The Mental State Examination & MMSE
By Dr A McLeod



The mental state examination is the psychiatric equivalent of the physical examination - it often confuses medical students in exams as usually exams have the pattern: history then exam.

In psychiatry the boundary is less easy to spot.
One mnemonic for remembering the MSE is A Brainy Senior Medic Seriously Thought Pete Cog Got It Right

A Appearance
Neat / untidy / eccentric / unsuitable etc. Bear in mind cultural norms

Brainy Behaviour
Appropriateness
Responding to hallucinations
Body language: aggressive, sexual, histrionic etc.
Senior Speech
Rate e.g. pressure of speech (hypomania) or poverty (depression)
Volume
Difficulty speaking e.g. indicative of aphasia / dysphasia or dysarthria
Neologisms - words invented by the patient
Flow e.g. sudden stops (possible thought block) or rapid shift of topic (possible flight of ideas)

Medic Mood
Mnemonic = MAID - Moody And In Depression
Mania - spending money; gambling; libido
Anxiety - continuous or with a trigger; what trigger; getting worse?
Irritation - continuous or with a trigger; what trigger; getting worse?
Depression - appetite; sleep; hobbies and interests; feelings of worthlessness; memory and concentration

Always note subjective (patient's view) and objective mood

Seriously Suicidal Ideation
NOTE:
There is a false belief that asking about suicide may 'put the idea into the patients head'. There is no evidence that this is the case - asking about suicidal ideation is rather an important part of the management of risk in vulnerable patients.

You can start off with 'have you ever thought of harming or kiling yourself?' - some schools of thought feel this to be a bit direct and advocate something like 'have you ever had dark thoughts?' and then elaborating if the answer is positive.

Self harm

Method - knife, tablets
Intent  - relief of anger or stress; to die

Suicide

Impulsive or carefully planned?
Inluence of alcohol or drugs?
What method was used
What stopped it being successful - did the patient take any steps to ensure success
What was the aim (to die, to get attention etc.)
Does the patient regret the attempt?
Is there an intent to repeat? - ask how this would be done
Thought Thoughts
Stream of thought
Normal thought is like a calmly running stream - in abnormal states it may rush like floodwater (pressure), flow like a sluggish drip of water in a drought (poverty of tought); or be stopped temporarily by dams (though block). 
  • Pressure of thought is expressed through pressure of speech - a rich flow of ideas is expressed at speed.
  • Poverty of thought is expressed though poverty of speech - thoughts and ideas seem to be slow and sluggish in coming.
  • Thought block may be seen if speech stops suddenly in mid flow - often multiple times. Even if this is not observed you can ask: "do thoughts ever seem to vanish from your head?"; "where do they go". Those with thought block may attribute this phenomenon to someone else 'stealing' their thoughts.

Form of thought
Where stream of though can be thought of as the speed and volume of thoughts, form of thought is the content - what the thoughts and ideas actually are. As with stream of thought, these will mostly be detected through the patients speech.
  • Loosening of associations: is a loss of the normal structure of thinking. Thoughts move from one to another by abnormal paths that are diffuicult or impossible to follow:
    • Knight's move thinking (named after the move of the chess piece of that name) is thinking that seems to arrive at a conclusion with no logical pathway for getting there, or moving rapidly between thoughts that appear unlinked. You can only discern Knight's move thinking through what the patient says in assessment.
    • Talking past the point (Vorbeireden): the patient talks but never gets to the point - they may get near it and veer of to another matter.
    • Verbigeration: this is the deterioration of speech to senseless repetition of words and sounds. When especially severe it is called word salad.
  • Flight of ideas is the rapid progression from one thought to another - again it can be seen only though what the patient says - he will move from one topic to another. Unlike Knight's move thinking, the link between the topics can be seen by most observers - these links may take the form of Clang associations, puns, or rhymes.
    • Clang associations: words that sound the same - these are used as jumping points to a new concept e.g. "... and then I rang the bell sell - that's what I used to do - I worked at a little shop in town brown was always my favourite colour..."
    • Puns: words that have several different meanings used as jumping points to different ideas. 
    • Rhymes
  • Other problems in form of thought
    • Overinclusion: this is the inability to preserve conceptual boundaries, so that extra irrelevant items become incorporated in concepts, rendering the patient's thinking less precise and more abstract.
    • Neologisms: these are new words created by the patient - often to describe symptoms. Before diagnosing neologisms exclude dialect, jargon and foreign language words. Ask where the word comes from. This is mostly found in schizophrenia.
    • Perseveration: this occurs when one thing that has been said my be repeated, often several times. e.g. a question may recieve a sensible answer but the next question yields the exact same answer and the next and so on. This is mostly found in schizophrenia.

Obsessions
  • "do you have thoughts that you can't get rid of?"
  • "what are these?"
  • "are they there all the time?"

Compulsions
  • "are there any actions that you have to do but don't want to?"
  • "what are these?"
  • "what happens if you try not to do these?"
  • "are they there all the time?"

Delusions (those below are first rank symptoms of schizophrenia)

  • Of thought withdrawal "do you think other people take thoughts from your head?"; "How do they do this?"; "Why do they do this?"
  • Of thought insertion "do you think other people put thoughts into your head?"; "do you think some of the thoughts in your head are not your own?" "How does this happen?"; "Why would someone do this?"
  • Of thought broadcast "do you think other people hear your thoughts withou you saying anything?" "How do they do this?"; "Why do they do this?"
  • Of control "Do you feel that something else controls your actions sometimes" ; "Who does this" ; "why do they do that?" ; "what do they try to make you do?" ; "Can you resist this control?"
  • See the delusions article for more (less common) types of delusion.

Pete Perceptions
Illusions
Hallucinations: Auditory, Visual, Somatic

Depersonalisation (alternately, this may be asked about under mood as it is often related to anxiety states) "Do you ever feel that you are not quite real"
Derealisation (alternately, this may be asked about under mood as it is often related to anxiety states) "Do you ever feel that the world around you is not quite real / lacks colour and reality / seems like it's behind a shield of glass"

Cog Cognition
Mnemonic = COMA: Concentration, Orientation, Memory, Attention
These are assessed by the MMSE (see below)

Got General IQ 
Assesed crudely by MMSE (see below) and general responses during interview.

It Insight
Does patient think they are ill; is the illness mental or physical; what is the cause of illness (do they think alcohol, relationships etc. may play a role); do they need treatment; are they willing to accept treatment?

In psychodynamic therapy, insight may be split into 'intellectual' and 'emotional' insight:
  • In intellectual insight the patient understands that they are ill and that treatment is needed but does not engage - it is akin to the 'new years resolution' a statement of intent with no real probility of being accomplished.
  • Emotional insight on the other hand is the intellectual components with a real emotional investment in improving and getting better and a concrete decision to engage with treatment and a belief that this will be successful.
Right Rapport
Is the patient engaging; making / avoiding eye contact?






The Mini-Mental State Examination



There are various forms of MMSE - the common ones are the 10 point and 30 point tests

The 10 point one is all you will be expected to use in Finals

The ten item mini-mental state examination is used to identify problems in cognition and general IQ
One version is:

I am going to ask you to remember this address for later: 42 West Register Street (ask patient to repeat it)

Each of the following score a single mark if correct

Concentration

Orientation

Memory

Attention

General IQ

A PDF of the 30 point test is available here.

Other tests that are useful for more advanced cognitive testing are the Clock Drawing test (see here - external site).
