![]() However, when blood flow to the brain is interrupted, these neurons may die from a lack of oxygen.Īs a result, the victim may suffer from long-term disabilities such as paralysis, speech difficulties, and extreme sensitivity to light and sound. They communicate using chemicals called neurotransmitters, which are essential for neurological function. Neurons are specialized cells that communicate with each other to control all bodily functions. Stem cell transplantation for stroke aims to repair the damage done by the stroke by replacing neurons that have been lost. How Does Stem Cell Therapy Work for Stroke? This process is called transformation and reprogramming. In stem cell therapy, mesenchymal stem cells (these cells can renew and repair themselves) are systematically transferred during the treatment of the affected area and depending on how much damage has occurred. ![]() Once administered, they can transform into new neurons and repair damaged tissue. While stem cells can be extracted from several parts of the body like bone marrow, blood, or umbilical cord (which parents nowadays are preserving for in-future use), they can also be created artificially. This includes cells that are found in the brain - neurons. They are unspecialized cells that can transform into a variety of specialized cells. Stem cells are the biological building blocks of all living tissue they are also called regenerative cells that help the different damaged cells to regenerate into new and recovered cells. Strokes occur due to disturbance in the flow of blood due to either blockage in the artery or leaking or bursting of a blood vessel in the brain, which causes brain strokes. If you or someone you love has recently experienced a stroke, this article will answer some common questions about stem cell treatments for stroke treatment. Stem cell therapy remains an experimental treatment for stroke, but its potential is significant. In fact, of the over 800,000 people in the world who experience a stroke every year, about half are left with long-term effects.įortunately, recent advances in stem cell research may soon offer a solution for these debilitating conditions. People who have suffered from a stroke have limited options for recovery the devastating effects of a stroke leave patients struggling with disabilities physically related to smell, taste, or frequent memory gaps, and different chronic health issues. The risk of developing strokes increases as you grow older but currently, 10-15% of stroke cases are observed in young people. In both cases, more research to identify the best kind of stem cells to use, how and when to deliver them is necessary.With an average of at least one person worldwide suffering from a stroke every 45 seconds, it is clear that treatment options are needed. There are two main approaches: the first is to stimulate stem cells already in the body to repair damaged tissue and the second is to transplant specific stem cells directly to the site of injury in hopes that they will help stimulate repair. ![]() Since an incident of stroke cannot be predicted, the kind of research involving stem cells to treat stroke centres around repair after a stroke has occurred. Current treatments for stroke aim to restore the flow of blood to the brain, such as clot-busting enzymes, surgery and drugs for thinning blood, stopping clots and protecting neurons.Ĭurrently there are no Health Canada or FDA approved stem cell treatments available for stroke. There are many factors that can lead to a stroke, including high blood pressure, irregular heartbeat, diabetes and smoking, many of which can be managed through lifestyle choices. Regardless of the type of stroke, immediate medical attention is required to stem the tide of damage to the brain. A smaller percentage of strokes are caused by a rupture that causes bleeding in the brain. ![]() Most strokes are caused by a blood clot in the brain that interrupts the flow of blood and delivery of oxygen to brain tissue, causing minor to severe damage, even death. ![]()
