Up to one in four patients who are unresponsive after suffering serious brain injuries might actually still be conscious – indicating more patients may be aware of their surroundings than previously realized, new research suggests.

This state of 'hidden consciousness' is now officially known as cognitive motor dissociation (CMD), where cognitive (or thinking) abilities aren't connected to motor (or movement) abilities. Researchers have been looking into CMD for several years.

However, 62 percent of an additional 112 patients who were visibly responding to instructions at the bedside didn't exhibit the expected brain signals showing responsiveness – so the researchers suggest their methods still don't detect everyone with cognitive function.

Yeah, have been in the room with a comatose person. Some people are good at just dumping out a one-sided conversation, but not me. The inclusion of the percentage of people who were clearly responsive but whose brain scans didn't indicate the expected activity is really important to take note of though. Really does need more study to refine our understanding.
