Caregiver burden in Alzheimer's disease patients in Spain.

BACKGROUND
Alzheimer's disease constitutes one of the leading causes of burden of disease, and it is the third leading disease in terms of economic and social costs.


OBJECTIVE
To analyze the burden and problems borne by informal caregivers of patients who suffer from Alzheimer's disease in Spain.


DATA AND METHODS
We used the Survey on Disabilities, Autonomy and Dependency to obtain information on the characteristics of disabled people with Alzheimer's disease and the individuals who provide them with personal care. Additionally, statistical multivariate analyses using probit models were performed to analyze the burden placed on caregivers in terms of health, professional, and leisure/social aspects.


RESULTS
46% of informal caregivers suffered from health-related problems as a result of providing care, 90% had leisure-related problems, and 75% of caregivers under 65 years old admitted to suffering from problems related to their professional lives. The probability of a problem arising for an informal caregiver was positively associated with the degree of dependency of the person cared for. In the case of caring for a greatly dependent person, the probability of suffering from health-related problems was 22% higher, the probability of professional problems was 18% higher, and there was a 10% greater probability of suffering from leisure-related problems compared to non-dependents.


CONCLUSIONS
The results show a part of the large hidden cost for society in terms of problems related to the burden lessened by the caregivers. This information should be a useful tool for designing policies focused toward supporting caregivers and improving their welfare.
