There is only a small literature on the psychiatric complications of acromegaly. Manfred Bleuler (1954) reported an acromegalic man who had blunted affect and apathy and suggested that this clinical picture represented a special variation of the endocrine psychosyndrome. Avery (1973) reported a further case of depression and anxiety in association with the illness. There are relevant reviews by Michael and Gibbons (1963), Beumont (1972), Labhart (1974) and Lishman (1978).
