“Parkinson’s disease (PD) is a neurodegenerative disorder that affects predominately dopamine-producing (“dopaminergic”) neurons in a specific area of the brain called substantia nigra.  A new study confirms that men are more likely to have Parkinson’s than women and that the number of those diagnosed with PD increases with age, regardless of sex.  Symptoms generally develop slowly over years. The progression of symptoms is often a bit different from one person to another due to the diversity of the disease.”
