Valoración funcional en la demencia grave

Severe dementia is currently one of the main causes of dependence and is defined as cognitive impairment that interferes with the performance of basic activities of daily living. However, in clinical practice severe dementia is difficult to define.Assessment of the ability to perform activities of daily living is a key factor in patients with severe dementia, since functional impairment is a defining feature. Assessment allows an accurate prognosis to be made and a care plan to be established, as well as the effectiveness of the intervention to be evaluated, when necessary.Functional assessment in dementia is complex, since functional status is the expression of multiple interactions, especially in geriatric patients. Functional status is measured by functional scales. In severe dementia, these scales must evaluate basic activities of daily living in the different types of dementia with high sensitivity to changes and strong discriminatory capacity. They should also be culturally adapted and validated in the community and institutional settings. Consensus should be established on the use of these instruments to allow them to be standardized and their results to be compared.
