Awhile back I wondered if I had something wrong with my dopamine receptors or transport because I reported symptoms such as anhedonia, decreased libido, and social anxiety. I've been wiki researching and found some really cool things:
"Sociability is also closely tied to dopamine neurotransmission. Low D2 receptor-binding is found in people with social anxiety. Traits common to negative schizophrenia (social withdrawal, apathy, anhedonia) are thought to be related to a hypodopaminergic state in certain areas of the brain. In instances of bipolar disorder, manic subjects can become hypersocial, as well as hypersexual.[citation needed] This is credited to an increase in dopamine, because mania can be reduced by dopamine-blocking anti-psychotics.[25]"
"Deficient dopamine neurotransmission is implicated in attention-deficit hyperactivity disorder, and stimulant medications used to successfully treat the disorder increase dopamine neurotransmission, leading to decreased symptoms.[41] Consistent with this hypothesis, dopaminergic pathways have a role in inhibitory action control and the inhibition of the tendency to make unwanted actions.[42]"
