Our brain runs on electricity and chemicals. If there is too much or too little of a chemical in your brain, it causes a disease. Parkinson’s disease is caused by the reduction of a chemical called “Dopamine” in our brain.
Dopamine is produced in the back of our brain, in a part called the “Mid-Brain”. It is then transported forwards and is widely distributed throughout the entire brain. It fires up the movement centers of our brain, and helps them communicate better with one another.
In Parkinson’s disease the cells in the midbrain producing Dopamine gradually die. No one quite understands why this happens. The net effect is that the movement centers of the brain don’t communicate well with one another, and this produces the various symptoms of Parkinson’s Disease.
Deficiency of a chemical called dopamine is the basic problem in Parkinson’s disease.
