Disorders That Totally Mess With Your Perception of Reality

Capgras Delusion

Imagine a scenario where someone you know suffers a traumatic head injury in an accident but luckily survives. Then the person wakes up and no longer believes that you are you. Instead, he thinks you’re an impostor. This is known as the Capgras delusion and is believed to occur after someone sustains damage to the superior temporal sulcus, an area in the brain believed to be important in attributing emotional feelings to a person.
