This study examines factors related to sleep disturbances, and the dyadic sleep relationship, in a convenience sample of 29 persons with Parkinson disease (PD) and spouse carer dyads living in regional Queensland. Carers completed questionnaires on sleep, depression, anxiety, carer burden, and well-being. Regarding carers, 66% reported sleep disturbances related to nocturnally care demands. Less than half of informal carers with a disturbed sleep had informed a health professional of this problem. Medication was the most commonly advised sleep intervention (44%). Sleep disturbances in informal carers correlated with increasing carer burden, depression scores, anxiety scores, poor quality of life, negative cognitions related to their sleep disturbance, and poor sleep hygiene. Regarding patient-carer dyads, 59% reported both the individuals having problematic sleep disturbances. Patient sleep disturbance correlated with informal carer increase in depression and anxiety scores, and poor carer burden. Informal carer’s sleep disturbance correlated with patient anxiety scores and severity of complications from PD therapy. Evidence-based sleep interventions addressing such dyads in rural areas warrant future study.
