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.

Changes in brain connectivity correlates with Parkinson’s symptoms

By using functional magnetic resonance imaging (fMRI) to study the organization of the brain’s connectome, researchers have shown certain alterations in the brain’s connectivity correlate with symptoms of Parkinson’s Disease (PD), such as motor disturbances.

MRI illuminates changes in brain microstructure after concussion

Considering the growing concern about concussions in youth sports, recent research examined how advanced MRI can be used to better understand how brain injuries can result in neurobiological changes that impact clinical recovery.

Pennsylvania patient area's first to receive ultrasound treatment for essential tremor

John Lukens, 61, who suffered from bilateral essential tremor (ET) for about a decade, recently became the first patient in Pennsylvania to receive MR-guided Focused Ultrasound Treatment (MRgFUS) for ET.

Bipolar individuals have abnormalities in frontal, temporal regions of brain

An international consortium spanning 76 centers published a large MRI study that found abnormalities in brain regions controlling inhibition and emotion in individuals with bipolar disorder.

Brain MRI shows gender-specific approaches should be considered in treating alcoholism

Researchers at Massachusetts General Hospital and Boston University School of Medicine used brain MRIs in a new study to find the effects of alcoholism on the brain’s reward system may be different in women and men.

Researchers use electrical neuroimaging to find cause of chronic fatigue syndrome

A team of researchers from the Center for Community Research at DePaul University are using electrical neuroimaging to better understand why the brain is less efficient in people with chronic fatigue syndrome (CFS), also known as myalgic encephalomyelitis (ME).

fMRI: Lack of sleep may dim positive thinking in those with anxiety, depression

University of Illinois at Chicago (UIC) College of Medicine researchers have found that the dorsal anterior cingulate cortex (DACC) may have to work harder to modify negative emotional responses in people with poor sleep who have depression or anxiety.

Retired NHL hockey players examined for cognitive and psychological function

Researchers at Baycrest Health Sciences’ Rotman Research Institute found that retired professional ice hockey players involved in their neuropsychological study were free from significant brain impairment on objective testing. However, these players reported a high level of emotional, behavioural and cognitive challenges.

fMRI shows difference between patience, imagination in the brain

A group of neuroscientists used functional MRI (fMRI) to discover links between being patient and imagination in the brain. According to findings, imagining an outcome before acting upon an impulse may help increase patience without relying on increased willpower.

PET scans show dopamine imbalance during migraine

When patients who suffer from migraine underwent PET scans, researchers found a reduction and fluctuation of dopamine in their brains during the headache attack.
