Dopamine Serotonin Norepinephrine
Please explain what levels of neurotransmitters a tourette patient has to have, serotonin, dopamine, adrenalin & norepinephrine, thank you?
Go after it!: Kenneth, that's a great question. I encourage you to get a Ph. D. in neurobiology and devote your career to finding out the answer, because if you do, you will win about three Nobel Prizes in Medicine. In fact, you'll win if you can find an effective way to measure neurotransmitters in the living brain all at once for more than a minute at a stretch AT ALL, let alone for Tourette's. ...Read more
Does ibuprofen raise or lower levels of serotonin dopamine or norepinephrine in the brain? Or something else?
There are no levels: There are no "levels" of neurotransmitters (NTs) in the brain. They don't just float around freely as if in blood. NTs are constantly being dynamically synthesized in neurons, being released into synaptic clefts, & within milliseconds undergoing reuptake either before or after the molecules have been destroyed & recycled into making more NTs. Furthermore, NTs differ depending on the brain region. ...Read more

Atomoxetine inhibits serotonin transporter, dopamine transporter and naroephinephrine. What does inhibit mean?
Strattera (atomoxetine): Inhibition is the opposite of stimulation, so the effectiveness is reduced. ...Read more
Sine seratonin depletes other nerotransmitters like dopamine, norepinephrine, and epinephrine...By "deplete" does it mean a permanent thing?
Not correct: Serotonin does not deplete other neurotransmitters, but there is a balance especially between Dopamine and serotonin. This balance is dynamic and constantly re-establishing itself. Unless there is damage to neurons (which there can be when abusing certain drugs) neurotransmitter changes would not be permanent. ...Read more
Receptors: These three medications are used to support the heart and cardiovascular system ie. blood pressure and heart rate. They are known as sympathomimetics and have a similar response to what you would think of as adrenaline. Each has variable effect on either heart rate, heart function (in terms of strength of 'squeeze') and on blood vessels which would translate to higher blood pressure. ...Read more
Well-many: This is a complex question, and the answer is many. The number of receptors for both of these are throughout the brain and body and are controlled by different biochemical processes which trigger excretion, secretion, reuptake, and distribution. There are different types of serotonin and dopamine receptors throughout the systems. ...Read more
I was wondering what are the differences of levophed, (norepinephrine) dopamine and dobutamine in terms of their action?
You Asked for It----:
Dobutamine- direct b1 receptor stimulant or agonist in the sympathetic nervous system.
Levophed- vasoconstrictor peripherally (alpha adrenergic effects) and beta adrenergic stimulant at the level of the heart and coronary vessels
dopamine- dual b1 and Alpha adrenergic effects. Useful in hypovolemic shock because of conservancy of renal blood flow. Also, works centrally in other complex ways. ...Read more
I know serotonin and dopamine are the main "happy chemicals" in your brain. What is the difference in the feelings/types of happiness they cause?
Calm vs. Excited: The role of neurotransmitters in feelings is complex, but serotonin is involved in a sense of calm joy as from meditation or marijuana, whereas dopamine is related to a state of excitement- sometimes called the sex, drugs & rock'n'roll neurotransmitter, as from cocaine. Deficiencies or excess of each creates problems. See http://www. Buzzle. Com/articles/neurotransmitters-and-their-functions. Html ...Read more
Serotonin is a neural transmitter primarily found in the gastrointestinal tract, platelets, and in the central nervous system.
Dopamine is a neurotransmitter that helps control the brain's reward and pleasure centers. Dopamine also helps regulate movement and emotional responses, and it enables us not only to see rewards, but to take action to move toward them. ...Read more
Serotonin: They are all neurotransmitters.Get a more detailed answer ›
Catecholamines: Behavior is much more complex than neurotransmitter levels alone. But norepinephrine (ne) acts mainly in an area of your brainstem called the locus coeruleus. When released, ne triggers the stress response. Ne is also involved in pain, cognition, mood, emotions, movement and blood pressure. Dopamine is involved in regulating mood, pleasure, delusions, psychosis and drug abuse -- and more. ...Read more

Wellbutrin (bupropion): Wellbutrin (bupropion) acts by enhancing the levels of serotonin, dopamine, and norepinephrine at the site of each neurotransmitter. For this reason, it's an excellent medication choice for depression and executive functioning, such as conditions with attention and concentration impairments. However, due to its actions upon dopamine, it is relatively contraindicated in psychotic conditions. ...Read more
Yes: The caffeine in coffee blocks Adenosine receptors, which when activated make you tired and sleepy. This blockade also affects all major neurotransmitters, such as dopamine, acetylcholine, serotonin -- and in high doses, norepinephrine too. Dopamine effects are not in the exact same regions of the brain that other addictive substances affect, though. ...Read more
What are the effects of prolonged anxiety and anger on acetylcholine, serotonin, dopamine levels?
Negative emotions: Strongly impact our biochemistry in general. They can eventually burn out our adrenal glands. For a lab analysis of neurotransmitters via urine your doc can use neuroscience lab, who specialize in this, along with supplemental formulas to balance things naurally. Peace and good health. ...Read more
I'm having a very addictive behavior I think my dopamine is high and I'm on Cipralex I know it raises serotonin but can it lower dopamine as well?
Yes, since: Acetylcholine is the preganglionic transmitterGet a more detailed answer ›
Are there any ways to ease the withdrawal illness while coming off of serotonin norepinephrine reuptake inhibitors?
At 113 mg efexor had no effect on anxiety. At 150 it helped a lot. Does this imply that norepinephrine was more of an issue for me than serotonin?
If you mean....: ....That at the150mg dose you most likely started to get the effect that Effexor (venlafaxine) can have on norepinephrine, you are probably correct. At the lower doses Effexor (venlafaxine) only works on serotonin. It is possible you may get even more effect on norepinephrine at doses higher than 150. Typically at doses higher than 225, the effect on Dopamine can kick in as well. Hopefully you are tolerating the drug well! ...Read more
If a certain meditation releases a lot of dopamine/serotonin, etc; is there a probability that overdoing it could down-regulate receptors in my brain?
Serontinergic: Receptors do down regulate when a medication is used, they up regulate when there is no seratonin. Down regulation of Dopamine receptors does occur in cases of abuse with cocaine, high dose amphetamine, etc, not with common medications for mood. Also people may have different levels of receptors without meds, thrill seekers needing more Dopamine release to feel a charge, . ...Read more
