Neuropeptides, neurotransmitters and anxiety disorders

As outlined on the slide, many different neuropeptides have been linked to psychopathology, including anxiety, such as the peptide cholecystokinin.³ Cholecystokinin has been shown to induce symptoms of anxiety, especially so in people with anxiety disorders.³ Many neurotransmitters are linked to psychopathology, such as GABA and serotonin in anxiety disorders.^1,2
