PS1.1-3 | Introduction to Psychiatry — Practice Quiz

Correct. The hallmarks of neurotic disorders are preserved insight (the patient recognises the symptoms as abnormal) and intact reality testing (no delusions or hallucinations). Autonomic symptoms like palpitations are common in anxiety disorders, which are neurotic in nature.

Neurotic disorders are characterised by preserved insight, intact reality testing, and absence of delusions or hallucinations. The inability to control symptoms does not make a disorder psychotic.

Review the neurotic-psychotic dichotomy. The key distinguishing feature of neurosis is preserved insight and intact reality testing — the patient knows something is wrong and can distinguish her experience from external reality. This case lacks any psychotic features.

Correct. An acute confusional state with visual hallucinations and disorientation in the context of severe hypertension (possible hypertensive encephalopathy) has a clear organic aetiology. Organic psychiatric disorders arise from identifiable physical causes affecting brain function.

Any acute psychiatric presentation with confusion, disorientation, or visual hallucinations in an older patient must first be evaluated for organic causes (MIDAS: Metabolic, Infective, Drugs/toxins, Anatomic/structural, Systemic). Hypertensive encephalopathy is a medical emergency.

Examine the history carefully. The acute onset, the physical cause (severe hypertension), and the presence of confusion and disorientation all point to an organic aetiology — a physical disorder causing psychiatric symptoms. Always exclude organic causes before diagnosing a functional psychiatric disorder.

Correct. ICD-11 Chapter 6 covers Mental, behavioural or neurodevelopmental disorders. This chapter replaced the ICD-10 Chapter 5 (F-codes) and reflects a more neuroscientifically informed classification.

ICD-11 Chapter 6 is the current international classification for psychiatric disorders (superseding ICD-10 Chapter 5/F-codes). DSM-5 is the parallel American classification used extensively in research.

ICD-11 places mental disorders in Chapter 6 (Mental, behavioural or neurodevelopmental disorders). This is an important reference point because prescriptions, medicolegal documentation, and insurance coding all use ICD codes.

Correct. Sitting quietly and acknowledging distress is the therapeutic response — it validates the patient's experience, preserves the therapeutic alliance, and allows history-taking to resume when she is ready. This is a core principle of the psychiatric interview.

The psychiatric interview requires empathic attunement. When a patient becomes distressed, the clinician should pause, acknowledge the patient's feelings ('I can see this is difficult for you'), and allow resumption at the patient's pace rather than pressing on or deflecting.

Moving on abruptly or substituting a family member without the patient's consent disrupts the therapeutic relationship and may miss critical information. False reassurance ('everything will be fine') is inappropriate in any clinical interview. The correct response honours the patient's distress without abandoning the interview.

Correct. Renal function and creatinine clearance are not standard components of the psychiatric history. They may be relevant before prescribing lithium or clozapine but are part of the physical examination and investigations, not the history-taking domain.

The structured psychiatric history covers: presenting complaint, history of presenting illness, past psychiatric and medical history, family history, personal and developmental history, premorbid personality, social history, and substance use. Investigations (including blood tests) are a separate step.

All standard psychiatric history domains — family history, premorbid personality, and substance use — are required in a first psychiatric assessment. Renal function is a laboratory investigation, not a component of history-taking, though it becomes relevant to prescribing.

Correct. Flight of ideas is characterised by a rapid succession of thoughts with some (often loose) associative links, resulting in inability to complete any single thought. It is a classic feature of mania. The links between topics may be based on clang associations, rhymes, or superficial connections.

Flight of ideas = rapid topic-switching with loosely discernible links, thoughts not completed — seen in mania. Distinguish from tangentiality (drifting from the topic), perseveration (repetition), and thought blocking (sudden cessation).

Review MSE thought process abnormalities. Flight of ideas is the rapid flow of loosely linked thoughts with topic-switching before ideas are completed — classic in mania. Tangentiality answers a question by progressively drifting away; perseveration is pathological repetition; thought blocking is a sudden pause and emptying of the mind.

Correct. The MSE is a structured, clinician-administered assessment of the patient's current mental functioning — analogous to the physical examination in general medicine. It documents what the clinician observes and elicits at the time of the interview, not the patient's historical background.

The MSE assesses current mental state across eight domains: Appearance, Behaviour, Speech, Mood and Affect, Thought (form and content), Perceptions, Cognition, and Insight/Judgement. It is performed by the clinician, not self-reported.

The MSE is a cross-sectional, clinician-administered assessment of current mental state — distinct from the psychiatric history (which is longitudinal) and from neuropsychological batteries (which are specialised formal tests). It covers eight domains observed and elicited in the interview.

Correct. Both statements relate to mood. The patient's own description ('black cloud') is her subjective mood — what she reports experiencing. The numerical self-rating (2/10) is an operationalised, objective measure of the same subjective experience. Affect, by contrast, is the clinician's observation of emotional expression (facial expression, voice tone, gestures).

Mood = sustained subjective emotional state reported by the patient. Affect = the clinician's objective observation of moment-to-moment emotional expression (range, reactivity, congruence). Distinguish these clearly in MSE documentation.

In MSE, mood is the patient's sustained subjective emotional state (what the patient describes experiencing), while affect is the clinician's observation of the patient's emotional expression moment to moment. Both the descriptive statement and the numerical rating here relate to mood.

Correct. The Mental Healthcare Act 2017 enshrines the right of persons with mental illness to make decisions about their own treatment. This patient has capacity (insight preserved, no risk of harm to self/others). Involuntary admission requires specific criteria (imminent risk of serious harm, or inability to make treatment decisions) that are NOT met here.

Mental Healthcare Act 2017: (1) Every person has the right to make treatment decisions. (2) Involuntary admission requires imminent risk of serious harm + inability to make treatment decisions. (3) OCD with insight does not meet involuntary criteria. This is a key medicolegal principle in psychiatry.

The Mental Healthcare Act 2017 affirms patient autonomy and the right to treatment decisions. Involuntary admission is not appropriate simply because someone has a mental illness — it requires imminent risk of harm to self or others AND inability to make treatment decisions. This patient has full insight and capacity.
