title: Platelet monoamine oxidase activity in patients with panic disorder.
abstract: Preliminary reports have indicated that platelet monoamine oxidase (MAO) activity is elevated in patients with anxiety disorder. We compared MAO activity in 20 drug-free patients with panic disorder with 20 age- and sex-matched normal controls. MAO activity in patients was significantly higher than in normals. MAO activity was not correlated with age or plasma catecholamine levels. The authors speculate about the possible significance of elevated MAO activity in patients with panic disorder.
