[Double dissociation between unilateral neglect and anosognosia].
We report two patients presenting with a subacute right hemisphere stroke. These cases demonstrate a double dissociation between unilateral neglect and anosognosia for hemiplegia. The first patient suffered from a severe left hemiplegia associated with severe and persisting unilateral neglect. He appeared fully aware of his motor impairment. The second patient had a severe left hemiplegia, without any major sign of unilateral neglect on clinical tests nor on behavioural assessment. Nevertheless, he presented a severe and sustained anosognosia for hemiplegia. These case reports support the assumption that anosognosia and unilateral neglect, although they are frequently associated, may rely on independent mechanisms.
