title: The problem with parsimony: mania and hyperthyroidism.
abstract: A patient is described who developed mania during an episode of hyperthyroidism and later presented again with mania following correction of the thyroid disturbance. Although there are prominent connections between endocrine and mood disorders, clinicians are advised to recall basic medical principles and not assume that an etiological relationship exists in the individual patient until it is proven.
