What is the term for speech that is inferred from a person's speech and includes derailment, tangentiality, or incoherence?

• A. Delusions of Control
• B. Grossly Disorganized or Abnormal Motor Behavior (Catatonia)
• C. Negativism
• D. Disorganized Thinking (Speech)

Answer: (D)

Disorganized thinking is a disturbance in the form of thought that shows up in speech. When thinking is fragmented, speech can derail, drift off on tangents, or become incoherent. Derailment means topics jump from one idea to another without logical connection; tangentiality means responses wander off-topic and don’t answer the question; incoherence can appear as jumbled or nonsensical speech. These features reflect a formal thought disorder, where the problem is in how thoughts are organized, not in what the person believes. This distinguishes it from delusions (false beliefs), catatonia (motor symptoms), or negativism (opposition or lack of response). So the accurate term for speech patterns like derailment, tangentiality, or incoherence is disorganized thinking (speech).
