Hyperactive immune system gene causes schizophrenia-like changes in mice

Excessive activity of an immune system gene previously linked to schizophrenia reproduces neural and behavioral aspects of the disease in mice, according to a new study. The finding provides mechanistic support for the importance of the gene in the dev…

Exosomes promote remarkable recovery in stroke

Scientists present brain-imaging data for a new stroke treatment that supported full recovery in swine, modeled with the same pattern of neurodegeneration as seen in humans with severe stroke.

Brain blood flow sensor discovery could aid treatments for high blood pressure and dementia

Scientists have discovered the mechanism that allows the brain to monitor its own blood supply, a finding in rats which may help to find new treatments for human conditions including hypertension (high blood pressure) and dementia.

What is the difference between anorexia and bulimia?

People with anorexia tend to severely restrict their food intake, while those with bulimia go through periods of overeating followed by unhealthful behaviors to ‘purge.’ Learn more here.

Risk of lead exposure linked to decreased brain volume in adolescents

In a study using brain scans from nearly 10 thousand adolescents across the country, investigators show that risk of lead exposure is associated with altered brain anatomy and cognitive deficits in children from low income families.

When pregnant moms are stressed out, babies’ brains suffer

Knowing that your unborn fetus has congenital heart disease causes such pronounced maternal stress, anxiety and depression that these women’s fetuses end up with impaired development in key brain regions before they are born, according to new research.

Study sheds light on link between cannabis, anxiety and stress

A molecule produced by the brain that activates the same receptors as marijuana is protective against stress by reducing anxiety-causing connections between two brain regions, researchers report.

Brain pressure controls eye pressure, revealing new avenues for glaucoma treatment

Neuroscientists have discovered that eye and brain pressure are physiologically connected.

Protein associated with ovarian cancer exacerbates neurodegeneration in Alzheimer’s

Scientists have identified a protein found in ovarian cancer that may contribute to declining brain function and Alzheimer’s disease, by combining computational methods and lab research.

Prenatal exposure to flame retardants linked to reading problems

A new study suggests that prenatal exposure to flame retardants may increase the risk of reading problems.
