Mental Status Exam Example for Depression | MSE Guide

Across the UK, GPs, mental health nurses, and private practitioners face a shared documentation challenge: how to write a structured, defensible mental state examination for a patient with depression when most available guidance is aimed at medical students preparing for OSCEs. Resources from Geeky Medics and Zero To Finals are thorough for exam purposes, but they do not reflect the realities of a busy NHS surgery or a CQC-regulated private clinic, where time is short and clinical records carry significant medicolegal weight.

This article provides a domain-by-domain breakdown of expected MSE findings in depression, a fully written narrative MSE example you can reference and adapt, and practical guidance for non-specialist clinicians conducting a psychiatric assessment in primary care or independent practice. If you are looking for a mental health assessment questionnaire framework to sit alongside your MSE, that resource is also available on this site.

Whether you are completing your first formal mental status exam in a community setting or refining your documentation for a CQC inspection, this guide gives you the clinical language, the written example, and the workflow context you need.

What Is a Mental State Examination (MSE)?

A mental state examination is a structured, clinician-led, cross-sectional observation of a patient's mental functioning at a specific point in time. It is objective and observational in nature, recording what the clinician sees and hears during the consultation rather than what the patient reports about their history.

This is an important distinction. The psychiatric history is largely a subjective assessment, drawing on the patient's own account of symptoms, past episodes, and life circumstances. The MSE, by contrast, is an objective assessment: the clinician systematically observes and documents the patient's presentation across standardised domains. Both are necessary, but they serve different purposes and should be recorded separately.

It is equally relevant for GPs conducting a structured assessment in primary care as it is for consultant psychiatrists. The ten standard domains of the MSE are: appearance, behaviour, speech, mood and affect, thought process, thought content, perception, cognition, insight, and judgement and risk. For nurses seeking additional structured assessment tools, our overview of mental health assessment tools for nurses covers validated instruments that complement the MSE.

MSE Components: A Quick Reference for Depression

The table below provides an at-a-glance reference for all ten MSE domains. For patients presenting with depression, the domains most diagnostically significant are mood and affect, thought content, speech, behaviour, and risk assessment.

A useful memory aid taught in UK medical training is the ASEPTIC mnemonic, which stands for Appearance, Speech, Emotion (encompassing mood and affect), Perception, Thought, Insight, and Cognition. It covers the same domains in a slightly condensed format and is a practical recall tool under time pressure, though risk and judgement should always be documented explicitly alongside it.

What Does Depression Look Like on an MSE? Domain-by-Domain Guide

Understanding how each domain presents in moderate-to-severe depression is essential for writing an accurate and defensible record. The following describes characteristic clinical findings, with notes on differential diagnosis where relevant.

• Appearance and behaviour. Patients with depression often present with a stooped posture and downcast gaze. Dress may be unkempt, and signs of self-neglect are common in moderate-to-severe cases, including poor personal hygiene, unwashed hair, or clothing that appears worn repeatedly. Weight loss may be visible. Reduced eye contact is typical. Psychomotor retardation is a hallmark feature, manifesting as noticeably slowed movements, reduced spontaneous gesturing, and a general reduction in physical activity.

In some patients, particularly those with agitated depression or mixed presentations, psychomotor agitation may be observed instead, presenting as restlessness, hand-wringing, or inability to sit still.

• Speech. Speech in depression is characteristically reduced in rate, volume, and spontaneity. Paucity of speech is common, with long pauses before responses. Alogia, or poverty of thought content expressed through speech, may be present in more severe cases. The tone is often monotone with little variation in pitch or prosody.
• Mood and affect. The patient typically reports low mood or describes their mood as depressed, empty, or hopeless. The clinician observes affect as blunted affect or constricted affect, with a narrowed range of emotional expression. In severe cases, flat affect may be present, with an almost complete absence of expressivity. Affect is usually mood congruent in uncomplicated depression. Mood incongruent affect, where observed emotion contradicts reported mood, should prompt consideration of psychotic features or a bipolar presentation.
• Thought process. Thinking in depression is typically slow, with poverty of thought and reduced ideational flow. Thought blocking, where the patient appears to lose their train of thought mid-sentence, may occur. Rumination is a common feature, with the patient returning repeatedly to themes of failure, loss, or regret.
• Thought content. This is often the most diagnostically informative domain in depression. Characteristic themes include hopelessness about the future, worthlessness, and pervasive guilt, often disproportionate to any actual events. Nihilistic thinking may be present in severe cases. Suicidal ideation requires explicit assessment and documentation, which is addressed in detail in a dedicated section below.

For a broader look at structuring clinical documentation around these findings, our guide to mental health SOAP notes is a useful companion resource.

• Perception. In uncomplicated depression, hallucinations are not expected. There are typically no auditory hallucinations, visual hallucinations, or other perceptual disturbances. However, in psychotic depression, auditory hallucinations (typically mood congruent, such as voices confirming worthlessness) and delusions (often nihilistic or guilt-laden) may be present. Their absence should be explicitly documented.
• Cognition. Cognitive impairment in depression is well recognised. Patients commonly report subjective memory complaints and difficulty concentrating, and this is usually observable in the consultation through slowed processing, difficulty following questions, and poor recall. Orientation to time and place is typically preserved. When significant cognitive impairment is suspected, formal tools such as the MMSE or MoCA can supplement observational findings.
• Insight. Insight is variable in depression but is often partially or fully preserved. Most patients are aware they are unwell. In severe or psychotic depression, insight may be impaired.
• Judgement and risk. Judgement may be impaired in severe depression, particularly regarding self-care decisions or treatment engagement. Risk assessment, including suicidal ideation and self-harm, must always be documented explicitly.

By contrast, patients with bipolar disorder in a manic phase would present with elevated or labile affect, pressured speech, and grandiose thought content, making the MSE profile quite distinct from the depressed presentation described here. In anxiety disorders, thought content tends to centre on threat and worry rather than hopelessness and worthlessness, and psychomotor retardation is less prominent.

Understanding the Difference between Mood and Affect in Depression

Mood and affect are frequently conflated in clinical notes, but they describe distinct phenomena and should be documented separately in any MSE.

• Mood refers to the patient's subjective, sustained internal emotional state: what they report feeling over time. In depression, patients typically describe their mood as persistently low, dysphoric, empty, or despairing. This is obtained through direct questioning and recorded as the patient's own account.
• Affect refers to the clinician's objective observation of the patient's expressed emotion during the consultation. The clinician observes what is visible, not what is reported. Affect can be described using the following spectrum: normal range; constricted affect, which is a mildly reduced range of expression; blunted affect, a more marked reduction where the patient shows little emotional reactivity; and flat affect, an almost complete absence of expressivity. Lability, characterised by rapid and unpredictable shifts in emotional expression, may also be noted when present.

Mood congruent affect means the observed emotional expression is consistent with the reported mood, which is typical in depression. Incongruent affect, where the patient reports low mood but appears animated or laughing without context, should raise a flag for possible psychotic features, bipolar disorder, or a dissociative presentation, and warrants explicit comment in the record.

Written MSE Example for a Patient with Depression

The following is a sample MSE report for educational purposes. It does not represent a real patient and should be adapted to reflect the clinician's actual observations in any live consultation.

Several documentation choices in this mental status exam example are worth noting. The phrase "blunted and constricted, mood congruent" is more clinically precise than recording simply "she seemed sad," as it specifies both the quality and congruence of affect. Psychomotor retardation is recorded behaviourally, as an objective observation, not as a diagnosis. Suicidal ideation is documented with specific detail about passive versus active ideation and the absence of intent or plan.

This MSE template reflects how a clinician would write in a real medical record, not a checklist format. For additional guidance on how to write therapy notes in connected prose, see our article on how to write therapy notes.

Documenting Suicidal Ideation and Risk in a Depressive MSE

Suicidal ideation documentation is one of the most clinically and legally significant parts of any depressive MSE. Brief or vague entries such as "no SI" are inadequate from both a clinical and medicolegal documentation standpoint.

A defensible record should reflect:

• Whether passive suicidal ideation was present (for example, a wish to be dead, or a sense that others would be better off without the patient)
• Whether active suicidal ideation was present, meaning purposeful thoughts of ending one's life
• The presence or absence of intent to act
• The presence or absence of a specific plan
• Access to means relevant to any plan
• Protective factors, such as family, religious beliefs, or engagement with services
• Any recent acts of self-harm, including method, frequency, and intent

Where clinically significant, the patient's own words should be included in the record, clearly attributed. For example: "Patient stated 'sometimes I think it would be easier if I just wasn't here' but denied any intent or plan to act on these thoughts."

In NHS settings and CQC-regulated private practice, the expectation is that risk documentation is specific, proportionate, and defensible. A CQC inspection may review mental health records to assess whether clinicians have identified and recorded risk factors appropriately. A record that simply states "low risk" without the underlying clinical reasoning does not meet that standard.

Risk documentation in the MSE also connects directly to safety planning. If suicidal ideation is present, the record should note whether a safety plan was discussed, what it included, and whether onward referral or emergency action was taken.

MSE in Depression: Practical Tips for GPs and Non-Specialist Clinicians

Conducting a full formal MSE in a ten-minute NHS primary care appointment is not always realistic. However, the key domains of any psychiatric assessment, particularly appearance and behaviour, mood and affect, thought content, and risk assessment, should always be documented, even in a brief consultation.

The following practical tips are aimed specifically at GPs, practice nurses, and non-specialist clinicians working in primary care or community settings.

1. Use a brief structured template to prompt recall under time pressure. A pre-built MSE template within your consultation notes reduces the cognitive load of remembering every domain and ensures nothing is omitted. Our overview of mental health assessment tools for nurses covers a range of tools that can complement structured documentation.
2. Record mood and affect separately. The patient's reported mood should be documented in their own words where possible. The clinician's objective observation of affect should be recorded as a separate finding, using precise terminology such as blunted, constricted, flat, or labile.
3. Always document suicidal ideation explicitly. Never leave it implied or assumed. A record with no mention of risk assessment for a depressed patient is a significant clinical and documentation gap.
4. Use validated tools alongside the MSE. The PHQ-9 adds quantitative, reproducible data to the qualitative findings of the MSE and supports tracking of treatment response over time. It does not replace the MSE but complements it. In patients where cognitive impairment is a feature, formal instruments such as the MMSE or MoCA can supplement observational findings from the cognition domain.

5. Document cognitive observations to guide referral decisions. If you observe slowed processing, poor recall, or difficulty following instructions during the consultation, record it. This supports onward referral to secondary care or memory services, and provides a baseline for tracking whether cognition improves with diagnosis and management of the depressive episode.

How to Record an MSE in Your Practice Management System

Writing a complete, defensible MSE under genuine time pressure is considerably more manageable when you have a structured digital template built into your workflow. Relying on free-text notes alone increases the risk of omitting domains, introduces inconsistency across clinicians, and makes audit review more time-consuming.

Medesk's customisable consultation note templates allow clinicians to build a structured MSE template with each domain as a discrete, labelled field. This means that when a clinician opens a mental health consultation note, the ten MSE domains appear as a structured framework, ensuring no domain is missed and no prompting from memory is required.

If you are considering moving away from paper-based records, our article on why switch from paper to electronic health records sets out the practical case.

Medesk's patient records and clinical notes feature stores every MSE entry securely within the patient timeline. This supports longitudinal review and means that a clinician conducting a follow-up assessment three months later can review the baseline MSE directly within the same record, tracking changes in thought content, affect, cognition, and risk over the course of treatment. This is particularly relevant for monitoring treatment response in depression, where serial assessments are a key part of clinical management.

The platform's telemedicine video capability means that MSEs can be conducted and documented in a remote consultation, which is increasingly relevant for private mental health providers offering online services. The MSE notes from a remote appointment are stored in exactly the same way as those from an in-person visit. Automated reminders ensure follow-up MSE appointments are not missed, supporting continuity of serial assessment.

Frequently Asked Questions About the MSE in Depression

1. What is a mental state examination, and what does it assess?

A mental state examination is a structured, clinician-led, cross-sectional observation of a patient's mental functioning at a specific point in time. It assesses ten domains: appearance, behaviour, speech, mood and affect, thought process, thought content, perception, cognition, insight, and judgement and risk. Unlike the psychiatric history, which is retrospective and largely subjective, the MSE is an objective assessment based on direct clinical observation.

2. What does a depressed mental status look like?

In depression, key MSE findings include stooped posture, downcast gaze, self-neglect, psychomotor retardation or psychomotor agitation, paucity of speech with a monotone speech quality, depressed mood, blunted or flat affect, and thought content dominated by hopelessness, worthlessness, and guilt. Suicidal ideation should always be assessed. Cognitive impairment affecting concentration is also commonly observed.

3. What is the difference between blunted, constricted and flat affect?

These terms describe points on a spectrum of reduced emotional expressivity. Constricted affect represents a mildly reduced range of emotional expression. Blunted affect is a more marked reduction, where the patient shows little emotional reactivity. Flat affect refers to an almost complete absence of expressivity. All three may appear in depression, with severity broadly corresponding to the degree of reduction.

4. What is the ASEPTIC mnemonic for the MSE?

ASEPTIC is a UK training mnemonic used by medical students and trainees as a memory aid for the MSE domains. It stands for Appearance, Speech, Emotion (covering mood and affect), Perception, Thought, Insight, and Cognition. It is a practical recall tool, though risk and judgement should always be documented explicitly alongside the domains it covers.

5. What does insight look like in a depressed patient?

Insight is often partially or fully preserved in depression. Most patients acknowledge they are unwell and understand that their experiences reflect illness rather than a straightforward personal failing. However, in severe or psychotic depression, insight may be significantly impaired. Documentation should specify what the patient believes about their condition, its cause, and whether they accept the need for treatment.

6. Can a patient with depression deny low mood, and how should this be documented?

Yes. Some patients with depression present primarily with somatic symptoms, anhedonia, fatigue, or irritability rather than an explicit complaint of depressed mood. When this occurs, the discrepancy should be documented explicitly: the patient's self-reported mood is recorded in their own words, and the clinician's objective observation of affect is recorded separately. If incongruence is present, it should be noted and the clinical reasoning explained.

7. What cognitive findings are typical in depression during an MSE?

Common findings include subjective memory complaints, impaired concentration, slowed processing speed, and difficulty with complex tasks. These are often observable during the consultation. When significant cognitive impairment is present, or when pseudodementia is being considered, formal testing using the MMSE or MoCA can supplement the clinical observation and provide a documented baseline.

8. What is the relationship between chronic physical illness and depression in a psychiatric assessment?

Chronic physical illness, including cardiovascular disease, diabetes, and chronic pain conditions, is a recognised risk factor for depression. In the MSE and wider psychiatric assessment, clinicians should document relevant medical history. Some somatic MSE findings, such as fatigue or psychomotor slowing, may reflect physical as well as psychiatric illness, and this should be acknowledged in the clinical formulation.
