There is increasing interest in physical activity as a response to the harm caused by dementia. The focus has been upon interventions to prevent or delay symptoms or to support people living with the condition to reminisce. Whilst this is welcome, there are other features inherent to physical activity that remain unrecognised or underutilised and, consequently, its full potential for good is unrealised. Most prominent is the ability physical activity has to enable participants to claim and sustain a place in the world through what they do, crucial to a context where the impact of dementia tends to annihilate this for those living with the condition. The article addresses this gap. In doing so, it presents key findings. These include (1) highlighting the fundamental importance of features such as person-centred care, human rights and social citizenship to enabling people with dementia to live lives of quality and (2) identifying synergies with these features and what physical activity can offer; for example, emphasising the value of bringing these together to illustrate how physical activity can contribute to enabling people with dementia to live lives characterised by quality, and the maintenance of their place in the world. The article concludes by suggesting what must come next to ensure physical activity can play the fullest role possible.
