Dementia can happen to anybody, but the risk increases with age. It depends on a combination of age, genes, health and lifestyle. Over the age of 65, dementia affects almost one person in 10. Over the age of 85, dementia affects three people in 10.
Age. The biggest risk factor for dementia is ageing. This means as a person gets older, their risk of developing dementia increases a lot. For people aged between 65 and 69, around 2 in every 100 people have dementia.
Dementia affects millions of people and is more common as people grow older (about one-third of all people age 85 or older may have some form of dementia) but it is not a normal part of aging. Many people live into their 90s and beyond without any signs of dementia.
Alzheimer's disease accounts for 60-80% of cases. Vascular dementia, which occurs because of microscopic bleeding and blood vessel blockage in the brain, is the second most common cause of dementia. Those who experience the brain changes of multiple types of dementia simultaneously have mixed dementia.
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.
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.
The average life expectancy figures for the most common types of dementia are as follows: Alzheimer's disease – around eight to 10 years. Life expectancy is less if the person is diagnosed in their 80s or 90s. A few people with Alzheimer's live for longer, sometimes for 15 or even 20 years.
Studies show that dementia risk is lowest in people who have several healthy behaviours in mid-life (aged 40–65). These behaviours include: ∎regular mental, physical and social activity ∎not smoking ∎drinking alcohol only in moderation ∎keeping a healthy diet.
Abstract. 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.
There is currently no cure for most types of dementia – including the dementia caused by Alzheimer's disease. These types of dementia are what we call “neurodegenerative.” The progression of these dementias cannot be reversed right now; symptoms gradually get worse.
other long-term health problems – dementia tends to progress more quickly if the person is living with other conditions, such as heart disease, diabetes or high blood pressure, particularly if these are not well-managed.
Anxiety has been linked to shortened telomeres, accelerating aging. No matter the specific cause, anxiety is linked to an increased risk of developing dementia, especially in older ages.
-Being startled by a loud noise or by loud voices. -When an environment is too hot or too cold to get comfortable i. -Feeling demeaned or disrespected by friends, family, or caregivers. -Low self-esteem caused by an inability to communicate and care for themselves.
Chronic stress and anxiety can lead to structural degeneration and decreased functionality of the hippocampus and the prefrontal cortex. This can increase the risk for psychiatric disorders, including depression and dementia.
Is there a genetic test for dementia? Yes. It is possible to be tested for single-gene changes and some of the risk variants linked to dementia. However, genetic testing for dementia is not always appropriate.
Mini-Mental Status Examination (MMSE)
This test is usually conducted by your doctor or specialist in their office and takes around 5 minutes to complete. The MMSE is the most common test for the screening of dementia. It assesses skills such as reading, writing, orientation and short-term memory.
Dementia vs. Alzheimer's Disease: What is the Difference? Dementia is a general term for a decline in mental ability severe enough to interfere with daily life, while Alzheimer's is a specific disease. Alzheimer's is the most common cause of dementia.
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.
The five-minute cognitive test (FCT) was designed to capture deficits in five domains of cognitive abilities, including episodic memory, language fluency, time orientation, visuospatial function, and executive function.
The Self-Administered Gerocognitive Exam, known as SAGE, is a brief, pen-and-paper cognitive assessment tool designed to detect the early signs of cognitive, memory, or thinking impairments. The test evaluates your thinking abilities. This can help your doctors understand how well your brain is functioning.
