To mark the first European Parkinson’s Action Day on April 12th, the European Parkinson’s Disease Association (EPDA) announced the launch of a major new investigation into the care of people with Parkinson’s across 36 European countries. Parkinson’s disease is the second most common progressive neurodegenerative condition which affects people from all around the world.

NHS needs to invest in increasing specialists´nurses

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.

Handwriting revisited

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…

Parkinson's Disease: genetic risk factors identified

Two genes containing mutations known to cause rare familial forms of parkinsonism are also associated with the more common, sporadic form of the disease where there is no family history, researchers have found. An International study reveals common gene variants in people of European descent.

The first whole-body MRI-PET system

The technological integration of positron emission tomography (PET) and magnetic resonance imaging (MRI) has been the dream of molecular imaging experts and engineers for some time. Now, the German Science Council has agreed to provide 6.56 million funding to install a whole-body MRI-PET prototype in the centre of excellence for imaging procedures at the radiology clinic in Eberhard-Karls…

Safeguarding the future of MRI

Europe holds a leading position in the research and development of MRI, which has been used for over 25 years, imaging up to 500 million patients without evidence of harm to workers due to EMF exposure. It is also well known that MRI is free from health risks associated with ionising radiation such as X-rays, in many situations the alternative to MRI

Tasty and healthy food against chronic diseases

Now it seems to be proven: The reason why people in Mediterranean countries live longer and healthier can be connected with their nutrition. Researchers in Italy found that sticking rigidly to a full Mediterranean diet can help reduce deaths from major chronic diseases like heart disease, cancer, Parkinson's and Alzheimer's disease.

Eat Mediterranean to stay healthy

Mediterranean diet protects against chronic diseases like heart disease, cancer, Parkinson's and Alzheimer's disease. Italian scientists bolstering one more time the idea that low intake of meat, dairy products and alcohol, but high intake of vegetables, fruits, nuts, olive oil, grains and fish servers as a model of healthy eating, according to a study in the British Medical Journal.

Neurologists — an endangered species?

Irish and German neurology associations warn of an imminent shortage of neurologists. In Ireland, according to experts the situation is “lacking at best” and “catastrophic at worst”. German physicians as well detect increasing deficiencies in neurological care coverage primarily due to an aging population and concomitant morbidity.

Improved and faster analysis of MR images

Thanks to a new software, MR images from a five-minute scan may generate the images for a complete and comprehensive examination and therefore eliminating the need to perform multiple scans. The advanced software developed by Synthetic MR AB will be offered as a clinical application in Sectra´s PACS system.

First human ultrahigh-field MRI installed in the Netherlands

The Virtual Institute for Seven Tesla Applications (VISTA) is a partnership of several Dutch universities. To evaluate the benefit of ultrahigh-field MRI the first human 7.0T whole-body research scanner, supplied by Philips Medical Systems, was installed at the Leiden University Medical Center (LUMC). Roland Plasterk, the Durch minister of education, culture and science, attended at the opening…

World's first human brain images scanned with a PET/MRI hybrid system

The next-generation of hybrid imaging technology was presented at this years SNM meeting in Washington, D.C: The first human brain images from a prototype PET/MRI system, which is developed by a collaborative team of German and US researchers from the Universities of Tübingen and Tennessee, as well as Siemens Medical Solutions.

Treating Alzheimer with a skin patch

“Exelon Patch”, developed by Novartis is the first skin patch to treat patients with mild to moderate Alzheimer disease. The new therapy that has already been approved by the FDA, is said to be more compliant for it causes less incidents of nausea and vomiting.

Molecular imaging

GE was the first to undertake molecular imaging development on a large scale. 'You have to be a very special company to work in this discipline,' Reinaldo Garcia, President and Chief Executive Officer of GE Healthcare International, pointed out, when we asked for an update on his company's progress in this field

Cryoablation – a safer therapy for children with arrhythmias

Freezing abnormal electrical pathways in the hearts of young patients may be a safer alternative to zapping them with powerful radiofrequency probes to treat tachycardias and other arrhythmias, according to Dr Fabrizio Drago, of the Bambino Gesù Hospital, Rome. ‘If you have a child with a supraventricular tachycardia due to a re-entry circuit, or a target very close to the atrioventricular…

PET scanning the heart cuts costs

USA - Using positron emission tomography (PET) scanning rather than other types of imaging as the first tool to diagnose heart-vessel blockages is more accurate, less invasive and saves money, according to researchers reporting at the American College of Cardiology's Annual Scientific Session in March.

The MRI-MARCB project

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...).

Neurology: Let's get nervous

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.
