Impaired decision-making may contribute to motor symptoms in Parkinson's disease
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. This 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. Ref.

Monkeys with Parkinson's disease benefit from human stem cells. Japanese neurosurgeons report two new strategies to improve outcomes of iPS cell-based therapies for Parkinson's disease in monkey brains. The findings are a key step for patient recruitment of the first iPS cell-based therapy to treat neurodegenerative diseases. Source 5f.
