<unk>  dysplasia  must be differentiated from other diseases that present  clinical features of multisystem involvement, hypertension, aneurysm, and dissection, such as atherosclerotic vascular disease, vasculitis, and Ehlers-Danlos Type IV.
There is a significant delay in diagnosis from the first onset of clinical symptoms/signs of 4.4 years in men and 4.1 years in women. There are several possible reasons for such a delay, including the possibility that FMD is not considered in the differential diagnosis of a patient’s symptoms because of under-recognition of this disorder, as well as  the mistaken belief that FMD is predominately a rare disease of young patients, and the fact that many of the signs and symptoms of FMD are nonspecific, such as dizziness, tinnitus, and headaches.
