Progress in miniaturising sensor technology has opened up new possibilities for monitoring vital signs outside the hospital environment. A subset of wearables are the so-called hearables – in-ear devices that are well suited for long-term monitoring as they are non-invasive, inconspicuous and easy to fasten. Hearables offer two major benefits: their proximity to the torso and vascular system of…

Children who suffer repeated febrile convulsions have an increased risk of developing epilepsy and psychiatric disorders such as schizophrenia and depression later in life. This is shown by a comprehensive register-based study from Aarhus University. The risk of febrile convulsions increases with the child’s fever, and approximately four per cent of Danish children suffer from febrile…
In some forms of epilepsy, the function of certain "brake cells" in the brain is presumed to be disrupted. This may be one of the reasons why the electrical malfunction is able to spread from the point of origin across large parts of the brain. A current study by the University of Bonn, in which researchers from Lisbon were also involved, points in this direction. The results are…
A person with drug resistant epilepsy who gets an early surgical intervention has a better chance of becoming seizure free. This is shown in a systematic review and meta-analysis in which Sahlgrenska Academy researchers, in collaboration with the Swedish Council for Assessment of Health Technology and Social Services (SBU), analysed results from a range of previous studies. They concluded that…
Epilepsy affects around 70 million people worldwide, making it the second most common neurological disorder after migraine. Epileptics bear a terrible burden because they experience recurrent seizures that strike without warning. Their symptoms range from brief suspension of awareness to violent convulsions and sometimes loss of consciousness. Epilepsy is also responsible for numerous deaths –…
The speed of the human brain is remarkable. Almost immediately upon being exposed to stimuli, neurons are activated, prompting subconscious reactions and, a fraction of a second later, thought. But the speed at which we can noninvasively follow brain function using an MRI is not as impressive. Functional MRI (fMRI), which measures changes in blood-oxygen levels, has revolutionized neuroscience by…

The coordination of neural activity across widespread brain networks is essential for human cognition. Researchers have long assumed that oscillations in the brain,…
Weak, easily broken bones are an epidemic in the United States. They’re often tied to osteoporosis, a disease that causes bones to degenerate over time. This makes them less flexible, more brittle, and easier to break. According to the International Osteoporosis Foundation, more than 44 million Americans aged 50 and older either have or face the threat of developing osteoporosis due to low bone…

‘With our new MRI method, we can finally visualise tiny leaks in the blood-brain barrier. They shed light on the vascular contribution to dementia and may indicate Alzheimer’s disease. However, the MRI scan is only a tool to diagnose cerebrovascular damage. We have not yet found a cure for Alzheimer’s,’ confirms Walter H Backes, medical physicist and professor at Maastricht University…

But there has been no way to predict which child with the abnormality might be…
During the transition from child to adult many teens with chronic diseases somehow slip through the healthcare cracks between paediatric and adult medicine. Compliance deteriorates, regular check-ups are missed – an international problem, as many studies indicate. A promising programme, launched in Berlin, helps teens to manage this difficult change. Report: Bettina Döbereiner
Pain is the point of departure of any medical interaction. When a body sends out pain signals to say that something is wrong, the person in pain will react – either by selfmedication or by consulting a physician.

Anti-seizure medication is not successful in all patients, while in others such medication can have side effects. In recent years significant technical advances have delivered better imaging results, which, combined with growing demand for a surgical solution from patients whose medications do not control seizures, or those not wanting to take medication constantly, has led to an increase in…
Today’s first European Epilepsy Day sees the launch of Epilepsy In Our Time, an exploration of the lives of five people living with epilepsy across Europe today, through their own video diaries. Lloyd, Marion, Monica, David and Julie invite you to take a look at their personal experiences of living with epilepsy and their hopes for the future.
Neurons communicate via chemical transmitters which they store in the bubble-like synaptic vesicles and release as required. To be able to react reliably to stimulation, neurons must have a certain number of "acutely releasable" vesicles. With the help of a new method, German neuroscientists have now discovered that neurons systematically recycle the protein components necessary for transmitter…
„Diseases of the nervous system and the brain occur more frequently than cancer. According to recent calculations of health care costs, they represent a burden of 386 billion euros a year on European economies,“ says Prof. Gérard Said, newly elected president of the European Neurological Society (ENS) at the annual meeting in Berlin, Germany. „This is often greatly underestimated.“
The Royal College of Nursing (RCN) has joined forces with almost 40 of the UK's leading health organisations to warn that cutting specialist nurse services for people with long term conditions would be a "false economy", as they began a campaign for guaranteed access to specialist nursing care for all patients with long term conditions.
