Neurologic Examination

The neurologic examination is initiated on hospital admission or in

the field and is reassessed continuously, hourly or daily, as necessary.

The neurologic examination consists of patient history; mental status

examination; viral sign measurement; vision, motor, sensory, and

coordination testing; and diagnostic resring.

Patietlt History

A detailed history, initially taken by the physician, is often the most

helpful information used to delineate whether a patient presents with

a true neurologic event or another process (usually cardiac or metabolic in nature). The history may be presented by the patient or, more commonly, by a family member or person witnessing the acme or progressive event(s) responsible for hospital admission. One common

framework for organizing questions regarding each neurologic complaint, sign, or symprom is presented here7,8:

• What is the patient feeling?


When did the problem initially occur and has it progressed?


What relieves or exacerbates the problem?

• What is the onset, frequency, and duration of signs or symptoms?

In addition to the general medical record review (see Appendix 1-

A), questions relevant to a complete neurologic history include the

following:

• Does the problem involve loss of consciousness?


Did a fall precede or follow the problem?

What are the functional deficits associated with the problem?


Is there an alteration of speech?


Does the patient demonstrate memory loss or altered cognition?
