herpes simplex encephalitis
Noun: A severe viral infection of the brain, specifically an acute encephalitis, most frequently caused by the herpes simplex virus type 1 (HSV-1). It is characterized by inflammation that typically affects the temporal and frontal lobes of the brain.
This is a medical term used in clinical and scientific contexts to describe a specific, serious neurological condition. * Early diagnosis of herpes simplex encephalitis is critical for effective treatment with antiviral drugs. * The patient was admitted with symptoms suggestive of herpes simplex encephalitis, including fever, confusion, and seizures.
- The term is often abbreviated as HSE in medical literature and clinical notes.
- While herpes simplex encephalitis is most commonly associated with HSV-1, a similar condition can be caused by herpes simplex virus type 2 (HSV-2), particularly in newborns.
- HSE: The standard acronym for herpes simplex encephalitis.
- Herpetic encephalitis: A synonymous term often used interchangeably with herpes simplex encephalitis.
- Encephalitis: The general term for inflammation of the brain, of which herpes simplex encephalitis is a specific type.
- Meningoencephalitis: A related condition involving inflammation of both the brain and the meninges (the membranes covering the brain).
- Herpetic encephalitis
- Acute necrotizing encephalitis (This describes the severe, tissue-damaging nature of the infection.)
This term refers exclusively to the neurological infection caused by the herpes simplex virus. It is distinct from other forms of encephalitis and from less severe herpes infections, such as cold sores (caused by the same virus). The defining feature is the viral attack on brain tissue, particularly in the specified lobes.
