Intellectual Disability and Mental Health: Assessing the Genomic Impact on Neurodevelopment (IMAGINE ID)

Aims
The Intellectual Disability and Mental Health: Assessing the Genomic Impact on Neurodevelopment (IMAGINE ID) is a national longitudinal cohort study on the genetic causes of intellectual disability. The study aims to analyse how genetic changes affect children and young people's behaviour and to inform the care of families and children both now and in the future.

IMAGINE ID encompasses IMAGINE-1 (2015-2020) and IMAGINE-2 (2020-2024), and follows two cohorts, one based in University College London and one based in Cardiff University.
