Dementia is a syndrome, usually of a chronic or progressive nature, caused by a variety of brain illnesses that affect memory, thinking, behaviour and ability to perform everyday activities.
The number of people living with dementia worldwide is currently estimated at over 50 million and will almost triple by 2050.
Dementia is overwhelming not only for the people who have it, but also for their caregivers and families. There is a lack of awareness and understanding of dementia in most countries, resulting in stigmatization, barriers to diagnosis and care, and impacting carers, families and societies physically, psychologically and economically.
The annual global cost of dementia is estimated to be US$ 818 billion. Nearly 85% of costs relate to family and social, rather than medical, care. The annual costs of caring for people with dementia are expected to rise to US$ 2 trillion by 2030.
People can reduce their risk of dementia by getting regular exercise, not smoking, avoiding harmful use of alcohol, controlling their weight, eating a healthy diet, and maintaining healthy blood pressure, cholesterol and blood sugar levels.
Caring for a person with dementia can be overwhelming for carers. The stresses include physical, emotional and economic pressures. Carers require support from the health, social, financial and legal systems.
The principal goals for dementia care are:
*diagnosing early;
*optimising physical health, cognition, activity and well-being;
*detecting and treating behavioural and psychological symptoms; and
*providing information and long-term support to carers.
Currently there is no cure for dementia. However, much can be done to support people living with dementia. Early diagnosis is important; regular health checks can help to ensure that accompanying physical illnesses are diagnosed and treated; and health and social care systems, when adequately resourced, can ensure care at all stages of dementia.
Dementia-friendly initiatives are often set up by civil society organizations. Activities include dementia cafes for people affected to share experiences and seek advice; special signage in public spaces to make it easier for people with dementia to get about; and fundraising events to support research efforts.
More research is needed to develop new and more effective treatments and to better understand the causes of dementia. Research into interventions that address modifiable risk factors of dementia is still scarce.
To address this important health priority there are actions that can be taken:
* make dementia a public health and social care priority everywhere;
* increase dementia awareness and promote a dementia-inclusive society (including improve attitudes to, and understanding of, dementia);
* implement interventions aimed at reducing potentially modifiable risk factors for dementia;
* invest in health and social systems to improve diagnosis, treatment and care for people with dementia;
* support dementia carers and their families;
* improve health and social care monitoring of dementia, and
* increase research on dementia and promote innovation.
