Communication between caregivers and their loved ones is essential so that both understand each other's roles and needs. Dementia can disrupt this flow of dialogue even before the illness has take hold of the individual. A new study conducted by researchers at Penn State and the Benjamin Rose Institute on Aging finds that even early on in the disease, "family caregivers and their relatives often do not understand each other well when it comes to the values they hold about giving and receiving care." This can have a detrimental effect on their relationship and how the care is provided and received. The five core values the study looked at were autonomy, burden, control, family and safety.
