The study, titled "Early Evidence of Low Bone Density and Decreased Serotonergic Synthesis in the Dorsal Raphe of a … [Read More...]

Aerobic Exercise Preserves Brain Volume and Improves Cognitive Function

(Radiological Society of North America) Using a new MRI technique, researchers found that adults with mild cognitive impairment (MCI) who exercised four times a week over a six-month period experienced an increase in brain volume in specific, or local, areas of the brain, but adults who participated in aerobic exercise experienced greater gains than those who just stretched. The study will be … [Read More...]

New Imaging Technique Measures Toxicity of Proteins Associated with Alzheimer’s and Parkinson’s Diseases

(University of Cambridge) Researchers have developed a new imaging technique that makes it possible to study why proteins associated with Alzheimer’s and Parkinson’s diseases may go from harmless to toxic. The technique uses a technology called multi-dimensional super-resolution imaging that makes it possible to observe changes in the surfaces of individual protein molecules as they clump … [Read More...]

Comparing Gait Parameters Can Predict Decline in Memory and Thinking
