Background: Confabulations are often observed in patients with Alzheimer's disease (AD) and can increase family caregivers’ burdens. Previous studies have focused on the relationship between confabulation and cognitive ability. However, few studies have investigated the association between confabulation and familial factors. Here, we aimed to examine whether confabulation relates to familial factors, such as the level of family caregivers’ expressed emotion or the level of functioning of the family.
