NCT ID NCT06329245

What the study statuses mean

This study's is highlighted.

Recruitment status, easiest to join first

Recruiting now This study
This trial is taking on new participants right now.
Not yet recruiting
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 Results may not be published yet.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
Stopped early, before it reached the end. That can be for many reasons, including safety.
Cancelled

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.
Approved
The treatment has been approved, so it is available normally rather than through this programme.

When the status isn't known

Summary

This study follows 100 infants and toddlers with either a high or low family risk of autism spectrum disorder (ASD). Researchers will track how prosocial behaviors—like helping and understanding others—develop, along with brain network changes measured by EEG and MRI. The goal is to spot early differences that could lead to earlier diagnosis and support.

What this could mean

Our plain-language read of the trial. This is informational only, not medical advice or a prediction.

What this could lead to
If successful, this study could help identify early signs of autism in infants, leading to earlier support and interventions.
What could go wrong
This is an observational study, not a treatment trial. It may not find clear differences, and results may not apply to all children.

Who can take part

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

Who is studied

The longitude study will be performed in high-risk infants of ASD who have at least one older sibling with a clinical diagnosis of ASD. The low-risk group will also be recruited from healthy infants as control group if they had an older sibling without evidence of ASD and no family history of a first or second-degree relative with ASD.

Ages

0 to 18 months

You do not need to have the condition being studied to take part.

Show the full entry requirements

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

Inclusion Criteria: * Subjects were enrolled as high-risk if they had an older sibling with a clinical diagnosis of ASD confirmed on the Autism Diagnostic Observation Schedule, second edition (ADOS-2) or Autism Diagnostic Interview (ADI-R). * Subjects were enrolled in the low-risk group if they had an older sibling without evidence of ASD and no family history of a first or second-degree relative with ASD. Exclusion Criteria: 1. diagnosis or physical signs strongly suggestive of a genetic condition or syndrome (e.g., fragile X syndrome) reported to be associated with ASDs; 2. a significant medical or neurological condition affecting growth, development or cognition (e.g., CNS infection, seizure disorder, congenital heart disease); 3. sensory impairment such as vision or hearing loss; 4. low birth weight (\<2000 grams) or prematurity (\<37 weeks gestation); 5. possible perinatal brain injury from exposure to in-utero exogenous compounds reported to likely affect the brain adversely in at least some individuals (e.g., alcohol, selected prescription medications); 6. contraindication for MRI (e.g., metal implants); 7. a family history of intellectual disability, psychosis, schizophrenia or bipolar disorder in a first-degree relative.
