Migraine Q & A

What primary headaches most often affect adults?

There are many different types of headaches, but they’re all categorized as primary or secondary. Primary headaches are caused by problems in your head and neck, while secondary headaches develop due to an underlying health problem. The most common primary headaches are tension headaches, cluster headaches, and migraines.

What causes migraines?

Migraines are neurological disorders that develop when cranial nerves overreact to a trigger and activate the release of biochemicals in your brain. The result of this reaction is an intense migraine headache, along with its associated bodywide symptoms.

Migraine triggers are different for each patient, but these are a few of the most common:

  • Stress
  • Fatigue
  • Caffeine
  • Strong odors
  • Bright lights
  • Skipping a meal
  • Changes in weather
  • Certain foods and additives

One of the first steps in treating a migraine is to identify your triggers so you can avoid them.

What stages occur during a migraine headache?

Migraine headaches may progress through four distinct stages. Everyone experiences the migraine attack; you may or may not go through the other stages:


Many patients notice subtle changes, such as mood swings, food cravings, and excessive thirst, a day or two before their migraine begins.


About one-third of migraine patients experience aura, which starts about 30 minutes before the headache. Aura frequently involves vision changes, such as seeing wavy lines or flashes of light. You may also experience sensations such as hearing noises, muscle weakness, and difficulty speaking.


This is the stage when your migraine begins. Migraines cause severe, throbbing pain that’s often around one temple but may involve both sides of your head. You’ll also experience bodywide symptoms such as nausea, vomiting, vertigo (the sensation of spinning), and sensitivity to light, smells, sounds, and touch. Migraine attacks last 4-72 hours.


Some patients experience dizziness, confusion, weakness, and ongoing sensory sensitivity for up to 24 hours after their migraine pain ends.

What treatment might I receive for migraines?

Dr. Mehta may prescribe medications that you take at the first sign of a migraine attack to reduce its severity. You may also benefit from taking a daily medication that helps prevent future migraines, reducing their frequency, length, and severity. 

If you have chronic migraines, Dr. Mehta may recommend Botox® injections. Chronic migraines are defined as having 15 or more migraines a month, with each one lasting at least four hours. Botox is a preventive treatment that helps reduce migraine frequency.
