Functio laesa

Last updated

Functio laesa, simply known as dysfunction is a term used in medicine to refer to a loss of function [1] [2] or a disturbance of function. [3]

It was identified as the fifth sign of acute inflammation by Galen, who added it to the four signs identified by Celsus ( tumor , rubor , calor , and dolor ). [4]

The attribution to Galen is disputed, [3] and has variously been attributed to Thomas Sydenham [5] and Rudolf Virchow. [6]
