Curcumin and Neuroprotection: A Promising Herbal Strategy for Alzheimer’s and Parkinson’s Disease

Curcumin, a bioactive compound derived from *Curcuma longa*, has gained significant attention for its neuroprotective properties, particularly in neurodegenerative diseases such as Alzheimer’s and Parkinson’s. This study aimed to evaluate the neuroprotective effects of curcumin in a mouse model of neurodegeneration induced by oxidative stress and inflammation. A total of ­40 Swiss albino mice­ were divided into four groups: a control group, a disease model group, and two treatment groups receiving curcumin at doses of ­100 mg/kg and 200 mg/kg­ for ­21 days­. Behavioral tests, including the Morris water maze and rotarod test, were conducted to assess cognitive and motor functions. Biochemical analyses were performed to measure oxidative stress markers (MDA, SOD, and GSH) and inflammatory cytokines (TNF-α and IL-6) in brain tissues. The results showed that curcumin significantly improved cognitive and motor performance in treated mice compared to the disease model group (­p < 0.01­). Curcumin administration reduced oxidative stress by ­35%­ and decreased inflammatory cytokine levels by ­40%­ in the brain. Histopathological examination revealed a ­30% reduction­ in neuronal damage in the curcumin-treated groups. These findings suggest that curcumin exerts neuroprotective effects by mitigating oxidative stress and inflammation, which are key pathological mechanisms in Alzheimer’s and Parkinson’s diseases. This study highlights the potential of curcumin as a natural therapeutic agent for neurodegenerative disorders, addressing the need for safer and more effective treatments.
