Rationale:

  • Findings may support WNV neuroinvasive disease or may rule in or rule out other diseases.

Evidence:

  • EEGs showed electrographic seizures, focal sharp waves, and diffuse, irregular slow waves in some patients with encephalitis in a 2002 Louisiana case series (30).
  • EMGs in patients with neuromuscular weakness suggested pronounced anterior horn cell or motor axonal injury in a 2002 Canadian case series (29).
  • NCS and EMGs in WNV-seropositive patients in a 2002 Louisiana case series had findings compatible with severe asymmetric processes affecting anterior horn cells and/or motor axons in patients with asymmetric weakness (30).

Comments:

  • None.
