Like so many others, you may have noticed that you can’t remember like you once could. Sadly, some of your most common habits may actually increase your risk for developing dementia. Pay attention to this – life expectancy is increasing! If you don’t do anything to change, most likely you will get worse as you get older. But wait! There are changes you can make that will make a difference.
The reviewed research makes it clear that reduced memory is not a coincidence, and that you have quite a bit of control(Kerti L, et al. 2013). The study participants were 141 individuals both men and women with an average age of 62.1 years. A verbal learning test was used and their fasting HbA1c, glucose and insulin were checked. HbA1c is a measurement of long-term glucose control. MRI scans were implemented to assess hippocampal volume and micro structure.
The results were very interesting and showed that even in the absence of type 2 diabetes or impaired glucose tolerance, chronically higher blood glucose levels had a negative influence on cognition possibly due to structural changes in brain areas relevant to learning.
The researchers stated that strategies aimed at lowering glucose levels even in the normal range may beneficially influence cognition.
