Dementia life expectancy is expanding each year as science and medical professionals discover new techniques in managing the disease. Furthermore, dementia is classified as a "life-limiting" disorder as a result of its progression.
Despite estimating life expectancy being incredibly challenging, it might help people plan for future care. According to a report from Age Space, instead of focusing on how much time is left, try to concentrate on how to make the most of it.
A recent statistical model could now help solve this problem as well as aid in financial planning and medical care decisions. This study was recently published in JAMA Internal Medicine on Sept. 26, 2022.
"This model estimates an individual's risk of [dying] by having a clinician input various characteristics of their dementia patient, such as age at dementia diagnosis, body mass index, dependencies in activities of daily living, and [other diseases and conditions]," study author Dr. W. James Deardorff explained. He works as a geriatrician at the University of California, San Francisco, and the San Francisco VA Health Care System.
The Statistical Research Claims
The research claims in the abstract that they found that 81% of roughly 4,300 patients with possible dementia (average age 82) who did not reside in a nursing home at the start died within the 10-year follow-up period. For almost 75% of cases, the new model anticipated who might live and who would die, but the approach clarified that it was not supposed to estimate the likelihood of dying in the near future.The scientists also produced a dementia risk calculator, which is accessible online at ePrognosis.
Statistical research in the US from PRB.org states that dementia is more common as people get older. In 2019, nearly 3% of people aged 70 to 74 had dementia, compared to 22% of adults aged 85 to 89 and 33% of adults over the age of 90 and older. Women are a little more inclined than men to get dementia. In 2019, 11% of women and 8% of men aged 70 and older had dementia.
Non-Hispanic white adults have a lower risk of developing dementia compared to most other racial and ethnic groupings. In 2019, an estimated 8.5% of non-Hispanic white adults aged 70 and older had dementia, compared to 16.1% of non-Hispanic Black adults and 16.4% of Hispanic adults.
Life Expectancy of Dementia Patients
Age, male sex, low weight (BMI less than 18.5), current or previous smoking status, chronic diseases, poor mobility, and conducting of daily-living activities, such as grocery shopping, were the factors that most strongly predicted the probability of death throughout the study. These findings were verified in a separate group of people partaking in the National Health and Aging Trends Study.
Deardorff stated that it is not an easy conversation to have but it is critical.
"A doctor can ask their patient and family if they want to hear this information," he said. "This may serve as a starting point for discussing overall treatment choices."
He added that knowing statistics about the mortality rate can help families plan for the future. "It can help professionals engage with patients and families about medical decisions, including whether to continue cancer screening or how aggressively to treat chronic illnesses like high blood pressure and diabetes," he continued.
These insights could also effectively aid financial negotiations, as several persons with dementia will require extra resources at home and may eventually be referred to healthcare institutions, Deardoff explained.
He emphasized that these estimations are just one variable in decision-making for older persons with dementia that must be looked at in the context of patient and family preferences and goals.
