Diabetes Linked to 60% Higher Dementia Risk in New Study

New research suggests a strong link between diabetes and dementia. People with diabetes face a 60% higher risk of developing the condition compared to those without it. This connection has led scientists to explore how blood sugar control affects brain health. Insulin resistance disrupts the brain’s ability to process glucose. This impairment can harm memory and has been called 'type 3 diabetes' by some experts. Over time, poor glucose metabolism may speed up age-related brain changes.

Recurrent low blood sugar episodes have also been tied to cognitive decline. These fluctuations can damage brain function and worsen memory problems.

Researchers are now testing medications that improve insulin sensitivity and reduce inflammation. Early results indicate these drugs could slow brain ageing and lower dementia risk. The findings highlight the importance of managing blood sugar levels for brain health. Better control of diabetes may help prevent cognitive decline. New treatments could offer additional protection against dementia.
