Encephalitis is an inflammation of the brain that is often caused by a viral infection. This infection often causes only mild flu-like signs and symptoms or no symptoms at all. Sometimes the flu-like symptoms are more severe. Encephalitis can also cause seizures, confused thinking, or problems with movement. In some cases, this infection can be life-threatening.
The most common causes of Encephalitis may include:
1. Epidemic Encephalitis
Enterovirus can enter your gastrointestinal tract or respiratory system and cause infection which may travel to the central nervous system. As a result, it may cause the death of neurons. On the other hand, arboviruses enter your bloodstream when an infected insect bites you. The symptom of this infection may include light sensitivity and extreme weakness.
2. Sporadic Encephalitis
Childhood is the most common time to contract Herpes simplex type 1 and type 2. The disease is characterized by sporadic encephalitis and occurs most often in people aged 20 to 40. People who suffer from this infection have similar symptoms to those of other forms of encephalitis, but they can also be unconscious.
3. Autoimmune Encephalitis
This is a noninfectious type of encephalitis. It can be a cause of an autoimmune disorder that has been triggered by an infection.
NMDA-receptor encephalitis is the most common type of autoimmune encephalitis. It is the early stages of a viral illness.
Your healthcare provider might order tests, perform a medical exam, and discuss your medical history to diagnose encephalitis. Your doctor may ask about your vaccinations, recent colds, or other gastrointestinal or respiratory issues. You should tell your doctor if you have recently been bitten by a tick, if you have been around pets or other animals, and if you have traveled to certain places.
