Neurodiversity and Radicalisation – Resilience in Unity (Online)

Vulnerabilities in Extremism

The intersection of neurodivergence and radicalisation has gained urgency in the UK, where data from 2025 shows a sharp rise in referrals to the Prevent programme. Autistic individuals, comprising 14% of the 8,778 referrals in the year ending March 2025, are disproportionately flagged, often due to misinterpreted behaviours like intense online interests rather than actual extremist intent. This surge reflects broader societal shifts, including the proliferation of algorithmic content that exploits isolation and cognitive rigidity, common in autism spectrum disorder (ASD) and attention-deficit/hyperactivity disorder (ADHD).

Real-world impacts are profound, affecting young males in particular, who may face social exclusion and turn to online communities for belonging. In prisons, where up to 31% of minors convicted of terrorism offences since 2016 have neurodivergent diagnoses, lack of tailored support exacerbates risks. Families and clinicians report that traits such as black-and-white thinking or need for structure can align with extremist narratives, but without proper intervention, this leads to exploitation rather than empowerment.

Concrete stakes include deadlines in the Cross-Government Neurodiversity Action Plan, rolled out in October 2025, which mandates new digital tools for sharing prisoner needs across estates. Costs run high: misreferrals waste counter-terrorism resources, estimated in millions annually, while inaction heightens isolation, with 2025 cases showing autistic youth radicalised online in months, facing life sentences. Risks of inaction are stark—untreated vulnerabilities correlate with higher recidivism, as seen in 45% of extreme-right minors with diagnoses.

Non-obvious tensions arise between safeguarding and over-securitisation: while frameworks like the ERG-R now incorporate neurodivergence, they risk pathologising differences, alienating communities. Counterarguments highlight no causal link exists, with stigma deterring help-seeking; surprising data from Dutch studies show half of neurodivergent extremists are foreign fighters, blending migration stressors with online radicalisation. Trade-offs pit privacy against prevention, as algorithmic exploitation—unaddressed by tech firms—fuels a cycle where neurodivergent individuals, already underserved, bear disproportionate scrutiny.
