A deficiency of dopamine is responsible for the signs and symptoms of Parkinson's disease.
Parkinson's disease is characterized by gradual degeneration of neurons in a section of the brain. In normal conditions, these neurons release a chemical substance known as dopamine which is important for the brain.
Dopamine is a neurotransmitter which facilitates communication amongst different parts of the brain that is responsible for smooth muscle activity and proper nerve operation.
Parkinson’s disease is a disorder generally associated with uncontrollable movements like tremors, rigidity as well as problems linked with maintaining body balance and coordination. Symptoms generally develop slowly and intensify over the period.
People may experience trouble in walking and talking with the advancement of the disease. The patients may also exhibit mental as well as behavioral alterations, sleep trouble, depression, memory problems and lethargy.
