The study will follow you for one year to see if the medication helps your brain recover better than standard care alone.

After a stroke, many people experience problems with memory and thinking skills that can affect their daily lives. This medication exists to see whether this herbal supplement can help the brain heal and restore these abilities better than current standard treatments alone.

Do you qualify?

You likely qualify if…

you are 55 years old or older
you had a minor stroke 7 to 14 days before enrolling (confirmed by MRI scan)
you now have noticeable memory or thinking problems since the stroke
you speak Chinese well enough to answer questions and complete tests
you did not have thinking or memory problems before your stroke

You likely don't qualify if…

you have severe language or speech problems, vision loss, or hearing loss that would prevent you from participating in tests
you had thinking or memory problems before your stroke, or you have been diagnosed with dementia
you are taking blood thinners or medications that prevent clots (certain heart conditions require these)
you have other serious brain conditions like Parkinson's disease, epilepsy, brain tumors, or HIV-related brain disease
you have a known allergy to ginkgo biloba or are currently taking traditional Chinese medicines

What participation looks like

You would be randomly assigned to either take the ginkgo biloba extract (240 mg per day in three doses) plus your regular stroke treatments, or to continue with standard care alone. Over 52 weeks, you would visit the hospital at scheduled times for follow-up appointments where doctors check your recovery, test your memory and thinking, and monitor how you're doing. The study team will assess your progress and watch for any side effects throughout the year.
