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.

Mol Neurobiol. 2017 Jul 24;: Authors: Kim C, Park JM, Kong T, Lee S, Seo KW, Choi Y, Song YS, Moon J Abstract Traumatic brain injury (TBI), a complicated form of brain damage, is a major cause of mortality in adults. Following mechanical and structural primary insults, a battery of secondary insults, including neurotransmitter-mediated cytotoxicity, dysregulation of calcium and macromolecule homeostasis, and increased oxidative stress, exacerbate brain injury and functional deficits. Although stem cell therapy is considered to be an alternative treatment for brain injuries, such as TBI and stroke, many obstacles remain. In particular, the time window for TBI treatment with either drugs or stem cells and their efficacy is still vague. Human placenta-derived mesenchymal stem cells (hpMSCs) have received extensive attention in stem cell therapy because they can be acquired in large numbers without ethical issues and because of their immune-modulating capacity and effectiveness in several diseases, such as Alzheimer's disease and stroke. Here, we tested the feasibility of hpMSCs for TBI treatment with an animal model and attempted to identify appropriate time points for cell treatments. Double injections at 4 and 24 h post-injury significantly reduced the infarct size and suppressed astrocyte and microglial activation around the injury. With reduced damage, double-injected mice showed enhanced anti-inflammatory- and TNF-α receptor 2 (TNFR2)-associated survival signals and suppressed pro-inflammatory and oxidative responses. In addition, double-treated TBI mice displayed restored sensory motor functions and reduced neurotoxic Aβ42 plaque formation around the damaged areas. In this study, we showed the extended therapeutic potentials of hpMSCs and concluded that treatment within an appropriate time window is critical for TBI recovery.
