People living with dementia, their carers and health professionals are attending a national conference in Nottingham today.
The aim of the event at the East Midlands Conference Centre is to promote better understanding of the disease and the needs of those affected by it.
The conference heard an emotional speech from a man who cared for his wife after she was diagnosed with Alzheimer's.
Several members of the audience were in tears as he described making the heart-breaking decision to put her into a care home.
Dementia is estimated to cost the UK £23bn a year.
The prevalence of the disease will continue to rise with the country's ageing population.
