Organic versus mixed specialist older adult inpatient mental health units for people with dementia.

Dementia presents a major public health challenge to healthcare providers globally. When older people with dementia need inpatient mental healthcare, they can be cared for in one of two different types of older adult ward. These patients can either be admitted to an organic inpatient ward for people with dementia or the subtypes of dementia, or they can be admitted to a mixed inpatient ward for older people who have either functional or organic conditions.
