Parkinson's Disease: Parkinson's disease is a progressive disorder of the nervous system that affects your movement. It develops gradually, sometimes starting with a barely noticeable tremor in just one hand. But while tremor may be the most well-known sign of Parkinson's disease, the disorder also commonly causes stiffness or slowing of movement.
In the early stages of Parkinson's disease, your face may show little or no expression or your arms may not swing when you walk. Your speech may become soft or slurred. Parkinson's disease symptoms worsen as your condition progresses over time. Although Parkinson's disease cannot be cured, medications may improve your symptoms.
A person with Parkinson’s disease can also experience a wide range of other physical and psychological symptoms, including depression, constipation, problems sleeping (insomnia), loss of sense of smell (anosmia) and memory problems.
See your doctor if you are concerned that you may have symptoms of Parkinson's disease.
What is Dopamine?
Dopamine is a neurotransmitter that helps control the brain's reward and pleasure centers. Dopamine also helps regulate movement and emotional responses, and it enables us not only to see rewards, but to take action to move toward them. Dopamine deficiency results in Parkinson's Disease, and people with low dopamine activity may be more prone to addiction. The presence of a certain kind of dopamine receptor is also associated with sensation-seeking people, more commonly known as "risk takers." Source:
