Welcome to HCM,
After going through your history at the age of 46 you got a small stroke
Ischemic Right parietal lobe
There is no clear cut risk factor apart from Oral contrceptive use ,I hope there is no neurological deficit at all.
A carotid Doppler study of both side if ano done already would be advisable.
Such episodes needs secondary prevention by Aspirin
325 mg which you are already taking.
According to neurology there are many possibilities but they do not seem to be of any significance in your case.
Regular physical exercise and keeping ideal body weight need to be emphasised.
Follow up with your Neurologist
Good luck to you.
