Clinical diagnosis and alternative causes & Acute relief versus prevention

Clinical diagnosis and alternative causes

Diagnosis usually relies on headache pattern, associated symptoms, history, and physical and neurological examination. No single test proves every headache is migraine. Typical cases may not need specialized testing, while new or unusual neurological findings can justify imaging or other investigations. Weakness or changes in alertness matter during assessment. Testing often investigates another possible cause rather than directly confirming migraine with one definitive laboratory measurement.

Acute relief versus prevention

Acute treatment addresses an ongoing attack; preventive treatment aims to reduce future frequency. Regular sleep, consistent meals, and stress management can support prevention. A diary helps connect attacks with possible triggers and review patterns. Frequent pain-reliever use can itself contribute to rebound headaches. Repeated headaches are therefore not always a reason to increase pain medicine independently; care considers both the migraine pattern and the medicine-use pattern.

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.
