Brain-injured patients currently in Memory Hack Review  a vegetative state have been found to have more active brains that originally thought according to recent studies.The study examined patients who have been diagnosed in a vegetative state where they are alive, but are void of any sense of awareness. Around 20,000 Americans are considered to be in a vegetative state. Between 100,000 and 300,000 Americans are afflicted have been diagnosed with a minimally conscious state, that, although less severe, still causes patients to have intermittent or impaired awareness.

The study, published in the New England Journal of Medicine, compared brain-injured patients' brain activity to a normally functioning brains when placed in a functional Magnetic Resonance Imaging (fMRI). Patients were given careful instructions to imaging playing tennis or exploring their home. The majority of test subjects were unresponsive to the stimuli, however a significant number of patients had brain activity that mirrors healthy brain activity.

The research found that some patients - one man in particular - could answer detailed questions about his life prior to his brain injury by alternating his thoughts - thinking of tennis when responding "yes" or thinking of exploring his home when answering a "no" question. Although the patients could not communicate in any fashion with his or her body physically, they were able to correctly answer yes-or-no questions.

The possible implications associated with the research astounded Adrian Owen, the lead neuroscience researcher from the University of Cambridge. Future diagnoses and brain injury treatments could be greatly impacted by the results. Owen maintains that additional research is needed, but is excited at the prospect that technology could help some patients communicate, even if only to notify caregivers of pain or discomfort.The study rehashes the case of Terry Schiavo, who was left in a vegetative state due to oxygen deprivation - however the researchers found the brain activity was only apparent in patients whose injuries were sustained from head trauma. Schiavo became headline news in 2005 when a family dispute to remove her feeding tube turn required congressional intervention.
