Old Names for Illnesses
What old illness names actually mean
Parish registers — much like our grandparents' family charts — tend to record more or less every possible detail about a deceased person. Besides the date of death or burial, you'll often find information on surviving relatives (children/spouse), occupation, and the cause of death or illness. That's certainly helpful, but it also means we have to get to grips with the meaning of old illness names. That's why I've researched a few "translations" online for this page.
The archaic medical terminology found in old records often referred to the symptoms of an illness rather than the illness itself. Take, for example, the term "Engbrüstigkeit" ("tight-chestedness") for asthma. As we'd describe asthma today, it's typically marked by breathlessness, coughing and a feeling of tightness in the chest — so the symptoms can often be matched up to illnesses known today.
You'll also come across many Latin illness terms. Cachexia (or "Kachexie") still means exactly what it did then: wasting, or pathological weight loss, accompanied by loss of appetite and strength — a symptom of many serious conditions such as anorexia, cancer, or metabolic disorders.
