👉 The term "idiospastic" is a medical term used to describe an abnormal or unusual response to trauma, infection, or stress. It refers to a condition in which an individual's body responds to injury or other stimuli with exaggerated and distressing symptoms similar to those of an idiopathic disease but without the characteristic signs and symptoms typical of such diseases. Idiospastic reactions can be caused by various factors including infections, injuries, trauma, certain medications, and stress.
