'Today, one in three people have a family member or close friend with dementia.
'Despite this, there is still a worrying lack of public understanding about the condition, which is why we have developed the dementia hotspots maps.
'As the UK's leading dementia research charity, one of our biggest challenges is to empower people with the knowledge that this cruel and unforgiving condition can be defeated.
'Dementia is not an inevitable part of ageing, it is caused by diseases.'
