MSE of a bipolar patient
Appearance and behaviour – Perhaps flamboyant or revealing clothing, irritability,
psychomotor agitation, over-familiar behaviour.
Speech – pressured speech which is difficult to interrupt, loud speech, copious/excessive
speech.
Mood – May be excessively happy or excitable, or may be irritable and easily angered.
Thoughts – Thought disorder in the form of flight of ideas. May describe racing thoughts,
grandiose thoughts, persecutory beliefs most often related to their own perceived special
status/abilities (e.g. others jealous of them or after their ideas). Thoughts of harm to self or
others may occur secondary to delusional beliefs. Delusional beliefs are usually mood
congruent.
Perceptions – Perceptual abnormalities are less common than in schizophrenic type illnesses
(if psychosis is a predominant feature, the diagnosis of schizoaffective disorder may be
considered).
Insight likely to be diminished
