What Is Episodic Migraine?
Episodic migraine is a neurological condition characterized by recurrent headache attacks that occur on fewer than 15 days per month. These episodes can cause moderate to severe pain, often accompanied by nausea, sensitivity to light or sound, and visual disturbances known as aura.
While less frequent than chronic migraine, episodic migraine still has a major impact on quality of life — affecting work, social activities, and emotional well-being. According to the American Headache Society, episodic migraine affects over 30 million people in the United States.

Symptoms of Episodic Migraine
Episodic migraines typically last 4 to 72 hours per episode and may include:
- Moderate to severe throbbing or pulsating head pain
- Pain that worsens with physical activity
- Nausea or vomiting
- Sensitivity to light, sound, or smell
- Visual aura (flashes, zigzag lines, or blind spots)
- Fatigue, dizziness, or neck pain before or after attacks
Some individuals also experience prodrome symptoms — such as mood changes, food cravings, or yawning — hours before a migraine begins.
