What Is Dopamine In The Brain What Happens If You Have Too Much Or Too Little Of It
Neurotransmitter: Dopamine is a neurotransmitter. A chemical that enables a neuron to "communicate" with other neurons in the brain. Dopamine has many varied effects in the brain depending on the location in the brain. It can affect movement, e.g. Parkinson's disease involves too little dopamine. In other locations it can affect attention, pleasure, motivation, the "reward center", mood, and prolactin release. ...Read more
Is it true that porn increases dopamine levels in your brain and that your dopamine receptors gets shut down after too much dopamine? Just curious. Ty
Speculative: This is politics and ideology rather than science. I searched the database at the nih for the past 19 years and found a whopping four articles on erotica and dopamine. Naltrexone ends a porn obsession, parkinson's meds trigger a sexual obsession, there's more Dopamine metabolite after watching the stuff, cabergoilne affects sex. The rest is made up as far as I can tell. Put it away, it's stupid. ...Read more
Masturbation or viewing will not do your health much damage. However, by your own admission you are engaging in these activities excessively and that can not be good for your mental health. For good health - Have a diet rich in fresh vegetables, fruits, whole grains, low fat milk and milk products, nuts, beans, legumes, lentils and small amounts of lean meats. Avoid saturated fats. Exercise at least 150 minutes/week and increase the intensity of exercise gradually. Do not use tobacco, alcohol, weed or street drugs in any form.
Practice safe sex. ...Read more
Poor concentration: Dopamine serves many functions in the brian, depending on the specific area in which it is working. In the prefrontal cortex, low concentrations of dopamine result in poor concentration, easy distractibility, irritable mood, and so on. In other areas, it may cause movement disorders. ...Read more
Not exact levels: But dopamine transporter imaging with Single -Photon Emission Computed Tomography (DaT-SPECT) is semiquantitative (not exact levels but ranges) and more of a functional form of imaging (to see where there is dopaminergic activity or the lack thereof). Unfortunately, its not readily available and is more so used research wise. ...Read more
Is akathisia simply caused by a lack of dopamine so if you increase dopamine in the brain does akathisia go away?
No: If only the brain were that simple. Dopamine isn't fuel in a pipe. There are the neurons that produce dopamine, the neurons that have dopamine receptors, & the synapse between them. Put it all together & it makes a Cray computer look like an abacus. (Even your pet rat's brain does.) Akathisia is incompletely understood, but it is infinitely more complex than just not enough juice. ...Read more
IT'S COMPLICATED: The mechanism of action of brain dopamine is not full understood. Low levels are associated with Parkinson's disease and probably ADHD and restless legs syndrome. Your symptoms may reflect depression and there are medications that can increase both brain dopamine and serotonin levels. Pounding heartbeat and tachycardia may be symptoms of panic disorder. You should get a psychiatric evaluation. ...Read more
Naturally means?: Do you mean WITHOUT use of typical pharmacological agents which are prescribed in the U.S. and elsewhere? Tyrosine is an amino acid which is a building block for dopamine. When taken in greater quantities than we get from ingestion dopamine levels will rise in the brain. However, at such necessarily high levels, significant side effects can occur. Needs to be monitored closely by physician. ...Read more
Best lifestyle: One way to increase Dopamine is to exercise, especially a graded, but gentle weight lifting program. If you are asking about stimulants that can be prescribed, I would not endorse that. Taking the precursor tyrosine (an Amino Acid from diet) does not generally improve because of issues getting into brain. Some natural things like rhodiola rosea are thought to help. ...Read more
Increased levels: I believe you are asking what happens when these neurotransmitters are chemically prevented from being metabolized 're-uptake'. This is often accomplished by drugs like anti-depressants. The levels of the neurotransmitters are increased and their physiologic effects are secondarily increased. An example would be subjective feeling of pleasure from increased dopamine. ...Read more
Tough to say: Although the field of psychiatry continues to advance there is still hypotheses about the relationship of specific monoamine neurotransmitters to the diagnoses specified in the dsm-v. If one allows for the possibility of an incomplete heuristic then one would theorize that low Dopamine could predispose to inattentiveness, slowed thinking, impulsivity, decreased energy, anhedonia, and depression. ...Read more
No: Unlike cocaine, there's no chance that a single use will wreck your mind. Even if it's legal, though, I can't recommend it. Life's difficult, and you're at the age in which learning and focusing on things you need to do is critical. Why take something to make you silly? ...Read more
Dopamine production: There is no proven way to increase dopamine. Ingested Dopamine is broken down in the stomach and small intesting (unless combined with a special medication...Carbidopa, for example in the medicine given to Parkinson's patients carbidopa/levodopa). It can be given intravenously, which is done sometimes to help increase blood pressure. See also: http://en. Wikipedia. Org/wiki/dopamine. ...Read more
Chemically or natura: Thrilling behavior, ie. Skydiving, will do it. Gambling will for some, unfortunately do it. Risky, edgy behaviour does it. /c/hemically, drugs to treat parkinson's will increase central dopamine, as will buproprion-a stimulating anti-depressant. Other drugs that treat high prolactins will do it as well, although some treat parkinson's. ...Read more
Everywhere: Both are found throughout the brain, but more common in the limbic or emotional part of the brain ...Read more
No: The drug is a Dopamine agonist, and works as a synthetic mimicker of brain dopamine, but has several drawbacks, including falling asleep while driving due to somnolence. Hallucinations have been reported, and an impulse dyscontrol syndrome has lead to gambling, hypersexuality, and poor judgement. Not a laziness, but rather a behavioral alteration of baseline function. ...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
PET scan: Pet scans in hospitals use glucose metabolism to measure body function. The majority of pet scans are done to look for cancer growth and recurrence there are markers for Dopamine but these are still largely in preclinical or experimental design stages. Besides, parkinson's disease, work is underway to enable pet scans to diagnose alzheimer's disease as well. Excellent question. ...Read more
If my brain is desensitized due to addiction, should I not be avoiding all dopamine increasing activities including exercise?
What is the difference of a maoi and cocaine in terms of what it does to your brain? It looks like they both increase dopamine. :\
Will having more dopamine in your brain lead you to become a better student & do better in school? I heard ADD meds increase dopamine.
Medication: Don't take medication for reasons other than what they are prescribed for and never any other persons medication. See your doctor if you are having issues learning. ...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
How do chemicals in brain like dopamine affect the behaviour, lack of which cause behavioural problems, is there a test to check the levels and cure?
There are three major Dopamine pathways in the brain that help regulate emotions, blood pressure, movements, etc. When overactive can cause psychotic disorders, ; ocd etc. When underactive can cause symptoms of parkinsons.
Most disorders of Dopamine are treated based on symptomatology. Either replace or suppress domanine activity. I am not aware of a generalized test commonly given to ck dopamine. ...Read more
