The power-of-will is also affected and the stammerer notes an inability to put through the things which he starts and which require the exercise of will power to bring to a successful conclusion.

A diagnosis of insanity is sometimes made in the case of a stammerer in the advanced stages of his malady, while in other instances the mental aberration takes the form of a hallucination of some sort, as in the case of the boy who was of the belief that he was continually being followed.

But regardless of what form is taken by the mental disorder resulting from stammering, such cases are almost invariably found to have long since passed into the incurable stage, although positive statements as to the individual's condition should not be made, as a rule, without a thorough diagnosis having first been made.

CHAPTER VIII

THE EFFECTS ON THE BODY

The effect of stammering or stuttering upon the physical structure is problematical. In some cases examined, a noticeable lack of vitality has been found, together with an almost total loss of active appetite, a marked inclination toward insomnia and a generally debilitated condition resulting from the nervous strain and continued fear brought on by the speech disorder.

In other cases, it has been found that the health was but little affected and that there was no marked departure from normal.

The physical condition of the stammerer is the result of many factors. If plenty of fresh air and exercise is supplied, and the mind is well-employed so that the worry over the trouble does not disturb the stammerer, then the chances for being in a normal physical condition are good.

On the other hand, the boy of studious disposition, who is somewhat of a bookworm, keeps close to the house and does not play with other children of his age, will probably find time for much introspection, and on this account, as well as on account of the lack of fresh air and exercise, will probably be in a physical condition that of itself demands careful attention.
