Cluster headaches are often misunderstood and are not the same as migraines.
March 21 is International Cluster Headache Awareness Day.
Cluster headache is a neurological condition characterized by recurring headache attacks that often follow daily and seasonal rhythms. Many individuals experience symptom changes during seasonal transitions such as spring and autumn.
Because cluster headaches differ from migraines and other headache disorders, accurate evaluation plays an important role in understanding symptoms and guiding care.
The Concussion & Migraine Clinic (CMC) provides specialized evaluation and care for individuals experiencing complex headache conditions.
