MENTAL STATE EXAMINATION (MSE) *PURPOSE: To reach a tentative diagnosis. It is the diagnosis of general cerebral functions. Designed to detect abnormal functions. An experienced nurse can complete all the MSE. Important information can be taken from first sight (when entering the room, sitting or talking. Also, level of consciousness can be observed.

1. GENERAL APPEARANCE: Good indicator of pts. overall mental functioning. It includes weight, height and general body built. A.Nutritional Status: Poor nutrition can result from medical or psychiatric disorders. In anorexia nervosa pt. is emaciated but still thinks she is fat.

In schizophrenia: pt. may use strange items for dress e.g. antennas, bags to protect them from the control of space people.

C. Eye contact: People usually maintain eye contact when they speak & track movement & gestures of interviewer. Abnormal eye movements can be diagnostic: -Wandering eyes show distractibility, visual hallucinations, mania or organic states. -Avoidance of eye contact may be due to hostility, shyness, or anxiety. -If pt. is suspicious, he tracks your movements and looks to every gesture.

2. PSYCHOMOTOR BEHAVIOR: A.Psychomotor activity: Reduced in depression & catatonic schizophrenia or increase in mania. B. Posture: The way pt. sits, walks, and behaves. C. Facial Expression: Sad face in depression, mask face of Parkinsonism.

D. Activity level: Restlessness in anxiety. Agitation in some depressed patients. Excitement in mania. E. Abnormal movements: Voluntary: such as the mannerisms of the schizophrenia or bizarre movements also seen in schizophrenia. Involuntary: such as hand tremor in anxiety.

3. MOOD AND AFFECT: A.Mood: The pervasive and sustained emotion that colors the person's perception of the world. In depression: pt. sees the world through dark glasses.

B. Affect: External expression of emotional responsiveness. What is observed in pt.'s facial expression & expressive behavior in response to internal or external stimuli. Evaluated for its intensity, duration, appropriateness to situation, range of affective expression, and control. In schizophrenia: blunted (flat), restricted, or inappropriate to situation. In mania: expansive and out of control. In hysterical pts.: labile affect that changes from extreme happiness to extreme sadness in minutes.

4. SPEECH: A.Amount of Speech: Increased in mania and anxiety states were the pt. is talkative. Pt. with mania may experience a pressure to speak continuously. Pt. with depression speaks very little and brief. B. Speed: Anxious pt. speaks rapidly. Depressed pt. speaks slowly.

C. Concentration: Ability to keep ones attention on a certain task. See if the patient can subtract 7 from 100 and notice his effort and time taken to perform this task. Impaired in mania were the pt. is distractible by minor stimuli and in anxiety states.

D. Memory: Ability to recall information. It is divided into: -Immediate: ask pt. to repeat 6 digits in the same order (within seconds to less than a minute). -Short term: tell pt. three items and ask him to repeat them after 5 to 10 minutes. -Long term: ask pt. what he did yesterday. -Remote: ask pt. about information in his childhood, school…

E. Abstract thinking: Ability to deal with concepts. Ask pt. to explain a known proverb or the similarity between two things.
