Parkinson’s can cause a wide range of symptoms. The disorder is sometimes known to be caused by a combination of genetic and environmental factors. While it affects people differently, low dopamine activity has been found to be an important cause behind the symptoms.
Our brain cells (called neurons) release chemical messengers called neurotransmitters. One of them is dopamine. This chemical is associated with many significant functions of the brain including movement, motivation, mood, attention and others.
