The Effect of Antidepressant Treatment on Neurocognitive Functions, Redox and Inflammatory Parameters in the Context of COVID-19. J Clin Med 2023; 12:7049. [PMID: 38002663 PMCID: PMC10671940 DOI: 10.3390/jcm12227049] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 09/25/2023] [Revised: 11/08/2023] [Accepted: 11/09/2023] [Indexed: 11/26/2023] Open
Abstract
Inflammation is an important component of the etiopathology of depression that uses oxidative and nitrosative stress (O&NS) and elevated inflammatory markers. SARS-CoV-2 infection is also associated with abnormal inflammatory processes, which may impair effective treatment of depression in COVID-19 survivors. In the presented study, thirty-three hospitalized patients with major depressive disorder (MDD) were started on antidepressant treatment, and twenty-one were re-evaluated after 4-6 weeks. The control group consisted of thirty healthy volunteers. All participants underwent neuropsychiatric evaluation, biochemical blood and urine analyses. The results of the research demonstrated positive correlations of the Hamilton Depression Rating Scale (HAM-D) scores with serum catalase (CAT) and urinary S-Nitrosothiols levels, and the Beck Depression Inventory (BDI) scores with serum reduced glutathione (GSH) and superoxide dismutase (SOD) levels. Depressed patients with a history of COVID-19 prior to the treatment had higher urinary nitric oxide (NO) levels and lower serum glutathione peroxidase (GPx) levels. In the control group, COVID-19 survivors had higher levels of urinary N-formylkynurenine (NFK). Our results suggest that the antidepressant treatment has a modulating effect on O&NS, reduces depressive symptoms and improves cognitive functions The present study does not indicate that clinical response to antidepressant treatment is associated with COVID-19 history and baseline SARS-CoV-2 antibody levels. Nevertheless, further research in this area is needed to systematize antidepressant treatment in COVID-19 survivors.

Skull progenitor cell-driven meningeal lymphatic restoration improves neurocognitive functions in craniosynostosis. Cell Stem Cell 2023; 30:1472-1485.e7. [PMID: 37863055 PMCID: PMC10842404 DOI: 10.1016/j.stem.2023.09.012] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 04/06/2023] [Revised: 08/21/2023] [Accepted: 09/27/2023] [Indexed: 10/22/2023]
Abstract
The meninges lie in the interface between the skull and brain, harboring lymphatic vasculature and skull progenitor cells (SPCs). How the skull and brain communicate remains largely unknown. We found that impaired meningeal lymphatics and brain perfusion drive neurocognitive defects in Twist1+/- mice, an animal model of craniosynostosis recapitulating human Saethre-Chotzen syndrome. Loss of SPCs leads to skull deformities and elevated intracranial pressure (ICP), whereas transplanting SPCs back into mutant mice mitigates lymphatic and brain defects through two mechanisms: (1) decreasing elevated ICP by skull correction and (2) promoting the growth and migration of lymphatic endothelial cells (LECs) via SPC-secreted vascular endothelial growth factor-C (VEGF-C). Treating Twist1+/- mice with VEGF-C promotes meningeal lymphatic growth and rescues defects in ICP, brain perfusion, and neurocognitive functions. Thus, the skull functionally integrates with the brain via meningeal lymphatics, which is impaired in craniosynostosis and can be restored by SPC-driven lymphatic activation via VEGF-C.

Comparative effectiveness of aripiprazole and olanzapine on neurocognitive profile of patients with schizophrenia. Indian J Psychiatry 2023; 65:1044-1051. [PMID: 38108052 PMCID: PMC10725211 DOI: 10.4103/indianjpsychiatry.indianjpsychiatry_303_23] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Figures] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 04/27/2023] [Revised: 08/04/2023] [Accepted: 08/30/2023] [Indexed: 12/19/2023] Open
Abstract
Background Schizophrenia causes significant neurocognitive impairment. Treatment with antipsychotics leads to improvement in psychopathology and neurocognitive functions. Aim To see comparative effectiveness of aripiprazole and olanzapine on neurocognitive profile of patients with schizophrenia. Materials and Methods This was a comparative, prospective, and interventional study. Patients with schizophrenia as per the Diagnostic and Statistical Manual of Mental Disorders, Fifth Edition (DSM-5), were assessed on Brief Psychiatric Rating Scale (BPRS), Positive and Negative Syndrome Scale (PANSS), and neuropsychological tests at baseline. Patients were randomly assigned to aripiprazole (10-30 mg per day, orally) and olanzapine (5-20 mg per day, orally) groups on the basis of computer-generated random table number. Patients were reassessed at 10 weeks. Results A total of 40 patients completed the study duration of 10 weeks. At baseline, the majority of patients showed significant impairment in one or more domains of neurocognition. Both aripiprazole and olanzapine led to improvement in psychiatric symptoms as well as neurocognitive profile. Aripiprazole treatment leads to significant improvement in mental speed as compared to olanzapine. A highly significant decrease in the value of the Stroop effect indicates improvement (P = 0.000**) with aripiprazole and visual-spatial constructive ability (P < 0.001). The olanzapine group showed highly significant improvement in performance of category fluency (P < 0.01) and verbal fluency (P < 0.01). Conclusion The study concludes that aripiprazole and olanzapine have strong potential to improve specific domains of neurocognitive profile.

Abstract
Studies have demonstrated an association between CHD and neurodevelopmental delay. This delay is associated with many factors like reduced blood flow and oxygen, cardiac catheterisations, and genetic factors. Apo E gene polymorphism is one of these genetic factors. This study aims to show the effect of Apo E gene polymorphism on neurodevelopmental process in children having CHD. A total of 188 children having CHD were admitted to the study. Apo E gene polymorphism of these patients was determined, and psychometric evaluation was performed. The relationship between psychometric test results and gene polymorphism was evaluated. This study shows that, similar to the literature, patients having cyanotic CHD have worse scores than acyanotic patients, and the children with CHD are under risk in terms of neuropsychiatric disorders. Other novel and important findings of this study were the lower verbal scores of ε2 allele carriers than ε4 carriers in Wechsler Intelligence Scale for Children-Revised group and the worse test score of patients having VSD than other acyanotic patients. Besides, some special disorders may be seen in this patient group.

Proposal of a common terminology for the neuropsychological rehabilitation. J Neuropsychol 2023; 17:431-449. [PMID: 36891955 DOI: 10.1111/jnp.12310] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 12/08/2022] [Revised: 02/03/2023] [Accepted: 02/16/2023] [Indexed: 03/10/2023]
Abstract
The literature on neuropsychological intervention (NI) uses a variety of terms to refer to equivalent constructs, making it difficult to compare intervention programmes and their outcomes. The purpose of this work is to propose a unified terminological framework for describing NI programmes. The terminological framework was developed based on a previous proposal for common terminology by Johnstone and Stonnington (Rehabilitation of neuropsychological disorders: A practical guide for rehabilitation professionals. Psychology Press, 2011) and driven by Cognitive Psychology concepts. The terminological framework was organized into two sections: (a) NI, which includes types of NI, methods and approaches, instructional methods, and strategies; and (b) neurocognitive functions, which include temporal and spatial orientation, sensation, perception, visuo-constructional abilities, attention, memory, language, reasoning of several sorts (e.g., abstract reasoning, and numerical reasoning), and executive functions. Most NI tasks target a main neurocognitive function, but there are underlying neurocognitive functions that may impair performance in the former. Since it is difficult to create a task that is solely focused on one neurocognitive function, the proposed terminology should not be viewed as a taxonomy, but rather as dimensional, with the same task allowing to work different functions, in varying grades. Adopting this terminological framework will allow to define the targeted neurocognitive functions more accurately and simplify the comparison between NI programmes and their outcomes. Future research should focus on describing the main techniques/strategies for each neurocognitive function and non-cognitive interventions.

Abstract
BACKGROUND Major depressive disorder (MDD) is a significant cause of workforce loss, and is associated with cognitive impairments which can continue even after the elimination of mood and behavioural symptoms. The aim of this study was to investigate the benefit of transcranial magnetic stimulation (TMS) on cognitive functions in treatment resistant depression. METHODS This randomised controlled clinical trial was conducted at a university hospital, department of psychiatry (tertiary centre) between October 2019 and July 2020. The study included 30 patients with depressive disorder, aged 18-50 years, who did not respond to at least two antidepressant medications for at least 8 weeks (one drug used was serotonin norepinephrine reuptake inhibitor [SNRI]; and 15 healthy control subjects. The patients were separated into two equal groups in a double-blind, random manner, and 20 sessions of repeated TMS was applied to one group, and 20 sessions of sham TMS to the other. The Montgomery Asberg Depression Scale (MADRS), Hamilton Depression Rating Scale (HAM-D), Stroop test, Wisconsin Card Sorting Test (WCST), Digit Span Test (DST), Trail Making Test A-B, and Verbal Memory Processes Test (VMPT) were applied to the patients before and after the TMS procedure. RESULTS The decrease in the HAM-D score was greater in the active magnetic stimulation (25 trains, 10 Hz, 110% motor threshold intensity) group, and with the exception of verbal memory processes, better performance was obtained by the active magnetic stimulation group than the sham group in the cognitive function tests. DISCUSSION TMS was seen toimprove the cognitive defects present in the active phase of treatment-resistant depression, and therefore TMS could provide early improvement in cognitive functions in clinical use. Key words: Depression, transcranial magnetic stimulation, neurocognitive functi.

Developmental Milestones of Infancy and Associations with Later Childhood Neurodevelopmental Outcomes in the Adolescent Brain Cognitive Development (ABCD) Study. CHILDREN (BASEL, SWITZERLAND) 2022; 9:children9101424.

Abstract
The age at attaining infancy developmental milestones has been associated with later neurodevelopmental outcomes, but evidence from large and diverse samples is lacking. We investigated this by analyzing data of 5360 singleton children aged 9-10 from 17 states in the US enrolled in the Adolescent Brain Cognitive Development (ABCD) study during 2016-2020. Delays in four milestones (first roll over, unaided sitting, unaided walking, and speaking first words) were defined using the 90th percentile of age at attainment reported by children's biological mothers. Childhood neurocognitive function was measured by research assistants using the NIH toolbox, and children reported their behavioral problems using the Brief Problem Monitor. Linear mixed-effects models were employed to investigate the association between delays in single or multiple milestones and childhood neurobehavioral outcomes. Delays in first roll over, unaided sitting, or walking were associated with poorer childhood neurocognitive function, while delay in speaking first words was associated with both poorer neurocognitive function and behavioral problems. Children who had delays in both motor and language milestones had the worst neurocognitive function and behavioral outcomes. Our results suggest that delays in motor and language milestone attainment during infancy are predictive of childhood neurobehavioral outcomes.

Neuropsychological performances in patients with infiltrative non-GBM gliomas after postoperative adjuvant photon or proton radiotherapy: A prospective and preliminary investigation. APPLIED NEUROPSYCHOLOGY. ADULT 2022:1-10.

Abstract
Infiltrative non-GBM gliomas are common primary intracranial malignancies, and postoperative adjuvant radiotherapy is recommended for most adult patients diagnosed with this disease to enhance local control and prolong intracranial progression-free survival (PFS). However, RT-related neurocognitive function (NCF) consequences should not be ignored. Early neurocognitive decline principally includes episodic memory, associated significantly with functions of the hippocampus. This prospective study aims to investigate the impact of adjuvant brain irradiation on neurocognitive performances and relevant oncological outcomes.Twenty-five patients with intracranial infiltrative non-GBM gliomas were enrolled when postoperative adjuvant RT was recommended. All recruited patients should receive baseline brain magnetic resonance imaging, and neuropsychological assessments before and 4 months after the RT course. A battery of neuropsychological measures, mainly including executive functions, memory, psychomotor speed and visuoconstructive ability, was used to evaluate NCFs of interest.Analyzing the delta values between post-irradiation and baseline NCF scores, we observed a robust trend reflecting cognitive stabilization rather than deterioration in almost all NCF. Both verbal and visual memory functions exhibited significant differences in the corresponding scaled scores (Z = -2.722, p = .006, regarding verbal memory; Z = -2.246, p = .025, concerning non-verbal memory). Moreover, patients' neuropsychological performances associated with psychomotor speed and executive functions also disclosed a tendency toward stabilization/improvement.This prospective study demonstrated that patients with infiltrative non-GBM exhibited a marked tendency toward neurocognitive stabilization after receiving postoperative adjuvant RT.

Abstract
There is a growing evidence describing a decline in adaptive homeostasis in aging-related diseases affecting the central nervous system (CNS), many of which are characterized by the appearance of non-native protein aggregates. One signaling pathway that allows cell adaptation is the integrated stress response (ISR), which senses stress stimuli through four kinases. ISR activation promotes translational arrest through the phosphorylation of the eukaryotic translation initiation factor 2 alpha (eIF2α) and the induction of a gene expression program to restore cellular homeostasis. However, depending on the stimulus, ISR can also induce cell death. One of the ISR sensors is the double-stranded RNA-dependent protein kinase [protein kinase R (PKR)], initially described as a viral infection sensor, and now a growing evidence supports a role for PKR on CNS physiology. PKR has been largely involved in the Alzheimer’s disease (AD) pathological process. Here, we reviewed the antecedents supporting the role of PKR on the efficiency of synaptic transmission and cognition. Then, we review PKR’s contribution to AD and discuss the possible participation of PKR as a player in the neurodegenerative process involved in aging-related pathologies affecting the CNS.

Abstract
Introduction Bipolar disorder (BD) and attention deficit hyperactivity disorder (ADHD) often co-occur in adult population. Both conditions present various neurocognitive and behavioral problems. We aimed to examine neurocognitive functions in adult patients with comorbid BD and ADHD (BD+ADHD) in comparison to patients with only BD, only ADHD and healthy controls (HCs). Method An extensive cognitive battery which evaluates verbal learning and memory, visual memory, processing speed, attention, executive functions, working memory and verbal fluency, was used to assess neurocognitive functions respectively in adult (age 18-65 years) patients with BD (n=37), ADHD (n=43), BD+ADHD (n=20) in comparison to HCs (n=51). The Multivariate Analysis of Covariance models, where age, level of education and total BIS-11 scores were included as covariates, were used for comparing neurocognitive scores among groups. Results Both BD and BD+ADHD groups showed significantly poorer performance than HCs in processing speed, attention, executive functions, and verbal fluency domains. The BD group had additional significant deficits in executive functions, verbal learning and memory domains. There were no significant differences between BD and BD+ADHD groups with regards to verbal learning and memory, visual memory, processing speed, attention, executive functions, working memory and verbal fluency domains. Patients with only ADHD showed significantly poorer performance than HCs in verbal fluency domain. Conclusions Our results show similarities in the neurocognitive functions of adults with BD and BD+ADHD across a wide range of cognitive domains. The findings point to the need for further exploration of diverging and converging neurodevelopmental trajectories of BD and ADHD.

Abstract
PURPOSE The aim of this study was to analyze neurocognitive function in patients who underwent continuous flow left ventricular assist device (LVAD) implantation. MATERIAL AND METHOD This cross-sectional study included three groups: LVAD (n = 31), heart failure patients (n = 26), and healthy volunteers (n = 27). The Rey Auditory-Verbal Learning Test (RAVLT), Judgement of Line Orientation Test (JLOT), Trail Making Test (TMT), Stroop Color-Word Interference Test (SCWIT), Verbal Fluency Test (VFT), Symbol-Digit Modality Test (SDMT) were used to assess the neurocognitive functions. Data were analyzed at a median 12 (3-47) months after LVAD implantation. The LVAD patients were also divided by aortic valve opening (AVO) into three subgroups as "closed" (n = 9), "1-6" (n = 8) and "7-10" (n = 14) opening per ten beats and data were re-analyzed accordingly. RESULTS There was no significant difference among the groups according to SCWIT, JLOT, SDMT, TMT, and VFT scores. Post-hoc analyzes of RAVLT scores showed significant differences between the LVAD and the other two groups in favor of the LVAD group. Also, the patients with AVO "7-10" the response times were longer and learning scores were found to be lower than those without AVO. CONCLUSION With continuous-flow LVAD, neurocognitive functions were not impaired. The learning performance was better in cases where there was no AVO and flow was completely device dependent. We may speculate that neurocognitive functions are not worsening with continuous cerebral blood flow and even it may improve learning performance.

Chronic Sodium Selenate Treatment Restores Deficits in Cognition and Synaptic Plasticity in a Murine Model of Tauopathy. Front Mol Neurosci 2020; 13:570223.

Abstract
A major goal in diseases is identifying a potential therapeutic agent that is cost-effective and can remedy some, if not all, disease symptoms. In Alzheimer’s disease (AD), aggregation of hyperphosphorylated tau protein is one of the neuropathological hallmarks, and Tau pathology correlates better with cognitive impairments in AD patients than amyloid-β load, supporting a key role of tau-related mechanisms. Selenium is a non-metallic trace element that is incorporated in the brain into selenoproteins. Chronic treatment with sodium selenate, a non-toxic selenium compound, was recently reported to rescue behavioral phenotypes in tau mouse models. Here, we focused on the effects of chronic selenate application on synaptic transmission and synaptic plasticity in THY-Tau22 mice, a transgenic animal model of tauopathies. Three months with a supplement of sodium selenate in the drinking water (12 μg/ml) restored not only impaired neurocognitive functions but also rescued long-term depression (LTD), a major form of synaptic plasticity. Furthermore, selenate reduced the inactive demethylated catalytic subunit of protein phosphatase 2A (PP2A) in THY-Tau22 without affecting total PP2A.Our study provides evidence that chronic dietary selenate rescues functional synaptic deficits of tauopathy and identifies activation of PP2A as the putative mechanism.

Abstract
OBJECTIVE Lower-grade gliomas (LGGs) are often observed within eloquent regions, which indicates that tumor resection in these areas carries a potential risk for neurological disturbances, such as motor deficit, language disorder, and/or neurocognitive impairments. Some patients with frontal tumors exhibit severe impairments of neurocognitive function, including working memory and spatial awareness, after tumor removal. The aim of this study was to investigate neurocognitive and functional outcomes of frontal LGGs in both the dominant and nondominant hemispheres after awake brain mapping. METHODS Data from 50 consecutive patients with diffuse frontal LGGs in the dominant and nondominant hemispheres who underwent awake brain surgery between December 2012 and September 2018 were retrospectively analyzed. The goal was to map neurocognitive functions such as working memory by using working memory tasks, including digit span testing and N-back tasks. RESULTS Due to awake language mapping, the frontal aslant tract was frequently identified as a functional boundary in patients with left superior frontal gyrus tumors (76.5%). Furthermore, functional boundaries were identified while evaluating verbal and spatial working memory function by stimulating the dorsolateral prefrontal cortex using the digit span and visual N-back tasks in patients with right superior frontal gyrus tumors (7.1%). Comparing the preoperative and postoperative neuropsychological assessments from the Wechsler Adult Intelligence Scale-Third Edition (WAIS-III) and Wechsler Memory Scale-Revised (WMS-R), significant improvement following awake surgery was observed in mean Perceptual Organization (Z = -2.09, p = 0.04) in WAIS-III scores. Postoperative mean WMS-R scores for Visual Memory (Z = -2.12, p = 0.03) and Delayed Recall (Z = -1.98, p = 0.04) were significantly improved compared with preoperative values for every test after awake surgery. No significant deterioration was noted with regard to neurocognitive functions in a comprehensive neuropsychological test battery. In the postoperative course, early transient speech and motor disturbances were observed in 30.0% and 28.0% of patients, respectively. In contrast, late permanent speech and motor disturbances were observed in 0% and 4.0%, respectively. CONCLUSIONS It is noteworthy that no significant postoperative deterioration was identified compared with preoperative status in a comprehensive neuropsychological assessment. The results demonstrated that awake functional mapping enabled favorable neurocognitive and functional outcomes after surgery in patients with diffuse frontal LGGs.

Abstract
Proton Beam Therapy (PBT) was developed to minimize the harmful results of radiation therapy as treatment for brain tumors. This study examined the neurocognitive outcomes of PBT in pediatric patients. A total of 8 patients, who received either PBT or photon radiotherapy (XRT), were evaluated with multiple cognitive functions, which include intelligence, memory, executive functions, and attention. Most of patients performed average-to-superior levels of neurocognitive functions (NCF), except that a deterioration of executive functions was revealed in two patients receiving XRT. This study might be the first one to show the maintenance of multidomain NCF after PBT.

Abstract
OBJECTIVE Aneurysmal subarachnoid haemorrhage (SAH) may have devastating effects on patients. Motor and neurocognitive impairments may arise depending on the location and grade of the SAH. Although the effects of amantadine on neurocognitive function after traumatic brain injury have been widely studied to the best of our knowledge, their effects on recovery from SAH in humans have not been studied. The present study aimed to evaluate how amantadine influences improvement in neurocognitive function in patients with aneurysmal SAH over a period of six months. METHODS This preliminary study included 12 patients with aneurysmal SAH who were admitted to the neurointensive care unit of Cerrahpasa Faculty of Medicine. Patients in Group A (n=5) received the standard treatment for SAH and amantadine for 30 days after admission, and those in Group C (n=7) received only the standard treatment. Neurocognitive function was evaluated using the Coma Recovery Scale-Revised and Disability Rating Scale on the first and fifth days and at the third and sixth months after admission. The primary endpoint of the present study was to compare the effects of amantadine in combination with the standard treatment to those of the standard treatment alone on the neurocognitive function of patients with SAH for over 6 months. RESULTS Compared to the standard treatment alone, amantadine administration with the standard treatment during the early period of SAH may improve recovery. CONCLUSION Amantadine along with the standard treatment can ameliorate neurocognitive function after SAH.

Abstract
OBJECTIVE Inflammation is an important factor in pathophysiology of bipolar disorder. Neutrophil-lymphocyte ratio (NLR) and platelet-lymphocyte ratio (PLR) analysis are used to predict peripheral inflammation. The aim of this study is to calculate neutrophil-lymphocyte and platelet-lymphocyte ratios, which are inflammatory markers, and investigate their effect on cognitive functions in euthymic patients with objective bipolar disorder. METHOD Twenty - eight patients with type-I bipolar disorder and 22 healthy controls matched for age, gender and educational status were included in the study. Neuropsychological tests were applied to all participants. Neutrophils, lymphocytes and platelets counts of the participants were measured and NLR and PLR were calculated. RESULTS There was a significant negative correlation between NLR and Stroop interference score in study group. There was no statistically significant difference in NLR and PLR between study and control group. No significant correlation was found between PLR and neurocognitive test scores. CONCLUSION This study revealed negative correlation between NLR and Stroop interference scores. We need further prospective studies with larger sample size to investigate role of inflammation on cognitive functions.

Abstract
UNLABELLED The aim of study was to evaluate an influence of recurrent syncope episodes on the neurocognitive functions (NCF) in patients with suspected VVS. AIM The aim of study was to evaluate an influence of recurrent syncope episodes on the neurocognitive functions (NCF) in patients with suspected VVS. MATERIALS AND METHODS Study population: 24 pts. (16 women) aged 17-70 yrs (mean age 40 years), with suspected VVS, referred to HUTT (head-up tilt test). All pts. underwent initial evaluation regarding to the number and circumstances of the syncopal and/or presyncopal spells. All pts performed HUTT with Westminster protocol. Basing on the syncope history and HUTT results, two groups of pts were distinguished: gr. I - 18 pts with at least 2 syncopal spells and positive HUTT, and gr. II 6 pts with only presyncopal status without complete loss of consciousness and negative HUTT. All pts underwent the evaluation of NCF with computer-assisted Vienna Test System battery, consisted of the following tests: DAUF - evaluation of long-term selective attention and concentration; COG - assessment of attention and concentration; STROOP - registration of the color-word interference tendency, CORSI - estimation of visual short-term memory capacity and implicite visuo-spatial learning. Values of the measured parameters were compared between both groups of pts. RESULTS Patients without syncope (gr. II) had higher number of correctly reproduced sequences (11,0 vs 8,38 p<0,01) and Reliable Spatial Span score (5,50 vs 4,46,p<0,02) in CORSI test, in relation to pts with syncope history (gr. I). This suggests possible influence of the recurrent syncope episodes on the short-term memory capacity in pts with VVS. There were no significant differences between groups, comparing results of the other tests. CONCLUSIONS Repeated syncope episodes may lead to impairment of short-term memory capacity in patients with vasovagal syndrome. Syncope episodes may have potentially negative influence on neurocognitive functions in patients with vasovagal syndrome.

Abstract
Pediatric obstructive sleep apnea (OSA) is associated with chronic systemic inflammation and with cognitive impairments. This study aimed to investigate the status of proinflammatory cytokines, particularly interleukin 17 (IL-17) and interleukin 23 (IL-23) and cognition in pediatric OSA.Controls and OSA children participated in the study. Exclusion criteria were adenotonsillectomy, heart, neurological and severe psychiatric diseases, craniofacial syndromes, and obesity. Polysomnogram was followed by serum testing for inflammatory markers and neurocognitive tests such as continuous performance task (CPT) and Wisconsin card sorting test, questionnaires, analyses of plasma high-sensitivity C-reactive protein (HS-CRP), tumor necrosis factor alpha (TNF-α), interleukin 1 (IL-1), interleukin 6 (IL-6), IL-17, and IL-23.Seventy-nine, 4 to 12-year-old subjects in 2 groups ended the study: 47 nonobese OSA children (mean age = 7.84 ± 0.56 years, body mass index [BMI] = 16.95 ± 0.47 kg/m, BMI z-score = 0.15 ± 0.21, and mean apnea-hypopnea index [AHI] = 9.13 ± 1.67 events/h) and 32 healthy control children (mean age = 7.02 ± 0.65 years, with BMI = 16.55 ± 0.58 kg/m, BMI z-score = -0.12 ± 0.27, and mean AHI = 0.41 ± 0.07 event/h) were enrolled. Serum cytokine analyses showed significantly higher levels of HS-CRP, IL-17, and IL-23 in OSA children (P = 0.002, P = 0.024, and P = 0.047). Regression test showed significant influence of HS-CRP, TNF-α, IL-6, IL-17, and specifically IL-23, with the continuous performance test and Wisconsin card sorting test.OSA children have abnormal levels of IL-17, an interleukin related to T helper 17 cells, a T helper cell involved in development of autoimmunity and inflammation. This high expression level may contribute to the complications of pediatric OSA; we also found a significant influence of inflammatory cytokines, particularly IL-23, on abnormal neurocognitive testing.

Abstract
The maintenance of quality of life in patients with high-grade glioma is an important endpoint during treatment, particularly in those with glioblastoma multiforme, given its dismal prognosis; thus, the primary aims of treatments are to reduce morbidity, restore or preserve neurological functions, and the capacity to perform daily activities. This review aims to summarise what is currently known about neurocognitive outcome and quality of life in patients with high-grade glioma, particularly in glioblastoma patients. We considered all the variables that can influence neurocognitive functions, the perception of quality of life and their role as predictors for treatment outcomes.

Neurocognitive predictors of substance use disorders and nicotine dependence in ADHD probands, their unaffected siblings, and controls: a 4-year prospective follow-up. J Child Psychol Psychiatry 2015; 56:521-9.

Abstract
BACKGROUND Attention-Deficit/Hyperactivity Disorder (ADHD) is a risk factor for substance use disorders (SUDs) and nicotine dependence (ND). Neurocognitive deficits may predict the increased risk of developing SUDs and nicotine dependence. METHODS This study comprised three groups derived from the Dutch part of the International Multicenter ADHD Genetics (IMAGE) study: ADHD probands (n = 294), unaffected siblings (n = 161), and controls (n = 214). At baseline (age = 12.2), a range of neurocognitive functions was assessed including executive functions (inhibition, working memory, timing), measures of motor functioning (motor timing and tracking) and IQ. After a mean follow-up of 4.2 years, SUDs and ND were assessed. RESULTS None of the neurocognitive functions predicted later SUDs or ND in ADHD probands, even after controlling for medication use and conduct disorder. Slower response inhibition predicted later nicotine dependence in unaffected siblings (OR = 2.06, 95% CI = 1.22-3.48), and lower IQ predicted increased risk for SUDs in controls (OR = 1.96, 95% CI = 1.12-3.44). CONCLUSIONS Cold executive functions, motor functioning, and IQ did not predict the elevated risk of SUDs and ND in ADHD. Future studies should target 'hot' executive functions such as reward processing as risk factors for SUDs or ND.

Abstract
In this study, we examined whether topologic network analysis, using resting state functional magnetic resonance imaging (MRI), can detect abnormalities of functional brain connectivity in children with unilateral brain injury due to Sturge-Weber syndrome. Three children with Sturge-Weber syndrome (ages 1, 3, and 10 years) underwent structural and resting state functional MRI, glucose metabolism positron emission tomography (PET), and neurocognitive evaluation. Eight different resting state networks were compared between the affected and unaffected hemispheres by quantitatively accessing communication efficiency measures. Significantly reduced efficiency values were found in all 3 patients. Visual network deficiency was present in both children with a visual field defect; frontal network abnormalities were associated with fine motor impairment. Location of network abnormalities corresponded to and, in some cases, extended beyond structural MRI and glucose PET abnormalities. The presented approach can detect early functional abnormalities of specific brain networks in children with Sturge-Weber syndrome.

Abstract
BACKGROUND The notable survival chances of intracranial germ cell tumors (icGCTs) lead to a rising concern over long-term neurocognitive outcome. Yet, prior evidence related to this issue fails to provide a comprehensive examination of the effects of tumor location and radiotherapy. We attempt to explore their impacts on the neuropsychological functions and life quality in children with icGCT after multimodality treatments. METHODS A retrospective review of 56 patients diagnosed with icGCTs at age <20 and treated at the Taipei Veterans General Hospital was provided. Intelligence, memory, visual organization, attention, and executive function were assessed by neurocognitive tests; adaptation to life, emotional and behavioral changes, interpersonal relationships, and impact on the family were evaluated by parent-report instruments. Effects of tumor locations (germinomas and nongerminomatous malignant germ cell tumors in the pineal, suprasellar, and basal ganglia) and irradiation on these measurements were examined. RESULTS Patients with tumors in the basal ganglia region had lower full-scale IQs than those with tumors in the pineal or suprasellar regions. Subscores of intelligence scale and short-term retention of verbal and visual stimuli showed evident group differences, as did the quality of life and adaptive skills, particularly in psychosocial domains. Patients treated with whole-ventricular irradiation had better outcomes. Extensive irradiation field and high irradiation dosage influenced intellectual functions, concept crystallization, executive function, and memory. CONCLUSIONS Tumor location and irradiation field/dosage appear to be the crucial factors related to certain neuropsychological, emotional, and behavioral dysfunctions that in turn alter the quality of life in children with icGCTs who survive after treatment.

Neurocognitive Functioning in Schizophrenia and Bipolar Disorder: Clarifying Concepts of Diagnostic Dichotomy vs. Continuum. Front Psychiatry 2013; 4:162. [PMID: 24367337 PMCID: PMC3852029 DOI: 10.3389/fpsyt.2013.00162] [Citation(s) in RCA: 28] [Impact Index Per Article: 2.5] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 08/01/2013] [Accepted: 11/21/2013] [Indexed: 11/13/2022] Open
Abstract
The Kraepelinian dichotomy posits that patients with schizophrenia (SCZ) and bipolar disorder (BD) present as two separate psychotic entities such that they differ in terms of clinical severity including neurocognitive functioning. Our study aimed to specifically compare and contrast the level of neurocognitive functioning between SCZ and BD patients and identify predictors of their poor neurocognitive functioning. We hypothesized that patients with SCZ had a similar level of neurocognitive impairment compared with BD. About 49 healthy controls (HC), 72 SCZ, and 42 BD patients who were matched for age, gender, and premorbid IQ were administered the Brief Assessment of Cognition battery (BAC). Severity of psychopathology and socio-occupational functioning were assessed for both patients groups. Both BD and SCZ groups demonstrated similar patterns of neurocognitive deficits across several domains (verbal memory, working memory, semantic fluency, processing speed) compared with HC subjects. However, no significant difference was found in neurocognitive functioning between BD and SCZ patients, suggesting that both patient groups suffer the same degree of neurocognitive impairment. Patients with lower level of psychosocial functioning [F (1,112) = 2.661, p = 0.009] and older age [F (1,112) = -2.625, p = 0.010], not diagnosis or doses of psychotropic medications, predicted poorer overall neurocognitive functioning as measured by the lower BAC composite score. Our findings of comparable neurocognitive impairments between SCZ and BD affirm our hypothesis and support less the Kraepelinian concept of dichotomy but more of a continuum of psychotic spectrum conditions. This should urge clinicians to investigate further the underlying neural basis of these neurocognitive deficits, and be attentive to the associated socio-demographic and clinical profile in order to recognize and optimize early the management of the widespread neurocognitive deficits in patients with SCZ and BD.

Abstract
OBJECTIVE Hypothyroidism is a metabolic condition that can lead to cognitive and behavioral deficits in children and adolescents. However, there is less evidence about subclinical hypothyroidism (SH) as a risk factor for neuropsychological disorders in childhood. The aim of this study was to evaluate cognitive functions like active/passive attention, maintaining attention, and response inhibition in pediatric patients with SH. METHODS Seventeen patients (between 7-17 years old) with SH were tested with the Stroop test, Verbal Fluency test and the sub-tests of the Wechsler intelligence scale for children-Revised (WISC-R). SH diagnosis was based on the mild increase of serum thyrotropin (TSH) level together with a normal serum free thyroxine level and an exaggerated TSH response to thyrotropin-releasing hormone. RESULTS Out of seventeen cases, 10 (59%) were girls and 7 (41%) were boys. Six cases were obese and 5 were overweight. The children in the SH group, as compared to the control group, obtained significantly lower scores on both the Digit Span subtest of the WISC-R and the Stroop subtests, which are sensitive to attention. No significant differences were found between the SH group and the healthy controls in verbal fluency and encoding tests. CONCLUSION In this study, pediatric patients with SH showed poor performance in tests measuring attention. Therefore, we want to stress the importance of close collaboration between pediatric endocrinology and child and adolescent psychiatry departments.
