Dementia is a disease, usually chronic, which affects memory, thinking, orientation, comprehension, calculation, language and learning capacity. Although, in many cases it is related to age, dementia is not a normal consequence of aging.
Dementia is one of the main causes of disability and dependency among the elderly around the world. The consequences of the disease can be distressing not only for patients, but also for their caregivers and relatives who suffer its effects indirectly because, as the World Health Organization points out “the impact of dementia on carers, family and societies can be physical, psychological, social and economic”.
