The mental status exam (MSE) is a structured snapshot of how a client looks, acts, feels, thinks, and perceives during your session. A precise MSE tracks change over time and supports medical necessity, but only if your descriptors match what you observed. This mental status exam cheat sheet gives you terms, definitions, and charting phrases for each domain, with a deep dive on affect and mood.
Key Takeaways
Standard clinical references define mood as the client's self-reported emotional state (ideally quoted) and affect as your observation of their expressed emotion, described by range, intensity, stability, congruence, and appropriateness.
Pair every descriptor with brief behavioral evidence ("flat affect, minimal facial expression, monotone voice") so the note holds up to review and shows change over time.
Building a shared descriptor vocabulary is a practical professional development goal, especially for trainees and supervisors reviewing notes together.
How to Use This MSE Cheat Sheet
This is a terminology reference, not a full write-up. For a complete narrative, see our full mental status exam example, and for phrasing outside the MSE, our mental health clinical language cheat sheet. The domains below follow the order most clinicians chart in, starting with what you see before the client says a word.
Appearance
Appearance covers apparent age, dress, grooming, hygiene, and notable features such as scars. According to the StatPearls review of the mental status examination by Voss and Das (updated 2024), a recent decline in grooming carries more clinical weight than a long-standing pattern, so compare to baseline when you can.
Useful descriptors include "appears stated age," "disheveled," "malodorous," and "wearing a heavy coat in warm weather."
Behavior and Psychomotor Activity
Behavior describes how the client engages: cooperative, guarded, hostile, withdrawn, or redirectable. Note eye contact, and remember that intoxication or medical causes can mimic psychiatric presentations.
Psychomotor retardation means slowed movement and response; psychomotor agitation means excess, often purposeless movement such as pacing. Also chart tremor, posturing (which may suggest catatonia), and medication effects like akathisia or tardive dyskinesia.
Speech
Describe speech by rate, volume, amount, fluency, rhythm, and tone. Reduced or slowed speech can accompany depression, while pressured speech (rapid, hard to interrupt) is commonly seen in mania or intoxication. Slurred speech suggests intoxication, and dysarthria points toward a motor issue.
A sample phrase: "Speech normal rate and volume, spontaneous, fluent, no latency." Once you've charted how the client speaks, you move to how they feel.
Mood Descriptors
Mood is the client's own report of their sustained emotional state. Snyderman and Rovner's 2009 review in American Family Physician defines mood as the patient's internal, subjective emotional state and suggests asking about the past few weeks, not just the moment. Quote the client's words, then add your summary term if helpful.
Term | What it means | Example charting phrase |
|---|---|---|
Euthymic | Normal, stable mood without significant depression or elevation | Mood "pretty good," euthymic |
Depressed / dysphoric | Low, sad, or unpleasant mood | Mood "empty, like nothing matters" |
Anxious | Worried, tense, apprehensive | Mood "on edge all the time" |
Irritable | Easily annoyed or provoked | Mood "everyone is getting on my nerves" |
Euphoric / elevated | Abnormally high or expansive mood | Mood "never better, I'm unstoppable" |
If the client won't or can't describe their mood, chart that ("declined to describe mood") rather than filling in your own inference.
Affect: Types and Descriptors
Affect is what you observe: facial expression, tone, gestures, and how emotion shifts during the session. Snyderman and Rovner organize affect along range, intensity, and stability; most clinicians also chart congruence and appropriateness.
Affect vs Mood
The simplest way to remember affect vs mood: mood is what the client tells you, and affect is what you see. Mood is sustained; affect shifts moment to moment. A client can report a "fine" mood while showing a tearful, constricted affect, and that mismatch is itself a finding.
Range of Affect
Range describes how many emotions the client displays. These types of affect run from most to least expressive.
Term | What it means | Example charting phrase |
|---|---|---|
Full / broad | Normal variety of emotional expression that shifts with content | Affect full range, reactive, smiles appropriately when discussing daughter |
Restricted / constricted | Mildly reduced range; expression stays within a narrow band | Constricted affect, consistently somber, brief smile only once |
Blunted | Marked reduction in intensity of emotional expression | Blunted affect, limited facial expression, voice minimally modulated |
Flat | Absent or nearly absent emotional expression | Flat affect, no change in facial expression or tone across topics |
Clinicians generally treat constricted, blunted, and flat as a continuum of reduced expression (Snyderman and Rovner file blunted and flat under intensity). Flat affect is associated with negative symptoms of schizophrenia but can also reflect severe depression, neurological conditions, or medication effects, so it isn't diagnostic on its own.
Intensity and Stability
Intensity runs from minimal to extreme; heightened intensity might be charted as "intense" or "expansive." Stability describes consistency. A labile affect shifts rapidly and unpredictably, such as laughter to tears without a clear trigger. Chart the shift you saw: "Labile affect, tearful then laughing while discussing the same event."
Congruence and Appropriateness
Term | What it means | Example charting phrase |
|---|---|---|
Congruent | Affect matches the client's stated mood | Mood "awful," affect tearful and constricted, congruent |
Incongruent | Affect conflicts with stated mood | Mood "great," affect tearful, incongruent |
Appropriate | Affect fits the content being discussed | Affect appropriate to content, tearful when describing loss |
Inappropriate | Affect does not fit the content or situation | Smiled and laughed while describing a friend's death |
StatPearls illustrates congruent affect as a client saying "great" while smiling; incongruent is the same word while crying. Next comes how the client thinks.
Thought Process Descriptors
Thought process describes how ideas connect, not what they're about. Snyderman and Rovner frame it as a continuum from goal-directed to disconnected thinking.
Term | What it means | Example charting phrase |
|---|---|---|
Linear | Ideas follow logically from one to the next | Thought process linear and logical |
Goal-directed | Thinking stays oriented toward answering the question | Goal-directed, answers questions directly |
Circumstantial | Excessive detail and detours, but eventually returns to the point | Circumstantial, required redirection but answered questions |
Tangential | Drifts away from the question and does not return | Tangential, did not return to topic of sleep after redirection |
Loose associations (derailment) | Little or no logical connection between successive ideas | Loose associations, shifted between unrelated topics |
Flight of ideas | Rapid succession of ideas with loose, sometimes hard to follow links, often with pressured speech | Flight of ideas, rapid shifts linked by word associations |
Thought blocking | Abrupt stop mid-thought, often unable to resume | Thought blocking noted twice, stopped mid-sentence |
Perseveration | Repeatedly returns to the same word, idea, or topic regardless of the question | Perseverated on landlord dispute across unrelated questions |
Word salad | Severe incoherence where words are strung together without meaningful grammar | Speech incoherent, word salad, unable to assess content |
Clang associations | Words chosen by sound, such as rhyme or puns, rather than meaning | Clang associations, "the cat, the hat, the bat" |
The Johns Hopkins Psychiatry Guide entry on thought disorder defines clanging and word salad consistently with the table above.
Thought Content
Thought content is what the client is thinking about. Always document suicidal and homicidal ideation explicitly, including pertinent negatives. StatPearls notes the importance of distinguishing passive ideation (wishing to be dead) from active ideation, and active ideation calls for assessing plan, intent, and access to means. A sample phrase: "Endorses passive SI, denies plan or intent; denies HI."
Delusions are fixed false beliefs that persist despite contrary evidence and aren't explained by the client's cultural or religious background. Common types include persecutory (paranoid), grandiose, somatic, and referential (ideas of reference), as well as thought insertion, withdrawal, and broadcasting. Chart the belief in the client's words when possible.
Obsessions are intrusive, unwanted thoughts, urges, or images the client recognizes as their own; also note preoccupations and ruminations. If thought content involves risk to others, review what therapists are required to report in your jurisdiction.
Perception
Perception covers hallucinations (perception without an external stimulus) and illusions (misperception of a real stimulus). Specify the modality: auditory, visual, tactile, olfactory, or gustatory. For auditory hallucinations, document whether voices are commands and what they say.
Chart observed behavior too. A client may deny hallucinations while appearing to respond to internal stimuli, such as pausing to listen or glancing at an empty corner. If psychotic symptoms emerge, consider when to refer clients to psychiatry.
Cognition and Sensorium
Cognition covers level of consciousness (alert, somnolent, obtunded, stuporous, comatose), orientation to person, place, and time, attention and concentration, memory, and abstract reasoning. Serial 7s or spelling a word backward test attention; a literal proverb interpretation suggests concrete thinking.
When you suspect a neurocognitive disorder, a structured screener such as the Mini-Mental State Examination (MMSE), the Montreal Cognitive Assessment (MoCA), or the Mini-Cog adds objective data. Abnormal findings may warrant a referral for a neuropsychological evaluation.
Insight and Judgment
Insight is the client's understanding of their condition. Judgment is their capacity to make sound decisions, usually inferred from recent behavior. Both are commonly rated as good, fair, limited, or poor.
Back up the rating with evidence: "Insight fair, acknowledges depression but attributes it entirely to job stress; judgment fair, missed two medication doses this week." Now that each domain is covered, here's how they come together.
Sample MSE Paragraph
The following is a fictional, de-identified example for a 34-year-old client at a follow-up visit:
"Client appears stated age, casually dressed, mildly disheveled. Cooperative, fair eye contact, psychomotor retardation noted. Speech soft, slowed, with increased latency. Mood 'heavy, like I'm underwater.' Affect constricted and tearful, congruent with mood, appropriate to content. Thought process linear and goal-directed. Endorses passive SI ('sometimes I wish I wouldn't wake up'), denies plan, intent, or HI. No delusions elicited. Denies AH/VH; not responding to internal stimuli. Alert and oriented x3; attention intact to serial 7s. Insight fair; judgment fair."
Common MSE Charting Pitfalls
Vague terms are the most frequent MSE documentation problem. Watch for:
Writing "appropriate" alone without saying appropriate to what (content, setting, or mood).
Charting a descriptor such as "flat affect" without behavioral evidence like facial expression or vocal tone.
Paraphrasing mood instead of quoting the client.
Omitting pertinent negatives, especially SI, HI, and hallucinations.
Copying forward the last MSE unchanged instead of documenting what you observed today.
Documenting the MSE Efficiently
The MSE usually lives inside a larger note, such as a psychiatric intake note, a psychosocial assessment, or the objective section of a SOAP note for depression. Keeping descriptors consistent from session to session makes it easier to show change and support medical necessity.
Berries generates intake and progress notes, including MSE content, from a live session capture or dictation, using its 20+ built-in templates or your own sections created with the template builder. Because the MSE is observational, you'll still review and edit every descriptor so it reflects what you saw. You can try Berries free for your first 20 sessions, no credit card required.
Frequently Asked Questions
What is the difference between flat affect and blunted affect?
Blunted affect is a marked reduction in emotional expression; flat affect is its near absence. Constricted affect is a milder reduction. Describe the features that led you to the term.
What does congruent affect mean?
Congruent affect means what you observe matches the client's reported mood, such as tearfulness when they say they feel sad. Incongruent affect is a mismatch.
Do I need to complete a full MSE at every session?
Many clinicians complete a full MSE at intake and a focused MSE at follow-ups, emphasizing risk and the presenting problem. Check payer and agency requirements, since expectations vary.
Can I use the MMSE or MoCA in a therapy practice?
Both are copyrighted instruments with their own licensing, and the MoCA has training requirements. Confirm you have appropriate access before administering either.
