It is no secret
that diabetics can often have problems with their memory and cognitive
abilities. Scientists have long speculated that blood sugar levels have
an effect on the brain's ability to process the signals that regulate
memory creation and retention. Researchers have recently found that
spikes in blood sugar levels take a genuine toll on a person's memory,
because it affects the dentate gyrus - a part of the brain that is
reported to have a role in the formation of memories.
The team said
that the effects were visible when glucose in the blood become moderately
elevated. It is assumed that this might help explain why there is a
decline in cognitive abilities as a person ages, since the ability to
properly regulate glucose in the blood worsens as a person ages.
conclusion from the data is that this is an underlying event and is
related to how the body ages, which means that age-related cognitive
decline is going to affect everyone. However, the research team has
suggested that it may be counteracted - or the impact of it lessened
- by engaging in habits and activities that help the body regulate
glucose levels. One suggestion made by the team was regular physical
exercise, as physical activity helps glucose regulation.
noted that the findings were quite compelling, and that it could have
serious implications for the current projections regarding overweight
people and diabetes rates. With the number of children and teens becoming
overweight, diabetic, or both on the rise annually, the research team
is hoping that their discovery could be of some use, particularly since
people tend to consider the consequences of diabetes on the body and
neglect the mental damage it could do.
