Summary

Exertion can trigger migraine aura, including hemiparetic attacks. This case suggests migraine aura is a key consideration for exertion-induced neurological deficits.

Area of Science:

  • Neurology
  • Neuroscience

Background:

  • Exertion is a known migraine headache aggravator.
  • The link between physical exertion and migraine aura remains unclear.

Observation:

  • A 67-year-old man experienced recurrent hemiparetic attacks triggered by exertion.
  • Initial diagnosis considered transient ischemic attacks, but clinical presentation, normal neuroimaging, and lack of response to vascular treatments suggested otherwise.
  • Successful treatment with verapamil further supported a migraine aura etiology.

Findings:

  • The case suggests exertion can precipitate migraine aura, potentially by lowering the threshold for cortical spreading depression.
  • Hemiplegic migraine aura, even without a family history, may be linked to genetic factors like ion channel gene mutations.

Implications:

  • Migraine aura should be considered in the differential diagnosis of focal neurological deficits induced by exertion.
  • This highlights the importance of considering migraine aura in patients presenting with exertion-related neurological symptoms.
