[|Human|] I just had an MRI which showed "mild chronic small vessel ischemic changes in the periventricular and subcortical white matter of both cerebral hemispheres".  I am 47, height/weight proportionate, low blood pressure and heart rate, lab work is normal.  I exercise regularly.  Symptoms are left facial numbness, headache and pain/constriction in left hand, arm.Is this a normal finding for someone may age.  Do the MRI findings explain my symptoms?
[|AI|]  Hi, the symptoms left facial numbness, headache, pain and constriction of the left hand and arm.  The M.R.I. showing the ischemic changes in both the hemispheres, so the symptoms may not be solely due to the M.R.I. changes, or to some extent related due to the deeper changes. But definitely not related to the age.  I advise you to consult a neurologist for diagnosis, as he is authorized to look after and have full knowledge about these cases. Thank you.
