    This study examined the reliability, validity and internal structure of the newly developed, interview-based Schedule for the Assessment of Insight in Eating Disorders (SAI-ED) and the relationships of insight with demographic and clinical characteristics in EDs. Ninety-four female patients – 44 with anorexia nervosa (AN) and 50 with bulimia nervosa (BN) – were assessed with SAI-ED. The Brown Assessment of Beliefs Scale was used to evaluate convergent validity of SAI-ED. Hierarchical cluster analysis and multidimensional scaling were used to identify insight components and assess their inter-relationships. The final 8-item SAI-ED demonstrated good psychometric properties. Inter-rater and test-retest reliabilities were high. Three subscales of SAI-ED were identified which measure major insight components: awareness of illness, awareness of symptoms, and treatment engagement. Patients with AN had significant lower score on SAI-ED than patients with BN. Impaired insight was associated with: (a) lower current and lowest lifetime BMI and more severe dietary restrain in AN, (b) illness duration, severity of overall ED symptoms, body-related concerns and obsessionality in BN. Insight is a multidimensional construct in EDs associated with different clinical aspects in AN and BN. The SAI-ED is a valid and reliable tool for the assessment of insight in EDs patients

    Introduction: The objectives of this study were to develop a multidimensional, clinician-rated scale that assess impaired insight into illness in patients with alcohol use disorder (AUD) and to examine its reliability, validity and internal structure. Moreover, we investigated the relationships of overall insight and its dimensions with demographic and clinical characteristics in AUD. Methods: We developed the Schedule for the Assessment of Insight in Alcohol Dependence (SAI-AD), based on scales that has already been used in psychosis and other mental disorders. Sixty-four patients with AUD were assessed with SAI-AD. Hierarchical cluster analysis and multidimensional scaling were used to identify insight components and assess their inter-relationships. Results: The SAI-AD demonstrated good convergent validity (r = −0.73, p < 0.001) and internal consistency (Cronbach's alpha = 0.72). Inter-rater and test-retest reliabilities were high (intra-class correlations 0.90 and 0.88, respectively). Three subscales of SAI-AD were identified which measure major insight components: awareness of illness, recognition of symptoms and need for treatment, and treatment engagement. Higher levels of depression, anxiety and AUD symptom severity were associated with overall insight impairment but not with recognition of symptoms and need for treatment, or with treatment engagement. Illness duration was specifically and positively associated with the treatment engagement component of insight. Conclusions: Insight is a multidimensional construct in AUD and its major components appear to be associated with different clinical aspects of the disorder. The SAI-AD is a valid and reliable tool for the assessment of insight in AUD patients

    Premorbid adjustment (PA) in academic and social domain is a key-predictor of cognitive performance in schizophrenia. Prior studies provided inconsistent findings regarding the differential relationships of PA domains with post-illness cognition. Multivariate associations of academic and social PA in each developmental stage (childhood, early and late adolescence) with post-onset cognitive variables were explored. Furthermore, possible differential relationships of PA domain deterioration courses with post-onset cognitive dysfunction were investigated. Seventy-five schizophrenia patients were evaluated with Premorbid Adjustment Scale (PAS). General cognitive ability, verbal IQ, verbal memory and learning, processing speed, working memory, executive function and premorbid IQ were assessed. Canonical Correlation Analyses revealed that poorer academic PA across childhood and early adolescence was related to worse post-onset verbal IQ, working memory, verbal learning and executive function, while academic PA deterioration between early and late adolescence was associated with poorer verbal learning and executive function and, as further analysis indicated, predicts IQ decline. Academic PA was exclusively associated with post-onset cognitive impairment. New evidence emerged for the specificity of each developmental period in constructing academic PA in its relation to post-illness cognition. Early premorbid academic maladjustment possibly constitutes the onset of a cognitive dysmaturational process which results to post-diagnosis impaired cognition. © 2018 Elsevier B.V

    Adaptive immersive Virtual Environments as a treatment for depersonalization disorder

    No full text
    Depersonalization is a dissociative disorder associated to a profound disruption of self-awareness in the form of emotional numbing and feelings of disembodiment. The salient feature of depersonalization is a breakdown in the familiarity of one&apos;s psychological and somatic self (and surroundings when derealization is also present), in spite of being aware of the unreality of the change. At an early stage of research it was realized that people inclined to dissociation find it harder to tolerate discontinuity in perceptual environments, possibly due to a rigid perceptual attitude. Consequently, perceptual discontinuity experienced during momentary immersion into a VE would be expected to increase symptoms of dissociation among individuals prone to develop them. It has been put forward that a tendency toward immersion or absorption, linking to imaginative processes underlying the dissociative experience, significantly relates to the level of change in virtual reality-induced dissociative symptoms. Consequently, it has been implied that increased tolerability of perceptual discontinuities and a more flexible perceptual attitude in people suffering depersonalization/derealization disorder may be of help. We propose the use of adaptive immersive virtual environments to the treatment of depersonalization. In particular, we propose that implementation of biofeedback electrical stimulation to detect somato-sensory processing bias may contribute to selectively targeting deranged neurocognitive processing components, and as an indirect consequence promote, to some extent, the diagnostic process. Psychophysiological approaches may be of help in the treatment of depersonalization via additional series of afferent inputs - virtual reality (VR) stimuli - to alter the receptive fields of the affected proprioceptive systems and reorganize them. The aim of this paper is to stimulate future research towards the development of potential virtual rehabilitation programs based on biofeedback, electrical stimulation and concurrent measurement of galvanic skin response and EEG targeting selective somatosensory stimulation in patients with depersonalization. Our research hypotheses might constitute a starting point for the development of new treatment tools for depersonalization in particular and depersonalization/derealization disorder in general

    Long-term neuropsychological outcomes following temporal lobe epilepsy surgery: An update of the literature

    No full text
    We present an update of the literature concerning long-term neuropsychological outcomes following surgery for refractory temporal lobe epilepsy (TLE). A thorough search was conducted through the PubMed and Medline electronic databases for studies investigating neu-ropsychological function in adult patients undergoing resective TLE surgery and followed for a mean/median &gt; five years period. Two independent reviewers screened citations for eligibility and assessed relevant studies for the risk of bias. We found eleven studies fulfilling the above requirements. Cognitive function remained stable through long-term follow up despite immedi-ate post-surgery decline; a negative relation between seizure control and memory impairment has emerged and a possible role of more selective surgery procedures is highlighted. © 2021 by the authors.

    Brivaracetam (BRV) is the latest approved antiepileptic drug. The aim of the study was to evaluate the efficacy and tolerability of BRV in everyday clinical practice. In this retrospective, observational, multicenter study, data from epilepsy patients receiving BRV from January 2018 to July 2019 were analyzed. Patients with age ≥16 suffering from any type of epilepsy and having at least one follow up encounter after dose titration were included. 156 consecutive patients were included in the study. The mean age was 40 (16–84 years) and the mean duration of epilepsy was 21 years. Of the 156 patients, 81% were diagnosed with focal-onset seizures, 16% with generalized seizures, while 3% suffered from unclassified seizures. Nine patients received BRV as monother-apy as a switching therapy. At the first follow up visit, seizure cessation was achieved in 56 (36%) patients and the rate of ≥50% responders was 36%. Twenty four patients (15%) remained un-changed; six patients (4%) were recorded with increased seizure frequency, while the remaining 9% had a response of less than 50%. Twenty-six patients (17%) showed clinically significant adverse events, but none were life threatening. Brivaracetam seems to be an effective, easy to use and safe antiepileptic drug in the clinical setting. © 2021 by the authors. Licensee MDPI, Basel, Switzerland

    Factor structure and psychometric properties of the Greek version of Saving Inventory-Revised (SI-R) in a non-clinical sample

    Hoarding disorder is a debilitating condition that results from difficulty or inability to discard possessions and the need to save items and leads to cluttered living space. It impedes normal everyday functioning and causes significant distress and dysfunction. The aim of the current study was to validate the Greek version of the Saving Inventory-Revised (SI-R) in a non-clinical sample of 554 Greek adults. Factor structure and psychometric properties were investigated. Common exploratory (EFA) and confirmatory factor analysis (CFA) were used to explore the factor structure of the data. A three-factor solution was emerged for the Greek SI-R Which appears to cover the clinical dimensions of the phenomenon and consists of clutter, difficulty discarding and acquisition dimensions. This finding is in accordance with the original English version as well as other adaptations of the instrument in other languages. Some items cross loaded but such findings of cross loading items are also reported in related literature. The Greek version of the SI-R exhibits satisfactory internal consistency and good test retest reliability (stability). The current study also aimed to gather evidence towards the convergent and discriminant validity of Greek SI-R. Findings showed no correlation with measurements of different constructs such as anxiety, depression and non-hoarding obsessive compulsive symptoms but also only partial correlation with measurements of relative clinical constructs, such as hoarding items in obsessive compulsive inventories. Current findings suggest that the Greek SI-R can be a useful tool in the detection and evaluation of hoarding symptoms in Greek population

    Familial and socioeconomic contributions to premorbid functioning in psychosis: Impact on age at onset and treatment response

    Background. Premorbid adjustment (PA) abnormalities in psychotic disorders are associated with an earlier age at onset (AAO) and unfavorable clinical outcomes, including treatment resistance. Prior family studies suggest that familial liability, likely reflecting increased genetic risk, and socioeconomic status (SES) contribute to premorbid maladjustment. However, their joint effect possibly indicating gene-environment interaction has not been evaluated. Methods. We examined whether family history of psychosis (FHP) and parental SES may predict PA and AAO in unrelated cases with first-episode psychosis (n = 108) and schizophrenia (n = 104). Premorbid academic and social functioning domains during childhood and early adolescence were retrospectively assessed. Regression analyses were performed to investigate main effects of FHP and parental SES, as well as their interaction. The relationships between PA, AAO, and response to antipsychotic medication were also explored. Results. Positive FHP associated with academic PA difficulties and importantly interacted with parental SES to moderate social PA during childhood (interaction p = 0.024). Positive FHP and parental SES did not predict differences in AAO. Nevertheless, an earlier AAO was observed among cases with worse social PA in childhood (β = -0.20; p = 0.005) and early adolescence (β = -0.19; p = 0.007). Further, confirming evidence emerged for an association between deficient childhood social PA and poor treatment response (p = 0.04). Conclusions. Familial risk for psychosis may interact with parental socioeconomic position influencing social PA in childhood. In addition, this study supports the link between social PA deviations, early psychosis onset, and treatment resistance, which highlights premorbid social functioning as a promising clinical indicator. © The Author(s) 2020.
