What Is the Preventive Treatment of Hemiplegic Migraine?

Hemiplegic migraine is a rare subtype of migraine with aura in which attacks include transient motor weakness or hemiplegia. Both sporadic and familial forms require a structured preventive approach to reduce attack burden.

Treatment Goal

The primary target is a reduction in migraine attack frequency of 50% or more, assessed after the patient has been maintained at the highest tolerated dose for approximately two months.

Prevention Approach

Preventive therapy for hemiplegic migraine includes specific agents that have shown efficacy in both sporadic and familial presentations — including options used as monotherapy and certain combination strategies. The complete protocol, agent selection criteria, and sequencing are detailed in the full regimen.

In hemiplegic migraine, lamotrigine or acetazolamide can be used.
An effect of acetazolamide or lamotrigine, also in combination with valproic acid, has been described for sporadic or familiar hemiplegic migraine.
Migraine prevention is considered effective when it achieves a reduction of the migraine attack frequency of 50% or more.
The effectiveness, defined as a reduction of migraine days by 50%, can be evaluated 2 months after reaching the highest tolerated dose.
