Insulin Resistance, Type 2 Diabetes Linked to Plaques Associated with Alzheimer’s Disease

26.08.2010
People with insulin resistance and type 2 diabetes appear to be at an increased risk of developing plaques in the brain that are associated with Alzheimer’s disease, according to new research published in the August 25, 2010, issue of Neurology®, the medical journal of the American Academy of Neurology.

Insulin resistance, or the stage before diabetes, happens when insulin, a hormone in the body, becomes less effective in lowering blood sugar.

“Type 2 diabetes and Alzheimer’s disease are two epidemics growing at alarming levels around the world,” said study author Kensuke Sasaki, MD, PhD, with Kyushu University in Fukuoka, Japan. “With the rising obesity rates and the fact that obesity is related to the rise in type 2 diabetes, these results are very concerning.”

The study involved 135 people with an average age of 67 from Hisayama, Japan. The participants had several diabetes glucose tests to measure blood sugar levels. They were also monitored for symptoms of Alzheimer’s disease over the next 10 to 15 years. During that time, about 16 percent developed Alzheimer’s disease.

After the participants died, researchers examined their autopsied brains for the physical signs of Alzheimer’s disease, called plaques and tangles. While 16 percent had symptoms of Alzheimer’s disease while alive, a total of 65 percent had plaques.

The study found that people who had abnormal results on three tests of blood sugar control had an increased risk of developing plaques. Plaques were found in 72 percent of people with insulin resistance and 62 percent of people with no indication of insulin resistance. However, the study did not find a link between diabetes factors and tangles in the brain.

“Further studies are needed to determine if insulin resistance is a cause of the development of these plaques,” said Sasaki. “It’s possible that by controlling or preventing diabetes, we might also be helping to prevent Alzheimer’s disease.”

The American Academy of Neurology, an association of more than 22,000 neurologists and neuroscience professionals, is dedicated to promoting the highest quality patient-centered neurologic care. A neurologist is a doctor with specialized training in diagnosing, treating and managing disorders of the brain and nervous system such as epilepsy, dystonia, migraine, Huntington’s disease, and dementia.

Im Focus: Neutron star merger directly observed for the first time

University of Maryland researchers contribute to historic detection of gravitational waves and light created by event

On August 17, 2017, at 12:41:04 UTC, scientists made the first direct observation of a merger between two neutron stars--the dense, collapsed cores that remain...

Im Focus: Breaking: the first light from two neutron stars merging

Seven new papers describe the first-ever detection of light from a gravitational wave source. The event, caused by two neutron stars colliding and merging together, was dubbed GW170817 because it sent ripples through space-time that reached Earth on 2017 August 17. Around the world, hundreds of excited astronomers mobilized quickly and were able to observe the event using numerous telescopes, providing a wealth of new data.

Previous detections of gravitational waves have all involved the merger of two black holes, a feat that won the 2017 Nobel Prize in Physics earlier this month....

Im Focus: Smart sensors for efficient processes

Material defects in end products can quickly result in failures in many areas of industry, and have a massive impact on the safe use of their products. This is why, in the field of quality assurance, intelligent, nondestructive sensor systems play a key role. They allow testing components and parts in a rapid and cost-efficient manner without destroying the actual product or changing its surface. Experts from the Fraunhofer IZFP in Saarbrücken will be presenting two exhibits at the Blechexpo in Stuttgart from 7–10 November 2017 that allow fast, reliable, and automated characterization of materials and detection of defects (Hall 5, Booth 5306).

When quality testing uses time-consuming destructive test methods, it can result in enormous costs due to damaging or destroying the products. And given that...

Using a new cooling technique MPQ scientists succeed at observing collisions in a dense beam of cold and slow dipolar molecules.

How do chemical reactions proceed at extremely low temperatures? The answer requires the investigation of molecular samples that are cold, dense, and slow at...

Scientists from the Max Planck Institute of Quantum Optics, using high precision laser spectroscopy of atomic hydrogen, confirm the surprisingly small value of the proton radius determined from muonic hydrogen.

It was one of the breakthroughs of the year 2010: Laser spectroscopy of muonic hydrogen resulted in a value for the proton charge radius that was significantly...
