Addressing sleep disorders after traumatic brain injury

Disorders of sleep are some of the most common problems experienced by patients after traumatic brain injury (TBI). It is important to recognize and treat these problems early to allow for optimal cognitive recovery, but because they are so common, the importance of treating them is often underestimated. In this special issue of NeuroRehabilitation scientists

Prolonged Brain Connections Seen in Adults With Autism

THURSDAY, Nov. 29, 2018 — Connections between different areas of the brain are sustained longer than usual in people with autism, perhaps explaining some of their symptoms, a new study suggests. It’s possible these prolonged connections make it difficult for the brain to switch from one activity to another, the researchers said. “People with autism

Effective new target for mood-boosting brain stimulation found

Researchers have found an effective target in the brain for electrical stimulation to improve mood in people suffering from depression. As reported in the journal Current Biology on November 29, stimulation of a brain region called the lateral orbitofrontal cortex (OFC) reliably produced acute improvement in mood in patients who suffered from depression at the

Do cancer treatments accelerate brain aging?

Previously on Medical News Today, we covered a study explaining that an experience called chemo brain affects many people undergoing cancer — particularly breast cancer — treatment. Chemo brain occurs during cancer treatment, and it may last for a long time after the treatment is over. People experiencing it report a loss of quality in

New brain region ‘could be what makes humans unique’

Due to technological advancements in recent years, medical science has made huge leaps — many with vast implications for medical and neuroscientific research. For instance, scientists devised an innovative method that allowed them to record a million neurons at once, as well as to decode neural activity in real time. The techniques gave researchers access

Low-protein high-carb diet shows promise for healthy brain aging

Low-protein high-carbohydrate diets may be the key to longevity, and healthy brain ageing in particular, according to a new mice study from the University of Sydney. Published today in Cell Reports, the research from the University’s Charles Perkins Centre shows improvements in overall health and brain health, as well as learning and memory in mice

Brain signature of depressed mood unveiled in new study

Most of us have had moments when we’re feeling down—maybe we can’t stop thinking about our worst mistakes, or our most embarrassing memories—but for some, these poor mood states can be relentless and even debilitating. Now, new research from UC San Francisco has identified a common pattern of brain activity that may be behind those

Stressed out? Study reveals it may affect your memory

Stress in middle age can make your brain shrink and make your memory worse, Harvard study finds The brain-reducing effects of stress were found to be triggered by cortisol The Harvard Medical School study was published in the journal Neurology Scientists have said ‘it’s important for people to find ways to reduce stress’  Stress in

Stimulating deeper insights into brain function

Modeling changes in brain activity over time provides deeper insights into learning and behavioral responses. Observing the brain’s response to repeated stimuli has helped KAUST researchers develop a method for modeling connectivity patterns in neural networks. Mapping connectivity patterns will help to better understand brain function, ultimately improving diagnosis and treatment of brain diseases and

How the grid cell system of the brain maps mental spaces

It has long been known that so-called place cells in the human hippocampus are responsible for coding one’s position in space. A related type of brain cell, called grid cells, encodes a variety of positions that are evenly distributed across space. This results in a kind of honeycomb pattern tiling the space. The cells exhibiting

Two seemingly opposing forces in the brain actually cooperate to enhance memory formation

The brain allows organisms to learn and adapt to their surroundings. It does this by literally changing the connections, or synapses, between neurons, strengthening meaningful patterns of neural activity in order to store information. The existence of this process—brain plasticity—has been known for some time. But actually, there are two different types of brain plasticity

New study finds thalamus wakes the brain during development

Consciousness requires continuous, internally generated activity in the brain. The modulation of this activity is the basis of the electroencephalogram (EEG) and of generation of sleep, dreams, and perception. Achieving such activity is thus an important milestone in normal brain maturation, which occurs around birth. Successful transition to this activity indicates a good prognosis for

Olfactory cells may act as ‘Trojan horse,’ carry anticancer therapy to deadly brain tumors

A special type of cell essential to the ability of olfactory neurons to regenerate may be genetically engineered to deliver anticancer therapy to the dangerous brain tumors called glioblastomas. In their report published in the Journal of the National Cancer Institute, Massachusetts General Hospital (MGH) researchers describe using olfactory ensheathing cells to deliver an anticancer
