Migraine is an episodic headache, typically unilateral, often associated with nausea, vomiting, visual disturbance and dizziness.
- Migraine is the most common neurological condition and affects 8-14 per cent of people in the developed world.
- Migraines may be caused by an underlying central nervous system disorder that affects the brain’s vascular system. Stress or some unknown factor triggers the release of peptides, which dilate blood vessels and causes over-excitation of nerves in the trigeminal pathway.
- Migraines progress through five phases, each with its own distinct symptoms (Blau, 1987). Not every person experiences all phases: up to 70 per cent of people do not experience auras.
- A high dose non-steroidal anti-inflammatory drug together with an antiemetic can prevent a migraine attack. The earlier the medication is taken the more effective it will be.
- Advise patients to identify and avoid their own trigger factors.
