"I Got Laughed at for the Shuffle Noise I Make": Parkinson's Disease and Stigma.

People with Parkinson's disease (PD) are at risk for stigma. The stigma theory suggests four stigma types: public stigma, self-stigma, stigma by association, and structural stigma. The purposes of this study were to understand how people with PD and caregivers perceived and experienced stigma, review the literature and scan social media for evidence of stigma and PD, and examine the interrelationships between stigma types.
