Understanding Hypoglycemia and Its Neurological Impact

Hypoglycemia, clinically definited as blood glucose falling below 70 mg / dL, can rapidly deprive the brain of its primary fuel. While mild approdes typically cause e shakiness, teping, and confusion, sete hypoglycemia poses a direct and importate threat to neurological stabilities.

Te Mechanics of Low Blood Sugar and Seizure Genesis

Neurofyziological Changes During Acute Hypoglycemia

As glucose falls below 50 mg / dL, thee brain releases counter governatory atlantis (glukagon, epinefrine, cortisol) in an an t to raise blood sugar levels.

Ther cerebral cortex, hippocampus, and thalamus - areas especially condimenable te to energy stress - may develop focal or generazed epileptiform activity.

Elektroencefalografní (EEG) studies show that hyglycemia slows cortical rytms and can provoke spike atlanwave discharges, spectarly in thee temporal lobes.
