NCT ID NCT07570381

What the study statuses mean

This study's is highlighted.

Recruitment status, easiest to join first

Recruiting now
This trial is taking on new participants right now.
Not yet recruiting This study
Registered, but not yet taking participants.
By invitation only
Not open to general applications. Only people the study team invites can take part.
Paused
Paused for now. It may or may not start again.
Ongoing
Running, but no longer taking on new participants.
Completed
The trial has finished. Results may not be published yet.
Stopped early

Cancelled
Cancelled before anyone took part.

Expanded access (not trials)

Expanded access
Not a trial. This treatment can be requested outside a study, case by case, for people who qualify.
Expanded access (paused)
Not a trial. The treatment can normally be requested outside a study, but is unavailable right now.
Expanded access (ended)
Not a trial. The treatment could once be requested outside a study, but no longer can.

Summary

This study is looking for early clues—like brain activity, genetics, and environment—that might predict autism, ADHD, and related mental health issues in children and young adults. Researchers will follow 800 participants from infancy through young adulthood across 10 international sites. The goal is to better understand these conditions and pave the way for personalized prevention and treatment strategies.

This study's own entry requirements. Only the study team can say for certain whether you qualify.

Who is studied

The study will recruit approximately 800 participants from early infancy to young adulthood across 10 international sites. OS1 will include infants at increased neurodevelopmental risk: very or extremely preterm infants (\<32 or \<28 weeks), term-born infants with perinatal asphyxia or hypoxic-ischaemic encephalopathy, and a comparison group of term-born infants without risk factors. Infants are enrolled within the first 12 months and followed to 42 months. OS2 will include children (5-10 years), adolescents (11-18 years), and young adults (19-25 years) with confirmed diagnoses of ASD, ADHD, or DCD, conditions linked to elevated anxiety and depression risk. Recruitment aims for balanced sex representation and diverse socioeconomic and cultural backgrounds.

Copied word for word from the study's registry entry, so the wording is the study team's rather than ours.

OS1 Inclusion Criteria: * Infants born very preterm (\<32 weeks) or extremely preterm (\<28 weeks); or * Term-born infants with documented perinatal asphyxia and hypoxic-ischaemic encephalopathy (HIE); or * Term-born infants with no risk factors (comparison group). * Must be ≤12 months corrected age at enrolment. OS1 Exclusion Criteria: * Syndromic, chromosomal, or known genetic conditions. * Motor impairments that would prevent participation in psychometric or neurophysiology assessments. OS2 Inclusion Criteria: * Individuals aged 5-25 years. * Clinical diagnosis of ASD, ADHD, or Developmental Coordination Disorder (DCD). * Able to participate in scheduled assessments. OS2 Exclusion Criteria: * Severe motor impairments that limit psychometric assessment. * Diagnosis of schizophrenia, due to confounding neurocognitive effects.
