Which part of the body is primarily affected by encephalitis?

Encephalitis is primarily an inflammation of the brain, making the brain the key area that is affected by this condition. The inflammation can be caused by various factors, including viral infections, bacterial infections, autoimmune responses, or other health issues. Because of this inflammation, patients may experience a range of neurological symptoms such as headaches, fever, confusion, seizures, and in severe cases, it can lead to significant complications including neurological deficits or even death.

Understanding the specific impact of encephalitis on the brain is crucial for identifying appropriate treatments and interventions. This condition highlights the sensitivity of brain tissue and its vulnerability to infections and inflammatory processes, which can disrupt normal brain function. Other organs listed, such as the liver, lungs, and heart, while they can be affected by various infections or diseases, are not the primary targets of encephalitis.
