What is a Stroke?

Stroke and Stem Cell Therapy


A stroke (Cerebrovascular Accident or CVA), is the rapid loss of brain function due to the blood supply to the brain being disturbed. This can be from ischemia from the lack of blood flow or from a blockage known as Thrombosis, an Arterial Embolism, or a Haemorrhage where blood is leaking out or inside the brain.

The affected area of the brain is unable to function correctly and may result in an inability to move especially in one or more limbs on one side of the body. Stroke can also cause an inability to understand speech or speak or see properly. 

A stroke is a medical emergency that needs immediate medical attention. Stroke can cause permanent neurological damage and ongoing complications, and death. It is the a leading cause of adult disability in the around the world.

Risk factors for stroke include ederly people,  high blood pressure (hypertension), a previous stroke or from a transient ischemic attack (TIA).

Other related risk conditions include diabetes, high cholesterol, cigarette smoking and atrial fibrillation. High blood pressure is the most important modifiable risk factor of stroke.

A silent stroke is a stroke that does not have any outward symptoms, and the patient is typically unaware they have suffered a stroke. A silent stroke still causes damage to the brain, and places the person at risk for both transient ischemic attack and a major stroke occuring in the future.

People who have suffered a major stroke are at risk of having silent strokes as well.Stem Cell Treatment for Stroke

Stroke is a common, serious, and disabling global health-care problem, and rehabilitation is a major part of patient care. There is evidence to support rehabilitation in well coordinated multidisciplinary stroke units or through provision of early supported provision of discharge teams. Potentially beneficial treatment options for motor recovery of the arm include constraint-induced movement therapy and robotics.

Promising interventions that could be beneficial to improve aspects of gait include fitness training, high-intensity therapy, and repetitive-task training. Repetitive-task training might also improve transfer functions. Occupational therapy can improve activities of daily living; however, information about the clinical effect of various strategies of cognitive rehabilitation and strategies for aphasia and dysarthria is scarce. Several large trials of rehabilitation practice and of novel therapies (eg, stem-cell therapy, repetitive transcranial magnetic stimulation, virtual reality, robotic therapies, and drug augmentation) are underway to inform future practice.

Related Articles Intravenous Bone Marrow Mononuclear Cells for Acute Ischemic Stroke: Safety, Feasibility, and Effect Size from a Phase I Clinical Trial. Stem Cells. 2019 Sep 17;: Authors: Vahidy FS, Haque ME, Rahbar MH, Zhu H, Rowan P, Aisiku IP, Lee DA, Juneja HS, Alderman S, Barreto AD, Suarez JI, Bambhroliya A, Hasan KM, Kassam MR, Aronowski J, Gee A, Cox CS, Grotta JC, Savitz SI Abstract Cellular therapy is a promising investigational modality to enhance poststroke recovery. We conducted a single-arm, phase I clinical trial to determine the safety and feasibility of intravenous (IV) administration of autologous bone marrow mononuclear cells (MNCs) after acute ischemic stroke (AIS). Patients with moderate severity of AIS underwent bone marrow harvest followed by IV reinfusion of MNCs within 24-72 hours of onset. A target dose of 10 million cells per kilogram was chosen based on preclinical data. Patients were followed up daily during hospitalization and at 1, 3, 6, 12, and 24 months for incidence of adverse events using laboratory, clinical (12 months), and radiological (24 months) parameters. The trial was powered to detect severe adverse events (SAEs) with incidences of at least 10% and planned to enroll 30 patients. Primary outcomes were study-related SAEs and the proportion of patients successfully completing study intervention. A propensity score-based matched control group was used for the estimation of effect size (ES) for day-90 modified Rankin score (mRS). There were no study-related SAEs and, based on a futility analysis, enrolment was stopped after 25 patients. All patients successfully completed study intervention and most received the target dose. Secondary analysis estimated the ES to be a reduction of 1 point (95% confidence interval: 0.33-1.67) in median day-90 mRS for treated patients as compared with the matched control group. Bone marrow harvest and infusion of MNCs is safe and feasible in patients with AIS. The estimated ES is helpful in designing future randomized controlled trials. Stem Cells 2019.
