This is a neurological disorder that usually begins near middle age and is more common in women than in men. It tends to occur in older individuals or those around the age of fifty. After the age of fifty, this disease generally subsides.
This condition is closely related to menopause, as it is not observed in women after menopause. In this disease, severe pain occurs on one side of the head, sometimes on the right or left, and occasionally all over the head. In the case of pain throughout the head, the sensation of pain on one side is relatively more intense. Nausea and extreme sensitivity to light and sound accompany the pain. The intensity of the pain starts to increase with the rising sun and decreases with the setting sun. The pain usually subsides with the sunset, and the patient feels completely healthy upon awakening.
