These suggest that an imbalance of certain neurotransmitters may contribute to anxiety. It was found that the chemical serotonin plays a major role in anxiety disorder patients.
Anxiety disorders also have been proven to be genetic. Forty percent of people diagnosed with anxiety have a close relative with the same disorder. The UC Davis report states that there is a particular interest in possible defective genes that regulate specific neurotransmitters, including serotonin and dopamine.
