_Alcoholic Psychosis_ results from continued excesses of drinking. The patient usually resents criticism because he is convinced that his reverses have driven him to drink. The prolonged use of alcohol relaxes inhibitions, produces anti-social actions, and results in more sorrows to drown in more alcohol. Alcoholic psychosis usually begins suddenly with mental confusion, muscle twitches known as tremors, and vivid, visual imaginary thought known as hallucinations. The treatment for such patients includes withdrawal of alcohol and the use of sedative measures. One of these measures is a prolonged bath in a tub of water just below body temperature. Once the patient has recuperated to the convalescent stage, music may be employed. Some alcoholics like to join in group singing, especially if the group is made up exclusively of fellow inebriates. Any encouragement to join non-alcoholics in group singing, or any use of music which may stimulate a permanent interest in a new instrument or diversion would be valuable. These patients lack self-imposed discipline. If music can be used as a discipline, it might lead to decreased drinking. _Arteriosclerotic Psychosis._ As its name implies this is a condition of the aged and is probably related to hardening of the brain arteries. The symptoms may include emotional instability, mental fatigue, disinterestedness, and some loss of memory. The patient begins to look and act old. The treatment consists of custodial care, physical rest, and mental occupation. Music is well suited to this combination. Oldtime favorites played softly for several periods daily is indicated. Obviously, where specific musical numbers are requested they should be played. There is another disease which resembles this called senile psychosis. Usually it can be handled in the home, and is. _Involutional Melancholia_ occurs at an age when certain important biologic functions of the body begin to regress or involute. For women this age is usually forty-five, but for men it can be ten or more years later. The condition is seen especially in those who did not lead an average life previously. A study of the personality of such patients usually shows them to have been uninterested and uninteresting people, with few close friends. An unfavorable experience may bring on worry and unrest. They become saddened and exaggerate the minor sins of their past. They develop false beliefs known as delusions about their surroundings or themselves. At least half of them never recover completely. There is little that can be done for them, except to encourage healthful diets and hygienic regimes to keep them physically well. Some physicians might encourage the use of music for such patients to distract their attention from themselves. Familiar melodies are recommended, because of the age group, old time favorites will be the most suitable.
