A headache is a warning signal
The headache is a very common malaise which is a challenge not only to neuro psychiatrist, but also to emergency doctors in their daily routines. Epidemic statistics have shown that as many as 90% of the male world and 95% of the female world have had headache in the last year. Throughout one’s life time one would occasionally have a headache.
In fact a headache is but a symptom which can be traced to a lot of causes, severity of a headache also varies vastly. In most cases a headache is benign, only in rare cases would a headache endanger the life, and must be treated immediately. A benign case, although not lethal, can have negative effects on the living quality. For all that reasoning, a headache case deserves correct diagnosis, reliance on the intake of ready made analgesic or shooting serves to little more than just transient relief.

Migraine
Migraine can occur at any age, but mostly in the adolescent phase, the first fit mostly comes before age 40. With the female world migraine strikes 3 to 4 times more often than it does on the male population, about 70~90% of the patients have a family tradition in this connection. A typical migraine hits one-sidedly, of a moderate to grave severity, and the headache will turn worse as day-to-day activities are carried out, accompanied with nausea, photophobia and noise nervosity, each fit will last 4~72 hours. Several hours or 1 or 2 day prior to the onset of a migraine premonitory signs may show up, and be seen in increased or decreased activities, depression, becoming addicted to some kind of food, repeated yawning. To which the incentives include: pressure, oversleeping, hunger, tiresomeness and certain medicines, chocolate, cheese even alcohol and miso can induce a migraine.
To treat a migraine case, the first priority is to avoid incentive origins and non-drug treatments, before drug prescription is administered. Drug is not only good for an acute phase, but is just as good for preventive purposes.

Apoplexy and headache
Statistics have shown the incidence rates of all apoplexia cases categorically as follows: cerebral hemorrhage: 57%, anemic apoplexy: 34%; transitory deficiency of blood in the brain: 29% as owning to or accompanied with a headache. Clinically cerebral hemorrhage or anemic apoplexy is indicated by localized central neurosis, as to which there is no difficulty for diagnosis. There is, however, one specific genre of apoplexy that deserves special attention, “sub-arachnoidal hemorrhage”. Clinically it manifests itself in sudden, intransigent headache accompanied with neck stupor, photophobia, noise nervosity, vomiting and even coma, by virtue of which patients aged above 40 are mostly initiated by a ruptured arterial tumor in the brain, which must be diagnosed as soon as possible and once correctly diagnosed, be treated by surgical operation.
