Aim Anterior capsulotomy (AC) is one of the last therapeutic options for obsessive–compulsive disorder (OCD) refractory to conservative treatments. Several forms of cognitive dysfunction have been identified after assessment of neuropsychological outcomes in OCD patients; however, few studies focused on cognitive changes in OCD patients after surgery. In the present study, we evaluated the effects of AC on cognitive performance and mood status in patients with refractory OCD. Methods A total of 12 patients underwent bilateral AC between 2012 and 2019 at our institution. The patients (n = 12, female : male 5:7; mean age 39.7 years; duration ≥5 years) were assessed before and 6 months after intervention. The diagnosis of treatment‐refractory OCD was based on recommended criteria for surgical treatment. Patients were assessed using a neuropsychological battery and questionnaires focused on anxiety–depressive symptomatology. The Yale–Brown Obsessive Compulsive Scale was administered as a measure of severity of OCD symptoms. Results We detected a significant decrease of OCD, and anxiety and depressive symptomatology assessed by Yale–Brown Obsessive Compulsive Scale, Beck Depression Inventory, and Beck Anxiety Inventory (P < 0.05) 6 months after AC in eight patients, and a partial decrease in four patients. Four patients underwent repeated AC with more pronounced improvement achieved after the first procedure. We did not detect decline in cognitive performance in any patients, but did find better visual memory performance (P < 0.05). Conclusion AC reduced OCD and anxiety–depressive symptoms, and did not appear to influence cognitive performance, even after repeated surgery.

The term PNES refers to a conversion disorder that mimics epileptic seizures but has a psychological etiology. Recent studies report that in patients with PNES, there is reduced understanding of emotions, impulse control difficulties, and limited access to emotional regulation strategies. The aim of this study was to compare patients diagnosed with PNES with healthy volunteers on the presence of maladaptive emotional regulation. Method: Patients (N = 64 F:M 52:12; mean age 35.5 years; duration ≥ 2 years) were assessed while inpatients at the Epilepsy Center, Na Homolce Hospital, Prague. PNES diagnosis was based on normal EEG findings, habitual seizure capture, suggestive seizure provocation, neuropsychological assessment and patients´history. The clinical sample was compared with healthy volunteers (N = 64 F:M 52:12; mean age 35.8 years). The presence of maladaptive emotional regulation was assessed through the Czech research version of the ASQ and DERS. Results: Compared with a healthy sample, patients with PNES had greater emotion regulation impairments across nearly all dimensions of the DERS -Nonacceptance = 17.0 (M = 14.5), p = 0.006, Goals = 16.0 (M = 11.5), p < 0.001, Impulse control = 13.8 (M = 11.5), p = 0.005, Awareness = 16.4 (M = 15.3), p = 0.183, Strategies = 17.9 (M = 13.0), p < 0.001, Clarity = 11.8 (M = 9.5), p < 0.001 and the total score of the DERS = 92.9 (M = 75.3), p < 0.001. Similar results were found in ASQ questionnaire scales -Concealing = 24.5 (M = 21.0), p = 0.002, and Adjusting = 20.9 (M = 22.8), p = 0.076 but not on the Tolerating Scale = 14.5 (M = 14.7), p = 0.873. Conclusion:Our results highlight that maladaptive emotional regulation is a key psychological mechanism in PNES. Emotional dysregulation may represent an important target when designing psychoeducational and psychotherapeutic approaches for patients with PNES.

Background: Internal carotid endarterectomy (CEA) is a method of stroke prevention in patients with severe internal carotid artery (ICA) stenosis. Patients with significant carotid stenosis tend to have lower cognitive performance than those without significant stenosis. This is believed to be due to hypoperfusion or ongoing microembolization to the brain. Methods: We evaluated 60 patients with at least 70% ICA stenosis with the RBANS test (Repeatable Battery for the Assessment of Neuropsychological Status, Czech research version), preoperatively and one month a ter endarterectomy. Results: Neuropsychological follow-up was completed by N = 57 patients one month after the procedure. At the group level, there was a significant improvement in Language, Attention, Delayed Memory and Total Scale Index Scores (p < 0.05). Conclusions: CEA not only decreases the long-term risk of ischemic stroke, but may also improve cognitive performance. In a small percentage of cases, there is higher risk of embolic stroke and silent microembolization due to surgery, which may have a negative impact on cognitive function. However, we did not detect any cognitive impairment a ter CEA in our patients.

The aim of the study was to examine the neuropsychological performance and effort in patients with a confirmed PNES diagnosis. The second aim of the study was to investigate the relationship between validity indicators from the cognitive battery with validity and clinical scales from a personality scale. Method: Patients with PNES (N = 250; F:M 186:64; mean age 38.32 (13.23)) were assessed utilizing the RBANS (Czech Research version) to evaluate cognitive performance and to obtain the Effort Index. The MMPI-2 was used to evaluate personality and psychopathology. Results: Global cognitive performance was 0.92 SD below average (according to the Gaussian distribution) in patients with PNES. The lowest scores in the sample were in the Attention domain (À1.7SD). Insufficient effort was detected in 10% of patients. Education correlated negatively with the Effort index (rs = À0.25, p = 0.01). A mild significant correlation in Scale 7 (rs = 0.21, p = 0.01) and Scale 8 (rs = 0.24, p = 0.01), and a significant correlation between Effort Index and Back F Scale (rs = 0.23, p = 0.01) were noted. Conclusions: Assessment of cognitive performance and effort is an essential part of the comprehensive evaluation of patients with PNES during their hospitalization at Epilepsy centers. Many aspects of the neuropsychological assessment can offer useful indications for reaching a differential diagnosis, including clinical history, behavioral observations, cognitive and symptom validity testing, and structured psychological inventories.

To delineate sociodemographic data of a large sample of Czech Republic patients diagnosed with psychogenic non-epileptic seizures (PNES) at the time of diagnosis and at a follow-up visit one year after discharge.This study collected reports of past stressors, quality of relationships in childhood, family background, traumatic events, and recent adversities in patients diagnosed with PNES. Method: Patients (219w/79m, 37.56 (13.15) years, 12.13 (2.05) years of education) were assessed through a semi-structured interview on clinical and historical data while they were inpatients at the Epilepsy Center, Na Homolce Hospital, Prague. Subsequently, they were re-evaluated one year after discharge from the hospital with the same method. A comparison of this sample to normal controls was subsequently conducted. Results: We found a higher female (73.5%) predominance; mean duration of seizures was 69.14 months. The majority of patients were single (46.13%) or divorced (16.84%), and 48% received disability benefits. A diversity of developmental risk factors as well as immediate precursors of PNES onset were identified. One year after hospitalization, significant changes were found in all seizure and healthcare characteristics of our sample. When compared to healthy volunteers, the patients also presented with a higher prevalence of stressors and traumatic events in childhood. Conclusions: Cross-cultural research contributes important information on the universal components of PNES as well as the unique features observed in distinct localities of differing cultures and ethnicities. This study allows for comparison of sociodemographic features in a Central European sample to the more frequently studied English-speaking samples.
