Question

Accepted Answer

Nearly 10 Million New Dementia Cases Diagnosed Annually Worldwide

Globally, approximately 10 million new cases of dementia are diagnosed each year. This figure underscores the significant and ongoing challenge posed by brain diseases that affect memory, thinking, and an individual's ability to function. Dementia is recognised as the seventh leading cause of death worldwide and is a major contributor to disability and dependency in older populations.
Modifiable Risk Factors Contribute Significantly to Dementia Incidence

The World Health Organisation (WHO) has indicated that a substantial portion, up to 45 per cent, of dementia risk can be attributed to factors that are amenable to change. These modifiable risk factors include engagement with tobacco products, excessive alcohol consumption, social isolation, a lack of physical activity, and exposure to air pollution. Furthermore, the presence of noncommunicable diseases (NCDs) such as high blood pressure and diabetes also plays a crucial role in dementia risk.
Global Dementia Prevalence and Impact

Currently, the number of people living with dementia worldwide exceeds 57 million. The impact of this condition extends beyond individual health, affecting families and communities by presenting profound challenges to dignity, independence, and overall well-being. Devora Kestel, director of the WHO’s NCDs and mental health department, highlighted that dementia is not a distant concern but a reality that touches everyone.
Prevention Strategies Emphasised by WHO Guidance

Given the absence of a cure or widely accessible treatments for dementia, the WHO strongly advocates for prevention as the most effective strategy to mitigate its growing burden. Updated guidance from the UN health agency provides evidence-based recommendations for health workers and policymakers to implement. These guidelines aim to foster early awareness and intervention, promoting cognitive health and reducing the incidence of dementia in the coming decades.
