Neurological disorder

A neurological disorder is a disorder of the body's nervous system. Structural, biochemical or electrical abnormalities in the brain, spinal cord, or in the nerves leading to or from them, can result in symptoms such as paralysis, muscle weakness, poor coordination, loss of sensation, seizures, confusion, painand altered levels of consciousness. There are manyrecognized neurological disorders, some relatively common, but many rare. They may be revealed by neurological examination and studied and treated within the specialities ofneurology and clinical neuropsychology. Interventions include preventative measures, lifestyle changes, physiotherapy or other therapy, neurorehabilitation, pain management, medication, or operations performed byneurosurgeons. The World Health Organization estimated in 2006 that neurological disorders and theirsequelae affect as many as one billion people worldwide, and identified health inequalities and social stigma/discrimination as major factors contributing to the associated disability and suffering.
