I get this one a lot. Lethologica, as I randomly found out, is a psychological disorder that disturbs one’s ability to articulate his/her thoughts by temporarily forgetting key words or names. The disorder was first identified by a Swiss psychiatrist. The word finds its root in the Greek word “letho”, which means forgetfulness. It also relates to the mythological river Lethe from which the shades of the dead were required to drink in order to forget their past.
