Conceptual framework links predostatic mind dysregulation to addictive behaviors across psychiatric domains, suggesting pathways for tailored clinical interventions.

Key Points

To introduce an integrative, dynamic, and transdiagnostic model (DREXI3) that explains addiction through the dysregulation of predictive homeostatic brain mechanisms.
Conceptualized a predictive homeostatic ('predostatic') paradigm where emotions and behaviors operate to regulate risk and reward balance.
Defined three distinct operational modes (Alarm, Seek, and Balance) and mapped addiction onto six transdiagnostic symptom dimensions using hypothetical clinical illustrations.
Characterized addiction as chronic hyperactivation of Seek Mode (driven by reward prediction) and Alarm Mode (driven by imminent risk prediction), which impairs the self-regulating Balance Mode.
Outlined six primary dimensions of dysregulation: neurophysiological alterations, impulsivity, compulsion, cognitive impairment/psychosis, mood disturbances, and anxiety or anger.
Established a framework to unify clinical evaluation and neuroscientific insights to support individualized addiction therapy.
