Mental Status Exam Notes

General Knowledge and Awareness

  • Assess the patient's general knowledge with simple geographical or current events questions.
  • Determine how the patient identifies and learns best (visual, kinesthetic, etc.).
  • Assess the patient's awareness of current events and basic facts (e.g., knowing who the president is).

Concentration

  • Evaluate concentration using tasks like serial sevens (counting backward by sevens from 100), which is considered difficult.
  • A more common method is asking the patient to spell "world" backwards to assess their thought process.

Abstract Thought

  • Abstract thought assessment is crucial, especially for psychotic disorders.
  • Administer a common proverb and ask the patient to explain its meaning.
  • Example: "Kill two birds with one stone."
    • A normal response would be that you can get two things done at once.
    • A patient with impaired abstract thought might take the proverb literally and not understand its figurative meaning.
  • If English is not the patient's first language, this assessment may not be valid.

Insight and Judgment

  • Insight: Assess the patient's understanding of their illness.
    • Can they acknowledge their diagnosis and its implications (e.g., bipolar disorder and medication adherence)?
    • Or do they deny their illness, possibly attributing symptoms to external factors (e.g., conspiracy theories)?
  • To gauge insight, review the patient's chart and ask directly if they agree with their diagnosis.
    • Example: "I saw in the chart that you've been diagnosed with schizophrenia. Do you agree with that diagnosis?"
    • This approach gives the patient a voice and allows you to understand their perspective.
  • Judgment: Evaluate the patient's decision-making abilities and understanding of consequences.
    • Assess recent choices and circumstances leading to their current situation (e.g., seeking help vs. being brought in by law enforcement).

Rating Scale

  • Use a rating scale (poor, fair, good) to evaluate insight, judgment, and impulse control.

Additional Important Questions (Not in MSE)

  • Anxiety: Inquire about anxiety levels, panic attacks, obsessions, and compulsions, as anxiety is prevalent across many disease states.
    • Assess the severity of anxiety (mild, moderate, severe).
  • Sleep: Always ask about sleep patterns, including the amount and quality of sleep.
    • Determine if they are having difficulty falling or staying asleep.
    • Note if the patient is sleeping excessively (e.g., 17-18 hours a day), which can indicate severe depression.

Formulation of Differential Diagnosis

  • Integrate all information gathered during the mental status exam to formulate a differential diagnosis.
  • Consider the patient's history, symptoms, and observations.
  • Differentiate between drug-induced psychosis and primary psychotic disorders like schizophrenia, which require symptoms to be present for several months outside of drug use or medical conditions.

Interview Techniques

  • Avoid a checklist approach; engage in a natural conversation.
  • Start with open-ended questions to build rapport.
    • Examples: "How's it going?", "Tell me about what brought you here.", "What things have been going well for you since you got here?"
  • Address topics as they arise in conversation, even if they are out of order.
    • If a patient mentions hearing voices, explore that topic even if it was not planned for that point in the interview.
  • Manage tangential responses by redirecting the patient back to the topic at hand.
    • Acknowledge their comments, then refocus with a direct question.
  • When dealing with patients who are incoherent, rely on observations, history, and collateral information.
  • Prioritize what the patient is saying, but also pay close attention to nonverbal cues and behaviors.
    • Example: If a patient denies hearing voices but is seen talking to their wrist, document the observation.

Practical Exercise

  • Engage in role-playing exercises to practice conducting mental status exams.
  • Simulate real-life scenarios with challenging patient behaviors.
  • Provide constructive feedback on interview techniques, focusing on creating a comfortable and non-judgmental environment.
