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.

One possibly 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.

The researchers 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.

While it is true that diabetes' largest impact can be on a person's cardiovascular and metabolic systems, it has been found that there are also significant risks to a person's mental state, particularly regarding cognitive ability. With the number of diabetic children increasing, these findings put into question whether or not the aforementioned children can keep up with the demands of society and the educational system.
