12 Bizarre Mental Disorders That Will Leave You Speechless


This is a psychological disorder where the sufferer believed himself/herself to be an ox or a cow. This mental illness usually starts out as a dream and later turns into a full blown delusion.

It is believed that Nebuchadnezzar, King of the Neo-Babylonian Empire suffered from this condition due to the Book of Daniel where it states that he “was driven from men, and did eat grass as oxen.” This condition can reportedly be induced by hypnotism.

Foreign Accent Syndrome

The first record of foreign accent syndrome (FAS) was reported in 1907 and the rare medical condition is often triggered by head trauma, stroke or developmental problems. The disorder causes the sufferer to change from their native speech to a foreign accent.

According to the Foreign Accent Syndrome Support website, “FAS has been documented in cases around the world, including accent changes from Japanese to Korean, British English to French, American-English to British English, and Spanish to Hungarian.”


Apotemnophilia is also known as amputee identity or body integrity identity and is presumably a neurological disorder in which a person has the overpowering desire to amputate healthy parts of their body. Sufferers will either amputate their limbs or ask others (maybe a surgeon) to do it for them. When others are unwilling to perform this task the sufferer often attempts to irrevocably damage the limb themselves, requiring formal amputation.

Cognitive behavioral and aversion therapies have been tried as treatment option for patients.
