In a recent article by Tarjan et al.1 the use of chlorpromazine in mentally deficient patients was reviewed, possible complications from its use were well outlined, and the need for a double-blind research study to measure its objective effectiveness was indicated.

These authors felt that the two-month period of treatment with the drug followed by two-months' use of a placebo was "too brief to determine how well improvement will be sustained."2 They did not attempt to compare the effectiveness of chlorpromazine with that of reserpine.
