Acute confusion--an unusual form of cerebral herpes simplex virus infection?
Herpes simplex virus (HSV) infections are common and, if afflicting the central nervous system, may cause death or severe sequelae. Since specific therapy is now available there is an increasing demand for the recognition of the various ways in which cerebral HSV-infections may be manifested. This report describes a 15-year-old boy who presented acutely with mental symptoms of confusion, hallucinations and sleep disturbance. Simultaneously, but without any increase in cerebrospinal fluid cell or protein content, an intrathecal production of HSV-antibodies of transient nature was detected. These findings suggest that the patient may have suffered from an unusual form of herpes infection in the central nervous system. We suggest that similar cases should be thoroughly explored for possible herpes etiology as early as possible during the acute phase of the disease.
