fMRI studies of error-processing in pediatric obsessive compulsive and anxiety disorders: a summary of the published literature
Study | Age (yrs) | Patient type | Design | Paradigm | Main results |
---|---|---|---|---|---|
Wooley et al., 200864 | 12–16 (boys only) | OCD | Group comparison: OCD (n = 10) v HC (n = 9) |
Stop Task | Decreased activation in mesial frontal gyrus, reaching laterally into left dorsolateral prefrontal cortex and ventrally into anterior cingulate gyrus in OCD compared to HC for Stop Failure minus Go trials. |
Fitzgerald et al., 201040 | 8–19 | OCD | Group comparison: OCD (n = 15) v HC (n = 12) |
MSIT | Increased activation in ventral medial prefrontal cortex in OCD compared to HC for error minus correct trials (across incongruent and congruent trials). |
Huyser et al., 201154 | 8–19 | OCD | Before/after CBT: OCD (n = 25/24) v HC (n = 25/22) |
Flanker (arrow) | Increased activation in anterior cingulate cortex and right insula at older ages in OCD compared to HC before and after treatment for error minus correct trials (across incongruent and congruent trials). |
Fitzgerald et al., 201363 | 8–19 | AD, OCD | Group comparison: OCD (n = 17), AD (n = 13) v HC (n = 20) |
MSIT | Decreased left dorsolateral prefrontal cortex in AD and OCD compared to HC for error minus correct trials (incongruent trials only). |
OCD = obsessive-compulsive disorder; AD = anxiety disorders including generalized anxiety disorder, separation anxiety disorder, social phobia and specific phobia; CBT = cognitive behavioral therapy; HC = healthy controls; MSIT = Multisource Interference Task.
