What the GDPA does for your assets, the Advance Health Care Directive (AHCD) does for your person.
It authorizes someone (your agent) to make health decisions for you when you cannot due to incapacity.
The document contains instructions and wishes that you have directed that the agent follow. An example of this is that you may wish all artificial respiration, feeding and other items that would keep you alive to be shut down if it were determined that you are in a persistent vegetative state. A lot of complicated language that means shut off all the tubes that keep me alive if I am a vegetable (permanently, that is).
As we age, we all run the risk of dementia and Alzheimer’s and this document names the person that you would want to be in charge of your person. They would decide where you would live and of course make health care decisions for you.
