Q

Mental status exam technique

A

-orientation: person, place, time
 Mental status is addressed in the history and monitored as patient demonstrates the ability to follow directions during examination
 The MMSE (Mini-Mental State Exam)
 A more detailed mental status exam requires more time, and should evaluate level of consciousness, attention, memory, language, visuospatial skills, executive function, and emotion and personality
