Most of the psychological diseases are weird. Here are what I felt the most weird and strange sounding diseases of humans.
Trichotillomania:
This is a strange disease. The person who suffers from this disease has urge to pull one's hair out. Be it body hair, scalp hair, beard hair, eyelashes, nose hair or eyebrows. Abnormalities in the natural brain chemicals serotonin and dopamine may play a role in causing this disease.
Cotard's Syndrome:
The sufferer of this disease feels that he or she is dead and non-existent. The sufferer also feels that he/she lost his or her blood or internal organs; the patient even feels that the internal parts are putrefying. It can arise due to mental illness and is associated with depression.
Kleptomania:
The sufferer of this disease is forced to steal things, from paper clips to toilet rolls. They steal anything even things with no value. In some cases they aren't even ware that it is a theft. At the time of theft the patient feels pleasure or relief. The afflicted may be women in most cases. Evidences show that the abnormalities in the brain chemical serotonin may cause this disease.
Stendhal Syndrome:
This is a strange disease in which when the sufferer is exposed to a large amount of beautiful art in a short space of time he would experience dizziness, rapid heartbeat, confusion and hallucinations.
Exploding Head Syndrome:
The sufferer experiences a very loud noise as if from within his/her own head like an explosion. Usually this occurs within two hours of falling asleep but not due to a dream. Patients may feel fear and anxiety accompanied by increased heart rate. Some physicians suggest that there is a correlation with stress and extreme fatigue.
Capgras Delusion:
In this disease, the sufferer becomes convinced that a family member usually spouse has been replaced by an identical looking imposter. He or she refuses to sleep with the imposter. Some victims even second guess their own reflections in the mirror. Some Researchers say this is due to brain damage from a stroke or drug overdose and others say that it is followed after accidents that cause damage to the right side of the brain.
Pica:
This disease creates an urge to eat things other than food. Sufferers eat substances such as paper, clay, dirt, glue, coal, even feces and lint. Some Researchers believe that it is due to mineral deficiency, but others say real cause and cure is yet to find.
Genital Retraction Syndrome:
Genital Retraction Syndrome causes the victims to become panicked and frantic. In this disease males think their penis is shrinking, retracting and disappearing into abdomen; if it is in the case of females, they think breasts are retracting into the body. Sometimes sufferers believe that it is due to witchcraft.
Latah:
This disease is mainly found in adult women. The sufferer may lose control of their behavior; mimic the speech and actions of the people around them. They obey the commands given to them. For example if they are given a command to hit anybody they will obey it instantly. They actually don't know what they are doing.
Jerusalem Syndrome:
This disease is a form of religious psychosis sparked by a visit to Jerusalem. It is not confined to any one religion. Sufferers may believe that they are the prophets of the Lord and indulge themselves in parading around delivering their own sermon, obsessing about virtue and ask sinners to repent their sins. This syndrome disappears after a few weeks or when the tourists leave the place.
