OCD shows various abnormalities in cognitive function. Decision-making confidence is a burgeoning research focus on cognitive abnormality of OCD. Gamma-aminobutyric acid (GABA) is a type of inhibitory amino acid. Some studies have indicated that GABA shows metabolic abnormality in OCD.~Repetitive transcranial magnetic stimulation (rTMS) is a safe and noninvasive treatment for OCD. This study intends to explore the differences of the function-metabolism coupling in decision-making confidence neural network between OCD and HC. And investigating the dynamic changes of the function-metabolism coupling after rTMS treatment (6 weeks) for OCD is another goal.
This study, a case-control study, aims to investigate the function-metabolism coupling in decision-making confidence neural network of obsessive-compulsive disorder.
