Many cases of autism spectrum disorders (ASDs) may result from problems in immune cells that normally work to trim back unneeded brain connections in early life, suggests a new study led by scientists at Scripps Research. The study[1] examined the effects of a set of gene mutations that account for a small percentage of autism… Read more

The Centers for Disease Control and Prevention estimates that 40 million Americans have varying levels of Toxoplasma infection, although most cases are asymptomatic. Commonly passed to humans via exposure to farm animals, infected cat litter, or undercooked meat, the parasitic infection causes unnoticeable or mild, to flu-like symptoms in most healthy people. But for a… Read more

Though many negative repercussions of human immunodeficiency virus infection can be mitigated with the use of antiretroviral therapy (ART), one area where medical advances haven’t made as much progress is in the reduction of cognitive impacts. Half of HIV patients have HIV-associated neurocognitive disorders (HAND), which can manifest in a variety of ways, from forgetfulness… Read more

Exposure to light pulsing at 40 hertz — 40 beats per second — causes brains to release a surge of signaling chemicals that may help fight Alzheimer’s Disease, Georgia Tech researchers have discovered. Though conducted on healthy mice, the study directly connects to human trials, in which researchers exposed Alzheimer’s patients to 40 Hz light… Read more

A new lineage of specialized brain cells, called Hoxb8-lineage microglia, has been investigated in a study by University of Utah scientists. They established a link between the lineage and obsessive compulsive disorder and anxiety in mice. “More women than men experience debilitating anxiety at some point in their lives. Scientists want help these people to… Read more
