Type: article
Abstract: ABSTRACT Background Cognitive impairment is common and disabling in Parkinson's disease and may progress to dementia in up to 80% of individuals. Non‐pharmacological interventions are increasingly studied, but their modalities, delivery characteristics and clinical applicability remain unclear. Aim To map and synthesise evidence on non‐pharmacological interventions for cognitive impairment in Parkinson's disease, characterise intervention modalities and delivery features and examine relevance to nursing practice. Design Scoping review. Methods Following Arksey and O'Malley's framework, two reviewers independently screened records and extracted data; discrepancies were resolved by consensus. Data were synthesised descriptively using an intervention modality and delivery characteristics framework. Data Sources PubMed, Scopus, Web of Science, Cochrane Central Register of Controlled Trials, Cumulative Index to Nursing and Allied Health Literature and Ichushi‐Web were searched from inception to October 2025. Results Seventeen studies met the inclusion criteria; most were published after 2020. Interventions included cognitive training ( n = 12) and exercise and dual‐task programmes ( n = 5). Four cognitive training interventions used technology‐assisted, home‐based platforms. Most were delivered by neuropsychologists or physiotherapists in facility‐based settings; only one was nurse‐led. Conclusions Non‐pharmacological interventions for cognitive impairment in Parkinson's disease are largely non‐invasive and involve structured cognitive, physical or technology‐assisted components. The scarcity of nurse‐led interventions highlights a critical evidence gap and underscores the need for nurse‐led and nurse‐coordinated cognitive care models. Implications for the Profession and/or Patient Care Nurses are well positioned to support, coordinate and monitor non‐pharmacological cognitive and exercise‐based interventions for people with Parkinson's disease, particularly in home‐based and technology‐assisted formats. Impact This review mapped 17 studies of non‐pharmacological interventions for cognitive impairment in Parkinson's disease and characterised their modalities and delivery features. Technology‐assisted and home‐based formats were identified as an emerging trend, although most interventions remained specialist‐led and facility‐based. The near‐absence of nurse‐led interventions highlights a critical evidence gap and an important opportunity to develop nurse‐led and nurse‐coordinated models of cognitive care.
