Recurrent Stroke. Of future stroke?

I had a stroke  1.5 years back. I got another stroke few days back. After my 2nd stroke dosage of Ecospirin has increased from 75 MG to 150 MG. I also have developed Vitamin B12 deficiency . Current Vitamin B12 level is 104 pg/mL. For that I take Benfomet Fortee. Apart from that I take Storvas 20 MG for Cholesterol. Right now , the cholesterol level is under control. I don't have diabetis, hypothyrodism or hypertension. Could you please evaluate my current CT scan report and give advise for a long term basis for better management and prevention of future stroke ? I don't have much problem now. I have little bit speech deficit and less energy to get involved in day to day work. But I remain really positive . Please give step by step advise. Please suggest if any more investigation is required to find out the root cause of recurrent stroke. And if everything is well and good with the management , don't forget to appreciate my positive attitude !
