By depression there is a decreased amount of neurotransmitters in parts of the central nervous system, mainly deficiency of serotonin, but also to some extend of noradrenalin, acetylcholine, dopamine or gamma-amino-butyric acid (GABA), or the nerve cells do not react correctly by stimulation from neurotransmitters. A neurotransmitter is a signal substance that transmits the nerve signal by the junctions amongst two nerve cells.
Serotonin and noradrenalin result in nerve cells to send impulses along to other nerve cells, and therefore enhance the activity in the brain. Deficiency of these substances causes slowness in elements of the brain, and that once again causes the depressive symptoms.
The function of GABA is the opposite, namely to slow down some nerve impulses, primarily these creating anxiousness and panic response. Lack of GABA causes increased anxiety and simpler panic response. But, lack of this transmitter also seems to cause depressive signs and symptoms. This is due to the fact a too large activity in some brain processes can slow down other processes.

The medicines mainly implemented at the moment improve the serotonin concentration by decreasing the removal of serotonin from the area around nerve cells. Examples of this medication type are: Fluoxetine (Prozac), fluvoxamine (Luvox), paroxetine (Paxil), escitalopram (Lexapro, Celexa), sentraline (zoloft).
By bipolar disorder in the manic face, heavy tranquilizers (neuroleptica) are utilized to cease the manic signs. By bipolar disorder, lithium salts are frequently implemented to stabilize the situation, and protect against new outbreak of depressive or manic faces.
