Reemergence of Neurological Deficit with Hyponatremia—When Obvious Is Not True

Abstract

Transient worsening of residual neurological deficit or recurrence of previous neurological deficit has been observed in patients with previous stroke. Recurrent stroke or transient ischemic attack (TIA) are frequent causes with a cumulative recurrence rate around 5.4% at 1 year.[1] Other causes may include Todd's paralysis, metabolic causes like hyponatremia, hypotension or infections, and use of sedative drugs.[2] [3] Herein, we report a case of transient reemergence of old stroke deficit with review of literature.
