Even though there is no age criteria for the diagnosis of MS, a stipulation of the criteria warns that the physician needs to rule out alternative diagnoses that could mimic MS. That is not to say that every reportable mimic needs to be tested for (that would be quite expensive and submit many patients to unnecessary testing), but your personal story and neurologic examination can quickly rule out many possibilities.
It is also important to remember that as we age, all are susceptible to common health problems including high blood pressure, diabetes, high cholesterol, vascular disease, etc. Patients with MS are no different, and as you may imagine, the diagnosis later in life can be more difficult to tease apart from problems of older age. If there is ever a question about a diagnosis, it is completely acceptable to seek a second opinion from an independent MS specialist.
