What does it mean that your brain is older than your age?

[BernadetteAnn]

Hi - I am a 48 and have been experiencing nausea and feeling lightheaded. I have had some lumbar problems as well. I might also mention that is have had 2 episodes of shingles as well previously. Not sure if this is related.

My GP referred me to a hearing specialist, but my hearing was fine. She then referred me to an ENT who then ordered to have an MRI, trying to see if I might have MS.

The finding of the MRI from the radiologists were as follows: few nonspecific T2 hyperintense foci are seen scattered in the supratentorial white matter.

I have no clue to what this means. I am scheduled to see a Nuerologist next week.

When I asked the ENT what she thought about what brought on this condition she said this:  best guess is that these are scattered areas that have healed from past injuries ( trauma, decreased blood flow, other inflammation). So your brain would do some rewiring/ rerouting if these areas healed with less function.

Should I be worried? What can I expect from the nuerologist? Any insight would be appreciated. Thank you!
