Chemical messengers and neurotransmitters like endorphin, serotonin, GABA, and dopamine work together in a cascade. The brain reward cascade forms patterns of stimulation or inhibition that generate the specific effects involved in producing feelings of well-being and reward.
The GARS® test identifies gene variations that can cause a deficiency or imbalance and interrupt the reward function of the cascade. This can lead to:
- Displaced feelings of well-being
- Cravings for substances
- Behaviors that can provide dopamine
Genetic anomalies, long-term stress, long-term substance use or repeated, compulsive and impulsive behaviors, can cause reward deficiency and lead to a self-sustaining pattern of abnormal craving.
