Presymptomatic Diagnosis and Prevention of Alzheimer's Disease


Japanese (日本語)

Our missions

We aim to protect the human dignity of aged people and their families by establishing presymptomatic diagnosis and preventive medicine against Alzheimer’s disease. We will also make the presenile Alzheimer’s disease preventable.

We will contribute to keeping the social security mechanisms sustainable. We will fight tax increases, which will be caused by the drastic aging of human populations in coming years.
