The number of people with dementia is expected to increase globally. People with dementia are not affected in isolation and any intervention should also support their families and carers. Intervention is best delivered using a relationship-centred approach and a case management model. Case management has an established and successful history in supporting people with long-term conditions and those with a diagnosis of severe mental illness. This article, the last in this dementia series, discusses the Admiral Nursing case management approach to supporting patients and families affected by dementia, and provides recommendations for establishing a gold standard model of case management.
