Memory loss is a serious problem and it is important to first consult with your doctor to determine the underlying cause. Depending on the diagnosis, there are a variety of medications that may be prescribed to treat memory loss, such as acetylcholine esterase inhibitors which are used to treat Alzheimer's disease, and other medications which are used to treat depression, anxiety, insomnia, and other conditions that can affect cognitive function. Some natural supplements may also be beneficial, such as omega-3 fatty acids, ginkgo biloba, and huperzine A, which have been shown to improve cognitive function. Finally, lifestyle modifications, such as following a healthy diet, engaging in regular physical activity, and participating in stimulating activities, may also help to improve memory.
