Migraine Types

Migraine Without Aura — The most common form of migraine, without a preceding aura phase.

Migraine With Aura — Migraine preceded or accompanied by reversible neurological symptoms such as visual disturbances.

Chronic Migraine — Headache on 15+ days per month for 3+ months, with at least 8 meeting migraine criteria.

Episodic Migraine — Migraine occurring on fewer than 15 days per month, the more common pattern outside chronic migraine.

Vestibular Migraine — Migraine involving vertigo and dizziness as a primary symptom.

Hemiplegic Migraine — A rare migraine with aura involving temporary one-sided motor weakness that can mimic stroke.

Menstrual Migraine — Migraine tied to the drop in estrogen before menstruation.

Abdominal Migraine — A migraine variant causing recurrent abdominal pain, most common in children.

Status Migrainosus — A debilitating migraine attack lasting longer than 72 hours.

Silent Migraine — Migraine aura occurring without a subsequent headache.

Ocular Migraine — A popular but informal term usually referring to visual aura, sometimes to retinal migraine.

Retinal Migraine — A rare condition causing vision loss confined to one eye.

Cyclic Vomiting Syndrome — Recurrent severe vomiting episodes classified within the migraine spectrum, most common in children.

Benign Paroxysmal Vertigo of Childhood — Brief episodes of vertigo in young children, an early childhood migraine syndrome.

Migrainous Infarction — A rare complication where prolonged aura corresponds to an actual stroke on imaging.

Migraine With Brainstem Aura — A rare migraine type formerly called basilar migraine.

Additional Recognized Terms

High-Frequency Episodic Migraine — Episodic migraine occurring on 10-14 days per month.

Low-Frequency Episodic Migraine — Episodic migraine occurring on fewer than 10 days per month.

Benign Paroxysmal Torticollis — A rare infant condition involving episodes of head tilting, considered a childhood migraine precursor.

Persistent Aura Without Infarction — Aura symptoms lasting beyond one week without evidence of stroke on imaging.

Migralepsy — A rare, debated entity in which a seizure occurs during or shortly after a migraine aura.

Probable Migraine — Attacks that meet all but one diagnostic criterion for migraine.

Ophthalmoplegic Migraine — An older term for a condition now reclassified as Recurrent Painful Ophthalmoplegic Neuropathy.

Transformed Migraine — An older term for what is now classified as chronic migraine.

HPA axis (hypothalamic-pituitary-adrenal axis) — The body's primary stress-response system, involving communication between the hypothalamus, pituitary gland, and adrenal glands. Chronic activation of this system — from stress, anxiety, or other triggers — increases cortisol output and is linked to lowering the threshold for migraine attacks.
