On a neurological level depression seems to be caused or at least indicated by changes in neurotransmitter levels and/or changes in the neurotransmitter-receptor sensibility towards neurotransmitters. Consequently, most antidepressants target this mechanisms where they act by increasing the neurotransmitter levels in the brain. Depending on which type of antidepressant is used the mode of action is slightly different.

Serotonin/norepinephrine reuptake inhibitors and Tricyclics Antidepressants block the re-uptake and the destruction of the neurotransmitters Norepinephrin and Serotonin, while Selective Serotonin Reuptake Inhibitors only block the re-uptake of Serotonin, and Monoamine Oxidase Inhibitors work through blocking the breakdown of neurotransmitters. Other depression drugs with different mode of action also exist.
