This group should receive the occasional case which after investigation and observation gives no evidence of having had a psychosis. The only difficulty likely to be encountered in the statistical reports will arise in the grouping of patients who have recovered from a psychosis prior to admission. In such cases, if the history, the commitment papers or the patient's retrospective account show that a psychosis actually existed immediately before admission, that is. at the time of commitment, then the case should be considered as having suffered from a mental disorder, and classification under the appropriate heading should be made.

If it is determined that no psychosis existed, then the condition which led to admission should be specified. The following come most frequently into consideration:

(a) Epilepsy without psychosis.

(6) Alcoholism without psychosis.

(c) Drug addiction without psychosis.

(d) Constitutional psychopathic inferiority without psychosis.

(e) Mental deficiency without psychosis. (f) Other conditions (to be specified).
