New ways to assess brain function in Parkinson disease
Neurology recent issues
Over the past 40 years, our understanding of the brain and its function has dramatically changed. Much of this has been due to new ways of looking at the living brain. It was in the 1970s that computed tomography scans (CT or CAT scans) were first used. By the 1980s CAT scans were commonplace. Magnetic resonance imaging (MRI) was developed in the 1980s. It became widely available thereafter and is now a standard way of looking at the brain and other parts of the nervous system. CAT and MRI have allowed scientists to study the structure of the living brain in detail. In addition, doctors and scientists have been able to study neurologic disease in ways that previously were not possible.
