Financial exploitation is a real problem that impacts persons living with dementia and their families. Decisional capacity is the ability to make a decision. Decisional capacity does not mean everyone agrees with the person's final decision; I can have the ability to make a decision, but may still make a poor one because I allowed emotions to affect my decision or failed to heed good advice. Decisional competence is a legal term. Competence is ultimately decided by a judge, who weighs opinions rendered by court-appointed or court-recognized experts.
