A neurological disorder is any medical problem that affects the nervous system. Your body’s nervous system includes your brain, spinal cord, and other nerves. Problems with the structure or function of any part of the nervous system can lead to a neurological disorder.
Symptoms of a neurological disorder can be mild, such as muscle weakness, poor coordination, or changes in thinking patterns. Symptoms can also be more noticeable, such as seizures, pain, and intellectual disability. People with a neurological disorder can have just one or many of these symptoms. Although most neurological disorders are individually rare, when they are combined, over 6 million people in the U.S. are affected.
