What this trial studies

This protocol aims to evaluate healthy volunteers and individuals at risk for psychiatric or neurodevelopmental disorders, such as autism spectrum disorder. Participants will undergo a variety of assessments, including psychiatric interviews, cognitive testing, and medical evaluations, to determine eligibility for further research protocols at the National Institute of Mental Health (NIMH). The evaluations will vary based on the specific research protocols and may involve collaboration with other scientists at NIH.

Who should consider this trial

Good fit: Ideal candidates include individuals from 6 weeks of age who are either healthy volunteers or at risk for neurodevelopmental or psychiatric disorders.

Not a fit: Patients who do not meet the consent requirements or those without appropriate guardianship may not benefit from this study.

Why it matters

Potential benefit: If successful, this protocol could enhance the understanding and early identification of neurodevelopmental disorders, leading to better-targeted interventions.

How similar studies have performed: Other studies have shown success in using similar screening protocols to identify and evaluate neurodevelopmental disorders, indicating a promising approach.
