Patients with early Parkinson disease appear to have similar overall levels of disability and quality of life six years after beginning treatment with either levodopa or a dopamine agonist, according to a report posted online today that will appear in the May print issue of Archives of Neurology, one of the JAMA/Archives journals. However, persistent differences are seen in some effects of these medications, including motor symptoms, fluid build-up and sleepiness.
A study published online today in the Archives of Neurology involving two common drugs used to treat early-stage Parkinson's disease shows that, while the drugs each have advantages and disadvantages, the overall impact tends to even out over a long period of treatment.

The results can be found in the March issue of Psychology of Addictive Behaviors, published by the American Psychological Association.
A new University of Central Florida study may explain why children with attention deficit hyperactivity disorder move around a lot – it helps them stay alert enough to complete challenging tasks.
In studies of 8- to 12-year-old boys, Psychology Professor Mark D. Rapport found that children with and without ADHD sat relatively still while watching Star Wars and painting on a computer program.
WINSTON-SALEM, N.C. – A new study at Wake Forest University School of Medicine reveals that many N.C. high schools are not adequately prepared to handle the immediate medical needs of a student or employee who suffers a sudden cardiac arrest on campus. The findings were used to support a new statewide program to place automated external defibrillators (AEDs) in high schools.
SAN DIEGO, Calif. (March 9, 2009)—Osteoplasty—a highly effective minimally invasive procedure to treat the painful effects of metastatic bone disease by injecting bone cement to support weakened bones—provides immediate and substantial pain relief, often presenting individuals who are suffering terribly with the miraculous so-called "Lazarus effect," according to researchers at the Society of Interventional Radiology's 34th Annual Scientific Meeting. Interventional radiologists often couple osteoplasty with heat or cold treatments to kill tumor nerves, if needed.

Eating fish once a week was enough to increase combined, verbal and visuospatial intelligence scores by an average of six per cent, while eating fish more than once a week increased them by just under 11 per cent.
Children of older fathers perform less well in a range of cognitive tests during infancy and early childhood, according to a study published this week in the open-access journal PLoS Medicine.
