Parkinson's disease is a chronic neurological condition that causes a wide variety of symptoms and makes movement difficult. It affects each person differently and progresses at a different rate. Treatment requires a multidisciplinary approach...
Of all the rich chemicals in the amazing organ we call the brain, dopamine plays one of the most dramatic roles. Too little dopamine can cause slowed movement, apathy and lack of motivation. Too much dopamine is associated with schizophrenia and...
Dopamine is a chemical that is created by the neurons in your brain and acts as a transmitter between nerve cells. Most of the neurons that create dopamine come from the part of your brain called the substantia nigra. Dopamine is necessary for...
Chemical messengers in the body exert their effects by binding to receptors, much like a key fits in a lock to open a door. The nerve messenger dopamine mediates multiple important effects in the brain, and its activity is tightly regulated...
