Understanding All Stages of Parkinson’s Disease

Parkinson’s disease is commonly known as PD and is a progressive and a chronic movement disorder. All the symptoms continue and worsen over a period. In this disease, there is the death of the nerve cells which are vital, and all this happens in the brain. These nerve cells are the neurons. Parkinson affects the neurons Substantia Nigra area or part of the brain. The Dopamine levels in the brain, which help to send messages to the brain from the rest of the body gradually decrease, this, in turn, leaves the person feeling helpless as the movement is not controlled or is erratic.

The cause of Parkinson Disease is unknown, and generally, there is no real cure apart from some surgeries and medications that are used to reduce the effect of the disease. The causes are divided into Genetic Factors and Environmental Factors. There is always a risk to develop Parkinson if someone in your blood relations has the same issue, the predisposition increases. Environmental Factors could be some brain injuries, environmental toxins, manganese, water, an unhealthy lifestyle, pesticides; prolonged exposure to occupational chemicals is also a cause of developing this disease. The symptoms of Parkinson disease vary from person to person. A lot of symptoms are to do with the motor skills. A person who has Parkinson will experience slowness of movement which is called bradykinesia, tremors of jaws, hands, legs, arms, face, stiffness or rigidity of limbs and trunk; there is also a lot of impaired balance and coordination in the body movements which is commonly known as postural instability.

A lot of specialists say that in Parkinson Disease there is a considerable amount of loss of cells from the other parts of the brain as well which affects the senses as well, like the olfactory area and even sleep regulation is very erratic. The intestines present in our body also have dopamine, so during Parkinson, a person experiences intestinal issues like gastrointestinal problems.

The symptoms of Parkinson Disease are classified in three dimensions that are: Primary Motor symptoms, Secondary Motor Symptoms and Nonmotor Symptoms. Secondary Symptoms including the freezing of the body or parts of body, rigidity, shrinkage of handwriting, which is also known as micrographia. In Micrographia, face expressions also weaken, and the person might have a mask like face most of the time, the person suffering from Parkinson might also experience unwanted body accelerations like moving too quick or too slow. A lot of people who have Parkinson will even have stooped posture and difficulty in swallowing food.
