The symptoms of SLE can range from mild to severe. Mild cases may present with fever, headache, dizziness, and nausea. Severe cases, however, can lead to encephalitis (inflammation of the brain), which may result in symptoms such as high fever, neck stiffness, stupor, disorientation, coma, tremors, and even paralysis. In rare cases, SLE can be fatal, particularly in elderly individuals.
