Avoidance behavior is an adaptive strategy of animals to cease the occurrence of adverse events by facilitating or not facilitating certain actions. Driven by the reward-related processing and fear conditioning, moderate avoidance behavior is essential to the survival of organisms as it helps to hedge risks and save energy. On the other hand, maladaptive avoidance behavior, which individuals over-generate or unable to remove is often associated with psychiatric disorders, and what’s more worsen the condition and affect the treatment. Reflecting on the recent researches on avoidance forming and its physiological and pathological mechanisms, this paper demonstrated that as it was the combination of logic decision-making and adaptive fear guided the arise of avoidance, its acquisition and regulation involved multiple brain areas serving in the reward and punishment system, as well as different conditioned reflexes. The maladaptation of avoidance behavior is often caused by organic changes of the brain and associated with behavioral abnormalities. This paper summarized the current intervention on avoidance behavior, and found such techniques inadequate. Then analyzed the feasibility of reducing maladaptive avoidance through low- frequency repetitive transcranial magnetic stimulation (rTMS) based on 3 aspects: ① its principles, development and applications, ② the role of the prefrontal cortex (PFC) in avoidance regulation, ③ previous work on interfering avoidance through rTMS on the PFC. In the end, this paper demonstrated an outlook of facilitating low-frequency TMS as an intervention on maladaptive avoidance and the value of conducting follow-up studies.
