Histories of attempted suicides often reveal a depressed, anxious personality, prone to impulsivity. The purpose of this study was to determine a method of drug therapy that would decrease emotional arousal & reduce depression, thus modifying the subject’s reaction to his situational environment. 31 patients exhibiting depressive neuroses were divided into 3 groups in a double-blind experiment using doxepin, imipramine, or diazepam. Rapid improvement was found in the diazepam group. (NBB)
