A living will, also called a treatment directive, is a type of
advance directive that documents personal wishes about end-of-life medical
treatment in case decision-making or communication abilities are lost. A living
will specifies the conditions under which certain kinds of treatment or
life-support measures would or would not be wanted.
A living will can be changed or revoked at any time and will not
take effect until a person is no longer able to make or communicate decisions.
Copies of living wills should be given to and discussed with a person's health
professional and family members.
