Abstract

Suicide is a major public health issue in many industrialized countries. It is one of the top ten causes of death and older age is a significant risk factor for suicide. For example, in Japan older adults (age ≥ 65) shared about 18.5% of total population but account for 24% of all suicide, in Taiwan, older adults representing 12.4% of the total population and account for 28.9% of suicide death. Dementia is a broad term for a progressive deterioration in memory ability and dementia patients ran higher risk for suicide.
