It's not the same thing at all. You have obviously never known anyone with a child who is profoundly mentally disabled and not even able to respond to a parent's attention and love, a child that lies on a blanket in the living room, is fed with a bottle, and even has trouble with normal elimination of body wastes. I knew someone with a child like that, a child who was born normal, but had a reaction to the anesthesia during an operation to put tubes in his ears.
I had a son who died at the age of two and a half from a degenerative disease called Krabbes disease. For the last two years of his life, he did nothing, unable to move, unable to see, and unable to swallow, finally unable to breathe. I took care of him every night, all night, feeding him through an NG tube, changing his diapers, bathing him, and suctioning his throat when he choked on his own saliva. And when he finally took his last breath, he did so right next to me in bed.
