question: I am looking for information on the treatment for Saint Louis encephalitis after the anti virals have been given with no improvement.   My son has had this disease since August, it was not properly diagnosed until early October. His symptoms remain the same, unbearable headaches, dizziness, sometimes numbness in his face throat and arms, slurred speech, memory loss, his eyes are very sensitive, he cannot tolerate light.To date the treatment recommended is rest and fluids, the body will heal itself.
