Now they want to add another complication to the list of diabetes
complications. Cognition decline is now the result of poor blood
glucose management. Cognition is the mental
act or process by which knowledge is acquired, including perception,
intuition, and reasoning. I can understand this happening,
but how do they classify other people with cognition decline. Are
they people with undiagnosed diabetes? I would be guessing, but I do
believe some may have undiagnosed diabetes, but not a large number.
The study in Archives of Neurology says
that, “poor glucose control in older,
well-functioning adults with no dementia are linked to reduced
cognitive function and higher cognitive decline.”
The researchers conclude: "This
study supports the hypothesis that older adults with DM have reduced
cognitive function and that poor glycemic control may contribute to
this association. Future studies should determine if early diagnosis
and treatment of DM lessen the risk of developing cognitive
impairment and if maintaining optimal glucose control helps mitigate
the effect of DM on cognition."
Therefore, they are not saying type 2
only, but all with diabetes mellitus. The researchers from the
University of California, San Francisco and the San Francisco VA
Medical Center assessed 3069 patients and administered two tests.
The two tests were the Modified Mini-Mental State Examination (3MS)
and Digit Symbol Substitution Test (DSST). These tests were done at
the beginning of the study and repeated at selected intervals over
the 10-year period of the study. The average age of the patients was
74.2 years. Of the participants, 42% were black and 52% were female.
Of the participants, 717 had diabetes
at the beginning of the study and 2352 has no diabetes. During the
study, 159 participants developed diabetes. At the start of the
study, those with diabetes had lower 3MS and DSST test scores than
those without diabetes. At the 9-year mark, participants without
diabetes had a similar pattern of decline. Those with diabetes and
that developed diabetes, showed a marked decline in both the 3MS and
DSST tests compared to those not having diabetes.
This points out how important good
blood glucose management is for our brain health and the fact that
poor management can bring on not only many complications, but
cognitive decline as well.
