Summary

Vertebral artery dissection can cause acute amnesia, affecting both memory formation and recall. These memory deficits fully resolved in two patients with conservative treatment.

Area of Science:

  • Neurology
  • Vascular Neurology
  • Neuroscience

Background:

  • Vertebral artery dissection (VAD) is a rare condition often associated with posterior circulation stroke.
  • Amnesia is not a commonly recognized symptom of VAD.

Observation:

  • Two male patients presented with sudden, severe anterograde and partial retrograde amnesia.
  • Both patients were diagnosed with spontaneous vertebral artery dissection.

Findings:

  • The amnesic syndrome in both cases was directly attributed to vertebral artery dissection.
  • Complete resolution of amnesia was achieved with conservative management strategies.

Implications:

  • This case series suggests a potential link between VAD and acute transient amnesia.

Related Experiment Videos

  • Clinicians should consider VAD in the differential diagnosis of acute amnesia, even without typical stroke symptoms.
  • Further research is warranted to understand the pathophysiology and prevalence of amnesia in VAD.
