Study: Women may be more susceptible to concussions due to more breakable nerve fibers

Women have smaller, more breakable nerve fibers in the brain compared to men that may make them more susceptible to concussions, suggests a new study from Penn Medicine neuroscientists published online today in the journal Experimental Neurology.

Old World monkeys could hold key to stop progression of rheumatoid arthritis

In the quest for a new and more effective treatment for rheumatoid arthritis, researchers from the Keck School of Medicine of USC looked to a primate that mostly roams the land in Asia, the Middle East and Africa.

Noninvasive brain imaging reveals surgical skills acquisition and expertise of trainees

While simulation platforms have been used to train surgeons before they enter an actual operating room (OR), few studies have evaluated how well trainees transfer those skills from the simulator to the OR.

Heavy drinkers with history of TBI do not have worse drinking behavior, study finds

Head injury, which often damages brain regions overlapping with those involved in addictive behaviors, does not worsen drinking behavior in people with heavy alcohol use, according to a new study published in Biological Psychiatry: Cognitive Neuroscience and Neuroimaging.

IUD use linked to dramatic decrease in incidence of cervical cancer

Considered a safe and highly effective contraception method, intrauterine devices (IUDs) may also be quietly offering protection against the third-most common cancer in women worldwide.

Study finds that ADHD diagnosis encompasses ‘constellation’ of different disorders

Researchers have found that patients with different types of attention-deficit/hyperactivity disorder (ADHD) have impairments in unique brain systems, indicating that there may not be a one-size-fits-all explanation for the cause of the disorder.

Healthy people with psychotic-like experiences have altered brain dynamics, study finds

Healthy people experiencing subtle symptoms observed in psychotic disorders, such as hallucinations and delusions, have altered brain dynamics, according to a new study published in Biological Psychiatry: Cognitive Neuroscience and Neuroimaging.

EPFL scientists show how TMSR affects upper-limb maps in the brains of patients with amputations

Targeted motor and sensory reinnervation (TMSR) is a surgical procedure on patients with amputations that reroutes residual limb nerves towards intact muscles and skin in order to fit them with a limb prosthesis allowing unprecedented control.

WVU neuroscientist explores need for greater rigor in mindfulness research

The mindfulness movement has grown in popularity over the past two decades, but research on its effectiveness is still catching up. According to a West Virginia University neuroscientist, increasing the precision of mindfulness research can multiply the potential benefits that meditation and similar practices impart.

New study hopes to shed light on mechanism behind epileptic and non-epileptic seizures

Seizures are a common result of traumatic brain injury, especially in military veterans. A new study funded by the DOD, Congressionally Directed Medical Research Programs, and conducted in Providence RI and Birmingham AL hopes to shed new light on the mechanism behind seizures associated with post-traumatic epilepsy and psychogenic nonepileptic seizures.

Brazilian researchers find more significant cognitive deficits among early-onset cocaine users

People who begin using cocaine during adolescence display more significant cognitive deficits than people who begin using the drug in adulthood.

USC study reveals how schizophrenia has biological effect on the entire brain

Some 40 years since CT scans first revealed abnormalities in the brains of schizophrenia patients, international scientists say the disorder is a systemic disruption to the brain's entire communication system.

Biased research samples can profoundly skew results of brain imaging studies

Any scientist who studies groups of people knows that the characteristics of the "sample" -- the group of people selected for the study -- can profoundly impact the study's findings. To produce the most accurate findings, a study group ought to be as similar as possible to the people in the larger population you want to say something about.

Patients unaware of memory loss more likely to develop Alzheimer's disease, study shows

While memory loss is an early symptom of Alzheimer's disease, its presence doesn't mean a person will develop dementia. A new study at the Centre for Addiction and Mental Health has found a clinically useful way to predict who won't develop Alzheimer's disease, based on patients' awareness of their memory problems.

Brain’s motor signals sharpen sound perception, research suggests

Whether it is dancing or just tapping one foot to the beat, we all experience how auditory signals like music can induce movement. Now new research suggests that motor signals in the brain actually sharpen sound perception, and this effect is increased when we move in rhythm with the sound.

Persistent cannabis use linked to violent behavior among young people with mental illness

A new study by researchers at the Institut en santé mentale de Montréal demonstrates that sustained used of cannabis is associated with an increase in violent behavior in young people after discharge from a psychiatric hospital.

MRI and ultrasound can detect fetal brain damage caused by Zika in utero

Clinicians managing Zika-affected pregnancies should use magnetic resonance imaging (MRI) in addition to standard ultrasound (US) because the more detailed MRI images can reveal more extensive areas of damage to the developing fetal brain, according to research presented during IDWeek 2017.

New non-invasive biomarker detects Alzheimer's disease before occurrence of first symptoms

Absence of a prefrontal activation during sensory gating of simple tones detects the Alzheimer's disease (AD) before the occurrence of the first symptoms. Sanja Josef Golubic Ph.D., physicists at the Department of Physics, Faculty of Science, University of Zagreb, reveals the high potential, absolutely non-invasive biomarker of AD pathology in a new study published in the journal Human Brain Mapping. Josef Golubic found a discrete, individual biomarker of AD with "ideal" properties.
