A study by an international research group identified 15 novel biomarkers that are linked to late-onset dementias. These biomarkers are proteins, which predict cognitive decline and subsequent increased risk of dementia already 20 years before the disease onset. The proteins are related to immune system dysfunction, blood-brain-barrier dysfunction, vascular pathologies, and central insulin…
A novel therapy engineered by Northwestern Medicine investigators improved progression-free and overall survival for patients with newly diagnosed malignant gliomas, according to results from a recent phase I clinical trial.
An EPFL scientist has found that brain fingerprints – or maps of the neural connections within our brain – can be used to detect a decline in cognitive ability. That’s because the fingerprints are harder to detect in people who already have mild cognitive impairment.
An international team of scientists led by EPFL has developed a system that combines information from the brain’s connectome – the “wiring” between neurons – and machine learning to assess and predict the outcome of stroke victims. When blood flow to the brain is somehow reduced or restricted, a person can suffer what we know as a stroke (from “ischemic stroke” in medical jargon).…
Dr. Hayder Amin and Dr. Caghan Kizil from the DZNE’s Dresden site aim to speed up developing drugs against brain diseases through cutting-edge technology. To this end, they are generating an innovative technology platform, termed “i3D-Markers”, based on high-density microelectrode arrays and 3-dimensional networks of human neurons. Compounds to be tested will be dripped onto this setup, and…
After a stroke, doctors can try to remove clots in blood vessels to keep blood flowing freely to the brain. But even though most of these procedures are successful, less than half of people have a successful recovery from the stroke. A new study published in the medical journal Neurology sheds light on why that may be. The study found that trying more than once during a procedure to retrieve a…
Researchers report that they have developed a method to combine three brain-imaging techniques to more precisely capture the timing and location of brain responses to a stimulus. Their study is the first to combine the three widely used technologies for simultaneous imaging of brain activity. The work is reported in the journal Human Brain Mapping. The new "trimodal" approach combines…
The effects of Covid-19 on the brain can be accurately measured with positron emission tomography (PET), according to research presented at the Society of Nuclear Medicine and Molecular Imaging (SNMMI) 2021 Annual Meeting. In the study, newly diagnosed Covid-19 patients, who required inpatient treatment and underwent PET brain scans, were found to have deficits in neuronal function and…
A new imaging technique has the potential to detect neurological disorders at their earliest stages, enabling physicians to diagnose and treat patients more quickly.
Research teams from TU Darmstadt, British and US universities are focusing on one possible main process that leads to the death of brain cells in their investigation of the causes and mechanisms of Alzheimer's disease.
Neurological disorders such as Parkinson’s disease and epilepsy have had some treatment success with deep brain stimulation, but those require surgical device implantation. A multidisciplinary team at Washington University in St. Louis has developed a new brain stimulation technique using focused ultrasound that is able to turn specific types of neurons in the brain on and off and precisely…
Brown University researchers have developed a technique that could allow deep brain stimulation devices to sense activity in the brain and adjust stimulation accordingly.
Researchers from ETH Zurich and University of Zurich have developed a new microscopy technique that lights up the brain with high resolution imagery. This allows neuroscientists to study brain functions and ailments more closely and non-invasively.
Two clusters of brain cells compete to promote either the persistence or disappearance of traumatic memories, according to a new study conducted in mice. The findings could provide important insights into human conditions such as post-traumatic stress disorder (PTSD), anxiety disorders, and associated problems such as alcohol use disorder (AUD) that can arise from the persistence of traumatic…
A new idea for treating Alzheimer’s disease could eradicate the toxic proteins most closely linked to cognitive decline in the places where they do the most damage, a study from researchers at Columbia University Vagelos College of Physicians and Surgeons suggests. The study was published online in Science Translational Medicine.
Researchers from Case Western Reserve University have identified a potential new approach to better controlling epilepsy. Lin Mei, professor and chair of the Department of Neurosciences at Case Western Reserve School of Medicine, who led the new study in mouse models, said the team found a new chemical reaction that could help control epileptic seizures.
Thin-film electrodes developed at Lawrence Livermore National Laboratory (LLNL) have been used in human patients at the University of California, San Francisco, generating never-before-seen recordings of brain activity in the hippocampus, a region responsible for memory and other cognitive functions. In a study published in the journal Nature Communications, surgeons at UCSF placed the flexible…
Scientists at the University College London (UCL) have made a ‘surprising’ discovery that glioblastoma, an aggressive brain cancer, mimics normal brain repair in white matter, which leads to the tumour becoming less malignant. In the study on mice, funded by Cancer Research UK and published in Nature Communications, researchers used these novel findings to identify drugs which could be used,…
Alzheimer's disease is characterized by the abnormal accumulation and spread of the tau protein in the brain. An international study can now show how tau spreads according to four distinct patterns that lead to different symptoms with different prognoses of the affected individuals. The study was published in Nature Medicine.
A new photonics device currently in development aims to reduce unnecessary disabilities by improving the instant, real-time monitoring of newborn babies with harmless light particles.
An artificial intelligence (AI)-driven system that automatically combs through brain MRIs for abnormalities could speed care to those who need it most, according to a new study. “There are an increasing number of MRIs that are performed, not only in the hospital but also for outpatients, so there is a real need to improve radiology workflow,” said study co-lead author Romane Gauriau, PhD,…
One of the characteristic hallmarks of Alzheimer’s disease (AD) is the buildup of amyloid-beta plaques in the brain. Most therapies designed to treat AD target these plaques, but they’ve largely failed in clinical trials. New research by scientists at the Salk Institute upends conventional views of the origin of one prevalent type of plaque, indicating a reason why treatments have been…
Researchers at the University of Oxford report that the risk of the rare blood clotting known as cerebral venous thrombosis (CVT) following Covid-19 infection is around 100 times greater than normal, several times higher than it is post-vaccination or following influenza. The study authors, led by Professor Paul Harrison and Dr Maxime Taquet from Oxford University’s Department of Psychiatry and…
At a cost of $38 billion a year, an estimated 5.3 million people are living with a permanent disability related to traumatic brain injury (TBI) in the United States today, according to the Centers for Disease Control and Prevention. The physical, mental and financial toll of a TBI can be enormous, but new research from the University of Georgia provides promise. In a new study, researchers at…
Tumor vaccines can help the body fight cancer. Mutations in the tumor genome often lead to protein changes that are typical of cancer. A vaccine can alert the patients' immune system to these mutated proteins. For the first time, physicians and cancer researchers from Heidelberg and Mannheim have now carried out a clinical trial to test a mutation-specific vaccine against malignant brain tumors.…
