Background: A neurological condition known as demyelinating illness causes damage to the myelin sheath, which protects nerve fibers, optic nerves, and the spinal cord. The damage weakens the conduction of transmission signals in affected nerves. This reduction cause deficiency in cognition, movement, sensation, or other neurological functions in which the nerves are involved. Here we are presenting a case of a 5-year-old male child who was brought by his parents to the emergency department with the chief complaints of difficulty in swallowing, slurred speech, weakness, stiffness of muscle, fever and cough, pain, and loss of coordination. He has a history of hospitalization for pneumonia at the age of one year. Physical examination shows weakness and dullness along with localized tenderness, muscle spasms, difficulty in movements, and slurring of speech. He has undergone a blood test, Magnetic resonance imaging (MRI). And then started on immunosuppressive therapy.
