Capgras delusion has more to it than just believing that a loved one has been replaced by an impostor. This can also be considered as a delusional misidentification (Lambert, Katie). It also used to be considered a rare disorder, but now, "medical professionals are beginning to think that perhaps it isn't so rare after all" (Lambert, Katie). This could be because critics used to just stereotype people with this disorder as crazy or insane, but now, scientists and doctors are actually looking into this and finding, real, medical causes for this condition. The first people to actually describe Capgras syndrome were the French doctors Joseph Capgras and Jean Reboul-Lachaux, and it is clearly visible that the disorder was named after Joseph Capgras (Lambert, …show more content…

That is the less reliable theory in my opinion because it has been proven faulty in some circumstances by Ramachandran. One of Ramachandran's patients came to him and said that his dog looked exactly like his real dog, but it was not his real dog, Fifi (Ramachandran, Vilayanur). He knew that this patient did not have sexual urges for his dog, and thus, the Freudian theory is not true in all cases (Ramachandran, Vilayanur). After he found this, he started to develop a theory of his own. The process of vision goes through the eyes, to the fusiform gyrus where facial recognition occurs, and then to the amygdala, where these faces are associated with emotions (Luque, Roberto Barroso). In Ramachandran's theory that he developed with William Hirstein, he believes that in an accident involving head trauma, somewhere between the fusiform gyrus and the amygdala is cut, causing the brain to no longer associate faces with emotions (Ramachandran, Vilayanur). One of Ramachandran's patients, David,
