Headache

Cluster headaches

Cluster headaches are a series of relatively short but extremely painful headaches every day for weeks or months at a time. You tend to get them at the same time each year, such as the spring or fall. Because of their seasonal nature, people often mistake cluster headaches for symptoms of allergies or business stress.

Migraine

Migraine is a complex disorder characterized by recurrent episodes of headache, most often unilateral and in some cases associated with visual or sensory symptoms-collectively known as an aura-that arise most often before the head pain but that may occur during or afterward (see the image below). Migraine is most common in women and has a strong genetic component.

Tension-type headache (TTH)

Tension-type headache (TTH) category, further defined as either episodic or chronic.

Trigeminal neuralgia (TN)

Trigeminal neuralgia (TN) also known as tic douloureux, is a distinctive facial pain syndrome that may become recurrent and chronic. It is characterized by unilateral pain following the sensory distribution of cranial nerve V (typically radiating to the maxillary or mandibular area in 35% of affected patients) and is often accompanied by a brief facial spasm or tic.
