Photo: Image of brain [10/06/2015] Brain lesions in children can be especially challenging to diagnose, according to a report by a multidisciplinary team of Loyola University Medical Center physicians. Lesions include tumors, abnormal blood vessel formations and abscesses and inflammation due to infections.Brain lesions in children challenging to diagnose - Read more

Strokes steal 8 years' worth of brain function

Photo: Images of brain [08/06/2015] Having a stroke ages a person's brain function by almost eight years, new research finds - robbing them of memory and thinking speed as measured on cognitive tests. In both black and white patients, having had a stroke meant that their score on a 27-item test of memory and thinking speed had dropped as much as it would have if they had aged 7.9 years overnight.Strokes steal 8 years' worth of brain function - Read more

Their research shows that even during quiet moments, our brains are preparing us to be socially connected to other people.Our brains prepare us to be social while resting - Read more

"Neuromonitoring during lesser pelvis surgery is still uncharted territory"

Graphic: Drawing of the human sacrum [08/05/2015] The bowel is surrounded by a dense plexus of nervous tissue that presents problems for surgeons. On the one hand, it is difficult to distinguish from the surrounding tissue; while on the other hand, sometimes portions of it need to be removed when parts of the colon are removed. Yet injuring these nerves can result in permanent damage."Neuromonitoring during lesser pelvis surgery is still uncharted territory" - Read more

A new study by Ludwig-Maximilians-Universität (LMU) in Munich researchers now attributes the syndrome to post-traumatic stress induced by diagnosis of the disease.Chemobrain: Cancer diagnosis affects cognitive function - Read more

Multiple sclerosis: A riddle of the blood-brain barrier solved

Photo: Loop with a script Multiple Sclerosis [10/04/2015] The creation and progression of multiple sclerosis present scientists with many riddles. Now researchers from the universities of Würzburg and Amsterdam have succeeded in resolving an apparent contradiction in the findings to date. Their work will contribute to a better understanding of the impact of treatments at the so-called blood-brain barrier.Multiple sclerosis: A riddle of the blood-brain barrier solved - Read more

Low-frequency magnetic fields and development of Alzheimer's disease

Photo: Microscope image [09/04/2015] Low-frequency alternating magnetic fields such as those generated by overhead power lines are considered a potential health risk because epidemiological studies indicate that they may aggravate, among other things, neurodegenerative disorders. However, a recent study has produced no evidence that these fields can cause exacerbation or accelerated disease development in relevant mouse models.Low-frequency magnetic fields and development of Alzheimer's disease - Read more

Photo: Measuring tape and pills [30/03/2015] Medication used to treat patients with type II diabetes activates sensors on brain cells that increase hunger, causing people taking this drug to gain more body fat, according to researchers at Georgia State University, Oregon Health and Science University, Georgia Regents University and Charlie Norwood Veterans Administration Medical Center.Why drug for type II diabetes makes people fat - Read more

Neurons: Regeneration in a hostile environment

( Source: MEDICA.de )

Photo: Cross section of rat spinal cord [16/03/2015] Damage to the spinal cord rarely heals because the injured nerve cells fail to regenerate. The regrowth of their long nerve fibers is hindered by scar tissue and molecular processes inside the nerves. An international team of researchers now reports that help might be on the way from an unexpected quarter.Neurons: Regeneration in a hostile environment - Read more
