Dementia

Dementia is not a natural ageing process, but is always due to disease.

Dementia is a condition where brain function is impaired. Impaired memory is the most prominent symptom, although the ability to reason and judgment are often impaired as well, and changes can also be observed in the person's personality, mood and behavior.

Dementia is not a disease in itself. Dementia is a syndrome. That means it is a group of symptoms that may be due to many different diseases. In the text on this website, the words "dementia diseases" are thus used for the diseases that cause dementia, such as Alzheimer's disease or vascular dementia.
