Guidelines for Performing, Recording, and Presenting
the Neurologic History and Physical Exam

HISTORY

1. Chief Complaint (record on note and verbally present)

The Chief Complaint should begin every written and oral presentation. It should include the patient's age, sex, presenting symptoms and the duration of symptoms. Ideally, the chief complaint should come from the patient directly. If that is not possible, then the chief complaint may come from a family member, friend, EMT or referring physician. The source should be documented if not the patient.

2. History of Present Illness (record on note and verbally present)

The history of present illness is a chronologic history of the patient's symptoms and evaluation starting from the beginning (e.g., the patient was well until...). Ask the patient to walk you through exactly what happened. Often, small details separate the history of an embolic from a thrombotic stroke; the headache of subarachnoid hemorrhage from migraine. Attention should be given to the temporal course, severity, associated symptoms, provoking factors, and alleviating factors. Pertinent past medical history, family history and social history can be included in this section only if directly relevant (e.g., for a patient with a suspected TIA, inclusion of cardiac and peripheral vascular disease is appropriate). Otherwise, this information is left for later. It is essential to get the history of present illness as complete and accurate as possible. If the history is not obtainable from the patient, the student needs to get on the phone and get the information from wherever possible, including the family, co-workers and treating doctors.

3. Past Medical and Surgical History (record on note and verbally present)

List all major ongoing and past medical, psychiatric and surgical problems. Often, it is helpful to review with the patient the times he/she has been admitted to a hospital for any reason.

4. Medicines and Allergies (record on note and verbally present)

As many neurologic conditions, especially confusion, altered mental state and weakness, can be due to medicine side effects, this category is very important. Get a complete list, including medicines which have recently been discontinued as well. In addition, ask above over the counter medicines and vitamins. In women, ask about oral contraceptives, as this might not be considered a medicine, per se.

Record all allergies to medicines and their reactions (e.g., rash).

Note: some patients may report side effects as allergies.

5. Family History (record all on note, but verbally present only pertinent positives)

Record the age, any serious illness and cause of death of close family members. Ask specifically if anyone else in the family has any type of neurologic condition.

6. Social History (record on note , but verbally present only pertinent positives)

Include Education; Occupational history (current employment status, previous jobs); Marital status/family situation; Life style/habits (alcohol, tobacco, drugs); any potential toxic exposure from work or home.

7. Review of Systems (record on note, but verbally present only pertinent positives)

Ask about all other major systems. Record all pertinent positive and negatives. Include constitutional symptoms (especially fever, sweats, weight change), skin, respiratory, breast, cardiovascular, gastrointestinal, endocrine, musculoskeletal, psychological and genitourinary systems.

GENERAL PHYSICAL EXAMINATION

The physical examination the neurologic patient is the same physician examination for any other medical or surgical patient with an emphasis on the neurologic examination.
The general physical examination should include:

     General appearance
     Vital signs
     Skin
     Lymph nodes
     Head, eyes, ears, nose and throat
     Chest - heart, lungs, breasts
     Vascular
     Abdomen
     Back
     GU
     Extremities
 
Other than the general appearance and the vital signs, only the pertinent positives and negatives should be verbally presented.


NEUROLOGIC PHYSICAL EXAMINATION

The Neurologic exam on every patient must include assessment of the mental state, cranial nerves, motor system, reflexes, sensory system and coordination/gait. All tests do not need to be performed on all patients. However, each major area must be screened on all patients. Additional testing can then be performed depending on the patient's symptoms (e.g., more detailed mental state testing is indicated in a patient with memory loss; likewise, more detailed sensory testing is required in a patient with a peripheral nerve injury).

LABORATORY DATA

The laboratory data should be listed. It needs to be complete, accurate and organized. Laboratory data may include blood tests, CSF studies, EKG, radiology and any clinical neurophysiology (e.g., EMG, EEG). Attention should be given to any abnormal results.

ASSESSMENT, PROBLEM LIST AND PLAN

The patient assessment should summarize the key points from the history and physical followed by a problem list and plan. The first problem listed should be the problem that has resulted in the patient being admitted to the hospital or the reason for referral. This problem should be followed by an assessment that lists and discusses the most likely diagnoses for the problem. In the neuroscience clerkship, it is essential to discuss the localization of the problem within the neuraxis. The resultant discussion should demonstrate your skills in integrating clinical information from the patient. The discussion should include management plans that includes plans for further rational diagnostic studies, treatments and patient education.

Judgement should be used in the degree of detail provided about other active problems. The plan may vary depending if the patient is seen on the ward, the consult service or in the outpatient clinic. In the modern day, it is often important to consider discharge planning early, especially for anticipated rehabilitation or skilled nursing needs. Likewise, it is essential to identify the primary care physician and ensure they are kept informed.

VERBAL PRESENTATION

The ability to clearly present a case is one of most important skills to master during the core clerkships. The challenge is to be precise and to the point. Pertinent positives and negatives need to be mentioned; the remainder can be included in the written note. The focus of the presentation is the history of present illness. After the history, the listener will have internally generated a list of questions and hypotheses which can then be further narrowed from information gleamed by the physical examination. A busy service could not operate if every patient presentation took an hour. Once mastered, the entire neurologic history and physical examination should be able to be presented in the range of 5-10 minutes.
