An Investigation of Early Life Stress and Depression
Early Life Stress and Depression: Molecular and Functional Imaging Approaches
The purpose of this study is to investigate brain pathways within adult females (with a history of CSA that occurred between the ages of 5-14) with and without a current diagnosis of major depressive disorder (MDD).
Hypotheses:
The CSA/MDD participants will be characterized by (1) reduced reward responsiveness and prefrontal cortex activity, but increased cortisol levels, (2) reduced dopamine activity, and (3) reduced dopamine transporter binding. The over-arching purpose of the study is to (1) identify individuals at risk for psychopathology and maladaptive behavior, (2) prevent re-victimization, and (3) develop more targeted therapeutic interventions.

Detailed Description
This study will include four sessions:
Session 1 (SCID Session) The first session takes place at the Center for Depression, Anxiety, and Stress Research (CDASR) or Neuroimaging Center (both at McLean Hospital) and involves consenting, a clinical evaluation, a series of questionnaires, and a medical assessment.
Session 2 or 3 (fMRI Session) The third session takes place at the Neuroimaging Center. Using a double-blind design, participants will be administered either amisulpride (50 mg) or placebo. Participants will complete the Monetary Incentive Delay (MID) task during functional magnetic resonance imaging (fMRI) and the Probabilistic Stimulus Selection Task (PSST) afterwards.
Session 2 or 3 (PET Session) This session takes place at Massachusetts General Hospital. 9 mCi of [11C] altropane will be injected by a trained nuclear medicine technician and positron emission tomography (PET) scanning will begin. Prior to the PET scan, a blood serum pregnancy test will be administered for females.
Session 4 (ERP Session) The fourth session takes place at the CDASR and involves an electroencephalography (EEG) recording, the Probabilistic Reward Task (PRT), and collecting saliva samples to assess cortisol levels.

Measure Description |
Time Frame |
---|---|---|
Dopamine Active Transporter Binding Potential
Time Frame: 1 hour PET scan (Session 3)
|
Utilizing 11C-altropane during positron emission tomography (PET) scanning allows us to measure dopamine active transporter (DAT) binding potential. Our outcome measure is Nondisplacable Binding Potential (BPND). BPND refers to the ratio at equilibrium of specifically bound radioligand to that of nondisplaceable radioligand in tissue. *Higher BPND scores indicate greater binding potential |
1 hour PET scan (Session 3)

The Effects of CSA and Diagnosis on PRT Performance Under Acute Stress
Time Frame: 3 hour EEG Session (Session 4)
|
The participant's performance on the Probabilistic Reward Task (PRT) was assessed both before and after an acute stressor.
The PRT is a behavioral task that measures an individual's ability to learn from rewarding stimuli and incorporate this learning into their response style (response bias).
The acute stressor was the Maastricht Acute Stress Test (MAST).
The score obtained is a ratio of the number of times participants correctly choose the high reward stimuli versus the low rewarding stimuli.
Response bias scores range between -1 and +1.
Higher response bias scores indicate a stronger response bias toward high reward stimuli.
A negative response bias indicates a stronger bias toward low reward stimuli.

3 hour EEG Session (Session 4)
|
The Effect of Major Depressive Disorder and Childhood Abuse History on a Reward-related EEG Component (Reward Positivity Component) While Under Stress
Time Frame: 3 hour EEG Session (Session 4)
|
EEG was recorded during the probabilistic reward task (the PRT task). Participants completed the Probabilistic Reward Task (PRT) twice throughout the experiment, once before stress and once after stress. The stressor was the Maastricht Acute Stress Test (MAST). This statistic shows the effect that childhood sexual abuse (CSA) and diagnosis had on a reward-related positivity EEG component recorded during the PRT, before and after stress.

3 hour EEG Session (Session 4)
|
Cortisol Output in Response to a Stress Manipulation
Time Frame: 3 hour EEG Session (Session 4)
|
This statistic shows the impact of the stress manipulation on the participant's salivary cortisol output.
Saliva samples were collected at 5 distinct time points throughout the study session.
The first saliva sample (Cort 1) was collected when the participant began the eeg session.
The second (Cort 2)was taken at the end of the acute stressor.
The third (Cort 3) was taken approximately fifteen minutes after the second.
The fourth (Cort 4) was taken approximately ten minutes after the third.
The fifth (Cort 5) was taken approximately 40 minutes after the fourth.

Effects on Major Depressive Disorder and Childhood Sexual Abuse History on Striatal Activity in Response to Neutral and Reward Cues
Time Frame: 3 hour Drug & fMRI Session (Session 2)
|
This statistic shows the influence of major depressive disorder and childhood sexual abuse history on the strength of striatal activation (caudate, putamen, accumbens) in response to neutral and reward cues during the monetary incentive delay task (MID). Striatal activation is measured using a statistic called a beta weight. A beta weight is a standardized regression coefficient. Higher beta weights mean greater striatal activation and lower beta weights mean less striatal activation. A negative beta weight would indicate a deactivation. |
3 hour Drug & fMRI Session (Session 2)
|
Effects on Major Depressive Disorder and Childhood Sexual Abuse History on Striatal Activity in Response to Neutral and Reward Feedback
Time Frame: 3 hour Session 2 (fMRI session)
|

3 hour Session 2 (fMRI session)
|
The Effect of Diagnosis on Cortisol Reactivity
Time Frame: 3 hour EEG Session (Session 4)
|
This is a measure of area under the curve in relation to ground, a measure of total cortisol output, in response to acute stress. The acute stressor was the Maastricht Acute Stress Test (MAST). The area under the curve includes all 5 cortisol measures, with one measure before the stressor and the other four measures collected after the stressor. Given that the cortisol data were positively skewed, the cortisol measures were normalized via a log transformation prior to calculating the area under the curve. Area under the curve with respect to ground (AUCG) is calculated AUC_g=(((cort2_log + cort1_log) * cort_t1_time) / 2)+(((cort3_log+cort2_log)*cort_t2_time)/2)+(((cort4_log+cort3_log)*cort_t3_time)/2)+(((cort5_log+cort4_log)*cort_t4_time)/2). Cort_logs are the log transformed cortisol output data (ng/ml) and the cort_times are the time spans in between each cortisol assessment. |
