Study Groups
Review each arm or cohort in the study, along with the interventions and objectives associated with them.
Placebo plus standard of care
Participants will start taking either memantine or placebo within 24 hours after baseline testing and randomization is completed, but no later than day 8 post-symptom onset. Participants will titrate up on the dose of placebo until taking twice daily. Participants will continue for 90 days with placebo. Continue with standard of care for other treatment of stroke.
Placebo (for memantine)
Placebo to be capsuled to look identical to active drug (memantine)
Memantine plus standard of care
Participants will start taking either memantine or placebo within 24 hours after baseline testing and randomization is completed, but no later than day 8 post-symptom onset. Participants will use a titration schedule starting at 7mg daily for 1 week, increasing by 7mg (1 capsule) per week until at a goal dose of 28mg daily (goal dose) as recommend by the manufacturer. Participants will continue memantine for 90 days. Continue with standard care for stroke.
Memantine XR
The active drug will be encapsulated by the University of Utah Research Pharmacy to maintain blinding.

Eligibility Criteria
Check the participation requirements, including inclusion and exclusion rules, age limits, and whether healthy volunteers are accepted.
Inclusion Criteria
2. Randomization between 3 days-8 weeks days of stroke symptom onset
3. Arm weakness severe enough to warrant inpatient or outpatient occupational therapies
4. Able to voluntarily move affected UE
5. Living independently prior to their stroke
6. Image-confirmed ischemic stroke (MRI or CT)
7. Supratentorial location of stroke

9. Ability to swallow pills
Exclusion Criteria
2. Infratentorial location of stroke (brainstem or cerebellum)
3. NIH Stroke Scale \>20 at the time of randomization

5. Pre or post-stroke use of memantine or amantadine
6. Contraindications to taking memantine XR in pill form
7. History of prior clinical stroke with residual symptoms on the same side as the current symptoms that would interfere with outcomes of this study
8. Documented severe renal impairment (CrCl \< 30 ml/min) Blood tests will be performed prior to study procedures that will ensure patients do not have renal impairment if not done as part of clinical care.
9. Moribund or not expected to live 6 months
10. Severe cognitive deficits or pre-morbid function causing inaccurate neurologic assessment or inability to complete the initial assessment
11. Comorbid neurologic disease that would interfere with the results including but not limited to Multiple Sclerosis, neurodegenerative diseases, spinal cord disease, and central nervous system cancer.
12. Documented severe hepatic impairment (Child-Pugh score \> 6) or severe hepatic disease (hepatitis)
13. Patients who are pregnant or breast feeding
