Stroke Recovery Rate

After a stroke, the next few weeks and months are associated with a gradul improvement and recovery of cognitive capacities to near pre-stroke levels. Some supplements have been noted to accelerate this recovery or help survivors of stroke.

Human Effect Matrix

The Human Effect Matrix looks at human studies (it excludes animal and in vitro studies) to tell you what supplements affect stroke recovery rate
Grade Level of Evidence
Robust research conducted with repeated double-blind clinical trials
Multiple studies where at least two are double-blind and placebo controlled
Single double-blind study or multiple cohort studies
Uncontrolled or observational studies only
Level of Evidence
? The amount of high quality evidence. The more evidence, the more we can trust the results.
Outcome Magnitude of effect
? The direction and size of the supplement's impact on each outcome. Some supplements can have an increasing effect, others have a decreasing effect, and others have no effect.
Consistency of research results
? Scientific research does not always agree. HIGH or VERY HIGH means that most of the scientific research agrees.
Notes
grade-b
Ginkgo biloba
- - See study
Although there is some scattered evidence to support the role of ginkgo in stroke recovery rates, the best evidence currently available does not find a significant therapeutic benefit.
grade-c
Astragalus membranaceus
Minor - See study
Not remarkably effective, but does confer some protective and cognitive promoting effects following acute stroke.
grade-c
Phenylpiracetam
Minor - See study
Symptoms (cognitive and physical) seen after a stroke appear to be more rapidly recovered with daily usage of phenylpiracetam than with placebo

All comparative evidence is now gathered in our ​A-to-Z Supplement Reference.

The evidence for each separate supplement is still freely available ​here.
