Question: What is the relationship between the neurotransmitter GABA and depression? Is it a positive or negative correlation? As in what does an increase in GABA cause? elevated mood or worse depression? In other words, is GABA an excitatory or an inhibitory neurotransmitter?

Answer: It is both excitatory and inhibitory depending on which nerve cluster and structures you are examining. In adults it is mostly inhibitory. Although increasing GABA would likely decrease depression.
