People with dementia are known to be frailer when compared to healthy aged individuals. Indeed, dementia is an obstacle to physical activity, leading to sedentary lifestyle, risk of sarcopenia, loss of mass and therefore frailty.

Frailty is described as a state of decreased reserves of several physiological systems, with a limited capacity to withstand stressors. Aged people get more vulnerable and less able to adapt to troubles or health issues, which increases the risk for developing dementia.

While dementia and frailty are conditions found in older adults, many studies have already highlighted the benefits of physical activity in such context on cognition, physical and daily functioning or well-being.

Adherence to the proposed exercise programme is definitely one of the key elements needed to promote physical activity. According to previous studies, exergaming has proven to be effective for people with dementia as it enhances patients' participation, while positively influencing balance, dual-task performance and psychomotor speed.

The present study focuses on the effects of exergaming on frailty but also on other aspects such as physical functioning, physical activity and activities of daily living (ADL) in older people suffering from dementia.
