Alzheimer’s disease, what to expect? | Stages & life expectancy

Dementia is progressive. This means signs and symptoms may be relatively mild at first but they get worse with time. Dementia affects everyone differently, however it can be helpful to think of dementia progressing in ‘three stages’.

    Life Expectancy And Years Lived Without And With Dementia

    Life expectancy of women ranged from 18.0 years at age 65 to 2.3 years at age 95. Of total life expectancy at age 65, 5.7%, which corresponds to 1.0 year , was lived with dementia, increasing with age to 42.1% of life expectancy at age 95 . For men, overall life expectancy ranged from 15.6 years at age 65 to 1.8 years at age 95, of which 3.7% and 35.3% , respectively, were lived with dementia . Absolute numbers are presented in Web Table 2.

    Total life expectancy with and without dementia, Rotterdam Study, the Netherlands, 19902015. The life expectancy per year from the age of 65 years, for women and men . Bars represent the total number of years lived , segregated by years without dementia and with dementia . The solid line reflects the percentage of remaining life-years lived with dementia .

    In 3 different scenarios for preventive interventions against dementia, delaying the onset of dementia in the population by 1, 2, or 3 years resulted in reductions in the number of observed incident cases from 1,666 to 1,417, 1,154, and 886, respectively. The number of life years lived with dementia thereby decreased by 25% in the 1-year scenario, 46% in the 2-year scenario, and 57% in the 3-year scenario, broadly similar for women and men .

    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:

    age when the first symptoms appeared gender how impaired someone was when diagnosis was first made

    How To Care For Someone With Dementia

    Dementia can be a difficult time for family members and friends. The U.S Department of Health and Human Services recommends various tips and suggestions to those caring for loved ones with dementia.

    • Aim to maintain a regular routine with the person who has dementia. This can include bathing, eating, and dressing at the same time each day.
    • Plan and encourage the person to do activities they enjoy, such as dancing or another exercise.
    • Help the person maintain their independence and feel in control of their daily activities by using to-do lists, notebooks, and calendars to organize events and appointments.
    • Allow the person to feel as in charge as possible when doing activities with them.
    • Aim to be consistent and familiar at all times, such as when doing activities.
    • Avoid clothing with buttons, belts, and shoelaces opt for zips and elastic waistbands instead.
    • Respect their personal space and allow them as much control over their life as possible.
    • Surround them with familiar objects and photographs that make them feel secure.
    • Listen to concerns and frustrations without questioning or dismissing them.
    • Safety-proof their living area by removing rugs they may trip over or putting away chemicals they may mistake for something else.

    End-of-life care, also known as palliative care, aims to help the person with dementia feel as comfortable as possible during the later stages of the disease. It may last a few days or several years.

    These Us Cities Have The Worst Life Expectancy Report Finds

    Where you live has a big impact on how long you live, a recent analysis of major U.S. metro areas finds.

    While people born in Bridgeport, Connecticut, can expect to live around 83 years on average, natives of Jackson, Mississippi, have lives that are 8.6 years shorter, according to a MoneyGeek report.

    The report analyzed 119 metro areas with populations of 250,000 or more using data from the University of Wisconsin Population Health Institutes county health rankings. Researchers found the coastal lifestyle appears to be good for longevity: 6 of the top 10 metros for life expectancy are in California or Florida.

    This study isnt the first to connect location with longevity. Researchers at Stanford and MIT found that moving to the Northeast, California and parts of Florida even after age 65 could grow peoples remaining life expectancy by as much as 5 percent.

    Researchers found the areas with the least favorable effects on life expectancy are concentrated in the deep South and Southwest.

    Those results are echoed in MoneyGeeks analysis, where the bulk of metro areas with lowest life expectancies are in southern states.

    See the 25 metro areas with the lowest life expectancies in the chart below. The age refers to the average life expectancy at birth for people born in the metro area.

    What Do We Mean By Signs And Stages Of Dementia

    There are many different types of dementia and all of them are progressive. This means symptoms may be relatively mild at first but they get worse with time, usually over several years. These include problems with memory, thinking, problem-solving or language, and often changes in emotions, perception or behaviour.

    As dementia progresses, a person will need more help and, at some point, will need a lot of support with daily living. However, dementia is different for everyone, so it will vary how soon this happens and the type of support needed.

    It can be helpful to think of there being three stages of dementia:

    These are sometimes called mild, moderate and severe, because this describes how much the symptoms affect a person.

    These stages can be used to understand how dementia is likely to change over time, and to help people prepare for the future. The stages also act as a guide to when certain treatments, such as medicines for Alzheimers disease, are likely to work best.

    Making A Dementia Care Plan

    Planning for dementia care is an important step to helping you or a loved one feel prepared for the future. While no life expectancy calculator is exact, it can give you an idea of what to expect before and after your dementia diagnosis. Fortunately, there are many steps that you can take to help plan for dementia care and put your mind at ease.

    The first step is to speak with your physician and talk about your symptoms. Once you receive an official diagnosis, youll be able to plan. An early diagnosis can help you get a head start on the planning and dementia process in the event that your symptoms may worsen. You can also take this time to research and educate yourself on local and national dementia care resources, and familiarize yourself with the various stages and symptoms you might experience.

    Empowering yourself with resources is an important step to dementia care planning. Its also a good idea to plan around your support system and include them in your decisions. If youre a caregiver, its a good idea to delegate tasks and go over a care plan so that you dont experience caregiver burnout.

    A general caregiving plan can include daily tasks, housework/cleaning, medication management, and other important aspects for someone with dementia.

    Life Expectancy Following Diagnosis Of Alzheimers Disease Depends On Age At Diagnosis

    The life span of people with Alzheimers disease depends greatly on the age of the person when Alzheimers disease is diagnosed, according to a study by researchers at the Johns Hopkins Bloomberg School of Public Health. Determining the survival following a diagnosis of Alzheimers disease is important in helping patients, families, and their caregivers deal with the illness. The findings are published in the November 18, 2002, edition of Archives of Neurology.

    The duration of survival following a diagnosis of Alzheimers disease depends critically on the subjects age at diagnosis. The results of this study indicate that the median survival of patients with Alzheimers disease could range from nearly nine years for persons diagnosed at age 65 to approximately three years for persons diagnosed at age 90 years, said Ronald Brookmeyer, PhD, professor of Biostatistics at the Johns Hopkins Bloomberg School of Public Health.

    Data for the study were collected from the Baltimore Longitudinal Study of Aging, which began in 1958 to monitor the effects of aging. The participants were asked to return for follow-up visits every two years to be examined and to answer questionnaires. From this study, Dr. Brookmeyer and his colleagues selected 921 participants who were age 55 or older in 1985 and had received some follow-up visits. Alzheimers disease was diagnosed using several neuropsychological tests and deaths were recorded through September 1999.

    Mortality And Life Expectancy

    Stages and Life Expectancy of Alzheimer’s Disease | A Doctor explains

    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.

    Strengths And Limitations Of Study

    The strengths of our study are a population based design, long term follow-up, and accurate diagnosis of Alzheimers dementia through structured clinical neurological evaluations with neuropsychological testing. Our study has several limitations. Firstly, adherence to lifestyle factors was determined at baseline and not updated during the follow-up because we think that lifestyle changes could be attributed to cognitive impairment as the population ages. Secondly, the proportion of people with an unhealthy lifestyle could be underestimated in our study because people with poor health are less likely to participate in research studies , or due to their overall health, they might have died before having the opportunity to participate in our study . Thirdly, assessments of lifestyle factors were based on self-report and could be prone to measurement error, although these questionnaires were validated. Fourthly, the life expectancy estimates provided in this study should not be generalized to other populations without additional research and validation.

    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.

    Lewy Body Dementia Prognosis

    Lewy body dementia is a form of dementia characterized by the development of abnormal deposits in the brain. People with Lewy body dementia have trouble with movement as well as cognitive decline. Thinking problems generally show up before movement problems. As Lewy body dementia progresses, affected individuals may also experience visual hallucinations and sleep problems.

    Life expectancy for a person with Lewy body dementia is approximately 2 to 8 years after the onset of noticeable symptoms.

    UCSF-Led Study Suggests Model May Lead to Fewer Unnecessary Medical Interventions

    A mortality prediction model for older adults with dementia may help clinicians frame discussions with patients and their families relating to end-of-life care, such as at-home support and nursing homes. Additionally, the model may help physicians determine if the patients should continue with routine cancer screening or discontinue medications, like insulin for those with Type 2 diabetes interventions that may harm more than help.

    In their study, publishing in JAMA Internal Medicine on Sept. 26, 2022, researchers led by UC San Francisco followed 4,267 participants with probable dementia, who were not residents of nursing homes, in which 81% of them had died by the end of the follow-up period.

    A prediction model was developed based on an individuals age, sex, body mass index, chronic conditions, smoking status, ability to walk several blocks and engage in vigorous activity. They also included ability to perform activities of daily living, such as attending to personal care, eating and getting in and out of bed, as well as instrumental activities of daily living like meal preparation, grocery shopping, managing medications and money. The model proved accurate in determining who lived and who died over a period of up to 10 years in approximately 75% of cases.

    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. was developed with funding from the National Institute on Aging .
