Dopamine is a type of monoamine neurotransmitter. It’s made in your brain and acts as a chemical messenger, communicating messages between nerve cells in your brain and your brain and the rest of your body. Dopamine also acts as a hormone. Dopamine, epinephrine and norepinephrine are the main catecholamines (a label based on having part of the same...
Dopamine plays a role in many body functions. As a neurotransmitter, dopamine is involved in: 1. Movement. 2. Memory. 3. Pleasurable reward and motivation. 4. Behavior and cognition. 5. Attention. 6.

Many diseases are associated with high or low levels of dopamine. There’s still much to be learned. For example, does a high or low level of dopamine cause disease or does disease cause a change in the dopamine level? Can the answer be both? Adding to the confusion is that the function of a single neurotransmitter like dopamine can’t be viewed in i...
Dopamine agonistsare drugs that mimic the natural neurotransmitter dopamine. Dopamine agonists bind to and activate the dopamine receptors on nerve cells in your brain, causing nerve cells to react in the same way as they would to natural dopamine. Dopamine agonists are used to treat Parkinson’s disease, depression, restless legs syndrome, attentio...
Dopamine antagonistsare drugs that bind to and block dopamine receptors (on the receiving nerve cell) in your brain. This means they block or stop dopamine from being received by the next nerve cell. Many antipsychotic drugs are dopamine antagonists. Dopamine antagonists are used to treat schizophrenia, bipolar disorder, nausea and vomiting, Exampl...
Dopamine reuptake inhibitors are drugs that prevent dopamine from re-entering and being reabsorbed by the nerve cell that released it. This makes more dopamine available to more neurons in your brain. Dopamine reuptake inhibitors are used to treat depression and narcolepsy, and to overcome addictions such as smoking, overeating and binge eating. Ex...
Levodopa is used to treat Parkinson’s disease. Loss of dopamine is responsible for the movement symptoms seen in people with Parkinson’s disease. To help levodopa reach your brain (as opposed to other parts of your body), levodopa is combined with carbidopa. Once it reaches your brain, it’s converted into dopamine.
