Hi,
Thank you for posting your query.
I would like to reassure you that the 
MRI brain findings in your case do not represent any serious abnormalities. 
Ischemic 
gliosis refers to old areas of brain affected with lack of blood flow. 
Ischemia means lack of blood flow to brain, and is suggestive of small brain 
stroke in your case. Gliosis refers to old healed area of brain stroke. 
I hope my answer helps. Please get back if you have any follow up queries or if you require any additional information.
Wishing you good health,
Dr Sudhir Kumar MD (Internal Medicine), DM (Neurology)
