Psychopathology and Psychiatric Assessment
This domain tests whether you can describe abnormal mental events precisely, recognise syndromes from those descriptions, and defend a formulation. Egyptian board examiners reward correct phenomenological terminology and an explicit risk formulation; vague labels such as psychotic or confused without descriptive support lose marks.
Structure of the assessment
A defensible assessment moves from history (presenting complaint, chronology, premorbid personality, family history, substance use, medical history, collateral from a relative) to the mental state examination in a fixed order: appearance and behaviour, speech, mood and affect, thought form and content, perception, cognition, insight and judgement, then risk. Always record what the patient actually said and did before interpreting it.
Precision terms you must distinguish
- Illusion: distorted perception of a real external stimulus. Hallucination: perception without an object, in external space. Pseudohallucination: located in inner subjective space, recognised as not real.
- Delusion: fixed, falsely held belief, out of keeping with the person's culture, held with extraordinary conviction despite evidence. Types include persecutory, grandiose, nihilistic, erotomanic, and the passivity phenomena (thought insertion, withdrawal, broadcasting, made actions, made affects, made impulses).
- Formal thought disorder: derailment, loosening of associations, flight of ideas, thought blocking, neologisms, clang associations, circumstantiality, tangentiality.
- Schneiderian first-rank symptoms: audible thoughts, voices arguing or discussing the patient in the third person, voices commenting on actions, thought echo, thought broadcast, made phenomena, delusional perception. They support but do not diagnose schizophrenia.
- Insight is graded, from complete denial through partial awareness to full acceptance, and should be recorded dimensionally, not as present or absent.
Worked example
A 26-year-old man says the radio transmits his thoughts so neighbours hear them, and that his limbs are moved by an external force. Reasoning: thought broadcasting and made actions are both passivity phenomena, so the description supports a psychotic syndrome with first-rank features. Because the same phenomena occur in bipolar disorder and in organic states, the next steps are a mood chronology, cognitive screening, urine toxicology, thyroid function, and a risk assessment including command hallucinations and self-neglect. Committing to schizophrenia at this point would be premature, since duration and functional decline are not yet established.
Traps that cost marks
Calling a culturally sanctioned belief (for example, possession or the evil eye) a delusion without establishing that it is outside the person's cultural group. Confusing blunted affect with depressed mood. Failing to examine cognition in a first episode after age 40. Describing speech as disorganised without quoting an example. Using rating scales such as the PANSS, HAM-D, YMRS or MMSE as diagnostic instruments rather than as measures of severity or change.
