We read with great interest the study by Tarolli et al.,1 which explored the burden of disease in Parkinson disease (PD) by evaluating the prevalence of nonmotor symptoms and their association with quality of life. The authors selected nonmotor symptoms based on literature review, expert opinions, and patient interviews. We note that apathy, which has major consequences for patients and carers, was not included as a relevant nonmotor symptom in their study. We performed a subcohort analysis of 60 patients from a study of pain in PD in 110 outpatients (PaCoMo-study, registered trial number: NL6311402917 [toetsingonline.nl]). We retrospectively reviewed the medical records to check whether the clinician identified apathy in these patients in the previous year, which was the case in 15% of the patients (n = 9). Blind to those results, patients were examined with the Apathy Scale (AS).2 In total, 63.3% (n = 38) of the patients scored positive on the AS. Only 18.4% of the patients who scored positive on the AS were also classified or mentioned with apathy in the medical records by clinicians.
Apathy, an important nonmotor symptom of PD, is often missed or minimized by clinicians. When apathy is acknowledged, treatment can lead to better outcomes for patients.3
