title: T3 toxicosis presented by depression in an elderly woman.
abstract: An elderly patient with thyrotoxicosis complicated by lack of classical clinical signs and normal conventional tests is described. The picture was compounded by development of apathy and depression. This is the second case report of apathetic T3 thyrotoxicosis in the literature. Such a clinical entity can easily be overlooked, but represents one of the treatable disorders of 'old age depression'.
