2026 March - 23 articles

Cover Story: This review delves into Alzheimer’s disease, a growing neurodegenerative concern. It assesses current therapies, highlighting cholinesterase inhibitors and NMDA antagonists, and explores the role of medicinal plants as potential treatments. While conventional drugs offer symptom relief, they do not stop disease progression. Emerging immunotherapies show promise but face safety and cost challenges. Notably, natural products such as huperzine A and curcumin show potential through their anti-inflammatory and antioxidant activities. The studies suggest that plant-derived compounds may enhance long-term management of Alzheimer’s by targeting multiple disease pathways. View this paper
