by Hospital for Special Surgery A national survey of male patients with lupus finds the illness has a significant impact on their physical and emotional health, yet they often do not receive support that could help them cope. Researchers at Hospital for Special Surgery (HSS) in New York City launched the nationwide survey to assess the needs of male patients...

Scientists shed new light on neural processes behind learning and motor behaviours
by eLife Researchers have provided new insight into the neural processes behind movement and learning behaviours, according to a study published today in eLife. The findings in rats reveal how the cerebral cortex, which is responsible for processing information, affects the basal ganglia, which controls motor behaviours and reinforcement learning. This could pave the way...

Why only some post-stroke survivors can ‘copy what I say’
Certain brain regions must be intact in stroke survivors with aphasia if they are to copy what another speaker says, report researchers from the Medical University of South Carolina and elsewhere in Brain MEDICAL UNIVERSITY OF SOUTH CAROLINA In an article in Brain, researchers at the Medical University of South Carolina (MUSC) and elsewhere report which...

Quadriplegics Can Grasp, Lift Objects Using Transcutaneous Neurostimulation
MEDGADGET EDITORS NEUROLOGY, REHAB Transcutaneous electrical muscle stimulation is used in a variety of clinical applications, including as a rehabilitation tool to help people with limited mobility. It is effective for maladies such as certain types of urinary incontinence, for example, but getting the muscles of the arm to move in unison and with appropriate...

Smokers and hypertensive individuals have higher risk of sudden death from brain bleed than previously believed
by University of Helsinki Contrary to the previous data, a Finnish study clarifies that smoking and high blood pressure do not protect from death in patients suffering from subarachnoid hemorrhage, the most lethal stroke subtype. In fact, subarachnoid hemorrhage kills smokers and hypertensive individuals even before they reach hospitals, and therefore, previous studies that did...

Restoring protein homeostasis improves memory deficits in Down syndrome model
by Baylor College of Medicine Down syndrome is the most common genetic cause of intellectual disability, and currently there is no effective treatment. Memory deficits are a hallmark of this condition and a study published today in the journal Science reports that the defects in a conserved stress pathway dubbed the ‘integrated stress response,’ or...

Link between inflammation and mental sluggishness shown in new study
by Beck Lockwood, University of Birmingham Scientists at the University of Birmingham in collaboration with the University of Amsterdam have uncovered a possible explanation for the mental sluggishness that often accompanies illness. An estimated 12 million U.K. citizens have a chronic medical condition, and many of them report severe mental fatigue that they characterize as...

Researchers discover crucial ‘missing link’ between breathing and cardiovascular systems
by Macquarie University A team of researchers from Macquarie University have found a crucial missing link between the parts of the brain that control breathing and those that control the cardiovascular system. The discovery provides clues to how life-threatening conditions such as hypertension develop and may ultimately lead to more effective treatments. The study, conducted...

We Know We’re Full Because Intestine’s Stretch Sensors Tell Us So
We commonly think a full stomach is what tells us to stop eating, but it may be that a stretched intestine plays an even bigger role in making us feel sated, according to new laboratory research led by UC San Francisco neuroscientist Zachary Knight, Ph.D. You may not believe it, especially heading into the holiday...

In Down Syndrome Mouse Model, Scientists Reverse Intellectual Deficits with Drugs
In a surprising finding using the standard animal model of Down syndrome (DS), scientists were able to correct the learning and memory deficits associated with the condition — the leading genetic cause of cognitive disability and the most frequently diagnosed chromosomal disorder in the U.S. — with drugs that target the body’s response to cellular...
