What are the different types of dementia?
We look at some common types of dementia.
Common types of dementia
- Alzheimer’s disease
Alzheimer’s disease is the most common form of dementia. It is caused by damage to the nerve cells in the brain and results in forgetfulness, trouble with speech and difficulty with everyday tasks.
- Vascular dementia
Vascular dementia is the second most common form of dementia. It is caused by tiny strokes in the brain and affects behaviour, speech and functioning.
- Dementia with Lewy bodies
Dementia with Lewy bodies is caused by tiny protein deposits (Lewy bodies) being present in the nerve cells in the brain. They disrupt normal brain function, causing difficulties with memory, language and reasoning.
Other types of dementia
- Frontotemporal dementia
This group of disorders is caused by progressive cell damage in the frontal lobe (front part of the brain) or temporal lobe (area of the brain behind the ears). Symptoms of frontotemporal dementia may include changes in behaviour, personality and language, more so than forgetfulness.
- Alcohol related dementia
People who consume excessive amounts of alcohol over a long period of time can also develop dementia.
- Early onset dementia
Early onset dementia is rare and is used to describe the onset of any type of dementia before the age of 65. It is also referred to as younger onset dementia, younger onset Alzheimer’s or early onset Alzheimer’s.
Whatever kind of dementia the person is living with, loved ones and carers can face similar challenges and questions. To talk to a real person about what you can do for someone living with dementia and what support is available, call Bupa's Aged Care Support Line.
