This type of LPA allows your attorney to make decisions about matters such as your medical treatment, your diet, where you live and how you spend your time. Unlike the LPA for property and financial affairs, your attorney can only use it after you have lost the mental capacity to make those decisions yourself. Your attorney cannot make decisions about life-sustaining treatment unless you specifically allow this in the LPA. Life-sustaining treatment includes ventilation to help with breathing, feeding through a tube and resuscitation.
