More than 80 billion neurons, trillions of synapses and almost 6 kilometres of neural pathways: The brain is an anatomical masterpiece; it is our control centre, memory store, coordinator of thoughts and movement – and still puzzles science. In medicine, the focus is on neurodegenerative diseases such as Alzheimer's and Parkinson's, but also on cerebrovascular disorders such as strokes and brain tumours, notably glioblastoma.
After an infection with the coronavirus Sars-CoV-2, the virus is able to persist at low levels in the brainstem, new research finds. This helps explain some of the enduring neurological symptoms.
A new method to monitor blood flow in the brain helps neurosurgeons detect the risk of a stroke during surgery – and potentially prevent it. This could also be useful for other types of operations.
Using electrodes implanted in the brain, researchers observed specific brain waves that could serve as a biomarker for obsessive-compulsive disorder (OCD) and are an important step towards more targeted treatments.
The earlier Alzheimer's disease is detected, the more effective treatments become. Now, a Finnish study shows that signs related to Alzheimer’s may already be found in the brain in middle age.
In an unconventional, but promising approach to treat neurological conditions like Parkinson, researchers use nanoscale magnetic pull to rebuild lost conncections between brain cells.
What do the brains of newborns and patients with Alzheimer's disease have in common? Researchers have discovered a surprising shared trait - which might provide new insights into the disease.
Using a keyhole surgery approach, surgeons have found a new way to access previously difficult-to-reach brain regions with faster recovery times. With the help of 3D modelling technology, the neurosurgeons succeeded in removing complex tumours from the cavernous sinus through the eye socket, avoiding complex brain surgery and enabling their patients to make a quicker recovery.
Researchers evaluated the clinical value of using ChatGPT to interpret seizure semiology in order to predict which brain areas to remove to achieve seizure freedom in epilepsy patients.
A new biomarker for multiple sclerosis: the inflammatory cell rim from microglial cells surrounding brain lesions was found to directly correlate with the severity and speed of disease progression.
Bringing diagnostics and therapy closer together - that is the basic concept behind theranostics. Through further development of its PET/MR scanners, Siemens Healthineers aims to advance this approach. Andreas Schneck, Head of the MRI Division at Siemens Healthineers, talks about the new system, which was also presented at the European Congress of Radiology (ECR) in Vienna, and its advantages in…
Using an advanced PET scanner, US radiologists explore how cancer, neurodegenerative diseases and other systemic conditions, can affect the brain by assessing the impact on the blood-brain barrier.
Researchers have succeeded in mapping how blood vessels in the brain react after a stroke. This new insight can lead to more effective treatment and fewer complications for patients.
A new AI tool can extract key information from brain MRI scans of multiple sclerosis (MS) patients. This could be used to improve disease and treatment response monitoring.
New research has revealed how Duchenne muscular dystrophy (DMD) also profoundly affects the brain, leading to cognitive and behavioural challenges that are very diverse and some could be reversible.
Using the COX-2 enzyme, a new PET imaging approach offers a never-before-seen view of inflammation in the brain, opening the door for clinical and research settings for various brain disorders.
Using ‘parallel transmit’ technique, researchers have found a new way to detect lesions in the brain of patients with treatment-resistant epilepsy in an MRI scan, without imaging signal dropouts.
Electrodes implanted directly onto the brain’s visual cortex could eventually restore a rudimentary form of vision to people suffering from blindness worldwide, new research suggests.
A novel sensor placed on a patient’s head registers nanometric expansions of the skull in each cardiac cycle in real time to measure intracranial pressure more accurately and non-invasively.
Researchers developed a new scanning method that combines light and ultrasound to non-invasively monitor cerebrovascular changes in the early stages of an ischemic stroke in real time.
