Current treatments offer only symptomatic relief and are often associated with adverse effects. In the search for alternative therapies, <em>Vinca minor</em>, a medicinal plant rich in alkaloids and antioxidants, has shown promising neuroprotective potential. <strong>Objective:<span> </span></strong>The<span> </span>aim<span> </span>of<span> </span>the<span> </span>study<span> </span>is<span> </span>to<span> </span>evaluate<span> </span>the<span> </span>neuroprotective<span> </span>effects<span> </span>of<span> </span>Vinca<span> </span>minor<span> </span>leaves<span> </span>extract<span> </span>against<span> </span>chemically<span> </span>induced Alzheimer’s disease in experimental animals. <strong>Methods: </strong>Male<span> </span>Wistar rats<span> </span>were divided into five groups, including normal control, disease control, standard drug, and two test groups receiving <em>Vinca minor </em>extract. A<span> </span>behavioral assessment was conducted using the radial arm maze and the novel object recognition test. Biochemical estimations included acetylcholinesterase (AChE), glutathione (GSH), nitric oxide (NO), and catalase (CAT) levels. Histopathological analysis of the brain tissue was performed to assess neuronal integrity. <strong>Results: </strong>Treatment with <em>Vinca minor </em>significantly improved behavioral performance, enhanced antioxidant enzyme levels, reduced<span> </span>AChE<span> </span>and<span> </span>NO<span> </span>levels,<span> </span>and<span> </span>preserved<span> </span>neuronal<span> </span>architecture<span> </span>in<span> </span>hippocampal<span> </span>regions<span> </span>compared<span> </span>to<span> </span>the<span> </span>disease<span> </span>control<span> </span>group. <strong>Conclusion:<span> </span></strong>The<span> </span>findings<span> </span>suggest<span> </span>that<span> </span><em>Vinca<span> </span>minor<span> </span></em>leaf </span><span>extract<span> </span>exerts<span> </span>cognitive-enhancing<span> </span>and<span> </span>neuroprotective<span> </span>effects,<span> </span>potentially through antioxidant and anticholinesterase mechanisms, supporting its use as a natural therapeutic option in<span> </span>AD management.</span></p>
