Primary Progressive Multiple Sclerosis (PPMS) is a form of multiple sclerosis characterized by a gradual worsening of neurological function over time. Unlike relapsing-remitting MS, PPMS typically does not have distinct periods of remission, leading to progressive disability.
Current Challenges in PPMS Treatment
Treating PPMS poses significant challenges due to its progressive nature and limited efficacy of existing therapies. Conventional treatments focus on symptom management and slowing disease progression but do not offer a cure or halt the degenerative process effectively.
Significance of Stem Cell Therapy in PPMS Management
Stem cell therapy has emerged as a promising approach for PPMS due to its potential to address the underlying mechanisms of neurodegeneration and promote tissue repair. By harnessing the regenerative properties of stem cells, researchers aim to develop novel treatments to modify the course of the disease.
