Excerpt from Bulletin of the Massachusetts Commission on Mental Diseases<br><br>Yet the number of actual entities (ih the medical sense of this term as a kind of collection of symptoms) in which delusions do form a central feature makes a formidable list. I may limit myself to the following actual or possible entities: paranoia, the paranoid form of dementia praecox, and the somewhat closely allied paraphrenia of Kraepelin's recent formulation, the ao-called acute alcoholic hallucinosis, or insanity of alcoholic origin, a number of forms of pre-senile psychoses, some forms of senile psychoses, to say nothing of various forms of syphilitic mental disease, as also manic-depressive psychosis, various mild or severe psychopathic conditions not ordinarily considered to amount to frank mental disease, and even such apparently remote entities, or groups of entities, as are found under the caption of epilepsy and feeble-mindedness.<br><br>About the Publisher<br><br>Forgotten Books publishes hundreds of thousands of rare and classic books.
