For people aged between 65 and 69, around 2 in every 100 people have dementia. A person's risk then increases as they age, roughly doubling every five years. This means that, of those aged over 90, around 33 in every 100 people have dementia.
There are many types of dementia including Alzheimer's disease, vascular dementia, frontotemporal dementia and Lewy body disease. Dementia can happen to anybody, but it is more common after the age of 65.
The greatest known risk factor for Alzheimer's and other dementias is increasing age, but these disorders are not a normal part of aging. While age increases risk, it is not a direct cause of Alzheimer's. Most individuals with the disease are 65 and older. After age 65, the risk of Alzheimer's doubles every five years.
Dementia is more common in people over the age of 65, but in some cases, it can also affect people in their 30s, 40s, or 50s. With treatment and early diagnosis, you may be able to slow down the progression of dementia and maintain mental function for a longer period of time.
Alzheimer's disease.
This is the most common cause of dementia.
As we age, our brains change, but Alzheimer's disease and related dementias are not an inevitable part of aging. In fact, up to 40% of dementia cases may be prevented or delayed. It helps to understand what's normal and what's not when it comes to brain health.
Cancers, infections, toxins and autoimmune conditions could all cause a fast decline in mental function, as well as the more common neurodegenerative causes of dementia such as Alzheimer's, strokes and Parkinson's disease.
More Evidence That Alzheimer's Disease May Be Inherited from Your Mother. Results from a new study contribute to growing evidence that if one of your parents has Alzheimer's disease, the chances of inheriting it from your mother are higher than from your father.
In 2022, it is estimated that almost 400,000 people in Australia have dementia. The estimated number of men with dementia increases from almost 100,000 in 2010 to over 300,000 in 2058. The estimated number of women with dementia increases from almost 200,000 in 2010 to over 500,000 in 2058.
Many people affected by dementia are concerned that they may inherit or pass on dementia. The majority of dementia is not inherited by children and grandchildren. In rarer types of dementia there may be a strong genetic link, but these are only a tiny proportion of overall cases of dementia.
Introduction: The five-word test (5WT) is a serial verbal memory test with semantic cuing. It is proposed to rapidly evaluate memory of aging people and has previously shown its sensitivity and its specificity in identifying patients with AD.
The current evidence indicates that while chronic stress may play a role in the development or progression of dementia, it does not necessarily cause dementia. Hopefully, further research can begin to uncover what role stress plays in a person's risk of developing dementia.
Physical activity. Doing regular physical activity is one of the best ways to reduce your risk of dementia. It's good for your heart, circulation, weight and mental wellbeing. You might find it difficult to start being more physically active, or worry it means doing an activity you don't enjoy.
Pneumonia is a common cause of death in people with Alzheimer's because the loss of ability to swallow means that food and beverages can enter the lungs and cause infection. Other common causes of death among people with Alzheimer's disease include dehydration, malnutrition, and other infections.
Age. Increasing age is the greatest known risk factor for Alzheimer's disease. Alzheimer's is not a part of normal aging, but as you grow older the likelihood of developing Alzheimer's disease increases.
A 2019 study published in Journal of Alzheimer's Disease, showed among 165 participants (45 with diagnosed neurodegenerative disease, 120 controls) a supine sleep position (on back, head at body level) for more than 2 hours per night increased the risk of dementia by almost four times (3.7 times greater).
Alzheimer's disease is the most common form of dementia. Alzheimer's disease is a physical brain condition resulting in impaired memory, thinking and behaviour. It disrupts the brain's neurons, affecting how they work and communicate with each other.

The Mini-Cog test.
A third test, known as the Mini-Cog, takes 2 to 4 minutes to administer and involves asking patients to recall three words after drawing a picture of a clock. If a patient shows no difficulties recalling the words, it is inferred that he or she does not have dementia.
