Document Summary
Capgras syndrome: disconnect between the lateral fusiform gyrus (your ability to identify their face) and the amygdala , insula ( the emotional response). Makes the delusional belief that this person must be an imposter because you recognize them but do not feel the emotion you usually would. Impaired feelings of familiarity of loved ones are the outcome of the decoupling of the brain representation of the face from responses in the autonomic nervous system ( visceral response") When we see someone we know/love we have a unique physiological response in things like heart rate, and facial expression, skin conductance. Show no signs of difference in emotional response between those who they know and who they don"t. Form of dementia that impairs our semantic memory, things like facts. Selective loss in both verbal and non-verbal domains. Usually associated with frontotemporal dementia (around 20% of ftd patients) Contrasts with ad in which loss of episodic memory is more prominent.
