Blood test detects risk of neurotoxicity from CAR T-cell therapy

Chimeric antigen receptor (CAR) T-cell therapy is an immunotherapy treatment that re-engineers a patient’s own T-cells to help them attack malignant tumour cells. It has been very effective in the treatment of blood cancers, including certain types of leukaemia and lymphoma. However, two serious side effects are common as a result of the treatment: cytokine release syndrome (CRS) and immune…

High-definition MRI reveals previously hidden territory of the human brain

Neuroscientists at Technische Universität Dresden discovered a novel, non-invasive imaging-based method to investigate the visual sensory thalamus, an important structure of the human brain and point of origin of visual difficulties in diseases such as dyslexia and glaucoma. The new method could provide an in-depth understanding of visual sensory processing in both health and disease in the near…

Low-field MRI: Less is more

Currently, two opposing trends can be observed in MRI: on the one hand 1.5T scanners are increasingly replaced by 3T scanners for standard clinical MRI applications. On the other hand scanners with lower and even significantly lower field strength have commercially available in the past two years. A session at this year’s European Congress of Radiology (ECR 2021) took a closer look at low-field…

‘Tau’ protein far more predictive for Alzheimer's damage than amyloid

Brain imaging of pathological tau-protein “tangles” reliably predicts the location of future brain atrophy in Alzheimer’s patients a year or more in advance, according to a new study by scientists at the UC San Francisco Memory and Aging Center. In contrast, the location of amyloid “plaques,” which have been the focus of Alzheimer’s research and drug development for decades, was found…

Drinking tea improves brain health

A recent study led by Assistant Professor Feng Lei from the National University of Singapore (NUS) Yong Loo Lin School of Medicine’s Department of Psychological Medicine revealed that regular tea drinkers have better organised brain regions – and this is associated with healthy cognitive function – compared to non-tea drinkers. The research team made this discovery after examining…

Is LATE the new Alzheimer’s?

A recently recognized brain disorder that mimics clinical features of Alzheimer’s disease has for the first time been defined with recommended diagnostic criteria and other guidelines for advancing and catalyzing future research. Scientists from several National Institutes of Health-funded institutions, in collaboration with international peers, described the newly-named pathway to dementia,…

Will your tattoo put you at risk during an MRI scan?

Tattoos are increasingly popular. Every eighth person in Germany has already felt the sting of getting a tattoo. A recent representative survey of the Federal Institute for Risk Assessment (BfR) revealed that nearly 90% of tattooed individuals considered them harmless to one’s health. Yet, if tattooed people are to be examined with magnetic resonance imaging (MRI), the question often arises of…

Will MRI be able to predict dementia?

One day, MRI brain scans may help predict whether older people will develop dementia, new research suggests. In a small study, MRI brain scans predicted with 89 percent accuracy who would go on to develop dementia within three years, according to research at Washington University School of Medicine in St. Louis and the University of California San Francisco. The findings, presented at the…

Blockchain: “Hype will fade but the technology will remain”

A new dimension in data handling is not only emerging, but is already a reality in our lives. However, political discourse about this often lags behind real events. We spoke with two experts who have an overview of clouds, decentralised data flows and the evaluation of personal data with IT help in various areas. Engineer Professor Alexandra Dmitrienko is a Secure Software Systems expert at the…

Just 4,000 steps a day to better brain health

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…

How the brain improves motor control

Adaptation in reaching - gradual improvement of motor control in response to a perturbation - is a central issue in motor neuroscience.However, even the cortical origin of errors that drive adaptation has remained elusive. In a new paper Inoue, Uchimura and Kitazawa have shown that error signals encoded by motor cortical neurons drive adaptation in reaching.

How the brain is organized

The age of exploration has long passed, but there is at least one area still largely uncharted: the human brain. Now, a detailed new map by researchers at Washington University School of Medicine in St. Louis lays out the landscape of the cerebral cortex – the outermost layer of the brain and the dominant structure involved in sensory perception and attention, as well as distinctly human…

The lost highway in the brain

A study three years ago sparked a medical mystery when it revealed a part of the brain not found in any present-day anatomy textbooks. Recently, Indiana University computational neuroscientist Franco Pestilli and an international research team published an article in the journal Cerebral Cortex that suggests this missing part of the brain may play an important role in how we understand the world…

Cardiorespiratory fitness contributes to successful brain aging

Cardiorespiratory fitness may positively impact the structure of white matter in the brains of older adults. These results suggest that exercise could be prescribed to lessen age-related declines in brain structure. The researchers together with Scott Hayes compared younger adults (age 18-31) to older adults (age 55-82).

Determining the site of deep brain implants

Uncontrollable convulsions, tremor or spasms can considerably impair the lives of neurodegenerative disease patients. Deep brain stimulation (DBS) – for which tiny electrodes are implanted in the brain to stimulate the target areas continuously with electrical impulses – can significantly reduce the movement disorder.

Molecular Imaging for Alzheimer’s Disease May Be Available in Hospitals Within One Year

Researchers the world over are advancing positron emission tomography (PET) as an effective method of early detection for Alzheimer’s disease, a currently incurable and deadly neurological disorder. Three studies presented at SNM’s 58th Annual Meeting are providing new insights into the development of Alzheimer’s disease while opening the door to future clinical screening and treatments.

New biomarkers allow for better diagnosis in multiple sclerosis

Biomarkers – mainly defined as surrogates serving as indicators for specific biological states – play an ever-increasing role in neuroscience and especially in the management of multiple sclerosis, scientists reported today at the 21st Meeting of the European Neurological Society (ENS) in Lisbon. In analyzing gene expression patterns, immunological changes and imaging abnormalities,…

Neuroimaging Technique Identifies Patients at Risk for Alzheimer’s Disease in Healthy Brains

How the brain changes with age is not well-characterized and even less is known about the factors influencing the rate of brain aging. Brain imaging can offer a window into risk assessment into for diseases such as Alzheimer’s disease. A recent study demonstrated that genetic risk is expressed in the brains of even those who are healthy, but carry some risk for AD.

Transforming medical diagnosis with new scanning technology

A new technology which dramatically improves the sensitivity of Magnetic Resonance techniques including those used in hospital scanners and chemistry laboratories has been developed by British scientists. The technique could replace current clinical imaging technologies that depend on the use of radioactive substances or heavy metals, which themselves create health concerns.
