Dementia is an illness that leads to the decline of the brain and its abilities in judgement, language, planning, and behaviour. It can affect adults of any age, although it is more likely to occur in those above 65 years old.
Dementia is caused by a variety of diseases and injuries that primarily or secondarily affect the brain, such as Alzheimer’s disease or stroke.
Dementia is one of the major causes of disability and dependency among older people worldwide. It is overwhelming not only for the people who have it, but also for their caregivers and families. There is often a lack of awareness and understanding of dementia, resulting in stigmatization and barriers to diagnosis and care. The impact of dementia on caregivers, family and societies can be physical, psychological, social and economic.
