Type 2 diabetes is a disease affecting more than 4 million people in our country. It has been known for some time that this type of diabetes is a greater risk of suffering a disease, such as dementia and even a reduction in the hippocampus. It was also known that people with diabetes could suffer from atrophy of the brain, but it was not known whether this was longer in the long run than in other people or if the cause of cognitive loss was.
Now new studies have found that elderly people with type 2 diabetes – even if they do not have dementia – also have a greater memory loss and verbal fluid than those who do not have diabetes more than five years. In addition, these researchers found that this loss does not seem to be related to brain atrophy.
To carry out this study, researchers There were 705 people involved, all without the history of dementia and with an age between 55 and 90 years. Of these 705 people, 348 are patients with type 2 diabetes with an average age of 68 years. The other 357 did not have diabetes, and their average age was 72 years. Both groups had magnetic resonance imaging to measure brain volume and control atrophy of the brain. In addition, psychoneuronal measures were carried out to check their cognitive status. Both tests were carried out on three different occasions in almost five years.
Researchers also controlled variables such as gender, age, educational level, cardiovascular factors, previous heartbeats, smoking history, cholesterol levels, and even body weight, so the results were taken into account by these variables. Results obtained that there is an important link between the suffering of type 2 diabetes and memory loss and verbal fluid.
Although no differences in the degree of cerebral atrophy have been detected in patients – patients with diabetes have begun an investigation with slightly higher atrophies, which in the last five years – have been observed to be ill with diabetes, even improved their verbal liquid, while patients with diabetes significantly deteriorated.
This suggests to research authors that brain atrophy is not associated with cognitive loss. What follows their results is that atrophy will occur earlier in people with diabetes, despite the fact that, when aging, they are equated with the general population. In any case, The risks to our cognitive abilities when suffering from type 2 diabetes are increasingly evident for science and another good reason to take care of our diet and exercise physical activity.
