Study of Toddler Language Development

Location: Bethesda, MD
Start Date: February 24th, 2015
End Date: February 24th, 2017

Researchers at the National Institute of Mental Health are seeking toddlers 12 or 18 months of age with language delays (i.e., no words at 18 months, limited vocalizations at 12 months) or typical development to participate in a study examining communication development. Most children with language delays do not develop autism. However, we hope this study will help inform us about the risk factors.

This study will involve both outpatient and inpatient (overnight) visits and will be conducted at the NIH Clinical Center in Bethesda, Maryland. Following an initial screening evaluation, eligible participants will complete an overnight sleep study/EEG and an MRI scan. Follow-up visits that include behavioral assessment will occur every 6-12 months. The final study visit will occur at 36 months of age and will involve behavioral assessment, sleep/EEG study, and MRI.

Compensation will be provided. If you are interested please call 301-435-7962 (TTY: 1-866-411-1010) or e-mail
