Healthy Lifestyle Reduces Dementia Risk in Diabetics

New research suggests that individuals with type 2 diabetes can significantly reduce their genetic risk of developing dementia by adopting a heart-healthy lifestyle. The findings, to be presented at an American Heart Association meeting, highlight the importance of the AHA's 'Lifes Essential 8' health metrics.

These include key behaviors such as eating better, being more active, quitting tobacco, and getting healthy sleep, alongside managing weight, cholesterol, blood sugar, and blood pressure. The study analyzed over 40,000 adults with type 2 diabetes from the UK Biobank over thirteen years.

Among these participants, 840 developed mild cognitive impairment, and 1,013 were diagnosed with dementia. Those with moderate or high cardiovascular health had a 15 percent lower risk of both mild cognitive impairment and dementia compared to individuals with low cardiovascular health.

The study found an even stronger protective effect among those with a high genetic risk for dementia. Participants in this group who maintained moderate or high cardiovascular health scores were 27 percent less likely to develop mild cognitive impairment and 23 percent less likely to develop dementia.

This suggests that genetic predisposition does not determine one's fate regarding cognitive decline. As study author Yilin Yoshida noted, controlling risk factors associated with type 2 diabetes, such as obesity and high blood pressure, benefits both cardiovascular and brain health.

Dr. Hugo Aparicio, a neurologist, emphasized the interconnectedness of heart and brain health, stating that what is good for the heart is also good for the brain. The findings offer a powerful message: for those with type 2 diabetes, committing to the 'Lifes Essential 8' can lead to a longer life with maintained cognitive function and independence.

However, it's essential to note that these findings are preliminary and will require peer-reviewed publication for validation. This research underscores the critical role of lifestyle choices in mitigating neurological risks, especially for vulnerable populations like those with type 2 diabetes.

As such, the message is clear: adopting healthy habits can substantially protect brain health, even when genetic risks are present. Sources indicate that these lifestyle changes not only improve physical health but also enhance the quality of life for individuals facing cognitive decline.

With millions affected by type 2 diabetes, these findings may be pivotal in shaping future prevention strategies against dementia.
