In 2017, more than 87,000 deaths were related to dementia, accounting for 26% of the total over 75, according to data from Public Health England. Ten years ago, 40,000 deaths from dementia accounted for 13% of the total. At the same time, cancer accounted for 22% of all deaths among seniors in 2017 (74,000), an increase of less than 1% since 2007. Helen Davies, Public Affairs Officer of the Alzheimer's Association & # 39; Research UK said, "We know that dementia is not only the leading cause of death in the UK, but also the health crisis of our time." In the UK, 850,000 people have dementia – a figure that should reach more than one million by 2021 with the aging of the population.

Ms. Alzies said: "Alzheimer's Research UK calls on the government to spend only 1% of the cost of dementia research to improve the lives of people with dementia."

Sally Copley, director of policy and campaigns at the Alzheimer Society, said, "In 10 years, the number of dementia deaths has doubled, but we have seen no increase in investment in dementia research to combat this devastating disease.

"Cancer researchers are four times more likely than dementia researchers, although dementia is the most serious health crisis of our time."

The other leading causes of death are heart disease, chronic obstructive pulmonary disease and stroke.
