The cerebral ischemic cascade.

W K Hass

    Neurologic Clinics
    |February 1, 1983
    PubMed
    Summary
    This summary is machine-generated.

    Brain ischemia triggers a cascade of biochemical events. Lactic acidosis accelerates this process, while calcium influx into neurons causes cell death.

    Area of Science:

    • Neuroscience
    • Biochemistry
    • Pathophysiology

    Background:

    • Brain ischemic insults initiate a series of detrimental biochemical reactions.
    • Understanding these events is crucial for developing neuroprotective strategies.

    Purpose of the Study:

    • To review the key biochemical alterations following brain ischemia.
    • To highlight the roles of lactic acidosis and calcium in neuronal death.

    Main Methods:

    • Literature review of biochemical events in ischemic brain injury.
    • Analysis of evidence implicating lactic acidosis and calcium.

    Main Results:

    • Lactic acidosis significantly accelerates the ischemic cascade.
    • Uncontrolled calcium entry into neurons is a key trigger for cell death.

    Conclusions:

    • Lactic acidosis is a critical factor exacerbating ischemic brain damage.
    • Targeting calcium influx may offer a therapeutic approach to prevent neuronal death after stroke.
