Backgrounds and/or triggers of dementia are vague except brain diseases such as cerebral stroke, brain injury, alcoholism, and schizophrenia. However, the backgrounds and/or triggers of patients who suffer from severe behavioral psychological symptoms of dementia (BPSD) and may require hospitalizations in institutions that specialize in the treatment of severe BPSD have not been specifically studied. In this work, we retrospectively investigated, through family interviews, the backgrounds and/or triggers of patients with BPSD hospitalized in Sendai Tomizawa Hospital, one of the psychiatric dementia hospitals.
