Psychiatry: core clinical skills
Descriptive psychopathology & phenomenology
Descriptive psychopathology is the careful description of abnormal experiences and behaviour, such as delusions, hallucinations and disturbed mood, as the patient experiences them. It is the psychiatrist's core vocabulary and the basis of every diagnosis.
Depth by stage, Pre-U → Consultant (details)
What is it?
In other specialties doctors examine the body; in psychiatry the main 'examination' is of a person's experiences. Descriptive psychopathology gives precise names and definitions for these experiences so that they can be recognised reliably and communicated clearly.
Phenomenology, in the sense used by Karl Jaspers, means trying to understand an experience from the patient's own point of view, without jumping to theories about its cause. For example, a psychiatrist will carefully separate a true hallucination from a vivid image or an illusion.
Training covers abnormalities of perception, thought, belief, mood, self-experience, memory, consciousness, motor behaviour and insight. Getting these distinctions right determines the diagnosis and therefore the treatment.
Why does a psychiatrist need it?
Many important decisions rest on fine distinctions: whether a belief is a delusion or a culturally shared belief, whether a voice is a hallucination or a spiritual experience, whether slowed speech is depression or catatonia. A psychiatrist must make these judgements accurately, document them clearly and explain them in reports and court.

What are the key topics?
Perception
- Illusions, hallucinations and pseudohallucinations
- Modalities: auditory, visual, olfactory, gustatory, tactile, somatic
- Special types: functional and reflex hallucinations, hypnagogic and hypnopompic
- Derealisation and depersonalisation
- Organic clues: visual and olfactory hallucinations
Thought and belief
- Delusions: definition, primary versus secondary, delusional mood and perception
- Delusional themes: persecutory, grandiose, nihilistic, jealousy, erotomanic, religious
- Overvalued ideas and obsessions compared with delusions
- Formal thought disorder: loosening of associations, tangentiality, circumstantiality, neologisms, thought block
- Disorders of thought possession: insertion, withdrawal, broadcast
- Schneider's first-rank symptoms and their limited specificity
Mood, emotion and self
- Mood versus affect; blunted, flat, incongruent and labile affect
- Depressed and elevated mood; anhedonia; alexithymia
- Anxiety and panic phenomena
- Disturbances of self: passivity experiences, depersonalisation
- Body image disturbance
Cognition, consciousness and memory
- Clouding of consciousness and delirium
- Disorientation
- Confabulation and memory falsification
- Attention and concentration disturbances
Motor and behaviour
- Catatonic signs: stupor, mutism, posturing, waxy flexibility, echo phenomena, negativism
- Psychomotor retardation and agitation
- Stereotypies, mannerisms, tics
- Compulsions
Insight and culture
- Insight as a spectrum, not all-or-none
- Distinguishing cultural, religious and spiritual beliefs from delusions
- Culture-bound presentations described in Malaysia (e.g. amok, latah, koro)
- Possession experiences and how to assess them respectfully
How is it learned and assessed?
- Undergraduate psychiatry posting: interviews, case presentations and OSCE stations
- Daily clinical interviews as an MO and trainee, with supervisor feedback
- Examined in MMed Psychiatry (Part I theory and Part II clinical) and in MRCPsych Paper A and the CASC
- Video and case-based teaching sessions on specific phenomena
Typical textbooks and resources
- Sims' Symptoms in the Mind — Femi Oyebode; the standard psychopathology text
- Fish's Clinical Psychopathology — Patricia Casey and Brendan Kelly
- General Psychopathology — Karl Jaspers (in translation)
- Oxford Textbook of Psychiatry — descriptive chapters

Common questions
How does a psychiatrist tell a delusion from a strong religious or cultural belief?
A delusion is a fixed false belief that is out of keeping with the person's cultural and religious background and is held despite clear evidence otherwise. Psychiatrists check whether others in the same community share the belief, and often consult family or religious figures, before calling it a delusion.
Is hearing voices always a sign of mental illness?
No. Brief voices can happen when falling asleep, in grief, under extreme stress or with some medical conditions, and some people hear voices without distress. Psychiatrists look at the full picture before deciding whether it is a symptom of illness.
