A system for rating the severity of senility.
Although the development of senility in members of the aging population is not invariable or predictable at a specific age, the incidence is high and presents a constant problem for those responsible for the care of this group. A simple classification (Classes I-VI) is suggested to describe the severity of senility. The crucial dividing line in the estimation of severity lies at mid-point on the scale, i.e., between Classes III and IV. Class III (direction) represents patients who can accomplish activities if told what to do, and Class IV (assistance) represents patients who need physical help for the activities  of daily living. On either side are Classes I and II (minor manifestations) versus Classes V and VI (ambulatory or bedridden patients, unable to communicate appropriately). The severity is estimated in terms of the needs of the patient.
