About MIGRAINES

.
A migraine is a chronic condition that is characterized by a recurrent headache, of moderate to severe intensity, often associated with a series of symptoms of the autonomic nervous system. The term comes from Greek from hemicrania ("hemicrania"), "pain in one side of the head", from hemi- "," half "and" kranion "," skull ".

Typically, migraines are unilateral (affecting only half the head) and are pulsed, with a duration of between 2 and 72 hours. Symptoms can include nausea, vomiting, photophobia (light hypersensitivity), phonophobia (excessive hearing sensitivity), pain is generally aggravated by physical activity. Up to one-third of patients experience aura: a transitory disorder of visual, sensory, linguistic or motoric nature, which signals that headache will soon be established.

Migraines are thought to be due to a mixture of genetic and environmental factors. Approximately two-thirds of cases are determined by hereditary predispositions. Hormonal fluctuations may also play a role: a migraine affects a slightly higher number of boys than girls before puberty, but in the case of adults it is two to three times more frequent in women than in males. Typically, the trend of a migraine decreases during pregnancy. Migraine mechanisms are not exactly known. However, migraine is considered a neurovascular disease. [5] Primary theory refers to an increased sensitivity of cerebral cortex and abnormal control of pain neurons in the trigeminal nucleus of the cerebral cortex.

In the initial treatment of a migraine, simple analgesics such as ibuprofen and paracetamol against a headache, antiemetics against vomiting and avoiding trigger factors are recommended. If simple analgesics are not effective, specific agents such as triptans or ergotamines may be prescribed. Over 10% of the global population suffers from a migraine at some point in their lifetime.
