How Long Can People Live With Dementia – Each person will have a different experience of dementia. The speed and pattern of disease progression may vary, but the condition is progressive and will worsen over time. Unfortunately, dementia will limit a person’s lifespan; The condition has now overtaken heart disease as the leading cause of death in England and Wales.
Amnesia, confusion and communication problems are caused by brain cell damage. But the mind not only controls memory and thought; It is also the control center for the body. The progressive death of brain cells eventually causes the digestive system, lungs and heart to fail, making dementia a terminal condition.
How Long Can People Live With Dementia
Studies have shown that, on average, someone will live about ten years after being diagnosed with dementia. However, this can vary significantly between individuals, with some people living longer than twenty years, so it’s important to try not to focus on statistics and make the most of the remaining time.
How Long Do People Live After A Dementia Diagnosis?
The life expectancy of a person with dementia depends on many factors. The type of dementia, the severity of dementia at diagnosis, and the person’s age, gender, and general health and well-being can all affect the length of time someone can live with the disease.
Alzheimer’s disease is the most common cause of dementia. Abnormal proteins damage the brain. It initially affects and impairs thinking and memory and gradually causes failure of all body systems.
Alzheimer’s is usually diagnosed in the mild dementia stage when memory and planning problems begin to affect daily life. The life expectancy of a person diagnosed with Alzheimer’s is usually between 8-12 years; However, some can live long enough to be healthy and undiagnosed. In an American study, people lived from one year to 26 years after they first noted symptoms, so the variation is huge.
What’s The Life Expectancy For Someone With Dementia?
Repeated small strokes can damage the brain and lead to vascular dementia. It is the second most common cause of the disease. The pattern of disease progression differs from the gradual deterioration of Alzheimer’s disease. Symptoms may remain stable for a while, followed by a sudden worsening followed by another period of stability. This reflects times when blood clots disrupt the blood supply to the brain, causing damage.
Because stroke is associated with vascular dementia, affected individuals often have other illnesses and may have poor overall health. Research suggests that the average lifespan is about four years. However, another stroke can cause sudden or severe deterioration.
Dementia with Lewy bodies (DLB) accounts for about 7% of dementia cases. Lewy bodies are small protein deposits that affect thinking, memory and movement and are linked to both dementia and Parkinson’s disease.
Alzheimer’s Disease: The Basics
Hallucinations, sleep disturbances, and movement problems can be early features of dementia with Lewy bodies, allowing the diagnosis to be made at an earlier stage. Some research suggests that survival may be significantly shorter with this challenging condition, however, the Alzheimer’s Society says:
‘Eventually, someone with DLB may need a great deal of nursing care. How the condition progresses and the life expectancy of a person with DLB varies widely. Like a person with Alzheimer’s disease, an average person can live six to 12 years after the first symptoms.’
Frontotemporal dementia or Pick’s disease is characterized by progressive damage to the frontal and temporal lobes of the brain. This leads to personality changes, impulsivity, and speech and language problems. Although it can affect the elderly, it is most often diagnosed in younger people, between forty-five and sixty-five.
How Does Dementia Affect Everyday Life?
The average lifespan from the time symptoms first start is about eight years, but there can be dramatic differences between individuals. Sadly, dementia in the young appears to be progressing rapidly. A person diagnosed between the ages of thirty and fifty can live two years less than someone diagnosed later in life.
Talking about death and dementia is difficult and painful. The statistics can seem scary. However, each person is different. People can live well with dementia and you can still look forward to times of joy and togetherness. Professional in-home caregivers can help ease the burden on family caregivers by helping your loved one continue to live in their own home in comfort and safety.

Hometouch is one of the best companies I have worked for in the care sector! I’ve always been told I’m valuable and I feel the same way. I am delighted to be part of the HomeTouch research team Healthy lifestyles and life expectancy with and without Alzheimer’s dementia: a population-based cohort study 2022; 377 doi: https://doi.org/10.1136/-2021-068390 (published 13 April 2022) Cite this as: 2022;377:e068390 Editorial Linked Healthy lifestyles and more years of life without dementia
A healthy lifestyle score was created based on five modifiable lifestyle factors: brain-healthy diet (DASH Mediterranean Diet Intervention for Neurodegenerative Delay — Mind Diet score above 40% of cohort distribution), late-life cognitive activity (composite score above) 40%, moderate or vigorous physical activity (≥150 min/week), nonsmoking, and light to moderate alcohol consumption (women 1–15 g/day; men 1–30 g/day).
Results showed 65-year-old women with four or five health factors had a life expectancy of 24.2 years (95% confidence interval 22.8 to 25.5) and 3.1 years longer than 65-year-old women with zero or one strong factor (life expectancy 21.1 years). , 19.5 to 22.4). ) of total life expectancy at age 65 years, women with four or five healthy factors spent 10.8% (2.6 years, 2.0 to 3.3) of their remaining years with Alzheimer’s dementia, whereas women with zero or one healthy factor had 19.3% (4.1 years, 3.2 to 5.1) of the disease. with Life expectancy was 21.5 years (20.0 to 22.7) for women aged 65 without Alzheimer’s dementia and four or five healthy factors, and 17.0 years (15.5 to 18.3) for those with zero or healthy factors. Total life expectancy for 65-year-old men with four or five health factors was 23.1 years (21.4 to 25.6), which was 5.7 years longer than for 65-year-old men with zero or one health factor (life expectancy 17.4 years, 15.8 to 20.1). In total life expectancy at age 65, men with four or five healthy factors spent 6.1% (1.4 years, 0.3 to 2.0) of their remaining years with Alzheimer’s dementia, and those with zero or one healthy factor spent 12.0% (2.1 years, 0.2). . to 3.0) with disease. Life expectancy for 65-year-old men without Alzheimer’s dementia and four or five healthy factors was 21.7 years (19.7 to 24.9), and 15.3 years (13.4 to 19.1) for those with zero or one strong factor.
Will Your Dog Get Dementia? A Large New Study Offers Clues.
Conclusions A healthy lifestyle was associated with longer life expectancy in men and women, and they lived a greater proportion of their remaining years without Alzheimer’s dementia. Life expectancy estimates can help health professionals, policy makers, and stakeholders plan health care services, costs, and needs.
Prevention of Alzheimer’s dementia through lifestyle changes has gained considerable attention in recent years due to growing evidence that they help slow cognitive decline and potentially reduce the risk of Alzheimer’s dementia. % risk of Alzheimer’s dementia is low. 4 However, in addition to reducing the risk of dementia, successful modification of these lifestyle factors is also associated with increased life expectancy. And since the risk of dementia increases exponentially with age, 910 will predispose to cognitive impairment and the risk of Alzheimer’s dementia. Consequently, it may be plausible that lifestyle interventions may delay Alzheimer’s dementia later in life, but the overall prevalence and years lived with the disease may not change or may increase. If this is the case, health professionals, policy makers and stakeholders must plan adequately for future health care costs and needs.
We conducted a multistate life table analysis using data from a population-based cohort of older adults living on the South Side of Chicago, Illinois, USA to determine the influence of lifestyle factors on women and men independently living with and without Alzheimer’s dementia. . . This investigation will help us understand whether increasing life expectancy through lifestyle changes affects overall years lived with Alzheimer’s dementia over the course of a lifetime.
