YES guest, CORRECT......... 
It's MS and th emost iformative ancillary test wud be MRI......
Multiple lesions disseminated in time &space are typical of MS. With MRI, the multifocal areas of demyelination shud be apparent.
Her visual loss xplained by optic neuritis
Bladder problems----demyelination of CS tract fibres.
Pos babinski, focal dysmetria,apparent dysarthria......multifocal CNS lesion.
