The presence of demyelinating white matter lesions on brain MRIs at the time of presentation for optic neuritis is the strongest predictor in developing clinical diagnosis of MS. Almost half of patients with optic neuritis have white matter lesions consistent with multiple sclerosis.
For the same reason, the prodromal stage of MS (the unknown condition that causes the lesions) would not be considered as MS if it could be found. [ citation needed ] Sometimes the diagnosis must be retrospective , relying on gradual worsening of neurological signs/symptoms, due to the lack of understanding of the pathogenicity driving disease ...
Normally MS lesions are small ovoid lesions, less than 2 cm. long, oriented perpendicular to the long axis of the brain's ventricles [18] Often they are disposed surrounding a vein [19] Demyelinization by MS. The Klüver-Barrera colored tissue show a clear decoloration in the area of the lesion (Original scale 1:100)
These atypical lesion characteristics include a large intracranial lesion of size greater than 2.0 cm with a mass effect, edema and an open ring enhancement. A mass effect is the effect of a mass on its surroundings, for example, exerting pressure on the surrounding brain matter. Edema is the build-up of fluid within the brain tissue.
As MS lesions can affect any part of the CNS, a person with MS can have almost any neurological symptom or sign referable to it. Fatigue is one of the most common symptoms of MS. [27] [28] Roughly 65% of people with MS experience fatigue symptomatology, and of these, some 15–40% report fatigue as their most disabling MS symptom. [29]
Radiologically isolated syndrome (RIS) is a clinical situation in which a person has white matter lesions suggestive of multiple sclerosis (MS), as shown on an MRI scan that was done for reasons unrelated to MS symptoms. The nerve lesions in these people show dissemination in space with an otherwise normal neurological examination and without ...

Brain lesions associated with a clinically isolated syndrome may be indicative of several neurological diseases, like multiple sclerosis (MS) or neuromyelitis optica. In order for such a diagnosis , multiple sites in the central nervous system must present lesions, typically over multiple episodes, and for which no other diagnosis is likely.
