Parkinson’s disease is a progressive neurodegenerative disease that affects dopamine-producing neurons in the brain. The disease is characterized by a progressive loss of muscle control leading to bradykinesia (slow movement), rigidity, resting tremor, and postural instability. As symptoms worsen, it may be difficult to walk, talk, and perform simple tasks. Non-motor symptoms can include; anxiety, depression, psychosis, and dementia. Note: Despite all advances in stem cells research and the application of these therapies in many countries all over the world, stem cells therapies are not legally approved yet in San Diego, Los Angeles, Chicago, Dallas, New York, Jacksonville, Seattle, Houston, San Francisco, Salt Lake City, Miami, Beverly Hills and other US cities. However, stem cell treatments are legal in Costa Rica.
