Neuropsychological testing can help your doctor find out how damage to your brain is affecting your ability to reason, concentrate, solve problems, or remember. Doctors use a wide variety of tests for neuropsychological testing. In most cases you will take a series of tests, rather than a single test. This type of testing is most often done by a psychologist with special training in this area. This testing gives your doctor an overall picture of how well your brain works.
Neurophysiologists treat problems of the muscles and nerves and have specialized skills in testing tools such as electroencephalography, or EEG, which measures brain waves. Geriatric neurologists diagnose and treat diseases that affect older adults, including Alzheimerâs disease and Parkinson's disease.
