Background The symptoms of geriatric syndromes and the behavioural and psychological symptoms of dementia (BPSD), in addition to clinical conditions, are associated with hospital admission among dementia patients. However, the principal factors that necessitate hospital admission among dementia patients have not been fully elucidated. Methods We retrospectively reviewed the data in the medical and autopsy reports of patients who had been treated at a hospital in Toyohashi, Japan. Each patient had been hospitalized sometime between 2012 and 2016 and underwent a brain autopsy. Dementia and the subtypes of dementia were diagnosed neuropathologically. Information about patients’ general backgrounds, clinical conditions at the time of admission, and the geriatric syndrome symptoms and BPSD before admission was collected; comparisons were then made between patients with and without dementia and among those with the different major subtypes of dementia. Then, the factors relating to hospital admission of dementia patients were comprehensively evaluated by using principle component analysis. Results Of the 128 eligible patients, 100 (78.1%) had dementia. In the comparison of patients with and without dementia, patients without dementia were younger at both admission ( P = 0.034) and death ( P = 0.003). Among the patients with dementia with Lewy bodies, delusions had a significantly high prevalence ( P = 0.014). Principal component analysis identified nine components (disinhibition, irritability/lability, agitation/aggression, anxiety, delusions, sleep/night‐time behaviour disorders, hallucinations, aberrant motor behaviour, and speech impairment) as the principal factors related to hospital admission among dementia patients. Thus, BPSD were identified as principal factors. Conclusions Compared to other factors, BPSD are more likely to cause dementia patients to be admitted to hospital. The present results indicate that measures should be taken to ameliorate the difficulties associated with caring for patients with BPSD at home.
