=Osteopathic Theory.=—In these psychoses of the older years of life the termination is usually dementia, which means mental enfeeblement, and which results from degenerative changes in the brain substance. As has been shown it is largely a nutritional question and the nutritional condition varies tremendously in different elderly people; it is well known that many old people preserve their brain powers fairly well to the end; on the other hand others fail relatively early, some even in the fifties; these cases of earlier failure are referred to as the “presenile type.” The osteopathic conception would be to find out the source productive of the nutritional disorder and correct it at the very outset, therefore making it quite possible to prevent the disease process from taking place. The prognosis then in the earlier stages is very good. Remarks by Dr. Hildreth While many cooperating factors may be found in the causation of the mental disorder of elderly people, our experience shows there is always very definite disturbance of nutrition and the nutritional centers. We find chief physical interference between the 3d and 8th dorsal vertebræ, most definite as a rule at the 4th, 5th and 6th, with the corresponding ribs on the right side. Contributing causes may be found in other areas, associated with the disturbances of the heart and circulation and of the kidney. In the cardio circulatory disorders we find abnormal spinal conditions in the upper dorsal region and especially the 5th rib on the left side. In the kidney disorders we find the lesions usually at the 10th, 11th and 12th dorsal. The above mentioned areas in general represent the centers of control of the splanchnic nerves and therefore the important processes of digestion, metabolism and assimilation. Specific treatment applied to these points is very helpful and results in marked improvement and indeed in relieving the patient’s symptoms completely when in the earlier stages of the disease. DEFECTIVE CHILDREN By RAYMOND W. BAILEY It is our purpose here to impress on osteopaths the almost unlimited possibilities in the study and treatment of mental conditions of children, which heretofore have been considered hopeless. Osteopathy has demonstrated that it has much to offer to this class of defectives but the profession has not thoroughly appreciated its great possibilities. It has been the custom to send these children to institutions where they have received care with some attempt toward education but with absolutely no effort being made through physical treatment to overcome their debility. We shall show that the osteopathic lesion is of prime importance in these cases, and that we have been slow to realize the efficacy of osteopathic treatment for such seemingly hopeless children. We cannot emphasize too strongly the importance of accepting and treating these cases wherever possible.
