In patients with herpes simplex encephalitis, electroencephalograph may show sharp waves in one or both of the temporal lobes called paroxysmal lateral epileptiform discharges. These waves are present even before changes can be picked by Ct scan or MRI and are positive in majority of cases. However, these are not diagnostic of encephalitis
