“…OCD is one of the most wide-spread psychiatric complications after stroke and traumatic brain injury [ 38 ]. Patients with Parkinson’s disease might demonstrate specific behavior called ‘punding’, which is complex, long-term, purposeless, stereotypic behavior that can be misidentified as an OCD sign [ 39 ]. In Sydenham’s chorea, it has been noted that practically all patients develop OCD symptoms at an early stage of the disease [ 40 ] due to an autoimmune response to streptococcal infection leading to inflammation in the basal ganglia — brain regions involved in the pathogenesis of OCD [ 41 ].…”

Multiple studies in patients with obsessive-compulsive disorder (OCD) became the basis for revealing selective attention, inhibitory control, and working memory impairments, which correlates with an imbalance in the activity of the cortico-striatal-thalamic-cortical circuit associated with maintenance of cognitive control functions. Patients with OCD often demonstrate changes in the parameters of target-oriented eye movement reactions being a consequence of a possible impairment of the cognitive control neurophysiological framework. This review summarizes and analyzes data on cognitive control disorders in OCD obtained with eye movement recording techniques. It was established that the most often used are smooth pursuit eye movements tasks, memory-guided saccades, and anti-saccadic tasks. Data on smooth pursuit eye movements tasks and memory-guided saccades are contradictory, although they partially confirm selective attention and working memory impairment. Most studies on the anti-saccadic task identified impaired inhibitory control in patients with OCD. Similar disorders in form of increased latency and higher error rate in anti-saccades were also noted in the patients’ first-degree relatives, which allows considering such disorders as manifestations of the endophenotype associated with the underlying risk of OCD. Future confirmation of these results in experiments using complex anti-saccadic tasks with images of various modalities (taking into account the increased anxiety in patients with OCD as the disorder basis) might contribute to validation of the OCD-specific markers.
