For the new members seeking answers to this unusual rare disease, IMO, we must be careful not to give the wong impression, and also state the facts as we know them, and that is, that the cause and pathology of MMD is unknown. There may be several disorders/diseases in association with MM, but MM itself may not be the cause of them. There’s no doubt the associated problems may be relevant to MMD, but it is not proven that MMD itself causes them or that MMD itself affects other organs. The presentation of several disorders does however suggest a possible hereditary, congenital component. MM and it’s functional effects on the body are in study and research, so a long list of other possible underlying conditions could also be the cause as well, and not necessarily MM.
Sure, as Jenny and Nancy mentioned, heart defect, high blood pressure, as well as others, such as renal artery lesions, Down’s syndrome, etc may be associated with MMD, but they also could very well have a hereditary component to the cause as well, and not necessarily from MMD itself. MMD varies in each individual, and is a cerebrovascular disease.
