There are three important disorders of the form of thought:

  • preoccupations:
    • these are thoughts or patterns of thinking which occur frequently but can be terminated if desired
    • one should always enquire about suicidal preoccupations in the depressed patient
    • preoccupations are a perpetuating factor in anxiety disorders e.g. thoughts about health in panic disorder

  • obsessive thoughts:
    • these are intrusive thoughts which are resisted by the patient
    • often the content of the thought is thought unacceptable

  • delusions:
    • in brief, a delusion is a false belief which is both culturally unconventional and held on inadequate grounds
    • delusions may be difficult to elicit as the patient either does not view them as unusual or is suspicious of the interviewer
