Poor sleep quality in caregivers is associated with increased caregiver burden in Alzheimer's disease, with female caregivers being especially vulnerable.

In a multicenter Italian study of 238 Alzheimer's disease caregiver-care recipient dyads, caregiver burden was significantly associated with snoring, daytime hypersomnolence, longer sleep latency, and use of sleep medication. Sex-stratified analysis revealed that these associations were present only among female caregivers, suggesting sex-specific vulnerability to the negative consequences of poor sleep on caregiving burden.

Participants: N/A
Duration: Not specified (cross-sectional)
Intervention: Observational study; no intervention tested.
Outcome: Caregiver burden (Caregiver Burden Inventory) and sleep characteristics (Pittsburgh Sleep Quality Index) of both caregivers and care recipients.
Effect Size: N/A
Population: 238 caregivers (65.9% women; mean age 59.6 ± 12.4 years) and 238 care recipients with Alzheimer's disease (153 women; mean age 77.5 ± 7.9 years) from Italy.

Mechanism Graph

Poor sleep quality (e.g., snoring, hypersomnolence, longer sleep latency, sleep medication use) is associated with increased caregiver burden.
↓
Female caregivers may experience greater physiological or psychological vulnerability to sleep disturbances.
↓
Sex differences in sleep architecture or stress response may amplify the impact of poor sleep on burden.
↓
Result: Female caregivers show significant associations between sleep characteristics and burden, while male caregivers do not.

Limitations

  • ⚠Cross-sectional design prevents causal inference.
  • ⚠Sleep characteristics were self-reported via PSQI, which may be subject to recall bias.
  • ⚠The study was conducted in Italy, limiting generalizability to other populations.
  • ⚠Menopausal status was mentioned but not detailed in the abstract, so its specific role remains unclear.

Frequently Asked Questions

What sleep problems are associated with caregiver burden in Alzheimer's disease?▼

The study found that snoring, daytime hypersomnolence, longer sleep latency, and use of sleep medication were associated with higher caregiver burden.

Are there sex differences in the relationship between sleep and caregiver burden?▼

Yes, the associations between sleep characteristics and caregiver burden were significant only among female caregivers, indicating that women may be more vulnerable to the negative effects of poor sleep on burden.

What was the sample size and design of the study?▼

The study included 238 caregivers and 238 care recipients with Alzheimer's disease. It was a multicenter observational study conducted in Italy.

What tools were used to measure sleep and caregiver burden?▼

Sleep quality was assessed using the Pittsburgh Sleep Quality Index (PSQI), and caregiver burden was measured using the Caregiver Burden Inventory.
