Encephalitis
Moderate
Encephalitis is inflammation of the brain that can cause a serious illness affecting the nervous system. Symptoms may include fever, headache, confusion, unusual behavior, seizures, sensitivity to light, weakness, difficulty speaking, or loss of consciousness. Encephalitis can progress rapidly and may require urgent hospital treatment. Recovery varies according to the cause and severity of the inflammation.

Overview
Encephalitis is inflammation of the brain that can cause a serious illness affecting the nervous system. Symptoms may include fever, headache, confusion, unusual behavior, seizures, sensitivity to light, weakness, difficulty speaking, or loss of consciousness. Encephalitis can progress rapidly and may require urgent hospital treatment. Recovery varies according to the cause and severity of the inflammation.
Symptoms 4
Confusion
Fever
Headache
Seizures
Causes
Encephalitis may be caused by infections, particularly viruses, or by an abnormal immune response in which the immune system attacks brain tissue. Several viruses can cause encephalitis, including some transmitted by mosquitoes or ticks. Less commonly, bacterial, fungal, or parasitic infections can be involved. Autoimmune encephalitis occurs when immune-system activity causes inflammation without a direct infection of the brain.
Risk Factors
Risk depends on the underlying cause. Exposure to viruses and other infectious organisms can increase risk, including exposure through mosquito or tick bites or contact with infected people. Travel or residence in areas where certain mosquito- or tick-borne infections occur may also increase risk. People with certain immune-system disorders may be susceptible to autoimmune encephalitis. Age and overall health can influence the severity of illness.
Diagnosis
Diagnosis is based on a patient's medical history,
symptoms, physical examination and, when necessary,
laboratory or imaging investigations.
Encephalitis is diagnosed using the symptoms, neurological examination, and tests designed to identify inflammation or infection of the brain. Evaluation may include brain imaging with CT or MRI, analysis of cerebrospinal fluid obtained by lumbar puncture, blood tests, and an electroencephalogram to assess brain electrical activity. Additional antibody or infectious-disease testing may be performed to determine the cause.
Prevention
Key Prevention Tips
Prevention depends on the cause
Recommended vaccinations can protect against some infections associated with encephalitis
Avoiding mosquito and tick bites through appropriate clothing, repellents, and environmental precautions can reduce exposure to certain infectious causes
Good hygiene can reduce transmission of some viruses
People should seek urgent medical attention for severe headache, confusion, seizures, or other rapidly developing neurological symptoms
Prevention Guidance
Prevention depends on the cause. Recommended vaccinations can protect against some infections associated with encephalitis. Avoiding mosquito and tick bites through appropriate clothing, repellents, and environmental precautions can reduce exposure to certain infectious causes. Good hygiene can reduce transmission of some viruses. People should seek urgent medical attention for severe headache, confusion, seizures, or other rapidly developing neurological symptoms.
Reminder: Prevention recommendations should be tailored to your personal health status and risk factors.
