Are you taking into account that she is on heavy duty morphine?
When my mom was on morphine, without any brain impairment, she was not responsive either.
Is she? I don't know why -- she can't feel any pain. And if she is on heavy duty morphine, then why call in a neurologist to make an assessment?
By the way, Dr. Cheshire's affidavit simply states that Terri is receiving "analgesic medication".
