Examination and Disturbance of Thinking — PROCESS / FORM (MSE)
1. Overview — Form/Process vs. Content of Thinking
Gajdos (Psychopathology II) splits thought disorders into two great branches, and the exam tests whether you can sort any sign into the right one:
| FORM / PROCESS (this topic, T29) | CONTENT (T30) | |
|---|---|---|
| Question it answers | HOW the patient thinks — the structure, speed and connection of ideas | WHAT the patient thinks — the belief itself |
| What is disturbed | Tempo, coherence, logical association chains, goal-direction | Truth/appropriateness of the idea |
| Examples | Flight of ideas, retardation, blocking, derailment, perseveration, neologism, verbigeration, echolalia, clang | Delusions, obsessions, overvalued ideas |
| Can the patient "conceptualize correctly"? | No — the machinery of thought is broken | Yes — machinery works, but content is false/abnormal |
- Definition of thinking (Gajdos): "the way in which a person puts together ideas and associations." A formal thought disorder (FTD) is a disturbance of that putting-together.
- Key exam trap (PSY 3.14): a delusion is CONTENT, not form. A delusional patient can have a perfectly formed train of thought — he conceptualizes correctly, the content is just untrue. Flight of ideas and logorrhoea are form. This is the single most-tested form-vs-content distinction.
- Logorrhoea / verbosity = excessive flow of speech; in Gajdos it is yoked to flight of ideas as the speech counterpart of accelerated thinking (mania).
