Patient Q&A Section

Can mps iii a be cured?

"There is no evidence to suggest that mps iii a can be cured. The available studies suggest that the use of this medicine is harmful. Mps iii a should not be prescribed off-label. There are no trials or meta-analyses that suggest that the use of methylphenidate in children under 12 years old lead to adverse effects and adverse reactions such as suicidal ideation, psychosis, tic disorders, and neurocognitive problems. While the risks and harms of methylphenidate in children are well documented, the evidence does not support the claims of health care providers who administer the drug to children. Physicians can reassure patients and parents that methylphenidate cannot be cured; only the severity of the symptoms will decrease with treatment." - Anonymous Online Contributor

Does mps iii a run in families?

"Recent findings were obtained by a multidisciplinary collaboration with the expertise of two medical schools and by the collaborative cooperation of several units. Recent findings allows us to estimate that the disease penetrance level is higher in the families in which the subjects have the same MPS IIIa genotype than in the other families. The study also reveals that the homozygous MPS IIIa carriers have significantly impaired hepatic LSM function on magnetic resonance imaging." - Anonymous Online Contributor
