Dementia

This is a start page for learning about dementia (from the Latin for "without mind").

What is dementia?

Dementia is a gradual, serious loss of global cognitive ability in a previously unimpaired person, beyond what might be expected from normal aging.

Dementia is a very significant world-wide health care issue.

How does dementia feel?

The numbers

36 million people in the world have dementia (Banerjee, 2012)
It will double by 2030 and there will be 115 million with dementia by 2050
The social cost is enormous - US$600 billion per year (bigger than the biggest company of the world and biggest than cancer, diabetes, etc., i.e., around 1% of the world's economy, equivalent to the 18th biggest economy of the world)
60% of the costs of aging care are due to dementia

Myths about dementia

It is not a normal part of ageing
That nothing can be done to help prevent or treat dementia
Stigma of dementia prevents discussion with the person with dementia
Having dementia means that a person is completely dependent

Types of dementia

Here is a description of some of the more well-known types of dementia (Access Economics, 2009) -

Alzheimer’s Disease, most common and usually affects the temporal lobes of the brain with consequent deterioration in memory,
Vascular Dementia, caused by mini strokes and more sudden onset than Alzheimers, can occur anywhere in the brain,
Dementia with Lewy Bodies (abnormal proteins form in certain areas of the brain) tends to affect the visual cortex among other areas of the brain,
Frontal Lobe and Fronto-Temporal Dementia (eg Pick’s Disease where abnormal amounts of tau protein form in nerve cells)
Alcohol-related Dementia (Korsakoff’s Syndrome)
Parkinsons Disease (affects nerve cells’ production of dopamine, which affects muscle movement and balance)
Huntingtons Disease is usually hereditary (behaviour changes such as irritability, moodiness, restlessness, paranoia and psychosis may be evident before movement problems emerge such as jerking movements, unsteady walking, involuntary facial movement)
AIDS-related Cognitive Decline

What is needed?

National Dementia Strategies to prioritise health-care goals and strategies
- Vision
- System change
- Ambition in scale
- Investment
- Commitment over time
- Leadership
Health Promotion campaigns to educate carers, families, health professionals
Good-quality earlier diagnosis and intervention
- Only a third of most of people with dementia received any special health care assessment or diagnosis. When they do it is:
  - late in the illness too late to enable choice
  - at a time of crisis
  - too late to prevent harm or crises.

Quality of life

Quality of life (QOL) is unrelated to severity of dementia. However, there is considerable variability in QOL. Quality of understanding, diagnosis, and care then are important aspects of the health and well-being of those with dementia.
