Biochemistry of Depression
Doctor Jon Lieberman discusses three neurotransmitters that have been associated with depression - dopamine, serotonin, and norepinephrine.
There are three major neurotransmitters associated with depression. The one we hear most about these days is serotonin, there is dopamine, and there is norepinephrine. I would like to say a little bit about dopamine because dopamine deficiency is found in the synapses of people who are drug-dependent or engage in compulsive behavior - compulsive gambling, compulsive spending, compulsive shopping. The major area of the brain that seems to be affected by substance abuse and compulsive behaviors is the nucleus accumbens.
