NHS Greater Manchester said the pause is a response to a significant increase in demand across both adult and children’s autism and ADHD services.
NHS GM said: “Across the country, and here in Greater Manchester, demand for autism and ADHD assessments has risen sharply over recent years.
“The number of children and adults waiting has increased year on year and the rate of referrals continues to exceed available capacity.
“This creates very long waits, which we know are difficult for individuals and families.”
It said it was working with providers and partners to develop “a fair and sustainable long-term approach to meet this rising demand”.
“We are also increasing investment in community-based services, self-help resources, digital solutions, coaching and peer support groups, so that people can access practical help and advice while waiting for assessment or support,” a spokesperson said.
“Patients on existing waiting lists will retain their place and their original referral date. We expect non-urgent appointments to resume when the new financial year begins, subject to budget confirmation.
“We recognise how challenging this situation is for families and are committed to improving the timeliness, quality and accessibility of neurodevelopmental services across Greater Manchester.”
