Abstract
Bipolar and related disorders (BD) are characterized by frequent deregulation and changes in mood and energy states. The neurobiological mechanisms underlying these changes remain unknown. The cerebellum has recently demonstrated its role in emotional and behavioral regulation in psychiatric illnesses and may be an essential structure for mood regulation and clinical stabilization in bipolar disorder. Modafinil has demonstrated efficacy in improving and controlling symptoms of bipolar depression through its control of symptoms such as fatigue, drowsiness, and regulation of wakefulness levels. However, since this drug also showed effects on mood improvement and treated BD patients do not have an increased risk of manic episodes, it appears to have mood-stabilizing effects whose neurobiological mechanisms are not yet established. In this regard, recent research has demonstrated the modulating effect of modafinil on the connectivity of the cerebellum and cortex. This article explores the interaction between this effect and its possible interference in maintaining euthymia in bipolar disorder.
