(±)-Huperzine A is primarily used in the treatment of cognitive disorders, particularly Alzheimer's disease. It functions as an acetylcholinesterase inhibitor, which helps increase the levels of acetylcholine in the brain, thereby improving memory and cognitive function. Additionally, it has shown potential in treating other neurodegenerative conditions, such as vascular dementia and age-related memory decline. Beyond its neurological applications, (±)-Huperzine A is also explored for its neuroprotective properties, which may help in reducing neuronal damage caused by oxidative stress or injury. In traditional medicine, it has been used to enhance learning and memory, making it a subject of interest in both clinical and research settings.
