T:Question regarding my brain MRI results	

>Q:I had a <diagnostic_test> done because I have some lesions on my brain that were noticed <time_period> ago on an <diagnostic_test> (done because of some neuro issues). 
 I am <age> old now. 
 Anyhow,  my <diagnostic_test> has been stable with regard to the lesions,  however,  I just received a copy of my <diagnostic_test that was done <day> and I don't understand what it could mean. 
 It says: FINDINGS: Within the supratentorial white matter,  there are approximately <num> areas of abnormal T2/FLAIR white matter hyperintensity. 
 The most conspicuous of these lesions is in the left frontal operculum. 
 There is relative sparing of the temporal lobes. 
 There is no abnormal enhancement on postcontrast imaging. 
 No new lesions compared to the prior study. 
 No mass effect,  hydrocephalus or evidence for hemorrhage. 
 No reduced diffusion within the brain or skull. 
 Normal marrow signal intensity within the skull base,  calvarium and facial skeleton. 
 IMPRESSION: Redemonstration of multiple supratentorial areas of nonspecific but abnormal white matter signal abnormality,  unchanged compared to the prior study from <date>. 
 END OF IMPRESSION Can someone tell me this means. 
 Specifically,  the RELATIVE SPARING OF THE TEMPORAL LOBES? I am so very afraid that I might have early onset of dementia or Alzheimer's or something. 
 Unfortunately,  I don't have a <professional_practitioner> appointment until <date> and in the meantime,  I'm really scared. 
 Any input would greatly appreciated.
