Inside the body, disease and injury can leave behind quite the mess — a scattering of cellular debris, like bits of broken glass, rubber and steel left behind in a car accident. Inside the central nervous system (CNS), a region that includes the brain and spinal cord, it is the job of certain cells, called microglia, to clean up that cellular debris. Microglia have counterparts called…
Some studies have suggested that minerals such as zinc and iron may play a role in how multiple sclerosis (MS) progresses, once people have been diagnosed with it. But little was known about whether zinc, iron and other minerals play a role in the development of the disease. A new study shows no link between dietary intake of several minerals and whether people later develop MS. The study is…
The debilitating behaviours and all-consuming thoughts which affect people with severe obsessive compulsive disorder (OCD), could be significantly improved with targeted deep brain stimulation, according to the findings of a new study. OCD is characterised by unwanted intrusive thoughts (obsessions) and repetitive stereotyped behaviours (compulsions- sometimes called rituals) and often means…
It’s undeniable: the bulk of our population is growing older. Yet, this demographic change has not altered laboratory medicine: the reference values for many analyses are still based on data of a younger cohort. Inevitably this could lead to serious errors in the interpretation of older patients’ test results.
Where are we coming from? Where are we going? Where are we right now? Our sense of spatial orientation gives us answers to these questions. We spoke with Professor Thomas Wolbers about the problems of diagnosing orientation disturbances and how the measurement of our sense of space could help in the fight against neuro-degenerative illnesses such as Alzheimer’s.
Neurological complications due to infections with (novel) enteroviruses are rarely the focus of medical research. Thus, an article published in the German medical journal Der Nervenarzt (published at the Medizinische Hochschule Hanover (MHH) – has created quite a stir. We spoke with one of the authors, Professor Martin Stangel, about current clinical practice in terms of enterovirus.…
A study has identified chemicals in the skin responsible for a unique scent in people with Parkinson’s disease. The chemicals can be detected in an oily substance secreted from the skin called sebum, the researchers found. The findings suggest Parkinson’s disease could one day be diagnosed from skin swabs, potentially leading to new tests. There are no tests for Parkinson’s disease at…
Researchers at the University of North Carolina School of Medicine used MRI brain scans and machine learning techniques at birth to predict cognitive development at age 2 years with 95 percent accuracy. “This prediction could help identify children at risk for poor cognitive development shortly after birth with high accuracy,” said senior author John H. Gilmore, MD, Thad and Alice Eure…
With a weak alternating electrical current sent through electrodes attached to the scalp, UNC School of Medicine researchers successfully targeted a naturally occurring electrical pattern in a specific part of the brain and markedly improved depression symptoms in about 70 percent of participants in a clinical study.
A minimally invasive procedure to determine whether patients with drug-resistant epilepsy are candidates for brain surgery is safer, more efficient, and leads to better outcomes than the traditional method, according to new research by The University of Texas Health Science Center at Houston (UTHealth).
White matter on the brain is a difficult subject. Even the terminology is varied, making differential diagnosis complex. An understanding of prevalence and of the tools available to facilitate the diagnosis of individual diseases is important, Dr Gunther Fesl, radiologist at Praxis Radiologie Augsburg, explains.
Cancer researchers at the University of Bonn have reported significant progress in the treatment of glioblastoma. About one third of all patients suffer from a particular variant of this most common and aggressive brain tumor. Survival of these patients treated with the new combination therapy increased on average by nearly half compared to patients who received the standard therapy.
‘Night owls’ – those who go to bed and get up later – have fundamental differences in their brain function compared to ‘morning larks’ , which mean they could be disadvantaged by the constraints of a normal working day.
The pill could be blurring your social judgement ‒ but perhaps not enough so you'd notice. By challenging women to identify complex emotional expressions like pride or contempt, rather than basic ones like happiness or fear, scientists have revealed subtle changes in emotion recognition associated with oral contraceptive pill (OCP) use. Published in Frontiers in Neuroscience, their study found…
Until now, neurologists were largely convinced that having a higher level of education would build some kind of protective barrier against neurodegenerative diseases like Alzheimer's. But a new study finds that education does not play a role in when the disease starts or how fast it progresses. The study was published in the online issue of Neurology, the medical journal of the American Academy…
Neuroscientists at Emory University School of Medicine have discovered a focal pathway in the brain that when electrically stimulated causes immediate laughter, followed by a sense of calm and happiness, even during awake brain surgery. The effects of stimulation were observed in an epilepsy patient undergoing diagnostic monitoring for seizure diagnosis. These effects were then harnessed to help…
A new study shows that there is a very limited regeneration of cells in the brain of patients diagnosed with multiple sclerosis (MS). These findings underline the importance of treating MS at an early stage of the disease progression, when the affected cells can repair the damage as they are not replaced by new ones. The results are published in the journal Nature by researchers from Karolinska…
Activating a neural pathway from the Ventral Tegmental Area (VTA) to the Dorsal Raphe Nucleus (DRN) could significantly reduce morphine addiction while not affecting its analgesic effect, suggests new research led by Prof. Li Xiaoming from Zhejiang University’s School of Medicine. The study, published in the January issue of Neuron, found two parallel inhibitory neural pathways from VTA to DRN:…
Half of those who develop a severe mental disorder such as depression prior to the age 20, will also develop an anxiety disorder within the next 15 years. This is just one of the many results on the relationship between various mental disorders mapped out.
Longer hours, more demanding working practices, complex cases and increased administration are taking their toll on physicians as growing numbers, across a range of specialties, report signs of burnout. All this despite technological advances such as artificial intelligence and machine learning to aid diagnosis, read and interpret images, improve workflow and enhance decision-making.
In a new study, researchers at the Biodesign Institute explore a safe and simple treatment for one of the most devastating and perplexing afflictions: Alzheimer’s disease (AD). Lead authors Ramon Velazquez and Salvatore Oddo, along with their colleagues in the Arizona State University (ASU)-Banner Neurodegenerative Disease Research Center (NDRC), investigate the effects of choline, an important…
Using a common type of brain scan, researchers programmed a machine learning algorithm to diagnose early-stage Alzheimer's disease about six years before a clinical diagnosis is made – potentially giving doctors a chance to intervene with treatment.
A new neurostimulator developed by engineers at the University of California, Berkeley, can listen to and stimulate electric current in the brain at the same time, potentially delivering fine-tuned treatments to patients with diseases like epilepsy and Parkinson's. The device, named the WAND, works like a "pacemaker for the brain," monitoring the brain's electrical activity and…
As mammals age, their sense of smell deteriorates. In a study published in the journal ‘Cell Reports’, an interdisciplinary research team at Helmholtz Zentrum München and the University Medical Centre Mainz investigated why this is the case. For their study, the researchers tracked the development of stem cells in the brains of mice using what are known as confetti reporters. They then…
Patients who undergo heart surgery do not experience major memory changes—either better or worse—when compared with those who have a much less invasive, catheter-based procedure, according to a study published online in The Annals of Thoracic Surgery. “It was comforting to see that the differences in cognitive decline between the two heart procedures are small, even though one involves…
