Lowering the Risk of Dementia for Individuals with Type 2 Diabetes: Unveiling 7 Healthy Practices
Revised Article:
Dementia ain't no walk in the park, and since it don't have a cure, people are always on the hunt for ways to lower their risk of getting it. A recent study published in Neurology found that for folks with type 2 diabetes, a few health-conscious habits could help 'em stay dementia-free.
Dementia and its triggers
Dementia is a broad term for conditions that mess with a person's memory, thinking, and reasoning. It usually gets worse over time, making everyday tasks challenging. Age and family history can't be changed, but other risk factors can be modified to reduce risk. For example, smoking, obesity, and heavy drinking are known risk factors for Alzheimer's and other dementias.
Type 2 diabetes is another risk factor for dementia, particularly the type two kind. Folks with diabetes can work with their doctors to manage their condition and improve their health. Researchers keep digging to find out how healthy lifestyle choices can improve diabetes management and lower dementia risks.
Type 2 diabetes, dementia, and lifestyle changes
Researchers examined the impact of seven healthy habits on dementia risk. While these habits helped folks with and without diabetes, they had more noticeable effects on diabetes patients. The habits included:
- Quitting smoking
- Moderate alcohol consumption
- Regular physical activity
- Eating a healthy diet
- Getting enough sleep
- Lower sedentary behavior
- Frequent social interaction
These researchers used data from U.K. Biobank, focusing on participants aged 60 or older and excluding type 1 diabetics. Participants were assigned a lifestyle score based on these habits.
The study included over 160,000 individuals, with more than 12,000 having diabetes. Researchers followed these people for an average of 12 years and found that these healthy habits were linked to a lower dementia risk. But the effects were even stronger for diabetes patients.
Dr. Yingli Lu, Ph.D., one of the study authors, told Medical News Today: "Our findings emphasize that while patients with diabetes have a higher dementia risk, adhering to an overall healthy lifestyle can significantly reduce this risk."
Researcher Jeroen Mahieu, Ph.D., added a word of caution. "The most significant finding of this study is that living a healthy lifestyle reduces the risk of dementia for diabetes patients even more than it does for non-diabetes patients. Given the higher dementia prevalence among diabetes patients, this is crucial. However, we must exercise caution when interpreting effects as causal due to the study's nature and research design."
Study limitations and future studies
While the study suggests that healthy habits can decrease dementia risk, particularly for individuals with type 2 diabetes, it wasn't perfect. Firstly, lifestyle info was self-reported, increasing the chance of errors. Secondly, data on lifestyle changes over time wasn't collected. Lastly, participants with missing data tended to have lower education and income levels, which may have impacted the results.
The study team acknowledged that they might have misclassified participants with diabetes or prediabetes as not having diabetes due to data collection methods. Unknown or unmeasured factors might also have played a role unaccounted for. Lastly, the research mostly included Caucasian participants, and future studies with more diverse populations are needed.
Despite these limitations, the study contributes to the growing understanding of how our choices affect our health. Dr. Lu concluded that "our data might have important implications for doctors and other medical professionals who treat people with diabetes. [They] should consider recommending lifestyle changes to their patients. Such changes may not only improve overall health but also contribute to the prevention or delayed onset of dementia in people with diabetes. Future studies are needed to determine how combined healthy habits benefit cognitive outcomes in diabetes and the underlying mechanisms."
Note: Regular exercise, a balanced diet, maintaining a healthy weight, quitting smoking, and managing stress are generally recommended lifestyle changes for reducing the risk of dementia. However, specific advice tailored to individuals with type 2 diabetes may be provided by medical studies.

- The study in Neurology indicates that adopting health-conscious habits can lower the risk of dementia for individuals with type 2 diabetes.
- Dementia, a condition affecting memory, thinking, and reasoning, becomes more challenging over time, making everyday tasks difficult.
- While age and family history are unalterable risk factors for dementia, others such as smoking, obesity, and heavy drinking can be modified.
- Alzheimer's and other dementias are known to be associated with the risk factor, type 2 diabetes.
- In their research, scientists investigated the impact of seven healthy habits on dementia risk, finding that these choices had more significant effects on diabetes patients.
- The seven healthy habits included quitting smoking, moderate alcohol consumption, regular physical activity, eating a healthy diet, getting enough sleep, lower sedentary behavior, and frequent social interaction.
- The study, which focused on participants aged 60 or older, found that these habits were linked to a lower dementia risk, with an even stronger correlation for diabetes patients.
- Dr. Yingli Lu, one of the study authors, stated that their findings highlight that adhering to a healthy lifestyle can significantly reduce the dementia risk for diabetes patients.
- Jeroen Mahieu, another researcher involved in the study, cautioned that while the findings are crucial, effects should not be interpreted as causal due to the study's nature and research design.
- While the study suggests that healthy habits can decrease dementia risk, it had limitations such as self-reported lifestyle information, lack of data on changes over time, and potential impact from participants with lower education and income levels.
- The study team admitted that they may have misclassified participants with diabetes or prediabetes due to data collection methods, and unaccounted-for factors might have also played a role.
- Future studies with more diverse populations are needed to further understand the benefits of combined healthy habits on cognitive outcomes for diabetes patients, as well as the mechanisms underlying these benefits. Meanwhile, professionals treating diabetes patients are encouraged to recommend healthy lifestyle changes to improve overall health and potentially delay or prevent dementia.
