Fever after ischemic stroke worsens brain damage and outcomes. Promptly treating fever with medication is crucial for improving stroke recovery, as cooling therapies lack proven benefits.

Area of Science:

  • Neurology
  • Pathophysiology
  • Biochemistry

Background:

  • Hyperthermia is a common complication following ischemic stroke.
  • The exact pathophysiology and clinical significance of post-stroke hyperthermia are not fully understood.
  • Hyperthermia can be triggered by the brain infarct itself or associated biochemical and inflammatory processes.

Purpose of the Study:

  • To elucidate the role of hyperthermia in ischemic stroke progression.
  • To highlight the detrimental effects of elevated body temperature on brain injury and stroke outcomes.
  • To review current recommendations for managing post-stroke hyperthermia.

Main Methods:

  • Review of clinical and experimental studies on hyperthermia and ischemic stroke.
  • Analysis of the mechanisms by which hyperthermia exacerbates ischemic brain damage.

  • Evaluation of the impact of body temperature on stroke outcome within the first 24 hours.

    • Main Results:

    • Hyperthermia accentuates ischemic mechanisms in the penumbra, converting reversible damage to irreversible lesions.
    • Clinical and experimental data confirm that hyperthermia worsens ischemic brain damage and stroke outcomes.
    • Increased body temperature within 24 hours of stroke onset is particularly detrimental.

    Conclusions:

    • Hyperthermia following ischemic stroke is both induced by and contributes to infarct progression.
    • Pharmacological treatment of hyperthermia is recommended for all ischemic stroke patients to improve outcomes.
    • Further research into hyperthermia mechanisms may reveal new therapeutic strategies, but current evidence does not support routine cooling therapy.
