Anxiety drug can treat restless legs syndrome, improve sleep

Anxiety drug can treat restless legs syndrome, improve sleepWashington, Apr 30 : A drug, called pregabalin-commonly used to treat seizures and anxiety-has now been implicated as an effective treatment for restless legs syndrome (RLS), according to a study.

The 12-week study involved 58 people with RLS, out of which, 30 received the drug pregabalin and the rest received placebo.

The researchers performed sleep studies at the beginning and end of the research.

Almost two-thirds of the people who took pregabalin were found to have no RLS symptoms while taking the drug.

Brain can recognize objects faster than previously believed

 Brain can recognize objects faster than previously believedWashington, Apr 30 : Humans have an inherent ability to recognize faces and other objects with just a glimpse, and now researchers have found that this ability to visually process images is much faster than it is believed.

Taking advantage of brain mapping in patients about to undergo surgery for epilepsy, researchers at Children''s Hospital Boston, have for the first time showed that the brain, at a very early processing stage, can recognize objects under a variety of conditions very rapidly.

Intervention proves effective in increasing correct breast self-exams

Intervention proves effective in increasing correct breast self-examsWashington, April 30 : In a new study, researchers have found that a brief intervention program boosted the number of women correctly performing breast self- exams by tenfold.

The Kaiser Permanente Center for Health Research study is one of the first to show intervention programs can be effective in increasing breast self-exams.

Scientists identify ‘molecule trio’ that kills neurons in Parkinson''s

parkinsons diseaseWashington, Apr 30 : In a novel study, researchers at Columbia University Medical Centre have identified a trio of molecules that are responsible for killing brain cells in Parkinson’s patients.

They have showed that three molecules – the neurotransmitter dopamine, a calcium channel, and a protein called alpha-synuclein – act together to kill the neurons.

The symptoms of Parkinson''s – including uncontrollable tremors and difficulty in moving arms and legs – are blamed on the loss of neurons from the substantia nigra region of the brain.

How the brain handles words

What brain activity looks like when one anticipates any actionWashington, Apr 30 : How the brain gives meaning to letters on a page has been a mystery for scientists. Now, a new study has tried to solve the puzzle.

Neuroscientists at Georgetown University Medical Center have found that an area known to be important for reading in the left visual cortex contains neurons that are specialized to process written words as whole word units.
