2. Quasimodo Syndrome
Quasimodo syndrome, also known as body dysmorphic disorder, is characterized by obsessive thoughts about a physical defect that either does not exist or is highly exaggerated. Patients with this disorder may constantly look in the mirror, trying to find an angle at which the defect isn't visible. They may refuse to have their picture taken due to low self-esteem. This mental disorder can be extremely dangerous and end up effecting relationships.3. Erotomania
Someone who is suffering from erotomania is sure that someone else is in love with them. This is typically someone of a higher social status, such as a celebrity. An erotomania patient believes that their imaginary admirer shows love for them through secret signals, special signs and coded messages in the media.4. Capgras Delusion
This disorder causes a person to believe that someone close to them, or even they themselves, have been replaced by a doppelganger. Someone who suffers from capgras delusion may claim that immoral actions were actually committed by their doppelganger who looks just like them.
