It's frightening to care for someone you don't understand.  People living with dementia (PLWD) are themselves often filled with fear and anxiety and express themselves in ways that are difficult for others to comprehend.   For a family member or professional who is helping  persons who are themselves trying to cope with the cognitive changes going on in their brains, it is a domino effect that carries over to care partners. Fear, anxiety, guilt, and feeling very frustrated in not having the tools to better communicate and respond to  stress reactions leave caregivers feeling helpless.
