Current Knowledge

The term “alexithymia” was coined by the late psychiatrist Peter Sifneos to describe patients who could not find the appropriate words to describe their emotional states. Literally meaning “without words for emotions” in Sifneos’ native Greek, alexithymia is a trait that overlaps with a number of medical and psychiatric disorders. Alexithymia is associated with somatic complaints such as headaches, lower back pain, irritable bowel syndrome, and fibromyalgia. It is also associated with psychiatric conditions such as anorexia nervosa, autism spectrum disorders including Asperger’s, major depressive disorder, panic disorder, post-traumatic stress disorder, and substance abuse.
