The Later Stage Of Dementia
Understanding the signs of late-stage dementia can help ensure a person gets the right level of care and support. For example, those living with advanced dementia are especially prone to infection, constipation, and skin ulcers which can put their life in danger if treatment is delayed.
Sometimes infection and illness can lead to delirium which can cause people to become confused, resist help, and experience hallucinations. The cause of delirium requires urgent medical attention, and some people may not recover completely from the effects. Signs of late-stage dementia include
- Speaking in single words, or repeated phrases that dont make sense
- Not being able to understand what people are saying to them, or things that are happening around them
- Needing help with most daily tasks
- Eating less because they find it difficult to swallow, or have less of an appetite
- Being unable to take part in simple physical activity such as walking, standing, or sitting upright
Mortality And Life Expectancy
Using the 12-digit personal identity number assigned to each resident in Sweden, all 1,258 SATS patients were investigated with the help of the Swedish population register regarding whether they were still alive on December 31, 2012. If not, the date of death was recorded.
The probable remaining length of life for each participant according to their gender and age at baseline was obtained from Statistics Sweden, based on life tables for the periods of 1993-1997 , 1998-2002 , 2003-2007 , and 2008-2012 , depending on the individual’s year of inclusion in the SATS. The patient’s actual survival time was compared with his/her expected life span relative to the gender- and age-matched general population. This unique approach allows the estimation of the decrease in the mean number of years of life span in association with different risk factors such as age at diagnosis, APOE genotype, and stages of AD.
Study Design And Outcome Measures
The SATS patients were assessed in a well-structured follow-up program, which investigated cognitive status, global performance, and functional ability at the start of ChEI treatment, after 2 months , and semiannually for a period of 3 years. The inclusion in the SATS and the evaluations at baseline were performed immediately after AD diagnosis, followed by the initiation of ChEI therapy according to the approved product recommendations. The choice of drug agent and dose was left entirely to the physician’s discretion and professional judgment.
The age at onset of AD was estimated by the clinician based on an interview with the patient’s caregiver. Early onset was defined as an onset before 65 years of age. Cognitive assessment was performed using the MMSE, with scores ranging from 0 to 30, and a higher score indicating better function. At the start of ChEI treatment, 538 individuals were defined as having mild and 253 were defined as having moderate AD.

Stages Of Alzheimer Disease
The stages of Alzheimer disease usually follow a progressive pattern. But each person moves through the disease stages in his or her own way. Knowing these stages helps healthcare providers and family members make decisions about how to care for someone who has Alzheimer disease.
Preclinical stage. Changes in the brain begin years before a person shows any signs of the disease. This time period is called preclinical Alzheimer disease and it can last for years.
Mild, early stage. Symptoms at this stage include mild forgetfulness. This may seem like the mild forgetfulness that often comes with aging. But it may also include problems with concentration.
A person may still live independently at this stage, but may have problems:
-
Remembering a name
-
Staying organized
The person may be aware of memory lapses and their friends, family or neighbors may also notice these difficulties.
Moderate, middle stage. This is typically the longest stage, usually lasting many years. At this stage, symptoms include:
-
Increasing trouble remembering events
-
Problems learning new things
-
Trouble with planning complicated events, like a dinner
-
Trouble remembering their own name, but not details about their own life, such as address and phone number
-
Problems with reading, writing, and working with numbers
As the disease progresses, the person may:
Physical changes may occur as well. Some people have sleep problems. Wandering away from home is often a concern.
Severe, late stage. At this stage, a person:
What To Do Next After Learning What Stage Of Alzheimer’s Disease Your Loved One Is In
As mentioned, learning about the stage of Alzheimers disease that a loved one is experiencing helps provide perspective and context. This knowledge makes it easier to have conversations with doctors about the patients condition and how to approach future treatment options. Understanding the later stages of the disease also helps when planning for lifestyle changes, new equipment, and other items that may be needed. One of the other major benefits in understanding the overall progression of Alzheimers disease is preparing for future living arrangements, such a memory care community, that could become a preferred option during later stages of the disease. Because the cost of dementia care is high, families should begin planning as soon as possible following a diagnosis.

What Affects Life Expectancy In Dementia
The life expectancy of someone living with dementia depends on many factors. The type of dementia, the severity of dementia at the time of diagnosis, and the individuals age, sex, and their general health and wellbeing can all impact on the time they can live with the disease.
The key things that affect life expectancy include:
How Do You Know What Stage Of Alzheimer’s Disease A Loved One Is In
The stages of Alzheimers disease presented in this post offer a reasonable framework from which to observe symptoms and understand the progression of the disease. Since there is no medical consensus for Alzheimers stages, as there is with cancer, it is important for caregivers to be aware of the individual symptoms and situation that their patient or loved one is experiencing. While healthcare providers may refer to a patients condition as late or early stage, any specific stage is less important than the context and understanding of what this means for care going forward.

Making A Complaint About Care
If you are concerned about any aspects of the person’s care, ask the service or organisation providing the care for their complaints procedure. If, after following this procedure, you feel that your complaint has not been properly addressed, you can take the complaint further. The next steps should be explained in their complaints procedure.
Care In The Later Stages Of Dementia
There are medicines used in the early stages of dementia that manage some of the behavioural symptoms. In the later stages some of these medicines can do more harm than good causing severe side effects that can increase confusion and frailty. It also becomes harder to diagnose and manage some of the normal illnesses that older people get such as Urinary Tract Infections . UTIs can exaggerate some symptoms of dementia and increase confusion sometimes know as delirium.
Pain is also something that can be present in the later stages of dementia, but can be harder to diagnose if the person isnt able to communicate it. For all of these reasons, its important to stay vigilant when looking after someone with dementia, and to talk to the GP if you are worried about anything.
There are dementia living aids and products that can help you to care for someone living with dementia. Something like a simple dementia clock or personal alarm can make the world of difference to your life and the live of the person you care for.

Evidence That Life Expectancy Calculators For Dementia Actually Work
It turns out that the length of time a person has before needing full-time care, before moving into a care community, and before dying can all be predicted somewhat accurately. This information, though not definitive, can help families get a general understanding of how to plan for the future and what to expect as the disease progresses.
In a study conducted at the department of neurology in Columbia University, groups of people with mild Alzheimers were followed for 10 years and assessed semiannually. Data from these assessments were plugged into a complicated algorithm. The people studied were tested for the following:
Mental status score Cognition and function Motor skills Psychology and behavior Basic demographic information
Other experiments have yielded similar results. A University of Kentucky study analyzed the records of more than 1,200 people with dementia and found that it was possible to accurately predict their life expectancy. Researchers looked at many variables including family history and medical problems like high blood pressure and heart disease, and ultimately realized it came down to three things:

Do Treatments Add Time To Life Expectancy
Experts simply dont know whether treatments help a person live longer with Alzheimers disease. AD and other similar dementias progress no matter what. Treatments like medications and therapies have been conclusively shown to help manage symptoms, meaning they make it easier to live with the disease, but they do not reverse symptoms. The memory of a person with dementia who takes medications like cholinesterase inhibitors, for example, will be slightly better than the memory of someone who is not on medication. Quality of life therefore improves with treatment. This means better years with dementia, but probably not more years.

Factors That Determine Longevity
One study of 438 patients in the U.K. found that the main factors that determine how long a person lives after being diagnosed with Alzheimer’s disease are age, gender, and level of disability. Here are the main research findings:
- Women lived an average of 4.6 years after diagnosis, and men lived 4.1 years.
- People diagnosed when under age 70 lived 10.7 years compared to 3.8 years for people over 90 when diagnosed.
- Patients who were frail at the time of diagnosis did not live as long, even after adjusting for age.
- Overall, the average survival time for someone in the study diagnosed with Alzheimer’s disease or dementia was 4.5 years.

Factors That Affect Life Expectancy With Dementia
As with life expectancy in general, many factors affect the expected length of survival after a diagnosis of dementia. If we include everyone of all ages, average life expectancy is decreased by almost nine years by dementia, but this number can be further refined based on individual characteristics. For example, an individuals sex is a factor affecting survival after dementia, just as it affects life expectancy in general. At all ages, expected survival after a dementia diagnosis is about 1.5 years longer for women than for men. Scientists are researching the biological basis for this, and it may also be explained in part by differences in social norms .

Gender. Men dont live as long with Alzheimers as women. A study of more than 500 people diagnosed with Alzheimers disease between 1987 and 1996 found that women with Alzheimers live, on average, 20% longer than men. Age. Someone diagnosed at 65 lives an average of about eight years, while someone over 90 who gets a diagnosis typically lives about three-and-a-half more years. Strength of Symptoms at Diagnosis. If someone is showing especially severe dementia-related problems at the time of diagnosis, this usually leads to an earlier death. Someone who wanders, is prone to falling, and experiences urinary incontinence , will typically not live as long. A lower mini-mental state examination score at the time of diagnosis will also not live as long. Other Health Problems. A person with a history of heart problems or asthma or diabetes, for example, will not live as long as someone without those underlying issues.
Age When Diagnosis Is Determined
The age at diagnosis, too, is important because an older individual may already be frail and vulnerable to additional life-shortening accidents, diseases, or infections. Life expectancy after a diagnosis of dementia decreases with increasing age for example, an average person diagnosed with Alzheimers disease between ages 70 and 79 can expect to survive seven more years, while diagnosis after age 90 is associated with an expected survival of only 2.8 additional years.

Why Is Dementia Progressive
Dementia is not a single condition. It is caused by different physical diseases of the brain, for example Alzheimers disease, vascular dementia, DLB and FTD.
In the early stage of all types of dementia only a small part of the brain is damaged. In this stage, a person has fewer symptoms as only the abilities that depend on the damaged part of the brain are affected. These early symptoms are usually relatively minor. This is why mild dementia is used as an alternative term for the early stage.
Each type of dementia affects a different area of the brain in the early stages. This is why symptoms vary between the different types. For example, memory loss is common in early-stage Alzheimers but is very uncommon in early-stage FTD.
As dementia progresses into the middle and later stages, the symptoms of the different dementia types tend to become more similar. This is because more of the brain is affected as dementia progresses.
Over time, the disease causing the dementia spreads to other parts of the brain. This leads to more symptoms because more of the brain is unable to work properly. At the same time, already-damaged areas of the brain become even more affected, causing symptoms the person already has to get worse.
Eventually most parts of the brain are badly damaged by the disease. This causes major changes in all aspects of memory, thinking, language, emotions and behaviour, as well as physical problems.
