Inflammation and Electroconvulsive Therapy
Does Electroconvulsive Therapy Cause Neuroinflammation? An [18F]FEPPA Positron Emission Tomography Study in Treatment Resistant Depression
연구 개요
상태
정황
상세 설명
The first scan will take place before the first ECT session. The second scan will occur after a minimum of six ECT sessions (average 2.5 weeks). Secondary measures will include mood symptom severity, neurocognitive measures, peripheral inflammatory markers and TSPO genotype.
The hypothesis is that neuroinflammation will be increased by ECT.
There will be no alterations to standard care of depressed patients due to participation in the study.

ECT and Treatment Resistant Depression
Subjects will be those with diagnosis of major depressive disorder that have not responded to many different treatments and who are planning to take electroconvulsive therapy (ECT).
This group will receive two [18F]FEPPA PET scans, one baseline and one after an average of 2.5 weeks of ECT treatments.

17-item Hamilton Depression Rating Scale (HDRS)
기간: Baseline and after average 2.5 weeks of ECT treatment
|
Scores on the 17-item HDRS will be taken at the time of the PET scan (baseline and post-ECT) to assess whether the magnitude of change in TSPO distribution volume is associated with changes in symptom severity.
|
Baseline and after average 2.5 weeks of ECT treatment

Neurocognitive Battery
기간: Baseline and after average 2.5 to 5 weeks of ECT treatment
|
Neurocognitive measures will be take at baseline and post-ECT to assess whether TSPO Vt is related to neurocognitive function. Neurocognitive battery includes: Autobiographical Memory Interview-Short Form (AMI-SF) Rey Auditory Verbal Learning Test (RAVLT) Wisconsin Card Sorting Test Comprehensive Trail Making Test Weschler Adult Intelligence Scale-Digit Symbol Subtest Stroop Color and Word Test Brief Visuospatial Memory Test Boston Naming Test Judgement of Line Orientation Weschler Test of Adult Reading |
Baseline and after average 2.5 to 5 weeks of ECT treatment

|
Peripheral Inflammatory Markers
기간: Baseline and after average 2.5 to 5 weeks of ECT treatment
|
To explore whether peripheral and central inflammation are related markers of peripheral inflammation (TNF-alpha, IL-6, CRP and IL-1beta) will be measured and correlated to brain TSPO Vt.

Baseline and after average 2.5 to 5 weeks of ECT treatment
