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.
