Many dementia patients fail to have the proper checks when they are in hospital, an audit of care has found.
The National Audit of Dementia found some improvements since its first analysis of care in England and Wales in 2011.
But it says too few patients have their mental state assessed, and information is often not shared properly.
The government says that improving dementia care is a priority in the NHS.
BBC Breakfast spoke to Ann Knowles, whose aunt Edna has vascular dementia, and George McNamara from the charity, the Alzheimer's Society.
