Dementia is an umbrella term that describes the symptoms you may experience when you have any one of a number of progressive neurological disorders.
Symptoms can include memory loss, difficulties with thinking, problem-solving or language. As a result of changes in the brain, a person with dementia may also experience changes in their mood or behaviour, and as the dementia progresses it can affect daily life and cognitive abilities.
No two people with dementia have the same experience, there are a few common symptoms but specific symptoms will depend on the part of the brain which was damaged and the type of disease which has caused the dementia, and often their life experiences.
