Stroke patients will first undergo a CT scan as they enter the hospital. Before any further imaging scan is carried out, the medical team must decide whether they need to intervene intra or extra cranially. ‘Imaging enables you to see which pathology you are dealing with and helps you select patients for either recanalisation or revascularisation or, in some cases, occlusion by embolisation,’…
‘An autonomously working robot in the operating theatre will continue to be a vision of the future for a long time to come,’ according to Professor Uwe Spetzger, Clinical Director and Neurosurgery Specialist at Karlsruhe City Hospital. At the same time, he is calling for political support for the development and promotion of these innovative technologies and asking funding bodies to rethink…
The cause of Alzheimer’s disease remains unknown. Early diagnosis is currently not possible as clinical symptoms only occur once a large number of neurones in the brain have already been destroyed. There is no treatment available either.
The mechanism by which drug-resistant bacteria maintain a defensive barrier has been identified by researchers at England’s University of East Anglia (UEA) and their findings could result in a new wave of drugs that can bring down those defensive walls rather than attack the bacteria – thus they may not develop drug-resistance at all.
Studying a new type of pinhead-size, lab-grown brain made with technology first suggested by three high school students, Johns Hopkins researchers have confirmed a key way in which Zika virus causes microcephaly and other damage in fetal brains: by infecting specialized stem cells that build its outer layer, the cortex.
Accurate diagnosis of Parkinson's disease, and the related disease "dementia with Lewy bodies," can be difficult in the early stages of both conditions. While brain biopsies can be more accurate, the risk of complications has been considered too high.
When there is an accident or a house fire, we call the police or the fire services. A control room quickly coordinates emergency operations. The cells in our bodies also have helpers in a crisis; the heat-shock proteins. These are triggered in response to cellular stress, such as high temperature, UV radiation or cancer. Heat-shock proteins help other proteins maintain their functional structure…
An international public-private research consortium has identified and validated a cellular role of a primary Parkinson’s disease drug target, the LRRK2 kinase. This important finding illuminates a novel route for therapeutic development and intervention testing for Parkinson’s, the second most common neurodegenerative disease after Alzheimer’s.
École polytechnique fédérale de Lausanne (EPFL) scientists have developed a new method that turns cells into stem cells by "squeezing" them. The method paves the way for large-scale production of stem cells for medical purposes.
Proteins are like a body’s in-house Lego set. These large, complex molecules are made up of building blocks called amino acids. Most of the time, proteins fold correctly, but sometimes they can misfold. This misfolding causes the proteins to get sticky, and that can promote clumping, or aggregation, which is the hallmark of several neurodegenerative diseases such as ALS, Alzheimer’s and…
By implanting electrodes in the brain tissue one can stimulate or capture signals from different areas of the brain. These types of brain implants, or neuro-prostheses as they are sometimes called, are used to treat Parkinson's disease and other neurological diseases.
People with Parkinson’s disease (PD) tend to slow down and decrease the intensity of their movements even though many retain the ability to move more quickly and forcefully. Now, in proof-of-concept experiments with “joysticks” that measure force, a team of Johns Hopkins scientists report evidence that the slowdown likely arises from the brain’s “cost/benefit analysis,” which gets…
Researchers at the University of Maryland and the University of Virginia have performed the first focused ultrasound treatments in the United States for dyskinesia associated with Parkinson’s disease.

“I am very concerned about the impact that Angelina Jolie has on the media,” Walter Rocca, professor of epidemiology and neurology at the Mayo Clinic in Rochester, Minnesota, stated. He wasn’t hinting to Jolie’s acting choices or waifish silhouette, but to the confusion surrounding her decision to remove her ovaries to prevent ovarian cancer. By Mélisande Rouger

Researchers at Karolinska Institutet have shown that they may be able to monitor the aging process in the brain, by using MRI technique to measure the brain lactic acid levels. Their findings suggest that the lactate levels increase in advance of other aging symptoms, and therefore could be used as an indicator of aging and age-related diseases of the CNS.

A specialised brain area involved in the production of written language was first empirically described by 19th century scientist S. Exner. At that time, the only way to investigate was by post mortem study of patients who had experienced writing problems during their lives. Now, in France, a team of researchers led by Jean François Démonet, has applied state-of-the art technology to study…

Despite advances in magnetic resonance imaging (MRI) that have revolutionised diagnostic possibilities, e.g. for functional imaging (fMRI), motion artifacts are still extremely detrimental in multi-slice 3D sequences, often used in fMRI or with uncooperative patients (children, elderly, accidents, stroke...).
Neural networks are emblematic of complex systems, so it's no surprise that the field of neurology is eclectic and intricate, too. Main challenges for neurologists are therapies of and research on stroke, seizures, movement disorders such as Parkinson's disease, autoimmune disorders such as multiple sclerosis and dementias such as Alzheimer's disease.
