Radicalisation in adolescents: mental health considerations for violent extremism.

Objective: To outline current understanding and recommended mental health and psychiatric considerations for radicalisation and violent extremism among adolescents.

Method: Overview of recent research regarding violent extremism in adolescents and relationships with mental illness and other psychosocial determinants. Relevant international and Australasian research is outlined, with an emphasis on adolescents. Psychiatric considerations, intervention and policy implications will be explored.

Results: Adolescents who become radicalised form a heterogenous group with complex, multifaceted needs from mental disorder, familial, societal and/or environmental contributions. Thus, assessment and management need to be individualised. Mental health clinicians working with at-risk and radicalised adolescents should maintain a high index of suspicion for mental illness (particularly psychosis and depressive disorder) and neurodevelopmental disorder. Identified psychiatric conditions warrant prioritised mental health treatment. There may be a relationship between specific psychopathology and certain ideological beliefs and behaviours.

Conclusions: Radicalised adolescents pose challenges with risk of serious harm to others, presentation complexity, multifactorial contributors and associations with varied psychopathology. All adolescents at risk of radicalisation or who are radicalised, should receive comprehensive mental health assessment and prompt assertive treatment of identified psychiatric conditions.
