Dementia patients admitted to hospital in England play "Russian roulette" with their health, a charity is warning.
The Alzheimer's Society said it had found "shocking" evidence of poor and variable care during its review.
The report, based on Freedom of Information (FOI) requests, found problems with falls, night-time discharges and readmissions, and said standards needed to improve urgently.
The Department of Health said the disease was a key priority.
One in four hospital beds is believed to be occupied by a person with dementia.
The Alzheimer's Society called for all hospitals to publish an annual statement of dementia care, to include information on satisfaction, falls, readmissions and staff training as part of its campaign to improve standards.
