What do folks with late-stage Parkinson's disease die from? The answer may change how we care for the final years of life. Aspiration pneumonia occurs when food, liquid or saliva enters the lungs instead of the stomach. It is one of the most feared complications of swallowing difficulties and can be life threatening. Rosqvist and colleagues describe in a new paper in the Journal of Parkinson's Disease the results of a remarkable decade long study following 107 individuals living w/ late stage Parkinson's disease and examining mortality, causes of death and factors associated w/ survival. Key points: - Just over half of participants were alive three years after entering the late stage of Parkinson's disease, about one third were alive at five years and only 15% were alive at seven years. - Aspiration pneumonia was the leading cause of death, accounting for 34% of deaths and respiratory causes together accounted for more than half of all deaths. - Worse motor symptoms, cognitive impairment and depressive symptoms were independently associated w/ higher mortality risk. My take: This study reminds us that Parkinson's disease is not simply a movement disorder. In the late stages, swallowing, cognition, mood and function become just as important as tremor or slowness. We spend tremendous time discussing gait and medications, however perhaps we should spend even more time discussing swallowing, advance care planning and preserving quality of life. Here are 5 points that resonated w/ me: 1- Swallowing difficulties deserve routine screening in Parkinson's disease and especially in later stages of the disease. 2- Aspiration pneumonia is frequently preventable through earlier recognition, speech and language therapy interventions and caregiver education. 3- Depression was independently associated w/ mortality risk, reminding us that mood symptoms matter and deserve aggressive treatment. 4- Parkinson's care should increasingly integrate palliative care principles long before the final months of life. 5- The goal in late-stage Parkinson's disease is not simply adding years to life, but adding comfort, dignity, connection and quality to those years that remain.
