The etiology of these disorders can be infectious, toxic, genetic, traumatic, and ischemic, and related to other chronic pathophysiologies. The occurrence may be at birth, which may confer a lifelong disability, or may occur in middle or late life, which may result in progressive disability and death. Neurological disorders may have an insidious onset or have symptoms that are nonspecific, making classification difficult. Early stages of some disorders are characterized by a variable presentation or by subtle signs and symptoms that are difficult to detect or that go unrecognized. Individuals often ignore symptoms until function is impaired. Some disorders in children may be developmental and may go undetected until the children reach the age at which deficits could be assessed. Hence, recognition, diagnosis, and progression of neurological symptoms may affect the true magnitude and onset of neurological disorders.
