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.
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.
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.
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.
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.

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.
The most common cause of death among Alzheimer's patients is aspiration pneumonia. This happens when, due to difficulty in swallowing caused by the disease, an individual inadvertently inhales food particles, liquid, or even gastric fluids.
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.
Stay mentally and socially active. 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.
Some of the more common triggers for dementia like a change in environment, having personal space invaded, or being emotionally overwhelmed may be easier to handle if you mentally practice your response before you react.
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 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.
Signs of the final stages of dementia include some of the following: Being unable to move around on one's own. Being unable to speak or make oneself understood. Eating problems such as difficulty swallowing.
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.
Aggression usually starts in the mid-stage of dementia. This is the time when other behaviours, such as hoarding wandering, and compulsive behaviour are also prone to develop. In most types of dementia, the aggressive symptoms occur when the patient becomes more dependent with daily activities.
Sleeping more and more is a common feature of later-stage dementia. As the disease progresses, the damage to a person's brain becomes more extensive and they gradually become weaker and frailer over time.
People with dementia think about the same things that any human thinks about — emotions, relationships, daily life, tasks to accomplish, and more. However, dementia can change how you interact with the world because of its physical, mental, and emotional effects.
Dementia progresses differently in each person; some may progress through each stage quickly after diagnosis, and others may keep their independence for years. The early stage of dementia may last about 2 years.
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.
