A Holyrood committee has called for a full review of how attention deficit hyperactivity disorder (ADHD) and autism are assessed in Scotland, warning that long delays are leaving many people without vital support. The Health, Social Care and Sport Committee found that waiting times for neurodevelopmental assessments can stretch into years, with some health boards closing their lists entirely.

In a newly published report, the committee said growing demand for assessments reflects better awareness and historic underdiagnosis, rather than an increase in inappropriate referrals. Members argued that inconsistent access across the country is unfair and can prevent individuals from accessing reasonable adjustments, treatment options or support that would allow them to participate fully in education, work and society.

The committee is calling for a national standard for autism and ADHD assessments to ensure consistent, high-quality provision regardless of location. It also stressed the importance of clear and reliable pathways into post-diagnosis support, noting that a lack of diagnosis can leave people excluded from services even when their needs are evident. The report highlights that prolonged waits can push individuals into crisis, increasing pressure on already stretched services.

Alongside assessment reform, the committee recommended improved national monitoring of referrals and waiting times, including regular reporting and the development of a comprehensive data dashboard. It also urged a joined-up approach across health, social care, education and other public services, with better workforce planning, integrated funding, inclusive education and stronger support for families, to improve outcomes for neurodivergent people across Scotland.
