Remotely delivered information, training and support for informal caregivers of people with dementia

Remotely delivered interventions including support, training or both, with or without information, may slightly reduce caregiver burden and improve caregiver depressive symptoms when compared with provision of information alone, but not when compared with usual treatment, waiting list or attention control. They seem to make little or no difference to health-related quality of life. Caregivers receiving training or support were more likely than those receiving information alone to drop out of the studies, which might limit applicability. The efficacy of these interventions may depend on the nature and availability of usual services in the study settings.
