INTRODUCTION

KEY CONCEPTS

  • Image not available. Accurate diagnosis of neurological disorders leads to effective pharmacotherapy.

  • Image not available. The clinical neurologic history and examination are the cornerstones of neurologic diagnosis and management.

  • Image not available. History and examination should be modified for the pediatric patient as appropriate.

  • Image not available. The neurologic history and examination are directed at localization of the disease process so that a differential diagnosis can be formed.

  • Image not available. After forming the differential diagnosis, appropriate testing helps pinpoint the correct diagnosis.

  • Image not available. Accurate diagnosis leads to appropriate therapy and management of neurologic conditions.

  • Image not available. Appropriate history taking and examination techniques are useful for monitoring and evaluating the pharmacotherapeutic plan.

  • Image not available. Lumbar puncture (LP) should only be performed when it can be done safely. Relative contraindications may include increased intercranial pressure, mass lesions, papilledema, and coagulopathies.

Collect

  • Patient characteristics (eg, age, sex, pregnant)

  • Patient medical history (personal, family, birth, and hhhhdevelopmental) (see section "Signs and Symptoms of Neurologic Disorders"; Table e70-1)

  • Social history (eg, tobacco/ethanol use)

  • Current and previous medications including nonprescription medications, herbal products, and dietary supplements (see section "Signs and Symptoms of Neurologic Disorders")

  • Objective data

    • Neurologic examination (ie, higher cortical function, cranial nerves, motor function, reflexes, cerebellar function, sensory function, and gait) (see section “The Neurologic Examination”; Table e70-2)

    • Blood pressure (BP), heart rate (HR), height, weight

    • Laboratory examinations as appropriate for the differential diagnosis and possibly including examination of the cerebrospinal fluid (CSF) (see section "Laboratory Findings for Neurologic Disorders and Their Interpretation"; Table e70-3; Fig. e70-1)

    • Imaging studies as appropriate (eg, computed tomography [CT] of head) (see section "Diagnosing Neurologic Anatomic Abnormalities")

    • Electrophysiology studies as appropriate (eg, nerve conduction velocities [NCV], electromyography [EMG], and electroencephalogram [EEG]) (see section "Assessing Neurologic Dysfunction")

Assess

  • Results of history and neurological examination

  • Ability/willingness to obtain diagnostic testing (eg, insurance coverage, travel, undergoing invasive testing)

  • Relative contraindications for lumbar puncture (see section "Laboratory Findings for Neurologic Disorders and Their Interpretation")

    • Relative contraindications for magnetic resonance imaging (MRI) (see section “Diagnosing Neurologic Anatomic Abnormalities”)

  • Emotional status (eg, presence of anxiety, depression)

Plan

  • Order appropriate diagnostic regimen

  • With established diagnosis, develop therapeutic plan (see disease-specific chapters)

  • Monitoring parameters including efficacy and safety of any therapies; frequency and timing of follow-up

  • Patient education regarding testing and diagnosis

  • Referrals to other neurology specialists when appropriate (eg, memory disorders, stroke)

Implement

  • Provide patient education regarding all elements of evaluation and treatment plan

  • Use motivational interviewing and coaching strategies to maximize adherence to any therapies

  • Schedule follow-up

Follow-up: Monitor and Evaluate

  • Resolution of neurologic symptoms

  • Presence of adverse effects of therapy

  • Patient adherence to treatment plan using multiple sources of information

  • Reevaluate as needed
