PET Scans Uncover More Information About Brain Activity in Vegetative Patients

An article in The New York Times explains that a new study found that PET scans may provide useful information for people in vegetative states. The study “found that a significant number of people labeled vegetative had received an incorrect diagnosis and actually had some degree of consciousness and the potential to improve.” Researchers used both PET scans and MRI scans to assess the brain activity of 41 vegetative patients, and “Over all, PET scans were a better measure than M.R.I. scans. Researchers say the findings support the idea that some patients who appear vegetative have some level of consciousness that they cannot show — perhaps low, but real — and the potential to recover.”
