Diabetes has unexpected effects on brain health.

Researchers from Michigan Medicine completed an intriguing study on how long-term type 2 diabetes impacts brain anatomy and function.


This study of 51 middle-aged Pima American Indians with type 2 diabetes employed Magnetic Resonance Imaging (MRI) to provide a closer look at the brain's complexity, as well as assessments of memory and language skills.

The findings revealed significant alterations in the brains of people with long-term type 2 diabetes.

Notably, the brain's outer layer was thinner, there was less grey matter, and there were more white spots—all of which indicate brain damage.

However, in a surprising twist, these structural changes were not associated with a deterioration in memory or language ability among the subjects.


Their cognitive function was comparable to that of persons without diabetes.

Evan Reynolds, a primary researcher in the study, emphasized the significance of the findings. Although the subjects' cognitive abilities looked unaltered, the physical changes observed in the brain were profound.

This implies that, even if diabetic individuals do not currently have cognitive problems, they should be constantly watched for any future alterations in brain health.

Furthermore, the study found that additional diabetes-related health conditions, such as renal and nerve disorders, were associated with similar brain abnormalities.

Interestingly, the study found that while peripheral nerve damage is widespread in diabetics, it had no direct impact on their cognitive test results.

Eva Feldman, a senior researcher on the team, emphasized the significance of raising general awareness about the possible threats diabetes poses to brain health. She emphasizes the importance of understanding these risks in order to better manage and maybe mitigate them.

The study was conducted by a team of experts from Michigan Medicine, Mayo Clinic, Monash University, and the National Institute of Diabetes and Digestive and Kidney Diseases, with funding from Novo Nordisk, the American Academy of Neurology, and the National Institute on Ageing.

While the findings are based on the authors' interpretations and are independent of the supporting organizations, they represent a significant step forward in comprehending diabetes's impacts beyond those that are well known.

The study, published in the Annals of Clinical and Translational Neurology, encourages more research into the complex effects of diabetes on health.

This study emphasizes the necessity of seeing diabetes from several angles. It is important to examine the larger consequences for general health, including brain function, in addition to regulating blood sugar levels.

As research uncovers more about diabetes, it gives essential insights that assist enhance our methods to treatment and management, resulting in a more thorough understanding of this common ailment.

Cutting calories may reduce cellular ageing and increase lifetime.

State College, Pennsylvania — Penn State researchers are presenting fresh persuasive data linking diets to ageing. Their study focused on telomeres, the genetic "end caps" that protect our chromosomes, and how calorie restriction impacts them. The scientists studied data from a two-year trial of caloric restriction in humans and published their findings in the journal Ageing Cell. They discovered that those who restricted their calories lost telomeres at different rates than the control group. Despite this, both groups concluded the research with roughly identical telomere lengths. Previous research found that reducing calories by 20 to 60 percent resulted in prolonged life for a variety of species. When a person's cells split, some telomeres are lost as chromosomes are copied to a new cell. The cell's telomeres are then shortened in total. The telomere cap eventually disappears as cells divide. The genetic information on the chromosome becomes more vulnerable to de...

DUI without alcohol? A rare syndrome in the intestines may be the culprit.

  Imagine you are a police officer. You see a car swerving all over the road. You pull over the driver, and they are plainly inebriated. They insist, with slurred speech, that they haven't consumed any alcohol all day. Do you believe them? In 2024, a Belgian man was acquitted after being arrested three times for DUI in four years. Though his position at a brewery raised suspicions, he asserted that he had not been drinking. Three doctors confirmed that he had auto-brewery syndrome and was ignorant. People with this illness have microorganisms in their intestines that produce abnormally high levels of alcohol when they break down sugars and carbs. Though it is an uncommon condition, a lady was acquitted of a DUI conviction in 2016 after being diagnosed with the same syndrome. Her blood alcohol level was four times the legal limit. I am a microbiologist who is fascinated by how the gut microbiome influences human health. As the author of the book "Pleased to Meet Me: Genes, G...

A study reveals serious side effects from common dementia medications.

Several antipsychotic medications used to treat dementia patients have been linked to dangerous side effects such as heart failure, according to a study released Thursday. A study published in the British Medical Journal (BMJ) found that using antipsychotics in persons with dementia can lead to major adverse outcomes such as stroke, blood clots, heart attack, heart failure, fracture, pneumonia, and acute kidney injury. Scientists discovered that the greatest hazards arise when therapy begins, "underscoring the need for increased caution in the early stages of treatment". Risperidone, quetiapine, haloperidol, and olanzapine are common antipsychotic medications used to treat psychotic illnesses such as schizophrenia. They are also used to treat depression that has proven resistant to other drugs, as well as those suffering from dementia, such as Alzheimer's disease. Antipsychotics are not designed to heal these conditions, but rather to alleviate certain symptoms such ...
