High Estrogen Levels, Diabetes Together May Increase Dementia Risk 14-Fold in Older Women

30.01.2014
Older women who have high estrogen levels and diabetes may have a 14 times increased risk of dementia, according to a new study published in the January 29, 2014, online issue of Neurology®, the medical journal of the American Academy of Neurology.

Blood estrogens were measured in women free of dementia aged 65 or older. After a four-year follow-up, 543 women who did not have dementia were compared with 132 women who had dementia. Scientists looked at a number of risk factors for dementia, including diabetes, high blood pressure, abnormal blood clotting and other heart health risk factors.

The study found that the risk of dementia more than doubled for women who had high estrogen levels after accounting for other dementia risk factors. For those who had high estrogen levels and diabetes, the risk for dementia increased dramatically, by 14 times.

Estrogen levels were about 70 percent higher in women with diabetes who also had dementia compared to those without dementia. No other heart health risk factors raised the dementia risk.

“These results are surprising, given the expected brain protective effects of estrogen-based therapy,” said study author Pierre-Yves Scarabin, MD, with the French National Institute of Health and Medical Research (INSERM) in Villejuif, France. “However, more and more evidence suggests an association between high estradiol levels and dementia in women who have undergone menopause. Considering the expected increase in the number of elderly people with diabetes and dementia, more research on this topic should be urgently conducted.”

The research was supported by INSERM, the Victor Segalen-Bordeaux II University, Sanofi-Aventis, Foundation for Medical Research, National Health Fund for Employees, Directorate General of Health, MGEN, Institute of Longevity, Regional Councils of Aquitaine and Bourgogne, Foundation of France, and the National Agency of Research.

The American Academy of Neurology, an association of more than 27,000 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 Alzheimer’s disease, stroke, migraine, multiple sclerosis, brain injury, Parkinson’s disease and epilepsy.

Im Focus: Significantly more productivity in USP lasers

In recent years, lasers with ultrashort pulses (USP) down to the femtosecond range have become established on an industrial scale. They could advance some applications with the much-lauded “cold ablation” – if that meant they would then achieve more throughput. A new generation of process engineering that will address this issue in particular will be discussed at the “4th UKP Workshop – Ultrafast Laser Technology” in April 2017.

Even back in the 1990s, scientists were comparing materials processing with nanosecond, picosecond and femtosesecond pulses. The result was surprising:...

Im Focus: Shape matters when light meets atom

Mapping the interaction of a single atom with a single photon may inform design of quantum devices

Have you ever wondered how you see the world? Vision is about photons of light, which are packets of energy, interacting with the atoms or molecules in what...

Im Focus: Novel silicon etching technique crafts 3-D gradient refractive index micro-optics

A multi-institutional research collaboration has created a novel approach for fabricating three-dimensional micro-optics through the shape-defined formation of porous silicon (PSi), with broad impacts in integrated optoelectronics, imaging, and photovoltaics.

Working with colleagues at Stanford and The Dow Chemical Company, researchers at the University of Illinois at Urbana-Champaign fabricated 3-D birefringent...

Im Focus: Quantum Particles Form Droplets

In experiments with magnetic atoms conducted at extremely low temperatures, scientists have demonstrated a unique phase of matter: The atoms form a new type of quantum liquid or quantum droplet state. These so called quantum droplets may preserve their form in absence of external confinement because of quantum effects. The joint team of experimental physicists from Innsbruck and theoretical physicists from Hannover report on their findings in the journal Physical Review X.

“Our Quantum droplets are in the gas phase but they still drop like a rock,” explains experimental physicist Francesca Ferlaino when talking about the...

Im Focus: MADMAX: Max Planck Institute for Physics takes up axion research

The Max Planck Institute for Physics (MPP) is opening up a new research field. A workshop from November 21 - 22, 2016 will mark the start of activities for an innovative axion experiment. Axions are still only purely hypothetical particles. Their detection could solve two fundamental problems in particle physics: What dark matter consists of and why it has not yet been possible to directly observe a CP violation for the strong interaction.

The “MADMAX” project is the MPP’s commitment to axion research. Axions are so far only a theoretical prediction and are difficult to detect: on the one hand,...
