Night-Terrors.--Cases under this heading form a distinct group by themselves. They are not frequent, but the condition is much more serious. The cause seems to be wholly nervous and may indicate an important nervous derangement. It seems to have some indefinite relation to such conditions as migraine, hysteria, epilepsy, and even insanity. The child wakes suddenly during the night and sits up, evidently in terror; he does not apparently regain his full consciousness. He talks of being scared, calls for his mother, trembles and shakes, cannot answer questions intelligently, and after a time goes to sleep. Next day he remembers nothing of the attack and does not seem to suffer in any way as a result of it. I am disposed to believe that all of these attacks are not due to a nervous condition. A number of them of exactly this type have been cured by absolutely withdrawing milk from the diet. It is a good plan to restrict the possibility of excessive play in these children. They are of the type whose play is work, and too much of it is too exhausting. Some person should sleep in the same room with these patients or in an adjoining room with the door open. If the condition occurs frequently the child should be subjected to a thorough physical examination, because it may be one evidence of a serious ailment. Sometimes these little patients have to be taken out of school and sent to the country, where they should remain for many months. It is far better to regard the condition as indicating an abnormality,--even though it may not have any deeper significance than that the digestive apparatus of the child is not quite right,--and make every effort to cure it, than to permit the child to go on under what really are unjust and unfavorable conditions. HEADACHE Headaches are not common in little children. The most frequent ones are caused by: 1. Chronic indigestion and constipation. 2. Anemia and malnutrition. 3. Nervous disorders. 4. Diseases of the eye, nose, throat. 5. Rheumatism and gout. 6. Disturbances of the genital tract. Those arising from anemia and poor nutrition are most frequently present in girls from ten to fifteen years of age. They may result from overcrowding of school work, which results in loss of appetite and poor sleep. Nervous headaches may be hereditary or acquired through unhygienic surroundings. Hysteria, epilepsy, disease of the brain, neuralgia from carious teeth, may result in nervous headaches. Headaches from disturbances of the genital tract may afflict girls about the time of puberty. Treatment.--To remove the cause is the only plan that promises any result. Each one must be investigated by itself and dealt with accordingly. For the headache itself a hot foot bath, cold to the head, and small doses of phenacetine (one grain every hour for four doses) are perhaps the most certain of all methods of treatment. THUMB-SUCKING
