title: Norepinephrine and gamma-aminobutyric acid in amyotrophic lateral sclerosis.
abstract: Patients with amyotrophic lateral sclerosis have increased levels of the neutrotransmitter norepinephrine in blood and cerebrospinal fluid and depressed levels of the inhibitory neurotransmitter gamma-aminobutyric acid in cerebrospinal fluid. These neurochemical alterations are most marked in patients bedridden with advanced disease, appear interrelated, and lead to cardiovascular alterations in patients with amyotrophic lateral sclerosis.
