"Girls with Autism - Imaging in Neurodevelopment"
Age: 2-3.5
Healthy Volunteers: Yes
Keywords: asd, autism, mri, development, toddlers, behavior
Type: Observational
The GAIN Study started several years ago to bring more girls into research. Boys are diagnosed with autism about 4-5 times more often than girls. Because of this, girls are frequently excluded from autism research studies altogether. We hope to identify differences between boys and girls in order to guide more directed treatments and intervention. Participation will involve a variety of testing methods, including looking at your child’s behavior (through questionnaires and on-site assessments, biology (through a brief medical exam and blood draws on child and parents) and brain (through a nighttime MRI). There will be 2-3 visits scheduled over a 2 month period for the first year, and we would like to track your child’s development over three years. We are currently enrolling both girls with autism and without autism in order to understand how girls and boys with autism may differ.
This study requires

This is a longitudinal study that will initially span three years.

During the first year, participation involves 2 half-day visits to the UC Davis MIND Institute for behavioral assessments, medical examination, and a blood draw. You will return for an evening visit to complete the sleep MRI scan at the Imaging Research Center.

For some families living further distances away from the MIND Institute, visits may be scheduled in one 2-day visit, with hotel accommodations provided. We try to schedule the visits at your convenience, given the availability of staff and resources.

One year later, your child will be asked to return for a repeat MRI scan.

Two years after your first visit, your child will be asked to repeat some of the behavioral tests and a repeat MRI scan.

Who can participate

Girls between the ages of 2 to 3-1/2 at the time of the first visit
