Heavy marijuana use may cause cerebellar infarcts in adolescents. Researchers suspect hypotension and impaired reflexes during marijuana intoxication led to the stroke.

Area of Science:

  • Neurology
  • Vascular Neurology
  • Pediatric Neurology

Background:

  • Cerebrovascular events are rare in adolescents.
  • Marijuana use is increasing among adolescents.
  • The link between marijuana use and stroke is not well understood.

Observation:

  • A 15-year-old experienced a cerebellar infarct affecting multiple arterial territories.
  • The infarct occurred in temporal relation to heavy marijuana use.

Findings:

  • Heavy marijuana use is the suspected cause of the cerebellar infarct.
  • Potential mechanisms include marijuana-induced hypotension and impaired vasomotor reflexes.
  • The patient may have had compromised cerebral autoregulation, predisposing them to stroke during hypotensive episodes.

Implications:

  • This case highlights a potential risk of marijuana use in adolescent cerebrovascular health.
  • Further research is needed to elucidate the mechanisms of marijuana-associated stroke.
  • Clinicians should consider marijuana use in the differential diagnosis of stroke in young patients.
