Yes the main indicator of MS is brain and/or spinal lesions, even mild or unnoticeable attacks will leave them.

Depends what you mean by attack and what sort of MS your referring too. If it's a flare-up of existing symptoms then probably not, new Lhermittes syndrome then probably not as the lesion will be on the neck (not the brain) but for example new vertigo probably yes subject to confirmation with an MRI.
