Background: Knowledge about sleep complaints of caregivers of patients with Alzheimer’s disease (AD) andParkinson’s disease (PD) is limited, and we lack information about the relationship between caregivers’ sleepproblems and their quality of life (QoL).Methods: We evaluated subjective sleep quality and its relationship to QoL in a group of 80 caregivers ofpatients with AD (ADCG, n = 40) and PD (PDCG, n = 40), and in 150 controls. Information about nighttimecomplaints was collected using the Pittsburgh Sleep Quality Index (PSQI). QoL was measured using theMcGill QoL Questionnaire.Results: Eighteen ADCG (45%), 22 PDCG (55%), and 45 (30%) controls reported poor sleep quality. Meanglobal PSQI score of PDCG (6.25 ± 3.9) was not significantly different from that of ADCG (5.8 ± 3.5;p = 0.67). However, both PDCG and ADCG scored significantly higher than control group (4.3 ± 3.1;p < 0.01). ADCG frequently reported difficulties falling asleep (72.5%) and disturbed sleep (100%). PDCGreported reduced subjective sleep quality (80%) and increased sleep disturbances (100%). Poor sleep qualitywas associated with depressive symptoms and correlated with QoL in caregivers of both groups, particularlythe psychological symptoms domain.Conclusions: Among caregivers of patients with AD and PD, poor sleep quality is frequent and significantlylinked to QoL and depressive symptoms. Identifying the nature of sleep disturbances not only in patients butalso in their caregivers is important as appropriate treatment may lead to a better management of the needsof families coping with these patients.
