Thats absolute and complete bullshit.
I suggest you look into the facts of the case. TS was given NUMEROUS scans and neorlogical examinations during the first 7 years.
Nobody and history has emerged out of a PVS or shown progress beyond 5 years. At the time of the hearing, TS had 7. You can't reverse the loss of synapses and synaptic structure. You simply can't. If she was brain dead 10 years ago, she's brain dead now.
