Complications of Encephalitis

Many people who have encephalitis make a full recovery but sometimes the brain has been permanently damaged (acquired brain injury) and this causes long-term effects that are very serious.

Some of the complications include: 

  • problems with balance,
  • weakness in part or parts of the body,
  • loss of control of movement, 
  • loss or sensitivity in the senses e.g. touch, taste, hearing, sight and smell,
  • slurred speech, 
  • epileptic seizures (fits),
  • prolonged headache,
  • dizziness, and
  • nausea.

Other changes that may occur include: 

  • fatigue,
  • mood swings,
  • depression,
  • feeling anxious, frustrated and angry,
  • feeling more emotional than usual or emotionally numb, 
  •  no motivation or enthusiasm,
  • memory problems e.g. not remembering events before your illness, 
  •  talking about events that have never happened and imagining or confusing facts,
  • forgetting that you have done something e.g. put the kettle on, and
  • finding it difficult to concentrate.

Following the illness a period of convalescence lasting weeks or months is needed allowing the brain some time to make recovery.
