Electrodes stir man from six-year coma state
A brain-damaged man, trapped in a coma-like state for six years, has been brought back to consciousness by doctors who planted electrodes deep inside his brain.
Original article from Cosmos Online, 2 Aug 07
The method, called deep-brain electrical stimulation (DBS) has successfully roused communication, complex movement and eating ability in the 38 year-old American man who suffered a traumatic brain injury and for six years showed few signs of recovery.
His injuries left him in a 'minimally conscious state' (MCS) – a condition akin to a coma but characterised by occasional, but brief, evidence of environmental and self-awareness that coma patients lack. It's thought to currently afflict up to an estimated 300, 000 patients in the USA.
