Ageing population and better diagnosis have led to heart disease being knocked off top spot for first time, ONS says

Alzheimer’s disease and other dementias have replaced ischaemic heart disease as the leading cause of death in England and Wales for the first time.

Last year, 61,686 (11.6%) out of a total of 529,655 deaths registered in England and Wales were attributable to dementia, according to the Office for National Statistics (ONS).

The statisticians said an ageing population, better diagnosis, and lifestyle and treatment advances with respect to other illnesses were among the factors that had pushed dementia to the top of the list.

The mortality rate for dementia, which was the second leading cause of death for the previous four years, has more than doubled since 2010, while that of ischaemic heart disease declined sharply over the same period.

Martina Kane, senior policy officer at Alzheimer’s Society, said: “Today’s news that dementia and Alzheimer’s disease are the leading cause of death in England and Wales is a stark reminder that dementia remains a growing concern across the country. While the news represents improvements in diagnosis rates, general awareness and the accuracy of reporting, it also reflects that there are rising numbers of people with dementia.

“While there remains no cure for the condition, everyone who develops it will sadly still have the disease when they die. It is therefore essential that people have access to the right support and services to help them live well with dementia and that research into better care, treatments and eventually a cure remain high on the agenda.”

Ischaemic heart diseases were responsible for 11.5% of deaths last year, although it was still the leading cause of death for men, accounting for 14.3% of male deaths. Dementia, the leading cause of death for women, was responsible for 15.2% of all female deaths, up from 13.4% in 2014.

Hilary Evans, chief executive of Alzheimer’s Research UK, said the figures “call attention to the uncomfortable reality that currently, no-one survives a diagnosis of dementia”. He added: “With growing numbers of people living with dementia, we urgently need treatments that can stop or slow the diseases that drive this devastating condition.”



The ONS said there was likely to have been an increased reporting of dementia on death certificates because of dementia diagnosis incentives paid to GPs (which have since been scrapped), the prime minister’s challenge to improve dementia care and an agreed ambition that two-thirds of the estimated number of people with dementia in England should have a diagnosis.



Elizabeth McLaren, from the vital statistics outputs branch at ONS, said: “In 2015, dementia and Alzheimer’s disease became the leading cause of death in part because people are simply living longer but also because of improved detection and diagnosis. An updating of the international rules for determining the underlying cause of death is also a factor, with the increase in cases attributed to these conditions accompanied by falls in other causes.”



The most common causes of death last year after dementia and ischaemic heart disease were cerebrovascular diseases, such as strokes, chronic lower respiratory diseases, including chronic obstructive pulmonary disease, and lung cancer.



There was wide variation by age group. Dementia was the leading cause of death for people over 80 but it was the fourth leading cause of death for women aged 65 to 79 and not in the top five leading causes of death for men aged within that age group. Among men aged 35 to 49 suicide and injury/poisoning of undetermined intent was responsible for the most deaths, while for women of the same age group the leading cause of death was breast cancer.



If all cancers are grouped together, it was the most common cause of death, accounting for 27.9% of all deaths last year, compared with 26.2% caused by circulatory diseases, such as heart diseases and strokes.

Alzheimer’s Society estimates that there will be a million people with dementia in the UK by 2025, although research published earlier this year suggests that the number of new cases in recent years has been fewer than previously predicted.
