A new Yale University study shows that a depletion of a class of dopamine-producing neurons is also the cause of this deficit and it occurs in the prefrontal cortex associated with higher cognitive functions - not just as areas of the brain associated with movement. The findings published in the journal Proceedings of the National Academy of Sciences may help explain other cognitive problems associated in late stage Parkinson's.
