migraine
a migraine is a neurological condition that can cause multiple symptoms. it's often characterized by intense, debilitating headaches. symptoms may include nausea, vomiting, difficulty speaking, numbness or tingling, and sensitivity to light and sound. migraines often run in families and affect all ages.
the cause of migraines is not completely understood, but they're thought to be the result of abnormal brain activity temporarily affecting nerve signals, chemicals, and blood vessels in the brain.
migraine attacks can last for hours to days, and the pain can be so severe that it interferes with daily activities. some people have migraines frequently, up to several times a week. others may only experience a migraine occasionally.
triggers for migraines can vary widely and may include hormonal changes, stress, loud noises, strong smells, certain foods or additives, sleep disturbances, and medications.
diagnosis of migraines involves a medical history and a physical and neurological examination. there are no specific tests to diagnose migraines, but tests can be done to rule out other causes of the symptoms.
treatment is aimed at preventing a full-blown attack and alleviating symptoms if they come. this can include pain relief medications and preventive medications to reduce the frequency and severity of the migraines.
