Alzheimer's disease, the most common dementia diagnosis among older adults. It is caused by changes in the brain, including abnormal buildups of proteins known as amyloid plaques and tau tangles. Frontotemporal dementia, a rare form of dementia that tends to occur in people younger than 60.
Alzheimer disease is the most common form and may contribute to 60–70% of cases. Other forms include vascular dementia, dementia with Lewy bodies (abnormal deposits of protein inside nerve cells), and a group of diseases that contribute to frontotemporal dementia (degeneration of the frontal lobe of the brain).
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.
About dementia
These changes trigger a decline in thinking skills, also known as cognitive abilities, severe enough to impair daily life and independent function. They also affect behavior, feelings and relationships. Alzheimer's disease accounts for 60-80% of cases.
Creutzfeldt-Jakob disease causes a type of dementia that gets worse unusually fast. More common causes of dementia, such as Alzheimer's, dementia with Lewy bodies and frontotemporal dementia, typically progress more slowly. Through a process scientists don't yet understand, misfolded prion protein destroys brain cells.
Rapidly progressive dementias (RPDs) are dementias that progress quickly, typically over the course of weeks to months, but sometimes up to two to three years. RPDs are rare and often difficult to diagnose. Early and accurate diagnosis is very important because many causes of RPDs can be treated.
It is important to note that dementia progresses at different speeds for every person, and for different types of dementia. The most well-known form of dementia, Alzheimer's disease, is just one specific type of dementia, and tends to have the slowest progression of all types.
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.
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 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.
One of the most common causes of death for people with dementia is pneumonia caused by an infection. A person in the later stages of dementia may have symptoms that suggest that they are close to death, but can sometimes live with these symptoms for many months.
“We know that age is the biggest risk factor for dementia and we know that Australia's population is ageing.” For people aged older than 65, the risk of developing dementia doubles every five or six years. There were 401,300 Australians with dementia in 2022, the AIHW estimated, a 4% increase from 2021.
The SAGE test is a 12-question exam that measures cognitive functioning and may help a physician determine whether Alzheimer's is present.
Frontotemporal Dementia (FTD) is less common than Alzheimer's and Vascular Dementia, but is actually the 3rd most common type of dementia for people aged under 65. The damage to the brain cells affects the frontal and temporal lobes of the brain.
We all inherit a copy of some form of APOE from each parent. Those who inherit one copy of APOE-e4 from their mother or father have an increased risk of developing Alzheimer's. Those who inherit two copies from their mother and father have an even higher risk, but not a certainty.
While there is no conclusive evidence that we can prevent the development of dementia, there is a general acknowledgement that there are some areas where poor lifestyle choices may increase the risk of developing dementia (that is, a poor diet, smoking, drinking excessive amounts of alcohol, lack of exercise, and not ...
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.
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.
Dementia is often called a 'life limiting' condition although people have been known to live with it for as long as 26 years after they first start showing symptoms. Generally speaking, the life expectancy of a person with dementia depends on the type of dementia they are diagnosed with, their age, and their health.
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.
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.
It's not uncommon for a person with dementia to experience an increase in cravings for sugary foods, leading to consumption of excessive quantities of sweets, chocolate and cakes. According to Alzheimer's Association, taste buds can diminish when the disease takes hold.
Abstract. Abnormal sweet-food craving may occur in subjects with Alzheimer's disease. This behavior may be due to abnormalities in the brain serotonin system.
