It is estimated that at least 50 percent of people living with Parkinson’s disease (PD) experience depression at some time during the course of their disease. The Parkinson’s Foundation Parkinson’s Outcomes Project found that taken together, mood, depression and anxiety have the greatest impact on health status, even more than the motor impairments commonly associated with the disease.

Cognitive Changes in Parkinson’s: A Complex Picture

Cognitive difficulties are among the most troubling and disabling non-motor symptoms of Parkinson’s disease (PD). Unfortunately, it is now recognized that they can also be very common as PD progresses. Some people experience mild changes even before a PD diagnosis; by 20 years after diagnosis, up to 80 percent of people with PD develop dementia.

A new study finds that cognitive impairment is a frequent and rapidly progressing symptom of Parkinson’s disease (PD). About half of the participants who had PD for an average of five years and had normal cognition at the beginning of the study developed mild cognitive impairment (MCI) within six years – about 11 years after PD diagnosis. Those few who developed MCI progressed to dementia within five more years. The results appear in the September 11 online edition of Neurology.

Uncovering the Brain Changes Responsible for Cognitive Decline in PD

According to a new study, the cognitive difficulties experienced by some people with Parkinson’s disease (PD) may arise because of neuron loss in several regions of the brain. Using brain imaging, the study finds that the same brain changes that lead to movement symptoms in PD also contribute to mild cognitive problems. But different brain changes play a role in more severe cognitive symptoms in PD. The results were published online December 15 in JAMA Neurology.
