Abstract
When a diagnosis of dementia is made, both the individual and their family are confronted with a sudden influx of wide-ranging information. While intended to be supportive, this abundance of information can be overwhelming, and it is not clear which types are most beneficial for caregivers as they move into the care period that follows. This study examined which forms of informational support provided at the time of diagnosis are associated with reduced caregiver burden. In collaboration with dementia medical centers and certified dementia support doctors in Japan, we distributed questionnaires to family caregivers of people with dementia. A total of 159 self-administered questionnaires were returned. Caregiver burden was assessed using the short version of the Japanese Zarit Caregiving Inventory (J-ZBI_8). Regression analyses were conducted to evaluate the relationship between nine categories of information provided at diagnosis and caregiver burden, while adjusting for caregiver and care recipient characteristics as well as caregiving context. The results showed that only two types of informational support were significantly associated with a lower caregiver burden: information about dementia itself and information about local medical institutions. Other types of information, although often offered at diagnosis, did not demonstrate a measurable impact on caregiver stress. These findings underscore the importance of focusing on essential and practical information that directly helps families understand the disease and navigate available support systems. In conclusion, providing families with clear explanations about dementia and guidance on local medical resources may play a pivotal role in easing the challenges that follow diagnosis. By prioritizing these core informational needs, healthcare professionals can better support family caregivers, reduce stress, and foster more sustainable care environments in the community.
