Опубликована: Май 1, 2024

Abstract: Alzheimer's disease (AD) is a progressive neurodegenerative disorder characterized by cognitive decline, memory loss, and impaired daily functioning. While there currently no cure for AD, several pharmacotherapeutic targets management strategies have been explored. Additionally, traditional medicinal plants gained attention their potential role in AD management. Pharmacotherapeutic include amyloid-beta (Aβ) aggregation, tau protein hyperphosphorylation, neuroinflammation, oxidative stress, cholinergic dysfunction. Traditional plants, such as Ginkgo biloba, Huperzia serrata, Curcuma longa (turmeric), Panax ginseng, demonstrated the ability to modulate these through bioactive compounds. biloba , instance, contains flavonoids terpenoids that exhibit neuroprotective effects reducing Aβ deposition enhancing cerebral blood flow. serrata natural source of huperzine A, has acetylcholinesterase-inhibiting properties, thus improving function. enriched with curcumin, exhibits anti-inflammatory antioxidant effects, potentially mitigating neuroinflammation stress. ginseng's ginsenosides shown anti-amyloidogenic properties. The investigation complementary approach offers advantages, including lower risk adverse multi-target interactions. Furthermore, cultural knowledge utilization provide rich information development new therapies. However, further research necessary elucidate precise mechanisms action, standardize preparations, assess safety efficacy remedies. Integrating medicinal-plant-based therapies modern pharmacotherapies may hold key more comprehensive effective treatment.
