Stem cell therapy in neurological disorders: promises and concerns

Abstract

Self-neuronal regeneration is often limited or nonexistent after neuronal cell damage, making new technologies necessary for treating neurological damage. Although the brain can partially compensate by increasing its plasticity, these compensatory mechanisms can never fully restore the pre-damage state. Analysis of the literature regarding stem cell therapy in case of neurological disorders. Stem cells have shown promise for treating various neurological disorders and disabilities due to their regenerative capacity. Transplanting or administration of different types of stem cells has yielded promising results in animal models and early clinical trials. However, concerns remain regarding their implementation. The type of stem cell used, the optimal method and route of administration, the number of stem cells administered, preconditioning, and the injection schedule all need to be determined. Additionally, the long-term safety of stem cell treatment and the recipient’s age requires further investigation. Despite these concerns, stem cell therapy holds tremendous promise for treating neurological disorders, and continued research and well-designed studies will be crucial for unlocking its full potential.
