Migraine

Key Points

• Migraine attacks are recurrent, often unilateral, throbbing headaches that can last 4 to 72 hours when untreated.
• Associated symptoms include nausea, vomiting, photophobia, and phonophobia.
• Classic migraine includes aura; common migraine occurs without aura.
• There is no cure, so management focuses on trigger avoidance plus acute and preventive therapy.
• Lifestyle optimization, medication strategy, and stress-response training are core care domains.

Pathophysiology

Migraine is linked to abnormal brain activity involving nerve pathways and neurochemical changes that influence cerebral and pericranial blood-flow dynamics. Exact mechanisms remain incompletely defined, and attacks are often precipitated by identifiable personal triggers.

Classification

• Classic migraine (with aura): Neurologic warning symptoms precede headache, such as visual disturbances.
• Common migraine (without aura): Migraine phenotype without prodromal neurologic aura pattern.

Nursing Assessment

NCLEX Focus

Differentiate aura findings, trigger history, and attack pattern to individualize prevention and rapid self-management.

• Assess headache pattern, duration, intensity, and associated nausea/vomiting or light/sound sensitivity.
• Assess aura features such as blind spots, flashing lights, zigzag lines, blurred vision, eye pain, or tunnel vision.
• Assess trigger profile: sleep disruption, missed meals, caffeine withdrawal, stress, hormonal shifts, alcohol, sensory overstimulation, smoke exposure, and food triggers (for example tyramine/MSG-containing foods).
• Assess postdrome effects such as fatigue or confusion after attacks.
• Assess family history and functional impact on daily life.
• Screen for secondary-headache red flags (sudden worst headache, neck stiffness, seizure/confusion/LOC change, trauma-related onset, or new persistent headache in a previously headache-free patient) and escalate urgently when present.

Nursing Interventions

• Teach trigger-avoidance planning and symptom diary use.
• Reinforce lifestyle protection: regular sleep schedule, meal regularity, stress control, and weight optimization when indicated.
• Teach early-attack self-care: rest in dark quiet room, cool compress, hydration, and early symptom-directed medication use.
• Support escalation pathways for frequent attacks or functional decline requiring preventive therapy adjustment.
• Integrate biofeedback and relaxation training for stress-modulation support.

High-Frequency Attack Burden

Frequent migraine attacks can significantly impair function and may require preventive regimen reassessment.

Pharmacology

Drug Class	Examples	Key Nursing Considerations
Acute analgesic therapy	Ibuprofen, aspirin, acetaminophen; combination products with caffeine	Use early in attack for mild-moderate pain; monitor overuse risk.
Migraine-specific acute therapy	Ergot derivatives, triptans	Most effective early in attack; selected based on severity and risk profile.
Preventive therapy	Anticonvulsants, beta-blockers/calcium-channel blockers, antidepressants, CGRP agents, onabotulinumtoxinA	Daily prevention for frequent/severe migraine burden and functional impairment.
Adjunctive supplements	Riboflavin, magnesium	Can be used in prevention plans for selected patients.

Clinical Judgment Application

Clinical Scenario

A patient reports recurrent unilateral pulsating headaches with visual zigzags, nausea, and work absences despite intermittent OTC use.

• Recognize Cues: Classic migraine pattern with significant functional burden.
• Analyze Cues: Trigger control and medication strategy are insufficient.
• Prioritize Hypotheses: Reduce attack frequency and improve function with preventive optimization.
• Generate Solutions: Build trigger-management plan and reassess acute versus preventive medication balance.
• Take Action: Implement structured lifestyle and pharmacologic plan with follow-up.
• Evaluate Outcomes: Attack frequency, severity, and activity limitation decrease over time.

• beta-blockers - Common preventive-option class for migraine prophylaxis.
• anticonvulsants - Preventive options that reduce neuronal excitability.
• antiemetics - Adjunctive nausea and vomiting management during attacks.
• seizures-and-epilepsy - Aura terminology overlap requires differential clarification.
