An eight-year-old girl, previously in good health, and with no more nervousness than is displayed by the average child, began to show traits that worried her parents. She became difficult to control, querulous, and sullen to an extent that bordered on melancholia. In addition, she complained of indigestion and headache, symptoms which caused her parents to take her to a physician for treatment. His medicines and the course of diet he prescribed did her no good, and another physician was consulted. Then began for this unfortunate little girl a weary round of examinations by doctor after doctor. Every means of curing her headaches and indigestion seemed unavailing, and her nervousness and sullenness increased apace. Finally, one physician, in spite of the fact that the girl's eyesight seemed normal, suggested that she be examined by an eye specialist. Then, for the first time, it was discovered that she had a serious ocular defect. According to Doctor Percy R. Wood, who reported the case for the benefit of the medical profession in general, within six months after she first put on spectacles the girl was entirely free from digestive disturbances, her head had ceased to ache, and her melancholy moroseness had given way to normal good nature. Occasionally sulkiness results from some special form of nervous disease. It may be an initial symptom of that strange malady of childhood, chorea. A child affected with chorea is restless, uneasy, and weak in muscular control. Muscles of the face twitch, the child has difficulty in using his hands, and, in later stages of the disease, the arms and legs make random, involuntary movements. In addition, just before or about the time the muscular weakness begins, there are sometimes signs of mental disturbance, described as follows by an authority on nervous diseases: "These symptoms consist of a slight loss of memory and inability of the patients to apply themselves to their studies as well and continuously as formerly. Children who were previously of an obedient and mild disposition become irritable, obstinate, and perverse. They become insubordinate, lose their love of play, and are not as affectionate as was their wont. These phenomena are naturally looked upon as indubitable evidences of wilfulness, and are punished accordingly, thus frequently precipitating and aggravating the course of the disease."
