Decreasing GSE was linked to PSD, especially in patients with high baseline GSE. This effect may be due to dissatisfaction with recovery following high expectations. Early depressive symptoms and low social support predicted PSD. Early screening for depressive symptoms and focusing on self-efficacy might help to prevent later depression.

ObjectiveTo evaluate the point of view of patients with Parkinson disease (PD) on early detection and risk disclosure in the prodromal phase of PD and to derive recommendations for an ethical framework for the recruitment of prodromal PD cohorts.MethodsA standardized questionnaire to evaluate the patients' perception on early diagnosis in PD was designed by an interdisciplinary study group. After testing in a preliminary feasibility study (n = 20), the survey was performed retrospectively with patients from our clinic.ResultsA total of 101 patients with PD answered the questions. The majority of patients reported that time from onset of motor symptoms to diagnosis was burdensome, including false diagnoses and many consultations of various medical specialists. However, most of the patients evaluated early risk disclosure with skepticism. Freedom of choice and the potential of changes in lifestyle were rated as important.ConclusionAlthough patients with PD reported the time to diagnosis retrospectively as burdensome, the majority was skeptical regarding early disclosure of risk, especially with regard to the lack of pharmacologic options. Circumstances under which early detection and disclosure would have been approved by the majority of patients were (1) advice on lifestyle changes (exercise, nutrition) as potentially disease course–modifying therapy; (2) the establishment of an early diagnosis “culture,” including early clarification of the patients' wish to know; and (3) regular support and follow-up of individuals after risk disclosure.
