Core Tip

Core Tip: Deep brain stimulation (DBS) is a medical treatment that aims at obtaining therapeutic effects by applying chronic electrical impulses in specific brain structures and neurological circuits. Autism spectrum disorder comprises a group of developmental disabilities that are often associated with numerous medical and psychiatric comorbidities that worsen the quality of life of patients and their caregivers. Comorbidities often require multiple drug treatments with an increasing rate of treatment resistance. Thirteen studies have been considered in this paper. Up to date, DBS has been used for the stimulation of the nucleus accumbens, globus pallidus internus, anterior limb of the internal capsule, ventral anterior limb of the internal capsule, basolateral amygdala, ventral capsule and ventral striatum, medial forebrain bundle, and posterior hypothalamus. In the total sample of 16 patients, 4 were adolescents (all males), and 12 were adults (5 males and 7 females). All patients had symptoms resistant to multiple drug therapy. Only one patient was considered not a responder to DBS. Among the new therapeutic perspectives, as evidenced by the studies presented in this article, DBS could be a valid option. However, further, and more in-depth research is needed in this field.
