Abstract:

Mild cognitive impairment (MCI) in Parkinson’s disease (PD) includes deficits in theory of mind (ToM). However, associations between ToM and caregiver burden and distress are still unclear. The objective of this pilot study was to preliminarily explore the relation between ToM and caregiver burden and distress in a sample of PD-MCI patients. Twelve PD-MCI patients were evaluated on a ToM task (Faux Pas), whereas their caregivers were assessed on caregiver burden (Zarit Burden Interview-12 items) and distress (Neuropsychiatric Inventory–Distress). Cognitive ToM was significantly associated with caregiver distress, but caregiver burden was associated with the severity of patient psychiatric symptoms.

Résumé :

RÉSUMÉ :

Altération de la théorie de l’esprit dans des cas de maladie de Parkinson et impact sur les personnes soignantes : une étude pilote.

Les troubles cognitifs légers (TCL) qui affectent les patients atteints de la maladie de Parkinson (MP) peuvent aussi inclure des déficits à ce qu’on appelle la « théorie de l’esprit » (TE ou theory of mind). Cela dit, les associations qui peuvent exister entre, d’une part, la TE et, d’autre part, le fardeau et la détresse psychologique des personnes soignantes demeurent encore méconnues. L’objectif de cette étude pilote a donc consisté à explorer ces associations dans le cas d’un groupe de patients atteint de la MP et de TCL. Au total, douze d’entre eux ont été évalués en fonction d’une tâche relevant de la TE et d’un test dit de « faux pas » tandis que les personnes soignantes, elles, ont été évaluées en ce qui regarde leur fardeau (Short Form Zarit Burden Interview ou ZBI-12) et leur détresse psychologique (Neuropsychiatric Inventory, détresse psychologique). Ainsi, la TE de nature cognitive s’est révélée significativement associée à la détresse psychologique des personnes soignantes alors que leur fardeau a été plutôt associé à la gravité des symptômes psychiatriques des patients.
