Non-invasive electrical stimulation alters blood flow in brain tumors

In a first-of-its kind study, neurologists at Beth Israel Deaconess Medical Center (BIDMC) tested the use of non-invasive electrical stimulation as a novel therapeutic approach to brain tumors. In an experiment published in Science Advances, the scientists—led by Emiliano Santarnecchi, Ph.D., principal investigator at the Berenson-Allen Center For Non-Invasive Brain Stimulation at BIDMC—demonstrated that applying

How the brain distinguishes between voice and sound

Is the brain capable of distinguishing a voice from the specific sounds it utters? In an attempt to answer this question, researchers from the University of Geneva (UNIGE), Switzerland, – in collaboration with the University of Maastricht, the Netherlands—devised pseudo-words (words without meaning) spoken by three voices with different pitches. Their aim? To observe how

Alzheimer’s disease: Sex affects tau accumulation in the brain

The strongest genetic risk factor for Alzheimer’s disease is the apolipoprotein E type 4 allele (ApoE ε4). Research presented by Manish Paranjpe at the 2019 Annual Meeting of the Society of Nuclear Medicine and Molecular Imaging (SNMMI) used positron emission tomography (PET) to show that women who are ApoE ε4 carriers and already experiencing mild

Research reveals how the Internet may be changing the brain

An international team of researchers from Western Sydney University, Harvard University, Kings College, Oxford University and University of Manchester have found the Internet can produce both acute and sustained alterations in specific areas of cognition, which may reflect changes in the brain, affecting our attentional capacities, memory processes, and social interactions. In a first of

A comprehensive map of how Alzheimer’s affects the brain

MIT researchers have performed the first comprehensive analysis of the genes that are expressed in individual brain cells of patients with Alzheimer’s disease. The results allowed the team to identify distinctive cellular pathways that are affected in neurons and other types of brain cells. This analysis could offer many potential new drug targets for Alzheimer’s,

Researchers look back in time to prevent future brain injuries

University of Toronto researchers used a novel data-mining approach to uncover the most common medical problems affecting people in the time before they suffered a traumatic brain injury (TBI). The results can be used to better predict and prevent these life-altering incidents. Professor Michael Escobar, a biostatistician at the Dalla Lana School of Public Health,

Electrical Stimulation Makes Old Brains Act Young Again

A short session of brain zapping can reverse some of the effects of aging in older adults, a new study suggests. The technique isn't ready for non-experimental use yet, and it's not clear how long the benefits last. But the study authors said they hope that their findings will set the stage for improving cognition

This Woman's Brain Tumor Symptoms Were Dismissed as Headaches

After 15 trips to the doctor for migraines, Beckie Hiley’s symptoms were still dismissed. The UK 19-year-old spent months dealing with crippling headaches that were completely hindering her from living a normal life—she couldn’t go to work or school, and she could barely keep food down. Despite her debilitating symptoms, doctors told her her pain
