Where this comes from

Abstract

The UK is experiencing increasing demand for autism assessments, placing severe pressure on the National Health Service (NHS) and private services. Policy responses remain unproven and cost-driven adaptations have compromised quality of some assessments. This risks misdiagnosis, inappropriate support and growing demand for reassessments, potentially creating greater long-term burden for individuals and services alike.
