Reducing dementia risk: the role of glycemic control in type 2 diabetes

A recent study investigated the relationship between long-term blood sugar control and the risk of dementia in older individuals with type 2 diabetes. The researchers examined data from over 250,000 participants aged 50 years or older with type 2 diabetes. They found that those who had a majority of their blood sugar levels, measured by glycated hemoglobin (HbA1c), at 9% or higher had the highest risk of developing dementia.

The study suggests that maintaining relaxed glycemic targets, meaning slightly higher blood sugar levels, may be more beneficial for older individuals with type 2 diabetes in terms of reducing the risk of dementia. Participants with more than half of their HbA1c measurements below 8% had a lower risk of dementia. These findings support the current clinical guidelines that recommend higher glycemic targets for older people with type 2 diabetes.

In summary, the study highlights the importance of glycemic control in reducing the risk of dementia among older individuals with type 2 diabetes. It suggests that maintaining blood sugar levels within certain ranges can have a significant impact on dementia risk. The results support the current recommendations for relaxed glycemic targets in older people with type 2 diabetes to promote better overall health outcomes.
