If you're a medical professional, you'll love the show WandaVision. It's chock full of syndromes.

WandaVision was just full of syndromes: Capgras Syndrome, Fugue State, and Cotard's Syndrome. <br><br>Capgras Syndrome is when a person believes that someone close to them has been replaced by an identical imposter.<br><br>Fugue state is a rare psychological disorder in which an individual suddenly, unexpectedly, and inexplicably takes leave of their past and present life, cannot recall their past and either partial or complete adoption of a new identity.<br><br>Cotard's Syndrome is a neuropsychiatric disorder in which a person believes they are dead or do not exist. This belief is held despite being obviously alive and may be held so strongly that the person will not acknowledge themselves in a mirror or attempt to bury themselves.<br><br>(Very minor spoiler alert: this isn't actually the plot, just three episodes).
