Behaviour prediction

The psychology of taking risks

An anxious person will avoid risks whenever possible. This in itself is not exactly a surprise. However, researchers have found a way to visualize this process in the brain - with interesting implications for behaviour prediction. A team of psychologists from the German Friedrich Schiller University Jena, together with partners from Würzburg, Germany and Victoria, Canada they conducted an…

Why being left-handed matters for mental health treatment

Being left-handed apparently means a lot more than gripping things differently than most, researchers find. This sheds a new light on mental health treatment, because current therapies for the most common mental health problems could be ineffective or even detrimental to about 50 percent of the population. For more than 40 years, hundreds of studies suggest that each hemisphere of the brain is…

Waves move across the human brain to support memory

Biomedical engineers at Columbia Engineering have discovered a new fundamental feature of brain oscillations: they actually move rhythmically across the brain, reflecting patterns of neuronal activity that propagate across the cortex. The coordination of neural activity across widespread brain networks is essential for human cognition. Researchers have long assumed that oscillations in the brain,…

The brain’s “rising stars”: New options against Alzheimer’s?

A study by scientists of the German Center for Neurodegenerative Diseases (DZNE) points to a novel potential approach against Alzheimer’s disease. In studies in mice, the researchers were able to show that blocking a particular receptor located on astrocytes normalized brain function and improved memory performance. Astrocytes are star-shaped, non-neuronal cells involved in the regulation of…

Music activates regions of the brain spared by Alzheimer’s disease

Ever get chills listening to a particularly moving piece of music? You can thank the salience network of the brain for that emotional joint. Surprisingly, this region also remains an island of remembrance that is spared from the ravages of Alzheimer’s disease. Researchers at the University of Utah Health are looking to this region of the brain to develop music-based treatments to help alleviate…

Groundbreaking technique

Noninvasive brain tumor biopsy on the horizon

Taking a biopsy of a brain tumor is a complicated and invasive surgical process, but a team of researchers at Washington University in St. Louis is developing a way that allows them to detect tumor biomarkers through a simple blood test. Hong Chen, a biomedical engineer, and Eric C. Leuthardt, MD, a neurosurgeon, led a team of engineers, physicians and researchers who have developed a…

Gadolinium @ ECR 2018 – diverse and “disunited”?

Gadolinium-containing/gadolinium-based contrast agents (GCCAs/GBCAs) and their usage was a major topic at ECR 2018. Fuelled by the current debate a number of presentations focused on possible impact, risks and necessities. Some were highly specific, others took a broader view. The only consensus, however, seems to be the need for more research and the focus on safety. Three ECR speakers, Joseph…

Immunological memory

Our brains 'remember' inflammation and diseases

Inflammatory reactions can change the brain’s immune cells in the long term – meaning that these cells have an ‘immunological memory’. This memory may influence the progression of neurological disorders that occur later in life, and is therefore a previously unknown factor that could influence the severity of these diseases. Scientists at the German Center for Neurodegenerative Diseases…

Long-term caffeine

There's a catch to your daily coffee intake, study finds

A study coordinated by the Institute of Neuroscience of the Universitat Autònoma de Barcelona (Inc-UAB) and in collaboration with the Karolinska Institutet (KI) in Sweden provides evidence that a long-term consumption of caffeine has negative effects for Alzheimer’s disease, worsening the neuropsychiatric symptoms appearing in the majority of those affected by the disorder. The research was…

Alzheimer’s, Parkinson’s and Huntington’s

The role of misfolded proteins in neurodegenerative diseases

Alzheimer’s, Parkinson’s and Huntington’s disease may have more in common than their effects on the functions of the brain and spinal cord. And finding that common thread could lead to a treatment that could work for all three. A recent study by David Smith, associate professor of biochemistry in the West Virginia University School of Medicine, suggests that at the heart of all three…

Triggering inflammatory reactions

Parkinson’s gene initiates disease outside of the brain

Until very recently, Parkinson’s had been thought a disease that starts in the brain, destroying motion centers and resulting in tremors and loss of movement. New research published this week, shows the most common Parkinson’s gene mutation may change how immune cells react to generic infections like colds, which in turn trigger the inflammatory reaction in the brain that causes…

Anti-rejection medicine

Drugs used after organ transplant could protect against Alzheimer’s

A UT Southwestern study in mice provides new clues about how a class of anti-rejection drugs used after organ transplants may also slow the progression of early-stage Alzheimer’s disease. Alzheimer’s, a progressive form of dementia, affects an estimated 5 million people in the U.S. – a number expected to nearly triple by 2050. Although Alzheimer’s usually strikes after age 65, changes in…

'Beeting' Alzheimer's with vital vegetable compound

A compound in beets that gives the vegetable its distinctive red color could eventually help slow the accumulation of misfolded proteins in the brain, a process that is associated with Alzheimer’s disease. Scientists say this discovery could lead to the development of drugs that could alleviate some of the long-term effects of the disease, the world’s leading cause of dementia. The…

Stephen Hawking leaves a lasting legacy

Stephen Hawking, a visionary physicist, as well as a pop culture icon, died March 14 2018 at the age of 76, leaving scientists, doctors, space enthusiasts and “Simpsons” fans alike to reflect on his contributions to modern cosmology and entertainment. Hande Ozdinler, an associate professor in the department of neurology in Northwestern’s Feinberg School of Medicine, reflects on Hawkings…

Gadolinium deposition: A real threat or a phantom debate?

The European Medicines Agency (EMA) decided to suspend authorisation for certain linear gadolinium agents. The review by the Committee for Medicinal Products for Human Use (CHMP) states: “There is currently no evidence that gadolinium deposition in the brain has caused any harm to patients; however EMA has recommended restrictions and suspensions for some intravenous linear agents in order to…

A new hope for Alzheimer's prediction

New information on dementia biomarkers is emerging, as increasing results from population studies become available. However, although the list of risk factors lengthens, the value of these predictors, and more generally the cause of disease, remain to be determined, according to Gabriel Krestin, professor and chairman of the Department of Radiology & Nuclear Medicine at Erasmus MC, University…

MRI vs. Alzheimer's

Seeking leaks in the blood-brain barrier

‘With our new MRI method, we can finally visualise tiny leaks in the blood-brain barrier. They shed light on the vascular contribution to dementia and may indicate Alzheimer’s disease. However, the MRI scan is only a tool to diagnose cerebrovascular damage. We have not yet found a cure for Alzheimer’s,’ confirms Walter H Backes, medical physicist and professor at Maastricht University…

Reason must prevail in debates on GCCAs use

Radiologists must ensure precise scientific data and radiology-based evidence are used to regulate the use of Gadolinium Containing Contrast Agents (GCCAs), a Spanish leading radiologist explained in closed-door leadership meeting earlier this year in Barcelona.
