Lay summary
The ageing demographic means prevention of dementia is an international and national priority. People with mild cognitive impairment (MCI), an early (prodromal) stage of dementia, are also at high risk of falls. Cognitively stimulating exercise may both prevent dementia and falls (must not cause falls). We aim to test a model of care for dementia prevention in people with MCI using randomised controlled trial and cost effectiveness methods. The Ronnie Gardiner Method (RGM) is compared with a falls prevention programme (SAYGO). RGM is a cognitively challenging music and movement activity programme where trained practitioners use rhythmical cross body movement to music for neurological rehabilitation. Up to 190 people will be invited through the Dementia Prevention Research Clinics, where MCI is diagnosed with clinical certainty, in three sites. A Māori sub-study will redevelop RGM by Māori, for Māori to test feasibility. Improved cognition will prolong independence and enhance the silver economy.
