Learning objectives
- Explain brain activity and individual triggers.
- Explain aura and recovery beyond the headache.
Brain activity and individual triggers
Migraine involves abnormal brain activity, nerve pathways, and chemical signaling, although the exact sequence remains uncertain. Throbbing pain, often on one side, can occur with nausea and sensitivity to light or sound. Family history contributes to susceptibility. Missed meals, disrupted sleep, stress, alcohol, hormonal changes, or strong smells may trigger attacks. A trigger starts an episode in some people; it is not a complete explanation of the disorder.
Aura and recovery beyond the headache
Aura involves temporary neurological symptoms, commonly visual changes such as flashing lights, zigzag lines, or blind spots. Not every migraine has aura, and aura does not always lead to headache. Pain can intensify over minutes or hours and last for hours to days. Fatigue, neck discomfort, or unclear thinking may persist afterward. An attack can therefore affect daily functioning beyond the period when headache itself is most noticeable.
Key concepts
- Brain activity and individual triggers
- Migraine involves abnormal brain activity, nerve pathways, and chemical signaling, although the exact sequence remains uncertain.
- Aura and recovery beyond the headache
- Aura involves temporary neurological symptoms, commonly visual changes such as flashing lights, zigzag lines, or blind spots.
- Clinical diagnosis and alternative causes
- Diagnosis usually relies on headache pattern, associated symptoms, history, and physical and neurological examination.
- Acute relief versus prevention
- Acute treatment addresses an ongoing attack; preventive treatment aims to reduce future frequency.
