BACKGROUND Herpes virus infections can cause cognitive impairment during and after acute encephalitis. Although chronic, latent/persistent infection is considered to be relatively benign, some studies have documented cognitive impairment in exposed persons that is untraceable to encephalitis. These studies were conducted among schizophrenia (SZ) patients or older community dwellers, among whom ...

Herpes simplex encephalitis is a potentially fatal infection of central nervous system that typically involves frontal and temporal lobes. Occasionally, it presents an extratemporal involvement and in rarer cases, it is limited to the brainstem. We describe a case of an adolescent who presented with fever, sore throat, and vertigo. Clinical picture evolved to lethargy, tetraparesis, consciousne...

A case of herpes encephalitis is reported in a patient who had cranial irradiation and high dose steroids for a cerebral neoplasm. Before radiotherapy the patient had had herpetic infections of the skin and eye.

Widespread neurological disorders following herpes zoster are exceptional. They include encephalitis and myelitis, and a type of polyneuropathy. The latter is particularly rare as only 16 cases have been described since the first account by Wohlwill in 1924. We present two clinical cases of polyneuropathy following herpes zoster with neuropathological studies on one of them, and discuss its pos...

BACKGROUND Encephalitis is associated with significant mortality and morbidity, but its cause remains largely unknown. We designed a national prospective study in France in 2007 to describe patients with encephalitis, investigate the etiologic diagnosis of encephalitis, and assess risk factors associated with death. METHODS Patients were enrolled by attending physicians according to case defi...

Antibodies to different viruses and bacteria were measured in the cerebrospinal fluid (CSF) of six patients with herpes simplex virus encephalitis proven by brain biopsy and in five others with a presumptive diagnosis. Antibodies to herpes simplex virus but not to other organisms appeared in the CSF of all patients after the first weeks of the illness. Herpes simplex virus antibodies were not f...

Herpes simplex encephalitis is a rare disease. In adults, most of the reported cytomegalovirus (CMV) infections are seen in immunocompromised patients. We present a case of 67-year-old Chinese male with the coinfection of CMV and herpes simplex virus type II (HSV-II). He had no history of being treated with immunosuppressants, showed symptoms of psychosis and was scored 109 on the Positive and ...

The authors report on a case of concurrent herpes simplex encephalitis (HSE) and malignant glioma. The co-occurrence of HSE and malignant glioma is very rare, but it can occur during glioma treatment. Both radiotherapy and chemoradiation with temozolomide can induce viral reactivation, leading to HSE relapse. Careful observation for HSE is necessary when administering chemoradiation to patients...

Cases of herpes zoster are not rare in everyday medical practice and the various neurological complications, such as post-herpetic neuralgias, are well known. Myelitis or encephalitis, on the other hand, are much rarer complications. The following case admitted to the Neuropsychiatric Clinic of the University of Salonica is of special interest because of the focal cerebral lesions, which are ve...
