The inebriate may be also classed in the same way. There are perhaps a few cases in which the habit of taking alcohol is absolutely acquired, but they are comparatively few. There are also a few cases of nervous prostration or functional nervous conditions from overwork, from a depleted condition, where the nervous condition comes on; and we may say it is acquired, and the prognosis in both of these cases is good. It requires but little effort to put them on their feet. Then we have that larger class of neurasthenic or functional nervous conditions, belonging to the second group, in which the nervous disease, as well as the inebriety, is partially acquired and partially hereditary. There is a large class here. They have an unstable nervous system, and whether they drink or break down depends a great deal upon the environment and physical condition. This type of inebriate must be treated along the same broad lines that we treat a person who is a neurasthenic, who is subject to repeated nervous breakdowns. There is another type which, unfortunately, is rather large; and this is the wholly hereditary, and in this type we may classify the dipsomaniac. I have looked for a long time upon dipsomania as a periodical nervous disturbance, similar to periodical attacks of migraine or epilepsy, or periodical attacks of insanity. Often where a son is an inebriate we find a history of migraine in the mother. Very often there is insanity, and very often there is epilepsy, so that when we come to consider the dipsomaniac we have a tremendous problem. He does not drink for the fun of it, but chiefly because of mental depression, mental restlessness, which is so great that he turns to alcohol to buoy up his spirits and get rid of the feeling which rather than suffer with, he would often prefer to die. I have a man of that description who came to me, and said that at a certain time he became depressed and suspicious, began to hate himself, went along the back streets, absented himself from his usual associates, and always did this at the beginning of his drinking bout. That is the case with all dipsomaniacs. It is a disease similar to epilepsy, and our success in treating this type is just about as good as in treating epilepsy. It is not the alcohol: it is an inherited condition; it is a periodical nervous disturbance, just as epilepsy and migraine are.
