Mental Status Examination

On this page

MSE Intro - Look & Act

  • General Appearance:
    • Hygiene & grooming (e.g., kempt, dishevelled, unkempt).
    • Attire (e.g., appropriate, inappropriate, bizarre).
    • Apparent age vs. stated age; distinguishing features.
    • Build, nutritional status, level of consciousness.
  • Attitude Towards Examiner:
    • Cooperative, friendly, attentive, interested.
    • Hostile, guarded, suspicious, evasive, seductive.
    • Apathetic, indifferent, perplexed, distractible.
  • Behavior & Psychomotor Activity:
    • Eye Contact: Good, poor, staring, avoidant.
    • Level: Normal, increased (e.g., restlessness, agitation, hyperactivity), decreased (e.g., psychomotor retardation, stupor).
    • Abnormal movements: Tics, tremors, stereotypies (repetitive, non-goal-directed), mannerisms (goal-directed, idiosyncratic), posturing.

    ⭐ Echopraxia, the pathological imitation of an examiner's movements, can be seen in catatonia or schizophrenia.

  • Rapport: Quality of interaction (e.g., easily established, tenuous, poor).

Speech & Feels - Talk the Mood

  • Speech:
    • Rate: ↑ (mania, anxiety), ↓ (depression), pressured (mania - requires nuanced assessment per DSM-5-TR criteria).
    • Volume: ↑ (mania), ↓ (depression), monotonous (depression, schizophrenia spectrum disorders).
    • Quantity: Paucity/Alogia (depression, schizophrenia spectrum per current diagnostic criteria), Logorrhea/Voluble (mania).
    • Tone: Reflects mood; e.g., hopeless in depression.
    • Articulation: Dysarthria, stuttering.
  • Mood (Sustained, Subjective): Patient's self-reported emotional state.
    • Types: Euthymic (normal), Persistent Depressive (formerly dysthymic), Euphoric (high), Anxious, Irritable.
    • Alexithymia: Difficulty identifying/describing own emotions.
  • Affect (Observed, Objective): Examiner's observation of patient's emotional expression.
    • Range: Full, Restricted, Blunted, Flat (severe reduction).
    • Congruence: Appropriate/Inappropriate to thought content/situation.
    • Stability: Stable vs. Labile (rapid, exaggerated shifts).

⭐ Flat affect (diminished emotional expression) is a key negative symptom in Schizophrenia spectrum disorders per DSM-5-TR classification.

Thought Streams - Sense & Psyche

Thought Process (Form)

  • Normal: Logical, goal-directed.
  • Abnormalities:
    • Flight of Ideas: Rapid, linked topic shifts (Mania).
    • Loosening of Associations (Derailment): Illogical connections (Schizophrenia).
    • Tangentiality: Never returns to point.
    • Circumstantiality: Excessive detail, returns to point.
    • Thought Blocking: Sudden stop (Schizophrenia).
    • Perseveration: Repetition of response.
    • Neologisms: New words.
    • Clang Associations: Sound-based links.

Thought Content

  • Delusions: Fixed, false beliefs (culturally incongruent).
    • Types: Persecutory, grandiose, referential, control (insertion, withdrawal, broadcast), nihilistic.

    ⭐ Schneider's First Rank Symptoms (FRS) include specific delusions of control (thought insertion/withdrawal/broadcast) & certain auditory hallucinations. While historically considered highly suggestive of schizophrenia, modern DSM-5-TR emphasizes broader symptom assessment and dimensional approach rather than relying on FRS specificity.

  • Obsessions: Intrusive, recurrent thoughts/urges.
  • Suicidal/Homicidal Ideation: Assess risk.

Perception

  • Hallucinations: False perception without stimuli.
    • Auditory (Schizophrenia).
    • Visual (Organic states, delirium).
    • Tactile (e.g., formication - substance withdrawal).
    • Olfactory/Gustatory (Temporal Lobe Epilepsy).
  • Illusions: Misinterpretation of real stimuli.
  • Depersonalization/Derealization: Detached from self/surroundings.

CogniCheck - Know & Judge

  • Cognition (Higher Mental Functions):
    • Consciousness: Level of awareness (alert, drowsy, stupor, coma). GCS primarily used for acute brain injury assessment, not standard MSE.
    • Orientation: Time, Place, Person (📌 TPP). Disorientation suggests organic issues.
    • Attention & Concentration: Focus; serial 7s/3s, spelling backward, digit span tests.
    • Memory:
      • Immediate: Registration (3 words).
      • Recent: Recall (3-5 min).
      • Remote: Past events.
    • Intelligence & Abstraction: Knowledge, vocabulary, proverbs, similarities.
  • Insight (Understanding of Illness):
    • Traditional grading: 1 (denial) to 6 (true emotional insight & change). Modern assessment emphasizes qualitative description considering multiple dimensions.
    • Awareness of mental disorder and its implications.
  • Judgment (Decision-Making):
    • Test: Hypothetical social situations (e.g., "fire in theatre").
    • Social: Appropriateness of social behavior.
    • Personal: Realistic future plans.

⭐ Lack of insight (anosognosia) is a core feature in severe mental illnesses like schizophrenia and is a poor prognostic indicator.

High‑Yield Points - ⚡ Biggest Takeaways

  • MSE: Current mental state snapshot; vital for BNS Sec 19 (insanity) & fitness to plead.
  • Key: Appearance, Behavior, Speech (ABS); Mood (subjective) vs. Affect (objective).
  • Thought: Assess Process (flight of ideas) & Content (delusions, suicidal ideation).
  • Perception: Note Hallucinations (auditory in schizophrenia, visual in organic) & Illusions.
  • Cognition: Check Orientation (TPP), Memory, Attention. MMSE is a tool.
  • Insight & Judgment: Crucial for criminal responsibility & testamentary capacity.
