Differentiating Hemiplegic Migraine from Stroke

Key Differences

• Hemiplegic Migraine:

  • Symptoms develop gradually.
  • Aura symptoms precede other symptoms.
  • Sequence of symptom development:
    1. Visual symptoms
    2. Sensory symptoms (e.g., tingling, numbness)
    3. Language problems
  • Symptoms appear in a sequence rather than all at once.

• Stroke:

  • Symptoms occur suddenly and simultaneously.
  • There is no sequential progression like in hemiplegic migraine.

Detailed Analysis

• Hemiplegic Migraine Characteristics:

  • Patients often experience visual illusions or sensory symptoms first.
  • The progression is typically: visual → motor (weakness) → sensory.
  • Important to note the gradual onset and spread of symptoms.

• Stroke Characteristics:

  • All symptoms, including visual and motor, occur at once.
  • Immediate medical attention required due to the sudden onset.

• Quick recognition and appropriate response can significantly impact patient outcomes.
