A new study looked at the relationship between a number of lifestyle characteristics and the risk of stroke, dementia, and depression in later life.
The findings indicate that leading a healthier lifestyle is associated with a decreased risk of late-life depression as well as a lower risk of stroke, dementia, and late-life depression combined.
Making healthy lifestyle choices is beneficial for brain health, which could lead to better long-term health results.
There is continuous research on the relationship between routine activities and lifestyle decisions and mental health and brain health. A topic of interest is how these lifestyle decisions impact the likelihood of depression later in life.
A study examining the relationship between brain care measures and late-life depression risk was published in Frontiers in Psychiatry.
Researchers discovered that there was a 33% lower risk of late-life depression for every five points increase in brain care ratings, which indicate healthier lifestyle choices. The data they used to analyse over 355,000 subjects.
Additionally, a 27% reduction in the risk of a composite outcome consisting of dementia, late-life depression, and stroke was linked to every five-point rise.
The findings suggest specific measures that individuals can take to lower their chance of developing age-related brain disorders.
Dr. Noah Kass, DSW, LCSW, a psychotherapist and non-study author, gave Medical News Today his perspective on the results:
The results of the study demonstrate how depression, dementia, and stroke are related to one another. It highlights how important it is to tackle brain health holistically. Changes in lifestyle that can lower the risk of these disorders can be identified by individuals and healthcare practitioners with the help of the Brain Care Score (BCS). According to this research, maintaining brain health entails treating mental health conditions like depression in addition to preventing neurodegenerative disorders like Parkinson’s and Alzheimer’s. The study’s vast dataset lends credence to its findings, which indicate a strong correlation between lifestyle factors and outcomes related to brain health.
A healthy lifestyle affects the risk of stroke, dementia, and depression.
The goal of this study was to examine the relationship between late-life depression—depression that manifests after the age of sixty—and the variables that affect brain health.
Participants with specific illnesses, such as bipolar affective disorder, manic episodes, and schizophrenia, were not accepted.
The UK Biobank provided the researchers with 363,323 patients for their study on late-life depression and 358,198 participants for their composite event cohort, which examined dementia, stroke, and late-life depression combined.
Researchers employed a brain care score to examine parameters related to brain health. The brain care score that was employed in this investigation was an adaptation of an earlier instrument designed to examine many risk factors for specific age-related brain disorders.
Physical factors considered in the brain care score include:
blood pressure
cholesterol amounts
BMI, or body mass index
It also covers social and emotional aspects like relationships, stress levels, and life purpose, as well as lifestyle aspects like sleep, diet, and alcohol consumption.
Researchers changed the nutrition section and left out the purpose of life measurement for this study, which resulted in slightly altered scoring. In this study, the highest attainable score was 19, indicating that overall, higher scores indicate greater brain health.
Researchers examined late-life depression patients and performed a subset sensitivity analysis using general practitioner data.
The subgroup analysis using general practitioner data revealed that the median follow-up time was 12.5 years, while the average brain care score for participants was 12.
According to the study’s overall findings, there was a 33% decrease in the likelihood of late-life depression for every five points higher brain care scores. For people who were younger, the outcomes were even more dramatic.
Every five points higher on the score at baseline was linked to a 59% decreased chance of late-life depression in people under 50. Researchers discovered that a 40% lower incidence of late-life depression was linked to every five-point increase in brain care ratings in their sensitivity analysis, which included data from general practitioners.
Additionally, researchers discovered that a 27% decrease in late-life depression, dementia, or stroke events was linked to every five points improvement in brain care ratings.
Further study on brain care ratings is required.
The research does have flaws, albeit the consequences.
First off, even though the UK Biobank offers valuable data, it is important to remember that the sample may not accurately reflect the entire population, therefore extra caution should be used when extrapolating the findings.
Data from participants in other nations may also be included in future studies.
Second, self-reporting by participants was a requirement for some brain care score components, which may have resulted in inaccurate information.
Furthermore, the data cannot be used to infer causation and there is a possibility of missing data, such as missed diagnoses of depression.
