Symptom progression in advanced Parkinson's disease: Dyadic perspectives.

This qualitative descriptive study investigated the self-reported symptoms of people with advanced Parkinson's disease. Fifteen dyads (person with Parkinson's and family caregiver) participated in two semi-structured interviews over a six-month time period; content analysis was used to explore the progression and new onset of symptoms. Reported symptoms in descending order included gait deterioration, falls, speech impairment, cognitive decline, functional decline, gastrointestinal and genitourinary changes, and swallowing impairment. The presence of multiple, compounding symptoms present challenges for maintaining safety in the home, highlighting the need for in-home services to assist with symptom management. Change in self-reported symptom experience was not significantly different after a six-month time frame. Symptom progression in advanced Parkinson's disease may take longer than six months to appreciatively manifest. Therefore, future research should explore the progression of advanced Parkinson's disease longitudinally over of period of time that exceeds six months.
