Does increased GABA cause anxiety?

Gamma-aminobutyric acid (GABA) a chemical made in the brain. As an inhibitory neurotransmitter, GABA reduces a nerve cell's ability to send and receive chemical messages throughout the central nervous system. Fluctuating levels of GABA are linked to medical conditions including anxiety, autism, and Parkinson's disease.

Is GABA high or low in anxiety?
