white matter foci in subcortical white matter

I had an mri done in june and they said I had several nonspecific white matter foci in the subcortical white matter, although these are not typical of the demyelinating plaques due to ms, they are somewhat prominent due to my age of 40, I really would like to hear an answer back, I am getting frustrated.

Hi
Welcome to the MedHelp forum!
White spots on MRI are seen in MS, microvascular disease (arteriosclerosis), some types of headaches, Alzhiemer’s disease, old age and even due to TBI. It is difficult to differentiate the white spots due to one disease from the white spots due to another. Patient history and other parameters are taken into consideration and co related with the MRI picture. If you have any symptoms then discuss this with a neurologist. Take care!

I WENT TO THE ER BECAUSE MY SPEECH WAS SLURRED.. THE FINDINF OR NOTE ON MY MRI WAS FOCI OF INCREASED SIGNAL IN DEEP PERVENTRICULAR WHITE MATTER CONCERNING FOR CHANGES OF DEMYELINATING DISEASE PROCESS AND MULTIPLE SCLEROSIS. DON'T REALLY UNDERSTAND CAUSE THEY ALSO DID A SPINAL TAP AND TESTES CAME BACK NEGATIVE FOR MS. BUT SOME OF MY BLOOD TEST FOR ANA SCREEN CAME BACK POSITIVE FOR LUPUS. MY BODY BEEN VERY WEEK AND ALOT OF BURNING IN THE IN SIGN OF MY BODY. SO CONFUSED TOO.
