Background: Apathy, one of the most common neuropsychiatric symptoms in Parkinson's disease (PD), has been associated with reduced daily functioning, cognition, treatment compliance, quality of life, and increased caregiver burden and distress, among other outcomes.
Objectives: The purpose of the present study was to develop and gather pilot data on the feasibility, acceptability, and efficacy of the Parkinson's Active Living (PAL) program, to our knowledge, the first behavioral treatment specifically designed to target apathy in patients with PD. The Parkinson's Active Living is a primarily telephone-based, 6-week activity scheduling and monitoring intervention that incorporates external cueing to target disease-related self-generational deficits to reduce levels of apathy in nondemented, highly apathetic patients with PD.
Methods: Participants aged 44 to 86 years (mean = 66, SD [standard deviation] = 10.7) ranging in disease duration from <1 to 23 years with elevated apathy (Apathy Evaluation Scale >35) were enrolled in a 1-arm trial and tested at 3 time points (baseline, posttest, and 1-month follow-up).
Results: Feasibility aspects (ie, acceptability, demand, implementation, practicality, adaptation, integration, and expansion) and efficacy of PAL program are reported. Matched pairs t tests showed a medium to large effect of treatment on patient apathy (52% showing ≥1 SD improvement), depression (33% showing ≥1 SD improvement), and quality of life at posttest, with improvements in apathy and depression maintained at follow-up.
Conclusions: The program may hold promise as an effective nonpharmacological intervention for apathy in PD. Implications and future directions are discussed. Randomized controlled trials are needed.
