For some time now Brenda had been suffering seizures that were becoming increasingly severe. Her doctor had warned her that she would ultimately become profoundly disabled. A month before the seizure that left her completely disabled, Brenda signed an advance directive giving her mother a power of attorney to stop treatment if she became incapacitated. But to no avail: after her next seizure, the hospital put Brenda on a ventilator and tubefed her during a twomonth coma, despite her mother's insistence that Young did not want life support.

Question: Should Brenda and her mother be able to recover damages from the hospital that treated Brenda against the instructions of her mother? On what legal theories might Brenda and her mother base their claims?
