SAN DIEGO, Calif.--The brain's dopamine system, which has long been associated with reward learning and reward-related behavior, works differently in treated and untreated attention deficit hyperactivity disorder (ADHD) individuals, according to a study presented by German researchers at SNM's 53rd Annual Meeting June 37 in San Diego.... ...

For all of the promise embryonic stem cells hold for therapies for neurodegenerative diseases such as Parkinson's disease, they are notoriously difficult to use. One problem is in coaxing them into becoming brain cells that make dopamine, which is in short supply in the brains of individuals with Parkinson's. Such cells might be used for transplantation in these patients, but current methods invo...Discovery of new dopamine action may yield alternative psychiatric drugs
Durham, N.C. Duke University Medical Center researchers have discovered a new mechanism by which chronically high levels of the neurotransmitter dopamine exert their effects on the brain. Normally associated with triggering feelings of pleasure, excess concentrations of dopamine underlie schizophrenia, attention deficit hyperactivity disorder and other psychiatric conditions. The findings theref...Flies on speed offer insight into the roles of dopamine in sleep and arousal
Methamphetamine, the drug of choice for long-distance truckers and college students pulling all-nighters, appears to do a similar trick for fruit flies, too. This finding is one of several in a new study that demonstrates a critical role for the neurotransmitter dopamine in the modulation of sleep, wake, and arousal states. ......

Researchers have discovered that antidepressant drugs such as Prozac not only affect levels of the neurotransmitter serotonin in the brain, but also "hijack" dopamine signaling as well--causing it to launch serotonin signals. Their findings offer new insight into how Prozac and other "selective serotonin uptake inhibitors" (SSRIs) work and how they might cause problems in patients taking them. .....
