It can lead to a form of addiction – and as many recovering addicts will testify, it finally gets to the point that the activity no longer brings pleasure – but they are compelled to continue with the behavior simply in order to keep from feeling bad.ĭopamine agonists such as aripiprazole activate dopamine receptors in the brain, literally opening up those pathways. Each “near miss” encourages the subject to keep laying his or her money down. Unfortunately, those dopamine pathways do not know the difference between improving a skill by one's own efforts and getting lucky.
It is what keeps a musician practicing scales and etudes, and motivates an athlete to continue training. This can be a good thing when it comes to activities involving the development of mental and physical skills. It is not just signaling pleasure in achieving one's desires, it also indicates how close the subject came to success – and encourages him or her to keep trying. In a 2010 study of roulette players, researchers found as much dopamine activity in the brains of gamblers who had just missed hitting the lucky numbers as those who had won the jackpot. It is what keeps addicts searching for the next “high.” When it comes to compulsive behaviors such as gambling, dopamine encourages the subject to keep trying, even when they lose. Those pathways activate even in cases in which the subject has come close to the desired reward, but has fallen just short of obtaining it. It doesn't simply activate the reward pathways of the brain when one has achieved a desired result. More accurately, it is a signal that tells the brain when one is closing in on a reward. Dopamine is not simply a “feel good” chemical. However, it is a bit more complicated than that.
Guardian described dopamine as “the nerd at the pool party who gives a running commentary on how well you're doing with the temptations on offer.” While dopamine has many different functions – including muscle control, regulating kidney function and as a vasodilator – it is most often associated with the brain's “pleasure centers,” playing a significant role in addictive behaviors. It is part of a class of drugs known as “dopamine agonists,” although aripiprazole itself is classified as a “partial dopamine agonist.”ĭopamine is a biochemical substance in the brain that functions as a neurotransmitter – in other words, it carries signals to and from the brain. Originally given the green light by the FDA in 2002, Abilify was approved for the treatment of depression in 2007. Aripiprazole, sold by Bristol-Meyers Squibb under the trade name Abilify, is an atypical, or “second generation” antipsychotic medication usually prescribed for the treatment of schizophrenia, bipolar disorder and depression.
