Parkinson’s disease is one of many diseases like Alzheimer’s with an unknown cause. However, scientists can identify the cells and areas of the brain which the disease targets. Practitioners use stem cell treatment to re-grow Dopamine-producing nerve cells in patients with Parkinson’s. If a single well-defined type of cell is affected, Parkinson’s is likely treated by replacing unhealthy neurons with new ones.

There is a strong link between the level of dopamine in the brain and the onset of Parkinson’s disease, which is essentially a case of dying neurons in the substantia nigra part of the brain that subsequently results to loss of motor functions. In a few different studies which tried to assess the treatment potential of stem cells therapy against the said disease, an exciting finding was found—the stem cell treatment induces dopamine functions in the brain (Kim et al., 2002; Rodriguez-Gomez et al., 2007).

There are some medical doctors and scientists who already use stem cell treatment for Alzheimer’s disease and claim that the treatment is successful. Although there is still no approved and carefully regulated process for administering treatments, hospitals and clinics which receive the green light from the government’s health sector utilize stem cell treatment for patients with Alzheimer’s. Currently, researchers are still conducting clinical trials for Alzheimer’s disease to find methods with consistent success in the future.

The backbone is a special part of the body in that it not only serves as a frame that enables us to perform motor functions in tandem with the body’s tissues, it also houses one of the body’s major nerve. The idea applies not just to humans, but to all vertebrates, in general. In an interesting study which made use of an animal subject with spinal cord injury saw that stem cells treatment has the potency to treat the condition (McDonald et al, 1999). A different study by Keirstad et al (2005) also supported the same claim.

During clinical trials, stem cells contribute to spinal cord regeneration by renewing the neurons that died because of the injury, reforming myelin and acting as a support column across the injury, protecting cells from damage by the release of growth factors and bonding with free radicals, and relaxing the inflammation from the injury."
