Prevalence and determinants of undetected dementia in the community: a systematic literature review and a meta-analysis.

Objectives: Detection of dementia is essential for improving the lives of patients but the extent of underdetection worldwide and its causes are not known. This study aimed to quantify the prevalence of undetected dementia and to examine its correlates.

Methods/setting/participants: A systematic search was conducted until October 2016 for studies reporting the proportion of undetected dementia and/or its determinants in either the community or in residential care settings worldwide.

Dementia care in the acute district general hospital.

Morbidity and mortality for any physical illness treated in hospital and complicated by dementia is increased. Length of stay is also prolonged for any physical illness and dementia. Poor uncoordinated hospital care contributes to increased rates of nursing home admissions.
