Peripheral Neurology: Case Studies in Electrodiagnosis

Peripheral neurology: special concerns in the elderly.

Changes in the peripheral nervous system produce a major impact on safety and quality of life in the elderly. The chal­ lenges of aging reflect alteration of both neuromuscular and sensoty function. Of particular concern are motor and prop­ rioceptive deficits increasing the risk of falls. In addition, changes in sensoty path­ ways may predispose the elderly to neu­ ropathic pain. This review w...

How electrodiagnosis predicts clinical outcome of focal peripheral nerve lesions.

This article reviews the electrodiagnostic (EDX) prognostic factors for focal traumatic and nontraumatic peripheral nerve injuries. Referring physicians and patients often benefit from general and nerve-specific prognostic information from the EDX consultant. Knowing the probable outcome from a nerve injury allows the referring physician to choose the best treatment options for his/her patients...

Electrodiagnosis in Cranial Botulism

Botulism is an acute neurologic disorder that causes potentially life-threatening neuroparalysis resulting in weakness and laccid paralysis. In addition to the autonomic nervous system, botulism may involve only the cranial nerves, thus posing special diagnostic problems. Almost all cranial nerves are not easily testable. The anatomical and physiological characteristics of the spinal accessory ...

Ophthalmic Electrodiagnosis

Electrodiagnosis in neuromuscular disorders.

2. The normal sensori-motor nerve conduction with absent F-waves and tendon jerks of a moderately de-saturated semiconscious patient in the intensive care unit may be seen in: a. A classical pattern of critical illness myopathy involving both proximal and distal muscles b. Post-synaptic neuromuscular disorder c. The early stages of motor neuron disease (MND) (axonal loss) before the period of W...
