Worldwide, women with dementia outnumber men 2 to 1. Brain scans tell us that the rate at which brain cells are dying in the brain is faster in women than in men. Women are more likely to live longer than men. However, although risk increases with age, dementia is caused by diseases of the brain not age alone.
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.
It mainly affects people over the age of 65. The likelihood of developing dementia increases significantly with age. One in 14 people aged over 65 has dementia. This rises to 1 in 6 for people aged over 80.
Dementia is caused by damage to or changes in the brain. Common causes of dementia are: Alzheimer's disease. This is the most common cause of dementia.
This means you can help reduce your risk of dementia by:
- eating a healthy, balanced diet.
- maintaining a healthy weight.
- exercising regularly.
- keeping alcohol within recommended limits.
- stopping smoking.
- keeping your blood pressure at a healthy level.
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.
These are the most well-known early symptoms. For example, a person may not recall recent events or may keep losing items (such as keys and glasses) around the house. Memory loss is often the first and main symptom in early Alzheimer's disease.
Overview of disease progression
The symptoms of Alzheimer's disease worsen over time, although the rate at which the disease progresses varies. On average, a person with Alzheimer's lives four to eight years after diagnosis, but can live as long as 20 years, depending on other factors.
There is currently no "cure" for dementia. In fact, because dementia is caused by different diseases it is unlikely that there will be a single cure for dementia. Research is aimed at finding cures for dementia-causing diseases, such as Alzheimer's disease, frontotemporal dementia and dementia with Lewy bodies.
Families often ask “are dementia patients aware of their condition?” In some cases, the short answer is no, they're not aware they have dementia or Alzheimer's.
Summary. The clock-drawing test is a quick way to screen for early dementia, including Alzheimer's disease. It involves drawing a clock on a piece of paper with numbers, clock hands, and a specific time. The inability to do so is a strong indication of mental decline.
A new study finds that a simple, self-administered test developed by researchers at The Ohio State University Wexner Medical Center, College of Medicine and College of Public Health can identify the early, subtle signs of dementia sooner than the most commonly used office-based standard cognitive test.
The 50% survival time in men was 4.3 years (95% CI, 2.4-6.8 years) in mild dementia, 2.8 years (95% CI, 1.5-3.5 years) in moderate dementia, and 1.4 years (95% CI, 0.7-1.8 years) in severe dementia, and in women, 5.0 years (95% CI, 4.5-6.3 years) in mild dementia, 2.8 years (95% CI, 1.8-3.8 years) in moderate dementia, ...
Leafy Green Vegetables. What is the number one food that fights dementia? Green leafy vegetables are probably the number one food that fights dementia. They have a strong, positive effect on cognitive health.
Foods for memory
Fruits, vegetables, whole grains, fish, and olive oil help improve the health of blood vessels, reducing the risk for a memory-damaging stroke. Fish are high in omega-3 fatty acids, which have been linked to lower levels of beta-amyloid proteins in the blood and better vascular health.
In the CAIDE study, coffee drinking of 3-5 cups per day at midlife was associated with a decreased risk of dementia/AD by about 65% at late-life. In conclusion, coffee drinking may be associated with a decreased risk of dementia/AD.
Researchers found that chronic stress is a significant risk factor for dementia. Because this study looked at several previous studies, its findings are particularly convincing. A study of 1,700 seniors with an average age of 77 found a link between depression—which can both cause and be caused by stress—and dementia.
It can be helpful to think of dementia progressing in three stages – early, middle and late. These are sometimes called mild, moderate and severe, because this describes how much the symptoms affect a person.
