Descripción
Inclusion Criteria:
- Age 18+ years
- Documented enrollment in residential-level treatment at The Emily Program and meeting criteria for AN (BMI <18.5).
- Participant must be capable of giving informed consent, based on University of California San Diego (UCSD) Brief Assessment of Capacity to Consent (UBACC)39 risk assessment, which has been uploaded to ETHOS.
- Sufficient spoken English so as to be able to comprehend testing procedures.
Exclusion Criteria:
- Substance abuse in the participant
- Neurological condition or other developmental disorder
- Serious psychiatric disorder known to affect brain functioning and cognitive performance
- Medical instability, which will be evident based on required admittance status in the residential treatment facility from which participants will be recruited. (The Emily Program residential treatment patients are followed closely by a medical provider, who routinely assesses medical stability throughout the duration of each patient's stay in the treatment facility; therefore, if a participant is not currently a patient in this setting and/or has been recently discharged from residential treatment setting due to medical need to receive higher level of care/inpatient-level care, they will be excluded from enrollment in this study).
- MRI contraindication [based on Center for Magnetic Resonance Research (CMRR) prescreening protocol]
- tDCS contraindication (e.g., history of craniotomy, history of metallic cranial plates, screws, implanted devices).

Experimental: Active tDCS
Participants will receive 10 sessions of active tDCS + cognitive training.
|
Transcranial direct current stimulation, involving low-levels of electrical stimulation applied to the right and left DLPFC will be used in conjunction with cognitive training for 46 minutes.
|
|
Comparador falso: Sham tDCS
Participants will receive 10 sessions of sham tDCS + cognitive training.
|
Sham transcranial direct current stimulation, involving no electrical stimulation will be used in conjunction with cognitive training for 46 minutes.

Medida Descripción |
Periodo de tiempo |
|---|---|---|
|
Number of participants with treatment-related adverse events as assessed by CTCAE v4.0 and rate of treatment dropout in treatment-seeking adults with AN receiving treatment in a residential treatment program for eating disorders.
Periodo de tiempo: Through study completion, an average of 1 year.
|
Treatment-related adverse events will be assessed by CTCAE v4.0 criteria.
Participant dropout will be examined in effort to evaluate whether individuals with AN will tolerate the procedures and remain in the study.
This will be evinced by less than 20% dropout over the course of active tDCS and cognitive training.
|
Through study completion, an average of 1 year.
|
|
Change from Baseline to End of Treatment Set-Shifting Task Performance Following 10-session tDCS + Cognitive Training Intervention Protocol.
Periodo de tiempo: Through study completion, an average of 1 year.
|
Changes in cognitive flexibility will be assessed by examining differences between baseline and end of treatment performance on reversal learning task.
|
Through study completion, an average of 1 year.
|
|
Change from Baseline to End of Treatment Resting State and Task-based Functional Magnetic Resonance Imaging (fMRI) Activation during Reversal Learning Task Following 10-session tDCS + Cognitive Training Intervention Protocol.
Periodo de tiempo: Through study completion, an average of 1 year.
|
Changes in brain circuitry assessed during resting state and task-based fMRI will be assessed to examine whether active tDCS is associated with greater change in associated circuitry, as compared with sham tDCS.
|
Through study completion, an average of 1 year.

Change in Eating Disorder Examination (EDE) Scores from Baseline to End of Treatment
Periodo de tiempo: Through study completion, an average of 1 year.
|
Change in eating disorder psychopathology, measured by the EDE, will be evaluated over the course of a 10-session tDCS + cognitive training intervention to determine whether tDCS is associated with significant change in eating pathology among individuals with Anorexia Nervosa.
|
Through study completion, an average of 1 year.
