MENTAL STATUS EXAM

  • The bare minimum: During the interview, look for difficulties with communication and determine whether the pt has recall and insight into recent and past events.

The mental status examination is underway as soon as the physician begins observing and talking with the pt. The goal of the mental status exam is to evaluate attention, orientation, memory, insight, judgment, and grasp of general information. Attention is tested by asking the pt to respond every time a specific item recurs in a list. Orientation is evaluated by asking about the day, date, and location. Memory can be tested by asking pt to immediately recall a sequence of numbers and by testing recall of a series of objects after defined times (e.g., 5 and 15 min). More remote memory is evaluated by assessing pt's ability to provide a cogent chronologic history of the illness or personal life events. Recall of historic events or dates of current events can be used to assess knowledge. Evaluation of language function should include assessment of spontaneous speech, naming, repetition, reading, writing, and comprehension. Additional tests such as ability to draw and copy, perform calculations, interpret proverbs or logic problems, identify right vs. left, name and identify body parts, etc., are also important.

A useful screening examination of cognitive function is the mini-mental status examination (MMSE) (Table 191-1).
