An Algorithm for the Evaluation of Peripheral Neuropathy - Article

ABSTRACT: The diagnosis of peripheral neuropathies can be frustrating, time consuming and costly. Careful clinical and electrodiagnostic assessment, with attention to the pattern of involvement and the types of nerve fibers most affected, narrows the differential diagnosis and helps to focus the laboratory evaluation. An algorithmic approach to the evaluation and differential diagnosis of a patient with peripheral neuropathy is presented, based on important elements of the clinical history and physical examination, the use of electromyography and nerve conduction studies, autonomic testing, cerebrospinal fluid analysis and nerve biopsy findings. The underlying cause of axonal neuropathies can frequently be treated; demyelinating neuropathies are generally managed with the assistance of a neurologist.


Peripheral Neuropathy: Differential Diagnosis and Management - Article

ABSTRACT: Peripheral neuropathy has a variety of systemic, metabolic, and toxic causes. The most common treatable causes include diabetes mellitus, hypothyroidism, and nutritional deficiencies. The diagnosis requires careful clinical assessment, judicious laboratory testing, and electrodiagnostic studies or nerve biopsy if the diagnosis remains unclear. A systematic approach begins with localization of the lesion to the peripheral nerves, identification of the underlying etiology, and exclusion of potentially treatable causes. Initial blood tests should include a complete blood count, comprehensive metabolic profile, and measurement of erythrocyte sedimentation rate and fasting blood glucose, vitamin B12, and thyroid-stimulating hormone levels; specialized tests should be ordered if clinically indicated. Lumbar puncture and cerebrospinal fluid analysis may be helpful in the diagnosis of Guillain-Barré syndrome and chronic inflammatory demyelinating neuropathy. Electrodiagnostic studies, including nerve conduction studies and electromyography, can help in the differentiation of axonal versus demyelinating or mixed neuropathy. Treatment should address the underlying disease process, correct any nutritional deficiencies, and provide symptomatic treatment.
