Encephalitis is a very severe infection caused by the inflammation of the brain tissues. When encephalitis occur with meningitis, it is called meningoencephalitis. It is caused either as a direct infection or a sequela of a pre-existing condition. 
Encephalitis is caused by any of the following factors; 
- Viral infection, e.g rabies virus, HSV, poliovirus, mealses virus, bunyavirus, reovirus, etc 
- Bacterial infection, e.g mycoplasma, Lyme disease, Bartonella henselae, malaria, etc can result in encephalitis especially in immuno-compromised individuals.
- Autoimmune disorders
- Some types are of unknown aetiology
An adult infected with the disease typically present with; 
- Seizures or convulsions
- Memory problems
An infant may present with; 
- Poor appetite
Encephalitis can be diagnosed using any of the following procedures; 
- Magnetic Resonance Imaging (MRI) to detect the inflammation
- Electroencephalography (EEG) to monitor the electrical activity of the brain
- Lumbar puncture (spinal tap)
- Urine analysis
- Blood test
These may include; 
- Antiviral medications (for viral infection)
- Antibiotics (for bacterial infection)
Physiotherapy Management / Interventions
- Exercise therapy
- Gait rehabilitation
- Manual therapy
- Passive motion procedures
- CNS vasculitis
- Subdural empyema
- Meningeal carcinomatosis
