Web15 May 2024 · Gilles de la Tourette syndrome (GTS) is a complex neurodevelopmental disorder characterized by tics and, frequently, psychiatric and behavioral comorbidities. Above all, obsessive compulsive disorder/behavior (OCD/OCB) influences the clinical picture and has a severe impact on quality of life, eventually more than the tics themselves. Deep … Web28 Jan 2024 · OCD is mediated by an imbalance between the direct (excitatory, OFC-striatum-globus pallidus-thalamus-cortical) and indirect (inhibitory, DLPFC-striatum-globus pallidus-subthalamic nucleus-cortical) pathways within this circuit, which causes a brain lock in the caudate nucleus and a mutual hyperactivation between the OFC and thalamus.
WebThese structures provide inhibitory tone to the thalamus, mediated by a balance of “accelerator- brake” activity through the direct and indirect pathways. 10 An imbalance in this system with increased activity in the direct pathway, would disinhibit the thalamus and promote repetitive behavioral sequences. 11 The most accepted model of pathogenesis … Web3 Oct 2024 · The thalamus plays an important role in pathological mechanisms underlying obsessive-compulsive disorder (OCD). As the thalamus is a heterogeneous brain region, functional connectivity (FC) between thalamic subregions and other brain regions is worth investigating in OCD. In addition, the relationship between abnormal FC and clinical …
