=Prognosis= is the determining, in advance of the fact, of the probable course, duration, or outcome of a disease. A Chiropractic prognosis is a prediction as to the changes which will take place in a case during and after Chiropractic adjustments. =General Prognosis= is an opinion expressed of a disease without reference to any particular case. It is based upon the experience of the profession and the average result obtained with the disease. It furnishes only a basis for consideration of the =special prognosis= of an individual case. This latter must be based upon the general prognosis of the disease and upon study of every modifying factor present in the case, as general vitality, living habits, facility of adjustment, apparent response to early adjustments, and especially an estimate of the amount and kind of damage done to tissue and the probability of its repair. Only general prognosis can be set down as a guide to others. To state even this with certainty and safety many precautions must be observed. All cases included as a basis of conclusions must be handled under standard test conditions (see index) as far as may be; in accepting the observations of others one must be sure that they are sufficiently trained and sufficiently careful and veracious to render their statements reliable. In order to introduce the subject to the literature of the profession and to invite comment and discussion looking toward the ultimate development of a complete Chiropractic prognosis we shall set down, without further preliminary, the general prognosis of those commonly described diseases concerning which we feel qualified to speak. No statement is made without the gathering of reliable evidence. GENERAL PROGNOSIS =Abscesses.=--Those abscesses which would tend to discharge externally may be adjusted for with success and will rapidly develop, point, and discharge, with quick recovery. Those which might break internally absolutely forbid adjustment because of the almost certain occurrence of peritonitis, pyaemia, or other grave condition. =Acne.=--Good, but usually slow. =Addison’s Disease.=--Few cases reported, and these slow cures. =Adenoids of Pharynx.=--Prognosis so good as to contraindicate operation in every case. The lymphoid growths gradually and slowly absorb under adjustment. =Adiposis Dolorosa.=--Only one case seen, the Derkum case. This reduced in six months of adjustment from 360 to 280 lbs. in weight, and was improved in every particular. No final report received. =Alcoholism.=--Adjustments greatly aid a cure if alcohol be discontinued at once, or if the daily consumption is gradually and steadily decreased. No permanent cure can be secured without the aid of the patient. Acute alcoholic intoxication may be lessened at once by the aid of a single adjustment. =Amenorrhoea.=--Prognosis excellent. One to several months required. Conservative amenorrhoea, as in tuberculosis or other wasting disease, disappears only with the occasion.
