Clinically Relevant Anatomy[edit|edit source]
Meningesare 3 thin layers that cover and protect the brain and spinal cord. They are the dura matter, arachnoid matter and pia matter. These meninges provide a support system for blood vessels, nerves, lymphatics and the cerebrospinal fluid that surrounds your central nervous system[1]. Meningoencephalitis is a neurological condition resembling bothmeningitis,which is the inflammation of themeninges, andencephalitis, which is the inflammation of the brain tissue[2].
Pathological Process[edit|edit source]
Meningoencephalitis is the result of direct embolization to meningeal vessels, with subsequent parenchymal or cerebrospinal fluid (CSF) invasion of the infecting organism[3].
Causes[edit|edit source]
Meningoencephalitis is caused by various bacterial, viral and protozoan infection. Some of them are;[4]
- Listeria monocytogenes
- Neisseria meningitidis
- Rickettsia prowazekii
- Mycoplasma pneumoniae
- Tuberculosis
- Borrelia (Lyme disease)
- Leptospirosis
- Tick-borne meningoencephalitis
- West Nile virus
- Measles
- [Epstein-Barr Virus|Epstein-Barr]] virus
- Varicella-zoster virus
- Enterovirus
- Herpes simplex virus type 1
- Herpes simplex virus type 2
- Mumps virus
- HIV
- Primary amoebic meningoencephalitis, e.g., Naegleria fowleri, Balamuthia mandrillaris, Sappinia diploidea
- Trypanosoma brucei
- Toxoplasma gondii (sporozoa)
Prognosis[edit|edit source]
As the disease is a combination of two very serious neurological conditions, it is linked with severe morbidity and high mortality rate.
Clinical Presentation[edit|edit source]
Patients present with symptoms of both meningitis and encephalitis.
Diagnosis[edit|edit source]
Meningoencephalitis can be dignosed through any of the following like meningitis and encephalitis;
- Magnetic Resonance Imaging (MRI)
- Electroencephalography (EEG)
- Lumbar puncture (spinal tap)
- Urine analysis
- Blood test
Management / Intervention[edit|edit source]
干预是一般症状,可能包括ude various management strategies of meningitis and encephaliti depending on which symptoms are expressed as related to both medical and Physiotherapy managements.
