The Seven Craziest Mental Diseases
The human being is a curious creature and its mind is even curiouser. Here are the seven craziest mental diseases that can plague the mind:
Autophagia

Autophagia is a mental disease in which the sufferer is compelled to inflict pain on themselves. The twisted part is that the pain comes in the form of biting and/or devouring portions of their body. The disease may be caused by severe sexual anxiety sometimes combined with schizophrenia or psychosis.
Amputee Identity Disorder

This is a neurological and psychological disorder in which a person feels they would be happier living life as an amputee. The disorder is usually accompanied by the desire to amputate a healthy limb in order to achieve their goals.
Oniomania

Yes, being a shopaholic is actually a mental disease scientifically known as Oniomania. The disease refers to a person’s compulsive desire to shop, which is characterized by a vicious circle of negative emotions that lead the sufferer to purchase something.
Cotard’s Syndrome

Cotard’s Syndrome – also known as Walking Corpse, nihilistic or negation delusion – is a rare neuropsychiatric disorder. The disorder is characterized by a person holding the delusional belief that he or she is dead or does not exist and can include delusions of immortality.
Clinical lycanthropy

Clinical lycanthropy is a rare psychiatric syndrome characterized by the delusion that the individual can or has transformed into an animal. Those affected by the disorder often start behaving like animals – crying, grumbling or creeping – as well.
Paris Syndrome

The extremely bizarre Paris Syndrome is a condition exclusive to Japanese tourists. In fact, around a dozen suffer from it while visiting the city of lights every year. The syndrome essentially is a very severe form of “culture shock” that polite Japanese tourists face when confronted by “rude” French culture.
Diogenes

Diogenes is a syndrome named after the famous ancient Greek philosopher who lived in a wine barrel and promoted ideas of nihilism and animalism. It describes a disorder characterized by extreme self-neglect, reclusive tendencies, and compulsive hoarding. It is found mainly in old people and is associated with senility.
