results, you may need to see a specialist for more tests. If you are worried about forgetfulness, talk with your care team. They can do tests. They also check for changes in your memory and thinking over time.
