1 Mani Pavuluri MD PhD Professor and Director Pediatric Brain Research and Intervention Center Berger-Colbeth Endowed Chair in Child Psychiatry

2 Focus of the Talk fmri Activity Studies fmri Treatment Studies fmri Connectivity Studies A Dimensional Model in Child Psychiatry

3 Reason to Investigate: Neurocognitive Function in PBD Pavuluri et al, 2006, Am J Psych

4 Longitudinal Study: Neurocognitive Problems Don t Go Away Pavuluri et al, 2009, JACAAP

5 fmri Activity Studies - Mapping the Real Estate in PBD Pavuluri and Sweeney, 2008 JAACAP

6 fmri Activity Studies

7 Fronto-limbic Affective Circuit TASK FINDING HC VPFC PBD DLPFC STG PBD-HC V1/V2 V1/V2 Amygdala OPERATION Euthymic unmedicated sample Pavuluri et al, 2006 Biol Psych

8 Face Response Circuit TASK FINDING DLPFC OFC Insula STS V1/V2 MTG OPERATION Euthymic unmedicated sample Pavuluri et al, 2006 Biol Psych

9 Pavuluri et al, 2009 JAACAP Occipito-Limbic Circuit (Reactive Circuit) TASK FINDING OPERATION Euthymic unmedicated sample

10 Pavuluri et al, 2008 Psych Neuroimage Interfacing Circuit TASK FINDING PBD HC PBD - HC OPERATION Euthymic unmedicated sample

11 Cognitive Circuit TASK FINDING LAMOTRIGINE IMPROVES FRONTO-STRIATAL ACTIVITY GO TRIAL STOP TRIAL OPERATION Unmedicated Sample at Baseline Pavuluri et al, 2010 J Clin Psych

12 fmri Treatment Studies

13 Lamotrigine Increases VLPFC Activity and Decreases Amygdala Activity TASK Keep in mind? Keep in working memory store ANGRY FACE CONDITION BASELINE ANGRY FACE CONDITION AT FOLLOW-UP VS. BASELINE (Based on task used in Passarotti et al., 2010) Passarotti et al, 2011 Psychopharmacology

14 DBRCT of Divalproex vs. Risperidone: Differential Activity During Affective Working Memory Paradigm Left VLPFC Left Ventral Striatum Pavuluri et al, 2010, ACNP

15 Pavuluri et al, in press Risperidone and Divalproex: Treatment Effects Risperidone: Responders vs. Non-responders Divalproex: Responders vs. Non-responders Amygdala Medial PFC Color matching Paradigm

16 fmri Connectivity Studies

17 Affective Working Memory Paradigm Passarotti et al, 2011 PBD Conference Affect Evaluation and Regulation Network Direct Comparison Between Groups (Two Sample t-test)

18 Passarotti et al, submitted Affect Evaluation and Regulation Network Between-Group Differences in activation in the Affect Evaluation and Regulation Network. Red indicates greater brain region engagement in PBD than in HC, blue indicates the opposite Group differences in ACC, VLPFC, amygdala and PHG Temporal correlation fit of BOLD fmri signal change to face emotion in PBD and in HC

19 Wegbreit et al, 2011 PBD Conference Functional Connectivity PBD and HC Over the Duration of Trial EVALUATIVE AFFECTIVE CIRCUIT REACTIVE AFFECTIVE CIRCUIT

20 Treatment Effects in Real-Time Divalproex Pre and Post Treatment Evaluative Affective Circuit Wegbreit et al, 2011 PBD Conference

21 Treatment Effects in Real-Time Risperidone Pre and Post Treatment Evaluative Affective Circuit Wegbreit et al, 2011 PBD Conference

22 Evaluative Affective Circuit Recruited During Response Inhibition Risperidone engaged left insula Divalproex engaged subgenual cingulate cortex Wegbreit et al, 2011, PBD conference

23 Risperidone and Divalproex: Reactive Affective Circuitry During Response Inhibition Amygdala is engaged poorly even after treatment Wegbreit et al, 2011, PBD conference

24 Amygdala Activity is More Engaged in Responders vs. Non-Responders Amygdala in Fronto-limbic Circuit Wegbreit et al, in progress
