Intermittent oscillopsia and nystagmus in a migraine patient resolved with treatment. This suggests a link between migraine-related brainstem ischemia and dormant nystagmus.

Area of Science:

  • Neuroscience
  • Ophthalmology

Background:

  • Migraine headaches can be associated with neurological symptoms.
  • Brainstem ischemia is a potential complication of migraines.

Observation:

  • A 38-year-old woman experienced recurrent, brief episodes of oscillopsia (visual disturbance) and right-beating jerk nystagmus.
  • These symptoms occurred periodically and resolved spontaneously.
  • Neurological examinations were normal between episodes, with no nystagmus detected.

Findings:

  • The patient's oscillopsia and nystagmus resolved completely when her migraine headaches were medically managed.
  • This intermittent nystagmus pattern may indicate a dormant form of periodic alternating nystagmus or other intermittent nystagmus.

Implications:

  • Episodic migrainous brainstem ischemia could be the underlying cause of this intermittent nystagmus.
  • This case highlights a potential, previously unrecognized, manifestation of migraine-related neurological dysfunction.
  • Further research is warranted to explore the relationship between migraine, brainstem ischemia, and intermittent nystagmus.
