The most common form of parkinsonism is Parkinson's disease. The result of the loss of dopamine-producing brain cells is the primary symptoms mentioned above. Parkinson's disease is called primary parkinsonism or idiopathic Parkinson's disease. A term that mentions a disorder for which no cause has been found is described as an idiopathic condition. The cause of Parkinson's disease is known or suspected in other forms of Parkinson's disease.

Therefore insufficient amount of dopamine present in the brain. Due to the lower amount of dopamine present in the brain, a person's ability to regulate body movements, body and emotions. There are serious complications due to the disease. Complications of Parkinson's disease are ranked as the 14th leading cause of death in the United States by the Centers for Disease Control and Prevention (CDC). There is no total cure for Parkinson's disease. Dopamine is normally produced by brain cells known as neurons in the human brain. The substantia nigra is a particular area of ​​the brain where these neurons are concentrated. Dopamine is a chemical that transmits messages between the substantia nigra and other parts of the brain to control movements of the human body. Smooth and coordinated muscle movements in the human body are due to dopamine. The motor symptoms of Parkinson's disease appear when approximately 60 to 80 percent of the dopamine-producing cells are damaged and do not produce enough dopamine. This process of deterioration of brain cells is called neurodegeneration. The enteric nervous system, the medulla and In particular, the olfactory bulb, which controls the sense of smell, involves the first signs of Parkinson's disease, according to the current theory called Braak's hypothesis. The theory explains that over the years the disease only affects the substantia nigra and the cortex. To classify the degree of pathology in Parkinson's disease and Alzheimer's disease, Braak staging refers to two methods. By performing an autopsy of the brain, the clinical diagnosis of these diseases is obtained. To detect Parkinson's disease as early as possible, researchers work primarily on these "non-motor" symptoms. The person may hear their doctor refer to their Hoehn and Yahr stage. This scale, first introduced in 1967, is a simple assessment tool used by doctors as a means of generally describing how motor symptoms progress in Parkinson's. It takes into account factors other than motor symptoms, including mental functioning, mood and social interaction. Please note: this is just an example.
