Dementia Prevention and Aromatherapy in Japan.

Until recently, it was thought that dementia prevention was not possible. However, a recent paper reported that 40% of the risk factors for developing dementia are modifiable. Large-scale clinical studies on dementia prevention and various initiatives to reduce the risk of developing dementia have been made worldwide. In addition to the introduction of a global initiative in dementia prevention, I also introduce the results of our research on the development of the Tottori method dementia prevention program and aromatherapy to approach olfactory impairment in Alzheimer's disease. ©2022 Tottori University Medical Press.
