Charcot–Wilbrand syndrome
Charcot–Wilbrand syndrome (CWS) is dream loss following focal brain damage specifically characterised by visual agnosia and loss of ability to mentally recall or "revisualize" images. The name of this condition dates back to the case study work of Jean-Martin Charcot and Hermann Wilbrand, and was first described by Otto Potzl as "mind blindness with disturbance of optic imagination".
