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

Georgia student credits God for surviving brain injury: ‘Medical science can't explain my recovery’

Cole Burton, a 21-year-old Auburn University student, has made a miraculous recovery that his doctors say can only be explained by God’s intervention. (WAGA) A 21-year-old Auburn University student who suffered a traumatic brain injury has made a miraculous recovery that medical professionals are crediting to God. "My doctors have told me medical science can't explain my

How the brain fights off fears that return to haunt us

Neuroscientists at The University of Texas at Austin have discovered a group of cells in the brain that are responsible when a frightening memory re-emerges unexpectedly, like Michael Myers in every “Halloween” movie. The finding could lead to new recommendations about when and how often certain therapies are deployed for the treatment of anxiety, phobias

Helping infants survive brain cancer

Choroid plexus carcinoma (CPC) is a particularly challenging type of brain cancer. The tumor most commonly arises in infants under the age of one—who are too young to undergo radiation treatment. Only 40 percent of children remain alive five years after diagnosis, and those who do survive often suffer devastating long-term damage from the treatment.

How the brain ‘mentalizes’ cooperation

What parts of your brain are involved in gauging a friend’s actions and adjusting your own; for example, when you both carry a couch up a flight of stairs? Researchers in Japan have found that part of the right side of the brain, called the temporoparietal junction, is significantly activated when two people cooperate together

Exercise adds up to big brain boosts

Anyone who trains for a marathon knows that individual running workouts add up over time to yield a big improvement in physical fitness. So, it should not be surprising that the cognitive benefits from workouts also accumulate to yield long-term cognitive gains. Yet, until now, there was has been little research to describe and support
