A mental state examination is a structured way of assessing a patient's current state of mind
Appearance and behaviour
Speech
Mood and affect
Thoughts
Perception
Insight and judgement
Risk
Appearance:
Personal hygiene: are there any signs of self-neglect?
Clothing: are they dressed appropriately for the weather/circumstances? Are clothes put on correctly?
Physical signs of underlying difficulties: any self-harm scars or signs of intravenous drug use?
Stigmata of disease: note any stigmata of disease (e.g. jaundice).
Weight: note if they appear significantly underweight or overweight.
Objects: look around to see if the patient has brought any objects with them and note what they are.
Behaviour is split into:
Engagement and rapport
Eye contact
Facial expression
Body language
Psychomotor activity
Abnormal movements or postures
Behaviour - engagement and rapport:
Note if the patient appears engaged in the consultation and if you can develop a rapport with them.
Note if they appear distracted or appear to be responding to hallucinations (e.g. replying to auditory hallucinations in schizophrenia).
Behaviour - eye contact:
Observe level of eye contact
Reduced
Intense and staring
Behaviour - facial expression:
Observe - e.g. relaxed, fearful, disengaged
Note if responding appropriately e.g. becoming tearful when discussing difficult topics vs laughing incongruously
Behaviour - body language:
May appear threatening or withdrawn
Note any evidence of exaggerated gestures or unusual mannerisms
Observe for signs of paranoia e.g. appears on edge, glancing around the room
Behaviour - psychomotor activity:
Psychomotor retardation - lack of/slowing down of movements, delayed responses to questions
Restlessness - patient may continuously fidget, pace and refuse to sit still
Behaviour - abnormal movements or postures:
Involuntary movements
Tremors
Tics
Lip-smacking
Akathisias - unable to sit still
Rocking
Posturing - rigid body movements or chronic abnormal positions
Speech is split into:
Rate
Quantity
Tone
Volume
Fluency and rhythm
Speech - rate:
Pressure of speech - tendency to speak rapidly, motivated by an urgency that may not be apparent to the listener - can be present in mania
Slow - may occur due to psychomotor retardation - typically associated with depression
Speech - quantity:
Poverty of speech (alogia) - depression
Excessive - mania
Speech - tone:
Monotonous - associated with depression, psychosis and autism
Tremulous - associated with anxiety
Speech - volume:
Quiet speech may be seen in depression
Loud speech may be seen in mania
Speech - fluency and rhythm of speech:
Stammering or stuttering
Slurred - may occur in major depression due to psychomotor retardation. also sign of acute intoxication
Stilted speech - unnatural and formal - can be due to thought block
Mood vs affect:
Both relate to emotional but are fundamentally different
Mood represents a patients predominantsubjective internal state at any of time as described by them
Affect represents an immediately expressed and observed emotion e.g. patients facial expression
Mood:
Can be explored with questions such as: "how are you feeling?" and "what is your current mood?"
Examples of mood states:
Low mood
Anxious
Angry
Enraged
Euphoric
Guilty
Apathetic - no interest or enthusiasm
Affect:
Apparent emotion e.g. sadness, anger
Range and mobility of affect e.g. fixed affect (remains the same), restricted (doesn't demonstrate normal range expected), labile (exaggerated changes in emotion)
Intensity - E.g. heightened (mania), blunted or flat (schizophrenia, depression)
Congruency - if the patients affect appears in keeping with the content of their thought. Incongruent affect is typically associated with schizophrenia - sharing distressing thoughts whilst demonstrating a flat affect or laughing
Thought:
Can be described in terms of:
Form
Content
Possession
Thought form:
Speed - e.g. racing thoughts in mania
Flow and coherence:
Loose associations - moving rapidly between topics with no apparent connection
Circumstantial - irrelevant details
Tangential - digressions from main subject
Flight of ideas - fast, pressured speech with ideas running into one another
Thought blocking - sudden cessation of thought
Perseveration - repetition of a response despite the removal of the stimulus
Neologisms - makes up words
Word salad - random string of words without relation
Thought content:
Delusions - firm, fixed belief based on inadequate grounds e.g. persecutory delusions and grandiose delusions
Obsessions - thoughts, images or impulses that occur repeatedly and feel out of the persons control
Compulsions - repetitive behaviours that patient feels compelled to perform
Overvalued ideas - solitary, abnormal belief that is neither delusional nor obsessional but preoccupying to the extent of dominating the persons life e.g. perception of being overweight in a patient with anorexia
Suicidal thoughts
Homicidal thoughts
Thought possession:
Thought insertion - thoughts inserted into patients mind
Thought withdrawal - thoughts removed from their mind
Thought broadcasting - others can hear their thoughts
Perception:
organisation, identification and interpretation of sensory information
Hallucinations
Pseudo-hallucinations - same as hallucinations but the patient knows it is not real
Illusions - misinterpretation of external stimulus
Depersonalisation
Derealisation
Cognition:
Should develop a vague idea of the patients cognition throughout the MSE - whether they are orientated, attention span and short term memory
A formal assessment can be done via:
Mini-mental state exam (MMSE)
Abbreviated mental test score (AMTS)
Insight and judgement:
Insight - ability of a patient to understand that they have a mental health problem and what they are experiencing is abnormal
Judgement - ability to make considered decisions or come to a sensible conclusion when presented with information e.g. asking "what would you do if you could smell smoke in your house?" - a patient with impaired judgement may suggest ignoring it
Risk:
Risk to self - any thought of harming themselves and whether they plan to act on these thoughts
Also ask about other risks to self - substance misuse, self-neglect
Risk to others - are they having any thoughts or made any plans to harm others
