Postmenopausal women at higher risk of stroke than they think

A new study by researchers at NYU Langone Medical Center and colleagues found that traditional risk factors for stroke - such as high cholesterol - are not as accurate at predicting risk in postmenopausal women as previously thought. Instead, researchers say doctors should refocus their attention on triglyceride levels to determine which women are at highest risk of suffering a devastating and potentially fatal cardiovascular event.

Scientists uncover genes that govern male and female behaviors

Hormones shape our bodies, make us fertile, excite our most basic urges, and as scientists have known for years, they govern the behaviors that separate men from women. But how? Now a team of scientists at the University of California, San Francisco (UCSF) has uncovered many genes influenced by the male and female sex hormones testosterone and estrogen that, in turn, govern several specific types of male and female behaviors in mice.

Strong link between triglyceride levels and ischemic stroke in older women

In a surprising finding with significant implications for older women, researchers at Albert Einstein College of Medicine of Yeshiva University and NYU School of Medicine have found that high levels of triglycerides (blood fats) are the strongest risk factor for the most common type of stroke in older women – more of a risk factor than elevated levels of total cholesterol or of low-density lipoprotein (LDL) cholesterol.

Abnormal tau protein propagates along linked brain circuits

For decades, researchers have debated whether Alzheimer's disease starts independently in vulnerable brain regions at different times, or if it begins in one region and then spreads to neuroanatomically connected areas. A new study by Columbia University Medical Center (CUMC) researchers strongly supports the latter, demonstrating that abnormal tau protein, a key feature of the neurofibrillary tangles seen in the brains of those with Alzheimer's, propagates along linked brain circuits, "jumping" from neuron to neuron.
