Neurodevelopmental and Behavioral Phenotyping Screening Protocol

This study is looking for healthy volunteers and individuals at risk for mental health conditions or neurodevelopmental disorders, like autism spectrum disorder. The goal is to carefully evaluate participants to see if they might be a good fit for other research studies at the National Institute of Mental Health (NIH). You would undergo various evaluations, which could include interviews about your mental health and development, cognitive (thinking) tests, and a medical history. The study is open to people aged 6 weeks and older, of all genders. The success of this study is measured by these ongoing screening evaluations.

Study design
This is an observational study, meaning no specific intervention is being tested. It plans to enroll up to 5000 participants.
What's involved
You would undergo screening evaluations, which may include interviews, developmental/cognitive testing, and a medical history. Some evaluations might also involve neuropsychological testing, a physical exam, blood tests, and a request for medical records.
Compensation
Not stated in the trial record.
Follow-up
The primary evaluations are measured as ongoing, suggesting continuous assessment rather than a fixed follow-up period after treatment.
