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-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…
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…
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 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…
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…
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…
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, 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…
Together with three other neuroscientists Professor Christian Haass, speaker of the German Center for Neurodegenerative Diseases (DZNE) Munich site and Professor at the Ludwig-Maximilians-University of Munich, receives the world’s most valuable prize for brain research. The 2018 Brain Prize, awarded by the Lundbeck Foundation in Denmark, is worth one million Euros. Awarded annually, it…
‘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…
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.
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…
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…
Watching too much television at age 2 can translate into poorer eating habits in adolescence and poorer performance in school, researchers at Université de Montréal’s School of Psychoeducation have found. In a new longitudinal study published in Preventive Medicine, graduate student Isabelle Simonato and her supervisor, Professor Linda Pagani, looked at a birth cohort of nearly 2,000 Quebec…
While a couple of glasses of wine can help clear the mind after a busy day, new research shows that it may actually help clean the mind as well. The new study, which appears in the journal Scientific Reports, shows that low levels of alcohol consumption tamp down inflammation and helps the brain clear away toxins, including those associated with Alzheimer’s disease. “Prolonged intake of…
What if one of the prime suspects behind Alzheimer’s disease was a case of mistaken identity? Amyloid plaques, sticky buildup that accumulates in and around neurons in the brain, have long been believed to be an indicator of neurodegenerative disease. Most clinical drug trials for Alzheimer’s disease treatment have failed, presumably because they target these plaques. But according to Raymond…
The emerging field of psychoradiology is taking a major step ahead. A new study highlights MRI’s role in identifying people with attention deficit and hyperactivity disorder (ADHD) and classifies subtypes of the condition, a leading Chinese researcher explained at the ESMRMB annual meeting.
Engineers at the University of Connecticut (UConn) have created a biodegradable pressure sensor that could help doctors monitor chronic lung disease, swelling of the brain, and other medical conditions before dissolving harmlessly in a patient’s body. The UConn research is featured in the current online issue of the Proceedings of the National Academy of Sciences. The small, flexible sensor is…
UCLA researchers have developed the first map of gene regulation in human neurogenesis, the process by which neural stem cells turn into brain cells and the cerebral cortex expands in size. The scientists identified factors that govern the growth of our brains and, in some cases, set the stage for several brain disorders that appear later in life. The human brain differs from that of mice and…
It is wartime. You and your fellow refugees are hiding from enemy soldiers, when a baby begins to cry. You cover her mouth to block the sound. If you remove your hand, her crying will draw the attention of the soldiers, who will kill everyone. If you smother the child, you’ll save yourself and the others. If you were in that situation, which was dramatized in the final episode of the ’70s and…
Exercising twice a week may improve thinking ability and memory in people with mild cognitive impairment (MCI), according to a guideline released by the American Academy of Neurology. The recommendation is an update to the AAN’s previous guideline on mild cognitive impairment and is published in the online issue of Neurology, the medical journal of the American Academy of Neurology. The…
While cognitive abilities naturally decline with age, eating one serving of leafy green vegetables a day may aid in preserving memory and thinking skills as a person grows older, according to a study by researchers at Rush University Medical Center in Chicago. The study results were published in Neurology, the medical journal of the American Academy of Neurology. “Adding a daily serving of…
Walking more than 4,000 steps a day can improve attention and mental skills in adults ages 60 and older, according to UCLA research published December 12 in a preprint edition of the Journal of Alzheimer’s Disease. Various studies have found that physical activity is important in preventing cognitive decline and dementia in older adults. Cognitive decline occurs when people start having…
Although targeted therapies have produced dramatic advances in our ability to control some types of advanced lung cancer, growth of the disease in the brain remains a major problem. Radiation is often used to treat deposits in the brain, but the best technique to deliver radiation can be controversial. Whole-brain radiation therapy, as its name suggest, treats the entire brain but can be…
