Although there is no effective treatment or proven prevention for Alzheimer's and related dementias, in general, leading a healthy lifestyle may help address risk factors that have been associated with these diseases.
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.
As people age, mental processing becomes slower and memory becomes less reliable — a normal condition known as age-related cognitive decline. Two of the interventions recommended in the NAS report — cognitive training and physical activity — appear to have the potential to delay age-related cognitive decline.
Change in routine
People with dementia often rely on their routines as a source of comfort. A daily routine helps a person know what to expect. This means that a sudden disruption in routine may cause dementia symptoms to get worse. This is especially true if a person experiences stress.
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. Vascular dementia – around five years.
Don't correct, contradict, blame or insist. Reminders are rarely kind. They tell a person how disabled they are – over and over again. People living with dementia say and do normal things for someone with memory impairment.
For most people with Alzheimer's — those who have the late-onset variety — symptoms first appear in their mid-60s or later. When the disease develops before age 65, it's considered early-onset Alzheimer's, which can begin as early as a person's 30s, although this is rare.
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.
Some factors only slightly increase a person's risk while others make it much more likely that the person will develop the condition. For most people, the biggest risk factors for dementia are ageing and genes.
Phytochemicals
Phytochemicals found in bananas help preserve nerve tissue against neurotoxins, which deteriorate nervous tissue when exposed to its substance. This may also help in preventing neurological diseases such as Alzheimer's disease.
People who regularly eat a lot of highly processed foods and drinks like cheeseburgers, chips, fried chicken, sausage, pizza, biscuits and sugary sodas are at increased risk of developing dementia, according to a new report.
An individual's genetic heritage will play a role, as does their general, physical health. People with cardiovascular disease or diabetes, especially if they are poorly controlled, are at risk of a faster deterioration. People who are frail with low immunity and recurrent infections are also vulnerable.
Anxiety and depression can make symptoms of dementia worse — particularly symptoms that affect a person's attention, short-term memory, planning, problem-solving, and decision-making. Depression may also change behaviors, with patients becoming agitated and aggressive or experiencing problems sleeping and eating.
People often live for years with dementia. While it can be difficult to think of these diseases as terminal, they do eventually lead to death. Caregivers often experience special challenges surrounding the end of life of someone with dementia in part because the disease progression is so unpredictable.
It is quite common for a person with dementia, especially in the later stages, to spend a lot of their time sleeping – both during the day and night. This can sometimes be distressing for the person's family and friends, as they may worry that something is wrong.
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.
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.
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.
Engaging in mental or social activities may help to build up your brain's ability to cope with disease, relieve stress and improve your mood. This means doing these activities may help to delay, or even prevent, dementia from developing. Find activities you enjoy that challenge your brain, and do them regularly.
