MS is associated with classic lesions and symptoms of optic neurtis, or weakness or sensory changes in the extremities is that occurs more than once and tends to follow a course of waxing and waning is fairly easy to diagnose. Many patient with MS signs and symptoms don't have classic lesions or symptoms. It's the cause of the lesions that is in question. In this regard, whiplash can cause violent venous blood and CSF inversion flows into the supratentorial, periventricular and perivenular spaces that can result in classic lesions. The design of the skull, especially the posterior fossa affects the force of the inversion flows. Some designs are better at modifying waves like a seawall that is sloped versus straight. Whiplash can also cause traumatic brain injuries and intracranial dura tissue injuries. The intracranial dura mater forms critical tunnels in the brain that can be damaged. Whiplash can also tear muscles and connective tissues in the upper cervical and lower spine that can create tension on the cord and sometime displacement (ectopia) of the brain in the vault. The latest MRIs are showing the tears. In any case, if the whiplash results in the classic surpatentorial, periventricular and pervivenular lesions, as well as optic neurits or weakness or sensory changes in the extremities in more that one occurance that follows a course of waxing and waning, then it's clearly fits the classic definition of MS regardless of whether or not it fits the current theory regarding the cause. The signs and symptoms are all that matters. The cause of the MS is the trauma. One of the problems it that upper cervical injuries can affect blood and CSF flow, which can cause many problems. It also cause joint instabilities and degeneration. The problem with MS is that it initiates neurodegenerative conditons. The lesions aren't the problem. They are usually permanent and can't be fixed. They are just a sign of the problem. It's the underlying cause of the ongoing degenerative conditions that needs to be addressed.
