Functional recovery from neuroinvasive West Nile Virus: A tale of two courses

In 2012, the highest numbers of West Nile Virus (WNV) cases were reported by the Center for Disease Control since 2003. This outbreak included over half of the identified patients being classified with one of the more debilitating neuroinvasive subtypes of WNV. Despite improvements in diagnosis and treatment options in symptom management, longitudinal research on WNV neurocognitive and functional outcomes is limited by sample size, retrospective review, and/or reliance on self-report measures for cognitive status and level of independence. This study describes the cases of 2 patients diagnosed with WNV as they complete rehabilitation across the continuum of care.

Review of two cases that experience different rehabilitation outcomes 4-18 months post diagnosis.

The cases presented here demonstrate the potentially differential courses of recovery and outcomes for physical (e.g., balance, ambulation, upper extremity function), cognitive (e.g., attention, executive functions, memory, language, visuospatial), and emotional functioning, as assessed via measures administered by the patient's physical therapists and neuropsychologists. These patients were evaluated as part of the standard clinical practice to monitor changes, track recovery, and provide recommendations across the continuum of care from admission to discharge from acute inpatient rehabilitation, during outpatient day neurorehabilitation, and while receiving outpatient neuropsychology services.

These cases highlight the variability in rehabilitative course for individuals diagnosed with WNV. Consistent follow-up with patients is recommended to ensure management of remitting and chronic symptoms.
