Dementia and caregiver burden: A three-year longitudinal study

Area of Science:

• Gerontology
• Neuroscience
• Public Health

Background:

• Dementia significantly impacts caregivers, with mixed longitudinal data on burden trajectories.
• Understanding caregiver burden is crucial for developing effective support strategies.

Purpose of the Study:

• To examine the 3-year trajectory of caregiver burden in dementia.
• To identify predictors of caregiver burden over time.

Main Methods:

• Recruited 781 dementia patients from Australian memory clinics.
• Collected longitudinal data on caregiver burden, patient cognition, function, neuropsychiatric symptoms, services, and medications over 3 years.

Main Results:

• Clinically significant caregiver burden rose from 47.4% to 56.8% over 3 years.
• Burden increased for caregivers of patients without services but remained stable for those with services or in residential care.
• Patient neuropsychiatric symptoms, lower function, fewer medications, lack of driving ability, and female caregiver sex predicted higher burden.

Conclusions:

• High caregiver burden is prevalent and increases over time, particularly for those without access to services.
• Patient clinical characteristics, service utilization, and caregiver sex are key predictors of burden.
• Identifying at-risk caregivers through these predictors can inform targeted interventions.
