Impaired Decision-making May Contribute to Motor Symptoms in Parkinson's Disease
UCLA researchers have discovered that people with Parkinson's disease have a form of impaired decision-making that may be a major contributor to the movement problems that characterize the disease. The finding suggests that the neurological factors underlying Parkinson's, which currently affects nearly 1 million people in the United States, may be more complex than commonly believed. The study also could pave the way for strategies to detect Parkinson's earlier in its course.

Eliminating HIV Is Possible; UCLA, Danish Researchers Explain How
Worldwide, about 35 million people are living with HIV. The World Health Organization and the Joint United Nations Programme on HIV/AIDS plan to use an approach called "treatment as prevention" to eliminate the global pandemic, which the WHO says will have occurred when only one person out of 1,000 becomes infected each year. Now, a nearly two-decade analysis by researchers from UCLA and Denmark yields the first proof that the approach could work.
