Study links key protein to Charcot-Marie-Tooth and other nerve diseases

A new study provides critical insight into a little-known, yet relatively common, inherited neurological condition called Charcot-Marie-Tooth disease (CMT). The findings point to a pathway to possible treatments for this disease and better understanding of other neurodegenerative disorders, including Alzheimer's disease, that affect millions. The study focused on two related proteins, MFN2 and…

Study sheds new light on microglia

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…

Targeted deep brain stimulation reduces OCD symptoms

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…

When the compass fails

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.

AI and MRIs at birth can predict cognitive development

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…

Brain stimulation improves depression symptoms

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.

Some children can 'recover' from autism

Research in the past several years has shown that children can outgrow a diagnosis of autism spectrum disorder (ASD), once considered a lifelong condition. In a new study, researchers at Albert Einstein College of Medicine and Montefiore Health System have found that the vast majority of such children still have difficulties that require therapeutic and educational support.

Less-invasive procedure helps surgeons pinpoint epilepsy surgical candidates

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).

Researchers block protein to stop brain tumors' self-repair

Researchers at the San Diego branch of the Ludwig Institute for Cancer Research at University of California San Diego, with colleagues around the country, report that inhibiting activity of a specific protein in glioblastomas (GBM) boosts their sensitivity to radiation, thus improving treatment prospects for one of the most common and aggressive forms of brain cancer. The findings are published…

7-Tesla MR enters clinical routine

Ultra-high-field magnetic resonance tomography with field strength of 7 Tesla is slowly but surely entering clinical routine. ‘Thanks to very high spatial and spectral resolution, ultra-high-field MR permits detailed views of the human anatomy and can show precisely the metabolic processes such as those in the brain,’ said Professor Siegfried Trattnig, from Vienna’s Medical University.

When the brain turns white

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.

Progress in the treatment of glioblastoma

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.

How our brain works against 'night owls'

‘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.

Will education save you from dementia? Don't count on it

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…

Laughter may be best medicine for brain surgery

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…

Sleep deprivation accelerates Alzheimer’s brain damage

Poor sleep has long been linked with Alzheimer’s disease, but researchers have understood little about how sleep disruptions drive the disease. Now, studying mice and people, researchers at Washington University School of Medicine in St. Louis have found that sleep deprivation increases levels of the key Alzheimer’s protein tau. And, in follow-up studies in the mice, the research team has…

Alzheimer's: key to early prediction in the blood

Alzheimer's disease is often marked by a creeping progression: Years before symptoms of Alzheimer’s disease manifest, the brain starts changing and neurons are slowly degraded. Scientists at the German Center for Neurodegenerative Diseases (DZNE), the Hertie Institute for Clinical Brain Research (HIH) and the University Hospital Tübingen now show that a protein found in the blood can be used…

Dementia – MRI is the first step in diagnosis

Brain imaging in patients with cognitive complaints need to be viewed differently when using MRI to diagnose and treat patients with dementia, says Dr. Christopher Hess, who will discuss the role of MRI in the adjunctive diagnosis of dementia in his talk at the Garmisch Symposium. In addition, general radiologists need to recognize the important findings related to dementia when making a…

Can 'pacemaker for the brain' help to treat neurological disorders?

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…

Post-operative cognitive decline: mostly a myth, says study

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…

Parents’ brains ‘sync up’ with their infant’s when they play together

When infants are playing with objects, their early attempts to pay attention to things are accompanied by bursts of high-frequency activity in their brain. But what happens when parents play together with them?
