There are three nervous systems in the body, and SLE affects each differently, according to the Lupus Foundation of America, Inc. When the central nervous system, which is the brain and spinal cord, is affected by SLE, symptoms that may occur include headaches, vision problems, depression, confusion, seizures and difficulty concentrating.
The peripheral nervous system includes motor responses and sensation. Symptoms of SLE affecting the peripheral nervous system include facial pain, carpel tunnel syndrome, ringing in the ears, dizziness and eyelid drooping.
The autonomic nervous system is the body function regulator controlling bladder and bowel functions, muscle movement, heart rate, breathing, blood pressure and release of adrenalin. When SLE affects the autonomic nervous system, symptoms that may present include mental confusion, headaches, numbness, tingling, burning, vomiting, nausea and diarrhea.
