Neurotransmitters are chemicals that are released from one neuron to another nearby neuron as a means of passing a signal from one to the next. Many mental health conditions seem to arise from biochemical disruptions leading to (or ameliorated by correction of) excesses or deficits of these neurotransmitters. In this entry, an overview of the mechanism of neurotransmitter function is followed by the ways in which this mechanism can be altered with medication. The major types of neurotransmitters are delineated, with the common mental health conditions associated with each.
