This article provides an overview of the importance of mental health in the success of disengagement and deradicalization processes. Psychotherapeutic professionals, with their expertise in the structures, conflicts, and dynamics of the human psyche, can contribute significantly to working with clients experiencing psychological stress or mental illness. Through the NEXUS Psychotherapeutic- Psychiatric Counseling Network, and three practical models, the integration of psychotherapeutic skills is illustrated: (1) Psychotherapeutic family support, (2) Consultative assistance for social-pedagogical exit programs, and (3) Case-specific consulting for the social justice services. Each model serves as a bridge, providing access to psychotherapeutic or psychiatric care for individuals caught up in radicalization dynamics in various ways. The article also discusses the experiences of collaborating with specialized advisory centers, and outlines challenges at the intersection of child and youth welfare, public safety, and the justice system. Key structural elements for creating sustainable frameworks of cooperation are identified to help individuals leave extremist paths, process their experiences and actions, and make a fresh start. A case study of good practice is also recognized.
