n psychiatry, derailment (also loosening of association, asyndesis, asyndetic thinking, knight’s move thinking, or entgleisen) refers to a pattern of discourse (in speech or writing) that is a sequence of unrelated or only remotely related ideas. The frame of reference often changes from one sentence to the next.[1][2] Examples:

* “The next day when I’d be going out you know, I took control, like uh, I put bleach on my hair in California.”—given by Nancy C. Andreasen[3]
* “The traffic is rumbling along the main road. They are going to the north. Why do girls always play pantomime heroes.”—given by Carl Schneider[2]

Formal thought disorder

In psychiatry, thought disorder or formal thought disorder is a term used to describe a symptom of psychotic mental illness.

It describes a persistent underlying disturbance to conscious thought and is classified largely by its effects on speech and writing. Affected persons may show pressure of speech (speaking incessantly and quickly), derailment or flight of ideas (switching topic mid-sentence or inappropriately), thought blocking, rhyming or punning or ‘word salad’ when individual words may be intact but speech is incoherent.
Subtypes in detail
Pressure of speech

An increase in the amount of spontaneous speech compared to what is considered customary.
Distractible speech

During mid speech, the subject is changed in response to a stimulus. e.g. “Then I left San Francisco and moved to… where did you get that tie ?”
Tangentiality

Replying to questions in an oblique, tangential or irrelevant manner. e.g. “What city are you from ?”, “Well, that’s a hard question. I’m from Iowa. I really don’t know where my relatives came from, so I don’t know if I’m Irish or French”.
Derailment

Ideas slip off the track on to another which is obliquely related or unrelated. e.g. “The next day when I’d be going out you know, I took control, like uh, I put bleach on my hair in California”.
Incoherence (word salad)

Speech that is unintelligible due to the fact that, though the individual words are real words, the manner in which they are strung together results in incoherent gibberish, e.g. the question “Why do people believe in God?” elicits a response like “Because make a twirl in life, my box is broken help me blue elephant. Isn’t lettuce brave? I like electrons, hello.”
