PHYSICAL ILLNESS
Dementia results in progressive loss of ability in activities of daily living and physical activity. Multiple mechanisms lead to functional loss, including cognitive and neurological decline, comorbidities, acute illness, injuries, delirium, inactivity, deconditioning, and restriction of opportunities, especially if people experience stigma or family members are concerned about safety. Dementia (and a possible precursor state, mild cognitive impairment) confers an increased risk of crises, including acute physical illness and a twofold increased risk of falls.The prevalence of dementia increases exponentially with age, with 20% of 80 year olds affected.In this study we hypothesised that exercise based, functionally directed rehabilitation would improve physical reserve, promote safe performance of activities, reduce falls, and enhance recovery from intercurrent illness or injury in people with early dementia or mild cognitive impairment, and hence improve activities of daily living. To develop and evaluate this approach, we undertook a programme of research.
