This tissue is at risk but salvageable, representing a critical therapeutic window where intervention can prevent permanent disability. Excitotoxicity and the Glutamate Storm With ATP depleted, glutamate, the primary excitatory neurotransmitter, is not efficiently cleared from the synaptic cleft.
NMDA Receptor Blockade in the Ischemic Cascade
Processes such as blood-brain barrier breakdown, cerebral edema, and microvascular dysfunction contribute to the expanding injury zone. The central core of the infarct undergoes rapid necrosis due to severe energy failure.
This complex sequence of molecular and cellular events unfolds over minutes to hours, ultimately determining whether tissue survives or undergoes permanent damage. The resulting ionic imbalance leads to a dangerous influx of sodium and calcium ions, while potassium leaks out into the extracellular space.
NMDA Receptor Blockade in the Ischemic Cascade
Microglia and astrocytes become activated, shifting from a protective to a detrimental role as they release cytotoxic compounds. This electrochemical disruption is a key early marker of distress and triggers a cascade of downstream effects, including the pathological opening of glutamate receptors.
