Parkinson’s disease is the world’s fastest growing brain disease, affecting over 10 million people around the world and over 1 million people in the United States. It is marked by the death of dopamine-producing cells in the substantia nigra region of the brain. Dopamine is important because it helps transmit messages between nerve cells. As these brain cells die, less dopamine is produced. This cell death leads to various symptoms including stiffness, slowed movement, tremors, and difficulty with coordination and balance.
We don’t know exactly what causes Parkinson’s disease. Researchers have found that many different factors are involved, including genetics and the environment.
Common symptoms include tremors, slowed movements, rigidity, and difficulty speaking. Parkinson’s disease may also impair cognition and memory.
