Crossing diagnostic borders: herpes encephalitis complicated by cultural and language barriers.

BACKGROUND

The patient who complains of vague mental status changes requires extra vigilance in that the underlying condition might itself affect the patient's ability to communicate well and relate a medical history. The differential diagnosis of delirium is broad, ranging from the benign to the potentially fatal. The diagnostic uncertainty inherent in primary care is compounded when language and cultural differences interfere with physician-patient communication.

METHODS

We undertook a MEDLINE-assisted review of the medical literature concerning herpes simplex encephalitis. Additionally, we performed an Internet search of several government Web sites to find current legal and federal guidelines concerning the use of medical interpreters.

RESULTS AND

CONCLUSIONS

We recount the case of a young Eastern European immigrant who complained initially of vague mental status changes and was found to have herpes simplex encephalitis. Diagnosis could have been made sooner had the physician been familiar with the patient's baseline mental status or had cultural and language barriers not stood between the physician and the patient and his mother. Herpes simplex encephalitis is a rare, but specific, cause of delirium for which prompt diagnosis and treatment with intravenous acyclovir can prevent death or serious sequelae.
