Herpes simplex encephalitis in the elderly
Herpes simplex encephalitis in the elderly is a common sporadic viral encephalitis. It is also called herpes simplex virus encephalitis, which can be seen in both primary herpes simplex virus infection and recurrent patients. The pathogen herpes simplex virus (HSV) is divided into type I and type II. Type I HSV lurks in the olfactory bulb, olfactory tract and trigeminal sensory ganglion, and type I is more common in adults and the elderly. Type II virus is mainly seen in newborns and is related to infection of the reproductive tract. This disease belongs to the category of febrile disease and spasm syndrome in traditional Chinese medicine.
