WHO: Introduction of dementia

Dementia is a global health concern, characterized by a decline in cognitive functions such as memory, reasoning and communication skills. It affects an estimated 50 million people worldwide and is projected to affect 82 million by 2030 and 152 million by 2050. Dementia is a result of physical changes in the brain caused by diseases or conditions, and is not a natural part of aging. The most common cause of dementia is Alzheimer’s disease, accounting for 60-70% of all cases. Other causes include vascular dementia, dementia with Lewy bodies, and frontotemporal dementia. There are also several risk factors for developing dementia, such as age, genetics, lifestyle and environmental factors.

There is currently no cure for dementia, but treatments are available to manage the symptoms. These include medications, lifestyle changes, and psychological and social interventions. Early diagnosis and intervention is essential for managing the symptoms of dementia, and regular check-ups with a doctor can help identify the onset of dementia early.

The World Health Organization (WHO) is working to raise awareness about the impact of dementia and to promote the development of effective policies and plans to support those affected by the disease. The organization is also working to improve access to quality care and support for those with dementia, and to encourage research into finding a cure for the disease.
