What is Dopamine?

"A compound which exists in the body as a neurotransmitter and as a precursor of other substances including adrenalin."

Compact Oxford English Dictionary: Dopamine

 

Effects

Frontal Lobes

"In the frontal lobes, dopamine plays a role in controlling the flow of information from other areas of the brain.

        Dopamine disorders in the frontal lobes can cause incoherent thought...

        Shortage of dopamine in the frontal lobes may lead to poor memory."

Wikipedia Encyclopedia: Dopamine

 

Pleasure Center

"In addition, dopamine is involved in the chemistry of pleasure. Release of dopamine into that part of the limbic system known as the 'pleasure center' (an area just below the thalamus) causes pleasure. Although meant to reward vital activities such as eating and sex, this same mechanism is responsible for the craving connected with addiction"

Wikipedia Encyclopedia: Dopamine

 

Dopamine Levels

Dopamine and Serotonin

"Since serotonin and dopamine levels tend to counterbalance each other: whenever serotonin is raised dopamine tends to be lowered and when dopamine is raised serotonin is lowered."

Amenclinic.com: Amen Brain System ADD Subtype Checklist

 

"For tryptophan/serotonin levels to rise, tyrosine [a building block of dopamine] levels must be low; conversely, when tyrosine and it's corresponding neurotransmitters are high, tryptophan levels are moderate to low. (Page 16)"

Book: Somer, Elizabeth, M.A., R.D. Food & Mood. Henry Holt and Company, LLC, 1999.

 

Endorphins

"[Endorphins] disinhibit the dopamine pathways, causing more dopamine to be released into the synapses."

Wikipedia Encyclopedia: Endorphin

 

More information about endorphins can be found on the Endorphins page.

 

Limbic System, Too Much Dopamine

"Dopamine also acts in the limbic system, which controls our emotions.

        Overabundance of dopamine in the limbic system is believed to cause paranoia."

Wikipedia Encyclopedia: Dopamine

 

        "Too much dopamine in the limbic system and not enough in the cortex may produce an overly suspicious personality giving to bouts of paranoia or may inhibit social interaction."

Rhyme Of The Ancient Wanderer: Dopamine

 

Nutritional Supplements

"Nutritional supplements can also have a positive effect on brain dopamine levels and help with focus and energy. I often have my patients take a combination of tyrosine (500-1,500 milligrams two to three a day), OPC grape seed or pine bark (1 milligram per pound of body weight) and gingko biloba (60-120 milligrams twice a day). These supplements help increase dopamine and blood flow in the brain and many of my patients report that they help with energy, focus and impulse control."

Refined Carbohydrates

"The great American diet is filled with refined carbohydrates which has a negative impact on dopamine levels in the brain and concentration."
