Melody started showing symptoms a few days after having her joint measles, mumps and rubella (MMR) vaccination in July.
She became unsteady on her feet, then started falling over and then was admitted to hospital.
She has been in Leeds General Infirmary since, though returns home to Belle Isle at weekends. Doctors admit they do not know what has caused her disabilities.
