An expert recently shared on ITV that nearly half of individuals diagnosed with dementia can potentially prevent its onset by making simple lifestyle adjustments. During an appearance on This Morning, renowned dementia specialist Professor Catherine Mummery emphasized the importance of targeting specific areas of the body to mitigate the risk.
Statistics indicate that as of 2026, the UK has over 1.1 million dementia patients, with projections showing a continual rise due to the aging population.
A significant report has revealed that one in three individuals born in the UK will develop dementia in their lifetime. Despite commonly being associated with old age, there are more than 70,000 cases of young-onset dementia in the UK, where symptoms manifest before the age of 65.
The “Diagnosis Gap” in the NHS records indicates a discrepancy, with an estimated 500,000–600,000 formal dementia diagnoses, leaving a substantial portion undiagnosed.
Professor Mummery stressed the importance of monitoring blood pressure as an initial step in dementia prevention, highlighting that lifestyle modifications, such as managing risk factors like blood pressure, cholesterol levels, diabetes, and smoking, can significantly reduce the risk, particularly in vascular dementia cases.
Regarding impactful measures, she recommended three key factors: regular physical exercise at least three times a week, engaging in mental activities that challenge and stimulate the brain, and maintaining a healthy diet rich in fresh produce while avoiding processed and sugary foods to lower the risk of developing any form of dementia.
Dementia has emerged as a leading cause of death in the UK, accounting for more than 10% of annual deaths and costing the economy billions each year, encompassing healthcare expenses, social care, and the invaluable contributions of over a million unpaid family caregivers.
Healthcare authorities suggest that around 40% of dementia cases could potentially be prevented or delayed by addressing modifiable risk factors, emphasizing the critical role of heart health in brain function. An essential recommendation is undergoing an NHS Health Check, available for individuals aged 40–74, to detect early signs of conditions like high blood pressure associated with dementia.
