Hundreds of millions of people are affected worldwide by neurological disorders. Neurological conditions are disorders that affect the central and peripheral nervous systems, which are made up of the brain, spinal cord, nerves, and muscles. There are more than 600 neurological disorders, some of which include: Alzheimer’s, stroke, neuropathy, epilepsy, multiple sclerosis, Parkinson’s, and migraines. Neurological conditions are caused by a disturbance of the brain, spinal cord, neurological pathway, or even a single neuron. As a result of this disturbance, neurological symptoms can occur. Some causes of neurological disorders include injury or trauma, genetics, infection, nutrition, or environmental causes. Neurological problems may manifest emotionally and physically. Emotional symptoms of a neurological disorder may be seen as mood swings, depression, or delusions. Some of the physical symptoms of a neurological disorder include muscle weakness, paralysis, loss of sensation, seizures, cognitive impairment, and pain.
