Unmasking Anosognosia: Revealing Hidden Brain Networks in Unawareness

Researchers identified specific brain network connections associated with anosognosia, a condition where patients are unaware of their neurological or psychiatric deficits. Using a technique called lesion network mapping, they identified separate networks linked to visual and motor anosognosia and a shared network responsible for awareness of these deficits. The shared network converged on the hippocampus and precuneus, both associated with memory.
