Review/Advances in Neurological Therapeutics (2020). Dementia

Abstract

With the aging of society, the number of dementia patients in Japan continues to increase, with the Ministry of Health, Labor and Welfare predicting 4.62 million dementia patients in 2012 and another 4 million patients with mild cognitive impairment. In other words, about 8.6 million people have dementia or are in the preliminary stages of the disease. When this number is compared with the number of patients with other diseases announced by the ministry in 2014, it is not as high as the number of patients with hypertension (10.1 million), but it is much higher than the number of patients with diabetes (3.16 million). This increase is not limited to Japan, the same trend is observed worldwide, and many research results have been reported in response to this trend.

We summarized and reported the results of the relatively large–scale studies on dementia treatment reported in 2020.
