Some of these small parasites have been mutating and are now resistant to many over-the-counter medications.
Former Israeli prime minister Ariel Sharon has been in a permanent vegetative state since suffering a stroke in January 2006. But recently in tests he showed signs of brain activity.
Doctors performed brain scans on the 84-year-old Sharon while showing him pictures of random houses. When they flashed a picture of his own home, Sharon’s brain images lit up.
Sharon’s brain also responded to family voices, but not other sounds.
Does that mean Ariel Sharon is “in there” – conscious in a body that can’t move? And what does all of this mean for patients and families in similar situations?
Bioethicist Art Caplan, who heads the Division of Medical Ethics at New York University’s Langone Medical Center, says the brain test results do not mean that Sharon will wake up.
And prolonging the life of Sharon – and others like him – may be causing misery, Caplan said, if he has any awareness of being trapped in his body.
