Outside trials, evidence does not support it. Unproven therapy carries surgical and immune risks and yields modest, temporary change at best. Established medications are proven, adjustable and far cheaper; deep-brain stimulation, though invasive and costly, is approved with sustained benefit for selected patients. Pursue stem cells only within a formal trial, with independent supervision and realistic, research-oriented expectations.
Parkinson's disease results from progressive loss of dopamine-producing neurons in the substantia nigra. Stem-cell research pursues two complementary routes: neurogenic cells differentiated toward dopamine neurons are studied to replace lost cells and restore dopamine signalling, while placental mesenchymal stem cells are explored for neuroprotection — slowing degeneration through anti-inflammatory and growth-factor secretion. Preclinical evidence suggests dopamine-releasing cells can reinnervate the striatum and that trophic factors may delay neuronal death. Key challenges are achieving cell survival, integration and functional restoration in a degenerating brain. Most trials are early-phase, with modest motor changes reported.
