WINSTON-SALEM, N.C. Magnetic resonance spectroscopy (MRS) may provide a noninvasive way to monitor neuropsychiatric symptoms in patients with lupus, according to results from research in mice at Wake Forest University School of Medicine. "This study is the first to demonstrate that MRS is a feasible m...Alzheimer's alarm over anesthetics
