Methamphetamine inhalation frequently causes hemorrhagic stroke, even in young adults. This drug use is as likely to cause intracerebral hemorrhage as brain infarction.

Area of Science:

  • Neurology
  • Toxicology
  • Public Health

Background:

  • Methamphetamine abuse is a growing public health concern.
  • Stroke is a known complication of methamphetamine use, but the specific type of stroke is debated.
  • Understanding the relationship between methamphetamine and stroke is crucial for clinical management and prevention.

Purpose of the Study:

  • To investigate the characteristics of stroke events in patients following methamphetamine inhalation.
  • To compare the incidence of hemorrhagic versus ischemic stroke in this population.
  • To identify potential stroke risk factors associated with methamphetamine use.

Main Methods:

  • Retrospective case series of seven patients admitted with stroke within 3 days of methamphetamine inhalation.

  • Clinical data collection including demographics, medical history, and stroke risk factors.
  • Neuroimaging including computed tomography (CT) and angiography to evaluate stroke type and vascular abnormalities.

    • Main Results:

    • Five out of seven patients experienced hemorrhagic stroke (intracerebral hemorrhage), while two had ischemic stroke.
    • Hemorrhagic strokes occurred in various brain regions (lobar, caudate, putaminal).
    • Ischemic strokes were located in the middle cerebral artery (MCA) territory. Most patients were young and had multiple stroke risk factors, including hypertension in three.
    • Angiography revealed vasculopathy or vasospasm in only one patient with arteriovenous malformation.

    Conclusions:

    • Methamphetamine inhalation is a significant cause of stroke in young adults.
    • Intracerebral hemorrhage is as common, if not more common, than ischemic stroke following methamphetamine inhalation.
    • The findings challenge previous assumptions about the predominant stroke type associated with methamphetamine use.
