Comparing neurocognitive impairment in schizophrenia and bipolar I disorder using the Screen for Cognitive Impairment in Psychiatry Scale
2014
AbstractThe purpose of this study was to compare the psychometric properties of the Screen for Cognitive Impairment in Psychiatry (SCIP) when applied to patients diagnosed with schizophrenia (n=126) or bipolar I disorder (n=76), and also to compare the cognitive impairment in both samples of patients and a control group (n=83) using the SCIP and a complete neuropsychological battery. The SCIP is a scale intended to quickly and easily assess cognitive impairment in patients with severe psychiatric disorders. The results showed firstly that, in terms of internal consistency, temporal stability, dimensional structure, and criterion-referenced validity, the SCIP provides reliable and valid scor…
Neurocognitive impairment and psychosocial functioning in bipolar II disorder
2011
Sole B, Bonnin CM, Torrent C, Balanza-Martinez V, Tabares-Seisdedos R, Popovic D, Martinez-Aran A, Vieta E. Neurocognitive impairment and psychosocial functioning in bipolar II disorder. Objective: There is a growing body of evidence on neurocognitive impairment in euthymic bipolar patients, but this issue has been studied mostly in bipolar I disorder, data on bipolar II (BD-II) are scant and discrepant. The two aims of this study were to ascertain whether strictly defined euthymic BD-II patients would present neurocognitive disturbances and to evaluate their impact on functional outcome. Method: Forty-three BD-II patients and 42 demographically and educationally matched healthy subjects …
Neurocognition in bipolar disorders—A closer look at comorbidities and medications
2010
The last decade has witnessed a growing interest in the neuropsychological study of bipolar disorder (BD). This chronic mood disorder is associated with persistent neurocognitive impairments even during periods of euthymia, particularly in the broad domains of attention, verbal memory and executive functions. More interestingly, cognitive dysfunction seems to predict a poorer functional outcome among BD patients and thus represents an important target for future therapies. The aetiology of cognitive dysfunction is probably multifactorial, including gene-environment interactions with potentially confounding variables as well. Drug-induced cognitive adverse effects represent an important and …
The Neurophysiological Responses of Concussive Impacts: A Systematic Review and Meta-Analysis of Transcranial Magnetic Stimulation Studies
2020
Aim: This systematic review and meta-analysis investigated neurophysiological responses using transcranial magnetic stimulation (TMS) following a concussion or sub-concussion. Methods: A systematic searching of relevant databases for peer-reviewed literature quantifying motor evoked potentials from TMS between 1999 and 2019 was performed. A meta-analysis quantified pooled data for measures including motor threshold, motor latency, and motor evoked potential amplitude and for inhibitory measures such as cortical silent period duration, short-interval intracortical inhibition (SICI), and long-interval intracortical inhibition (LICI) ratios. Results: Fifteen articles met the inclusion criteria…
Frontal Electroencephalogram Alpha Asymmetry during Mental Stress Related to Workplace Noise
2021
This study aims to investigate the effects of workplace noise on neural activity and alpha asymmetries of the prefrontal cortex (PFC) during mental stress conditions. Workplace noise exposure is a pervasive environmental pollutant and is negatively linked to cognitive effects and selective attention. Generally, the stress theory is assumed to underlie the impact of noise on health. Evidence for the impacts of workplace noise on mental stress is lacking. Fifteen healthy volunteer subjects performed the Montreal imaging stress task in quiet and noisy workplaces while their brain activity was recorded using electroencephalography. The salivary alpha-amylase (sAA) was measured before and immedi…

Abstract Background Neurofeedback (NF) in children with ADHD has been investigated in a series of studies over the last years. Previous studies did not unanimously support NF as a treatment in ADHD. Most studies did not control for unspecific treatment effects and did not demonstrate that self-regulation took place. The present study examined the efficacy of NF in comparison to electromyographic feedback (EMG) to control for unspecific effects of the treatment, and assessed self-regulation of slow cortical potentials (SCP). Methods A total of 150 children aged 7 - 9 years diagnosed with ADHD (82% male; 43% medicated) were randomized to 25 sessions of feedback of slow cortical potentials (NF…
EEG Microstates Analysis in Young Adults With Autism Spectrum Disorder During Resting-State
2019
Electroencephalography (EEG) is a useful tool to inspect the brain activity in resting state and allows to characterize spontaneous brain activity that is not detected when a subject is cognitively engaged. Moreover, taking advantage of the high time resolution in EEG, it is possible to perform fast topographical reference-free analysis, since different scalp potential fields correspond to changes in the underlying sources within the brain. In this study, the spontaneous EEG resting state (eyes closed) was compared between 10 young adults ages 18-30 years with autism spectrum disorder (ASD) and 13 neurotypical controls. A microstate analysis was applied, focusing on four temporal parameters…
2019
Current research demonstrates beneficial effects of physical activity on brain functions and cognitive performance. To date, less is known on the effects of gross motor movements that do not fall into the category of sports-related aerobic or anaerobic exercise. In previous studies, we found beneficial effects of dynamic working environments, i.e., environments that encourage movements during cognitive task performance, on cognitive performance and corresponding brain activity. Aim of the present study was to examine the effects of working in a dynamic and a static office environment on attentional and vigilance performance, and on the corresponding electroencephalographic (EEG) brain oscil…
J14 Mediterranean Diet And Nutritional Composition Of Patients With Huntington's Disease. Spanish Multicenter Study Of The European Group For Hunting…
2014
Background The impact of a diet is well known in human health. Intake of food groups (fruits and ‘uts, vegetables, legumes, olive oil, whole grains, fish and wine) in the traditional Mediterranean Diet (MeDi) and high MeDi adherence have been associated with lower incidence of chronic diseases and slower cognitive decline, but the relationship between MeDi adherence and nutritional composition has not been reported. Objectives To describe MeDi and nutritional composition in patients with HD. Methods Spanish multicenter, cross-sectional study (EHDN). To assess MeDi we used a 3-days dietary record. Food groups, macro and micronutrients and energy intake information were obtained using the sof…
Utilization of professional psychological care in a large German sample of cancer patients
2016
Objective Although one-third of cancer patients are perceived to have a need for psychological support based on the percentage of mental disorders, little is known about the actual utilization of psychological care in cancer. We aimed to assess cancer patients' reported use of psychological care and its correlates in a large, representative sample. Methods In a multicenter, cross-sectional study in Germany, 4020 cancer patients (mean age 58 years, 51% women) were evaluated. We obtained self-reports of use of psychotherapy and psychological counseling. We measured distress with the Distress Thermometer, symptoms of depression with the Patient Health Questionnaire, anxiety with the Generalize…
