Like every profession, medicine has its own terminology to describe a wide range of symptoms, medical conditions, and psychological disorders. Most medical terms are based off their meaning in Latin or Greek. Modern medicine is also home to some pretty interesting names for actual conditions, such as Walking Corpse Syndrome, Alice in Wonderland Syndrome, and Geographic Tongue. Medical terms throughout history have given way to modern medical terms, sometimes due to political correctness. Here are five medical terms that you won’t believe were once included in the medical lexicon:

1. Moral Insanity

James Prichard first described “moral insanity” in his 1835 book, A Treatise on Insanity and Other Disorders Affecting the Mind, as “a form of mental derangement in which the intellectual faculties appear to have sustained little or no injury, while the disorder is manifested principally or alone, in the state of the feelings, temper, or habits.” Today, we refer to someone suffering from moral insanity as sociopath or a psychopath.

2. Gay-Related Immune Deficiency

Back in the early 1980s when an unknown immunodeficiency disorder was popping up in major U.S. cities, including Los Angeles and New York City, doctors had no idea what they were dealing with. After the Centers for Disease Control and Prevention published a report that described five young, previously healthy, gay men in Los Angeles who developed unusual and severe infections that were the result of a deficient immune system, doctors from across the U.S. began flooding the CDC with reports of similar diagnoses. Although we now know this to be the beginning of the AIDS epidemic, health care professionals back in 1982 had a very different, and somewhat distasteful, name for acquired immune deficiency syndrome: gay-related immune deficiency.

3. Gay Bowel Syndrome

Physicians were apt to use offensive medical terms to describe a condition that affected mainly gay men even before the discovery of AIDS in the 1980s. Gay bowel syndrome was coined in 1976 to describe various sexually transmitted anorectal and colon diseases that were usually found in, but not exclusive to, homosexual men. Medical diagnoses covered under the umbrella of gay bowel syndrome included herpes, hepatitis, gonorrhea, syphilis, anal fistula, rectal ulcers, and hemorrhoids. The term was later expanded to include colorectal, colon, and rectum cancer.

4. Idiot, Imbecile, Moron

From the Latin word imbecillus, meaning weak or weak-minded, the term imbecile is actually a medical category used to describe people with moderate to severe intellectual disability. During the early 20th century, people with an IQ score between 0 and 20 were considered an “idiot,” between 21 and 50 an “imbecile,” and between 51 and 70 a “moron.” As imbecile moved from less of a medical term and more of a derogatory insult, it was removed from professional use and was replaced by “mental retardation.” However, the “moron,” “imbecile,” “idiot” IQ classification remained until the early 1970s. With President Barrack Obama’s signing of “Rosa’s Law” on Oct. 5, 2010, federal laws that referred to “mental retardation” were changed to “intellectual disability.”

5. King’s Evil

The King’s Evil, also known as scrofula, was a term used to describe lymphadenitis, an infection resulting in the inflammation of cervical lymph nodes, which is associated with tuberculosis or non-tuberculosis mycobacteria. Even more interesting than the King’s Evil is the preferred method of treatment for this condition. During the Middle Ages in England and France, people suffering from the King’s Evil were told the only sure way to cure their condition was through Royal Touch, meaning a laying on of hands by French and English monarchs.
