Neuroimaging

 

Head trauma and sports—most notably football but also hockey, soccer and boxing—have been the focus of plenty of media coverage. Recent studies have shown an overwhelming majority of deceased football player’s brains contained evidence of chronic traumatic encephalopathy, or CTE.

A team of Italian researchers used resting-state fMRI to examine functional connectivity abnormalities in the brain in patients with multiple sclerosis (MS). They wanted to see how abnormalities in cerebellar dentate nuclei (DNs) affect an individual’s balance, posture and muscle tone.

New research from a Spanish team of researchers used MRI to explore whether subclinical obsessive-compulsive symptoms in children could be related to the brain’s structure.

In rare cases, brain lesions can lead previously law-abiding individuals to criminal behavior. Researchers, led by Ryan Darby, MD, an assistant professor of neurology at Vanderbilt University Medical Center, examined MRI and CT scans to see if such injuries can lead to deteriorated decision-making and a disregard for morality.

A recent study published in the Journal of the American Academy of Orthopedic Surgeons (AAOS) found that females are more likely to experience sports-related concussions (SRCs) than males, narrowing the research gap of sex specific predictors of occurrence and recovery from SRCs.

Study finds physical difference in brains of earthquake survivors with PTSD

Survivors of a recent earthquake who suffer from post-traumatic stress disorder (PTSD) have greater cortical thickness and reduced volume in specific regions of their brains when compared to other survivors with no reported symptoms, according to results of a study published online March 1 in the journal Radiology.

Worth a thousand words: The neural impact of graphic warning labels on young adult smokers

Warning labels on cigarette packaging featuring graphic images have a significant impact on the brains of young adult smokers, particularly in neural regions responsible for emotion, memory and decision-making, according to results of study published on in the journal Addictive Behavior Reports.

Underappreciated brain region singled out as Alzheimer's hot spot

A new review of the literature suggests that a breakdown in the integrity of the locus coeruleus (LC), the small region of the brain that releases the key neurotransmitter norepinephrine (NE), may figure more prominently in late-onset Alzheimer’s than previously suspected.  

NEJM: ‘Cautious optimism should not become complacency’ in fight against dementia

Despite recent research and positive historical trends signaling an overall decline in instances of dementia in certain populations, persistence is needed to ensure that progress against the disease does not reverse course, according to a historical perspective published online Feb. 11 by the New England Journal of Medicine.

Can fMRI help researchers find the next great painkiller?

New research suggests that fMRI may have a role to play in evaluating the effectiveness of potential new painkillers and could allow “more effective and safer pain medications to reach patients who suffer from chronic pain sooner,” according to the American Society of Anesthesiologists.  

RSNA: Alzheimer’s study nets research award

CHICAGO—This year’s winners of the Alexander R. Margulis Award for Scientific Excellence, presented annually by the RSNA to recognize the best scientific article published in Radiology, are Jeffry W. Prescott, MD, PhD, and his colleagues for their work investigating the brain’s structural connectome in the context of Alzheimer’s disease.

Looking for the key to happiness using MRI

For some, happiness comes from time with family. Others look for happiness in their bank accounts or among material possessions. Researchers from Kyoto University, however, have taken a different tactic in the search for happiness, leveraging structural MRI to address the issue from a neurological perspective.

Neuroimaging study shows concussions are harder on older brains

Age matters when it comes to recovering from mild traumatic brain injury. Perhaps unsurprisingly, it’s the younger patients who have more malleable neural plasticity, and so recover more fully and more quickly, than their older fellow sufferers.
