… Is a fascinating and utterly bizarre disorder where patients deny their disability. For instance, one out of twenty patients who suffer a complete paralysis of the left side of their body, as a result of a stroke in the right hemisphere, deny it. This is despite the fact that they are healthy and intelligent in every other sense.
What’s even more astonishing is that some of these patients not only deny their own paralysis but also the paralysis of other patients! Such cases are thought to be connected with mirror neurons - special neurons in our brain that not only fire when we ourselves perform an action but also when we watch someone else perform it.
