This invention pertains to nine miRNAs that are differentially expressed between patients with good and poor stroke recovery. By analyzing and comparing a plasma sample taken from a patient having a normal miRNA profile, healthcare providers can determine if the subject’s miRNA profile is altered compared to a normal miRNA profile. An alteration of the subject’s miRNA profile is indicative of increased risk of poor recovery after suffering a stroke. They can use this information to further determine the effectiveness of rehabilitation therapies.
- Prognosis in stroke recovery
- Timing rehabilitation therapies as well as determining their effectiveness
- Potentially identifying patients who would be good candidates for additional therapies
- MicroRNAs, are small enough to cross the blood brain barrier and are protected from degradation in the peripheral blood by traveling in exosomes
- Convenient and inexpensive compared to MRIs, which are also less predictive
Stage of Development
Refining microRNA biomarker panel through testing on a larger sample of patients. Currently two studies in process, one with 80 participants and the other with 50, to further elucidate biomarker effectiveness.
