The risk of developing dementia is falling, thanks to lifestyle improvements such as reductions in smoking, new research has found. Researchers have said that while the overall number of cases is rising due to the population living longer, an individual’s chances of having the disease is going down | Alzheimers Research UK
International experts have presented research indicating that dementia incidence rates may be falling by up to 15% decade on decade. Analysing data from seven population-based studies in the United States and Europe, Prof Hofman and a global team of researchers set out to determine changes in the incidence of dementia between 1988 and 2015.
Of 59,230 individuals included in the research, 5,133 developed dementia. The rate of new dementia cases declined by 15% per decade, a finding that was consistent across the different studies included in the analysis.
The findings will be discussed at the Alzheimer’s Research UK Conference 2019 in Harrogate.

In This video, lead author Albert Hofman, discusses trends in dementia incidence over the last three decades at the Alzheimer’s Research UK Conference 2019. Prof. Hofman goes on to explain the reasoning behind these trends.
Recorded Dementia Diagnoses – July 2018 | NHS Digital
NHS Digital collects and publishes data about people with dementia at each GP practice, so that the NHS (GPs and commissioners) can make informed choices about how to plan their services around their patients needs.
This publication includes the rate of dementia diagnosis. As not everyone with dementia has a formal diagnosis, this statistic compares the number of people thought to have dementia with the number of people diagnosed with dementia, aged 65 and over.

Figures released by the Office for National Statistics (ONS) show there has been a 7.4% increase in deaths from all forms of dementia – with a 5.3% increase in deaths from vascular and unspecified dementia, and a 13.9% increase in deaths from Alzheimer‘s disease
The Office for National Statistics latest figures reveal there were 533,253 deaths registered in England and Wales in 2017, a 1.6% increase from 2016. Data for 2017 shows that in total, there were 67,641 deaths attributed to Alzheimer’s disease or other forms of dementia – 13% of the total deaths recorded that year. This is a rise from 2016, when there were 62,948 deaths from dementia (12% of all those recorded).
Alzheimer’s Research UK is calling for urgent investment in dementia research, following the release of these new statistics. Dr Matthew Norton, Director of Policy and Strategy at Alzheimer’s Research UK, said:
“These figures yet again underline the overwhelming impact of dementia for the UK, and for hundreds of thousands of families who are hit by the condition. With one in four hospital beds occupied by someone with dementia and deaths from the condition rising, we must take urgent action. As well as support for dementia research, the condition must become a priority for the NHS 10-year plan”.

Number of people diagnosed with Dementia according to GP records up to the 31 March 2018
This publication presents at England level: recorded prevalence and how this compares with research based studies at different ages, and how prevalence differs at different ages depending on comorbidity; CCG level: the rate of emergency hospital admissions for dementia per person recorded with a dementia diagnosis.
- Recorded dementia prevalence at 31 March 2018 was 0.765 per cent (1 person in 131). When considered alongside monthly data previously collected, this indicates a decrease in recorded prevalence from March 2017 (0.766) to March 2018 (0.765).
- The number of people over 65 with dementia was estimated to be 645,507. Of these, 67.5 per cent have a coded dementia diagnosis recorded.
- 9.3 per cent of patients with a recorded dementia diagnosis were prescribed antipsychotic medication in the 6 weeks to 31 March 2018.

This article argues that there is a potential for better disease prevention and for care to offer more improvements to the lives of a growing number of people with dementia.
To reduce dementia incidence, article authors recommend active treatment of hypertension for all people over 45 without dementia. Furthermore, they estimate that interventions into such risk factors as childhood education, exercise, maintaining social engagement, reducing smoking, and management of hearing loss, depression, diabetes, and obesity might have the potential to delay or prevent a third of dementia cases.

Dementia and Alzheimer’s disease remain the leading cause of death in England and Wales, accounting for 12.0% of all deaths registered in 2016, up from 11.6% in 2015, according to new Office of National Statistics (ONS) figures.
This increase is attributed by ONS to people living longer, due to improved lifestyles and medical advances. With people living longer and surviving other illnesses, the number of people developing dementia and Alzheimer disease is increasing. Improved identification and diagnosis of dementia has also contributed to the increase.
Here, the Alzheimer’s Society responds to the figures showing dementia remains the leading cause of death.
Annual report brings together GP-level data on recorded dementia diagnoses.
The latest statistics on dementia prevalence in England have been published by NHS Digital. Recorded Dementia Diagnoses 2016/17 uses information provided by general practices in England about the number of dementia diagnoses in their individual practice.
For each general practice included in this data collection, NHS Digital receives a count of the number of patients with a dementia diagnosis in their clinical record, as well as a count of the total number of registered patients at the practice.
- 422,000 people aged 65 and over in England have a recorded dementia diagnosis. This represents 1 in 23 people aged 65+ registered with a GP.
- 1 in 5 women aged 90 or over have a recorded dementia diagnosis, the highest prevalence for any group.
- There were 207,797 unique patients aged 65 and over admitted to hospital in an emergency with a diagnosis of dementia (provisional data).
- Dementia is more common in people with learning disabilities, particularly for individuals with Down syndrome who appear to develop dementia at younger ages
The report also covers topics such as:
- Dementia related emergency hospital admissions (England)
- Dementia prevalence for patients with learning disabilities
- Recorded dementia diagnoses by ethniticy and age
