This preclinical study evaluated the neuroprotective effects of taurine in a rat model of sporadic Alzheimer's disease induced by intracerebroventricular (ICV) injection of streptozotocin (STZ). Rats received a single bilateral ICV-STZ injection (3 mg/kg), leading to cognitive deficits, oxidative stress, and cholinergic dysfunction. Taurine was administered orally at 50 mg/kg
