The Physician's Guide to Delusional Infestation

This unique, ground-breaking book is a comprehensive clinical guide to the psychiatric disorder of Delusional Infestation (DI). DI is a psychiatric illness characterized by patients holding a monothematic fixed belief of infestations on their skin, body, or immediate environment - a belief that is not supported by objective medical evidence. Delusional beliefs may be shared among individuals, and perceived pathogens include living organisms such as parasitic worms, bacteria, fungi, and insects.
