People who have a genetic predisposition to migraine have a ninety percent chance of passing the condition on to their children. In fact, a person with one parent with migraines has a fifty percent chance of developing the disorder. Although there are no definitive causes for the development of migraine, it is suspected that the symptoms are triggered by changes in brain activity that affect the nervous system. The symptoms of a migraine vary from person to person, but there are several factors that can trigger them.

The prodrome phase is the period leading up to the attack and is the most difficult to treat. Symptoms of a migraine can last anywhere from four to 72 hours. It usually begins with an aura, or a warning symptom that occurs up to 24 hours before the headache. Symptoms of an aura can include a pulsing sensation, vision problems, and nausea. Affected people often experience a sensitivity to light, sound, and pain, which can interfere with everyday activities and even social interactions.

Certain medications can cause migraines, as can exposure to fluorescent and flashing lights. Experiencing strong odors such as smoke can also trigger migraines. As migraines can start in the morning, it’s essential to rest for at least three hours and avoid exposure to bright sunlight or perfumes. If you’re experiencing a regular bout of migraine, it’s important to note the times when you sleep, the duration of the attack, when the prodrome begins, and how much stress you’re feeling.

There are many possible migraine causes, but classic migraines are the most common. These include an aura (warning signs) that appears during the first few minutes of a headache and a sudden loss of side vision. The pain is often so intense that the sufferer may have difficulty communicating, as well as a depressed mood. A complex migraine is difficult to treat, but if the headache continues, it’s important to seek medical attention.

The trigeminal nerve gives sensation to the face and head. In migraines, overactive nerve cells release neurotransmitters, which are chemicals that cause pain. Serotonin triggers the production of CGRP, which makes blood vessels in the brain lining swell. Unlike a typical migraine, a chronic migraine is a constant, unrelenting headache. If the symptoms are persistent and frequent, you may have to go to a doctor frequently.

Some environmental factors can also trigger migraines. Acute migraines occur when your body reacts to certain smells, colors, or sounds. If you’re experiencing a migraine, avoiding such triggers could help prevent the onset of the condition. If you’re concerned about the symptoms of your headache, you can consult a health care provider and make changes to your lifestyle. If you have an ongoing migraine, you should seek treatment immediately to avoid complications.
