Summary

This trial is testing the feasibility of using electroencephalography (EEG) to study adolescent anorexia nervosa (AN), with the goal of eventually replacing more costly and difficult-to-access fMRI.

Who is the study for?
This trial is for girls aged 11-17 with Anorexia Nervosa (AN), specifically the restricting type, and healthy controls within a similar age range. Participants must have a body weight below 17.5 BMI if diagnosed with AN or between 90-110% of average body weight if they are healthy controls. All participants should be right-handed as per the Edinburgh Handedness Inventory, speak English primarily, and for those with AN, be in their first weeks of treatment at specified centers.
What is being tested?
The study aims to develop an EEG-based method to investigate prediction error responses in adolescents with AN compared to healthy controls. It will adapt existing fMRI protocols for EEG use and test whether these can reliably measure brain responses related to reward processing errors across different stimuli like taste and money.
What are the potential side effects?
Since this trial involves non-invasive EEG testing rather than medication or invasive procedures, there are minimal expected side effects. The main concerns may include discomfort from wearing the EEG cap or stress from participating in the tasks required by the study.
