An investigation of clozapine in the treatment of acute and chronic schizophrenia and gross behaviour disorders.
Fifty-two mental hospital cases of acute and chronic schizophrenia and gross behaviour disorders were investigated and observed for 6-12 months during treatment with clozapine. Three-quarters of the acute cases recovered with full occupation capacity. Two-thirds of the chronic cases improved markedly. Antisocial behaviour was controlled in 12 out of the 13 behaviour-disordered group. The improvement in initiative and social capacity was striking and appeared to be due to improved awareness of the environment and the acquisition and handling of useful knowledge. The response to clozapine appears to be specific and relapses occurred when maintenance medication was stopped. It is of value in treating temper states in epilepsy and has the advantage of not causing extrapyramidal symptoms and side-effects are slight after the first week. Maximum improvement may not be reached before 8 weeks. Thereafter the maintenance dose can be small and fluctuations in the illness do not seem to occur. The dosage, side-effects and precautions are discussed. A rating system to display the effect of clozapine on individual parameters as well as on the over-all state was devised for this study.
