It is difficult to confirm / refute the diagnosis of mucopolysaccharidosis(MPS). Children with these disorders have poor physical growth, typical facial features and joint abnormalities. The diagnosis is suggested by X-rays. Generally MRI and EEG do not contribute towards making a diagnosis. A specific test of urine is also used as a screening test. Specific diagnosis requires enzyme testing. The drugs that you have been prescribed are meant for convulsions which are not a usual feature of MPS. At the same time it is important that your child is evaluated properly and a diagnosis made so that proper management plan be made. Also some of these disorders can be hereditary. So, probability of recurrence in subsequent children also has to be seen. I suggest your child be evaluated in detail at a bigger centre such as a Medical College.
