Psiconeurobiologia dello stress, psiconeuroendocrinologia, psiconeuroimmunologia

La psichiatria è una disciplina che è cresciuta nel corso di un secolo in modo continuo e ricco. La sofferenza mentale è forse cresciuta anche a causa dello stress connaturato a una società più complessa che dà molto, ma che, rispetto al passato, chiede molto di più al singolo. Questo volume presenta una sintesi dei temi principali di una materia molto estesa, un “compendio” appunto, di conoscenze che non dovrebbero mai mancare nella formazione di chi – medico, psicologo, infermiere – si affaccia alle problematiche di salute mentale. Il lettore noterà che il volume non è centrato sulle categorie diagnostiche del DSM-5, ma è ricco di casi clinici esemplificativi e si richiama alla tradizione psicopatologica classica, con particolare attenzione a temi quali il rapporto sanitario-paziente, stress e medicina psicosomatica, epigenetica, “il sentire del clinico”, l’impostazione delle scelte psicofarmacologiche, le diagnosi dimensionali e le psicoterapie farmacosequenziali; una visione decisamente orientata a superare la dicotomia tra psicologico e biologico che attinge alla vasta scelta di terapie e risorse di trattamento, integrandosi con i più recenti sviluppi delle neuroscienze

Problematic Use of the Internet Mediates the Association between Reduced Mentalization and Suicidal Ideation: A Cross-Sectional Study in Young Adults

This article is an open access article distributed under the terms and conditions of the Creative Commons Attribution (CC BY) license (https://creativecommons.org/licenses/by/4.0/).Suicide is a major public health problem, and it is urgent to investigate its underlying clinical and psychological concomitants. It has been suggested that low mentalization skills and problematic use of the internet (PUI) are factors that can play a role in suicidal behaviors. It is possible that poor mentalization skills contribute to leading to forms of PUI, which, in turn, can represent triggers for suicidal ideation (SI). We tested this hypothesis through a quantitative and cross-sectional study on a sample (n = 623) of young adults (age range: 18−34). Self-report measures investigating symptoms related to Social Media Addiction (SMA), Internet Gaming Disorder (IGD), mentalization capacity, and SI were used. A single mediation analysis with two mediators was carried out to evaluate the direct and indirect effects of mentalization on SI through the mediating role of SMA- and IGD-related symptoms, controlling for potential confounding factors (e.g., socio-demographic and addiction-related variables). The four explored variables were significantly associated with each other (all p 0.001) across all subjects; the mediational model showed that the total effect of mentalization on SI was significant (B = −0.821, SE = 0.092 (95% CI: −1.001; −0.641)) and that both SMA- (B = −0.073, SE = 0.034 (95% CI: −0.145; −0.008)) and IGD-related symptoms (B = 0.046, SE = 0.027 (95% CI: −0.107; −0.001)) were significant mediators of such association. Our findings support the possibility that PUI severity plays a relevant role in mediating the association between low mentalization skills and levels of SI.Peer reviewedFinal Published versio

[Contemporary narcissism and paranoid developments] Narcisismo contemporaneo e sviluppi paranoidi

Starting from a psychopathological approach, the current paper sought to describe psychological and relational consequences that in last decades derived from new valorization and productive processes on the basis of substantial socio-cultural transformations. This reasoning arises from the analysis of contemporary society in regard to which the ideology of performance has assumed a prominent role. The society of performance is subservient to the imperatives of profit and valorization which have been internalized by common sense deeply influencing identity related processes. In such a society, specific forms of mental sufferance regarding the experiences of failure, unworthiness and guilt may show up, being related to the potential failure of performances. These transformations show a significant effect on narcissistic dynamics which nowadays seem derived from a more fragile self-ideality. Narcissistic wounds, with their experiences of failure and worthlessness, are not the only psychopathological developments that may occur in this frame. What we sought to describe in the current paper is the possibility of different paranoid experiences arising from intrapsychic tensions in their turn related to the abovementioned socio-cultural transformations. The aim of this contribution was to describe specific transient paranoid developments that never appear structured as true delusions: these psychotic experiences may act as a rebalancing process, somehow compensatory, in regard to such psychological functions that have been stressed by identitary anguish and experiences of failure and worthlessness

Sexual Habits and Sexual Dysfunctions in a Sample of Patients with Psychotic Disorders Compared to a Group of Healthy Adults

Background: There is a growing body of literature on the association between psychosis and sexual dysfunction. However, most studies have focused on sexual dysfunction and have not investigated the sexual lives of patients with psychosis across a broader range. Material and Methods: Consecutive patients with a diagnosis of acute psychosis or schizophrenia were recruited to the study after obtaining informed consent (n = 46). In addition, healthy control subjects were recruited (n = 52). Sociodemographic and clinical data, psychopathology, and sexual functioning were assessed. Independent sample t-test to determine group differences was obtained. Results: In both the male and female groups, there are significant differences between psychotic individuals and healthy controls in several areas of their sexual functioning: the control group seemed to better perceive Couple sexuality, Self-eroticism, and overall appeared to have a higher Quality of sexual life; on the other hand, the group of patients with psychosis displayed higher scores in Sexual dysfunction. Conclusions: A poor sexual quality of life may be found in patients with psychotic disorders. Assessment of sexual function in these patients is necessary to identify and manage issues and provide support and help to patients in this important area of life

Attentional functioning in individuals with 22q11 deletion syndrome. Insight from ERPs

The 22q11 deletion syndrome (22q11DS), or DiGeorge syndrome (DG), is one of the most common genetic deletion syndromes. DG also carries a high risk for psychiatric disorders, with learning disabilities frequently being reported. Impairments in specific cognitive domains, such as executive functioning and attention, have also been described. The aim of this study was to investigate attentional functioning in a group of subjects with DG using ERPs, and in particular the P300 and CNV components. We studied ten patients with DG and ten healthy subjects that performed a P300 Novelty task and a CNV motor task. P3b amplitude was significantly lower in patients than in controls, while P3b latency was comparable in patients and controls. The P3a parameters were similar in both groups. All CNV amplitudes were significantly lower in DG patients than in controls. DG patients displayed slower reaction times in the CNV motor task than healthy subjects. These results point to a cognitive dysfunction related above all to executive attentional processing in DG patients. In particular, a specific difficulty emerged in selective attention and in the ability to orient and to sustain the anticipatory attention required for an executive motor response

Prevalence and incidence of psychotic disorders in 22q11.2 deletion syndrome: a meta-analysis

22q11.2 deletion syndrome (22q.11.2DS) might be one of the strongest genetic risk factors for psychosis, but robust estimates of prevalence and incidence of psychotic disorders in this condition are not available. To address this gap, we performed a multistep systematic PRISMA/MOOSE-compliant literature search of articles reporting prevalence (primary outcome) or incidence (secondary outcome) of psychotic disorders in 22q11.2DS samples (protocol: https://osf.io/w6hpg) using random-effects meta-analysis, subgroup analyses and meta-regressions. The pooled prevalence of psychotic disorders was 11.50% (95%CI:9.40–14.00%), largely schizophrenia (9.70%, 95%CI:6.50–14.20). Prevalence was significantly higher in samples with a mean age over 18 years, with both psychiatric and non-psychiatric comorbidities and recruited from healthcare services (compared to the community). Mean age was also significantly positively associated with prevalence in meta-regressions (p < 0.01). The pooled incidence of psychotic disorders was 10.60% (95%CI:6.60%-16.70%) at a mean follow-up time of 59.27 ± 40.55 months; meta-regressions were not significant. To our knowledge, this is the first comprehensive systematic review and meta-analysis of the prevalence and incidence of psychotic disorders in 22q11.2DS individuals. It demonstrates that around one in ten individuals with 22q11.2DS displays comorbid psychotic disorders, and around one in ten will develop psychosis in the following five years, indicating that preventive approaches should be implemented systematically in 22q11.2DS.</p

Structural Cerebellar Abnormalities and Parkinsonism in Patients with 22q11.2 Deletion Syndrome

Background: The phenotypic expression of 22q11.2 deletion syndrome (22q11.2DS) is variable and may include cognitive, psychiatric, and neurological manifestations, e.g., parkinsonism. We investigated brain structural alterations in patients with 22q11.2DS with and without parkinsonism (Park+ and Park&minus;) in comparison with healthy controls (HCs). Methods: Voxel-based morphometry was performed on 3D T1-weighted MR images to explore gray matter volume (GMV) differences between 29 patients (15 Park+, 14 Park&minus;), selected from a consecutive series of 56 adults diagnosed with 22q11.2DS, and 24 HCs. One-way ANOVA and multiple linear regression analyses were performed to explore group differences in GMV and correlations between clinical scores (MDS-UPDR-III and MoCA scores) and structural alterations. Results: Significant between-group differences in GMV were found in the cerebellum, specifically in bilateral lobes VIII and left Crus II, as well as in the left superior occipital gyrus. Although both Park+ and Park&minus; patients showed GMV decrements in these regions with respect to HCs, GMV loss in the right lobe VIII and left Crus II was greater in Park+ than in Park&minus; patients. GMV loss did not correlate with clinical scores. Conclusions: Patients with 22q11.2DS and parkinsonism manifest specific cerebellar volume alterations, supporting the hypothesis of neurodegenerative processes in specific cerebellar regions as a putative pathophysiological mechanism responsible for parkinsonism in patients with 22q11.2DS

Clozapine-induced gastroesophageal rumination in 22q11.2 Deletion Syndrome. A case report on gastroesophageal side effects management without renouncing clozapine's effectiveness

Despite entailing more severe and uncommon side effects in 22q11.2DS compared to idiopathic schizophrenia, we strongly believe that clozapine should continue to be considered the gold standard for all treatment‐resistant schizophrenia, even in 22qDS

Social cognition and real-life functioning in patient samples with 22q11.2 deletion syndrome with or without psychosis, compared to a large sample of patients with schizophrenia only and healthy controls

Patients with the 22q11.2 deletion syndrome (DS) show an increased risk of developing a psychotic illness lifetime. 22q11.2DS may represent a reliable model for studying the neurobiological underpinnings of schizophrenia. The study of social inference abilities in a genetic condition at high risk for psychosis, like 22q11.2DS, may shed light on the relationships between neurocognitive processes and patients' daily general functioning. The study sample consisted of 1736 participants, divided into four groups: 22q11.2DS patients with diagnosis of psychotic disorder (DEL SCZ, N = 20); 22q11.2DS subjects with no diagnosis of psychosis (DEL, N = 43); patients diagnosed with schizophrenia without 22q11.2DS (SCZ, N = 893); and healthy controls (HC, N = 780). Social cognition was assessed through The Awareness of Social Inference Test (TASIT) and general functioning through the Specific Levels of Functioning (SLoF) scale. We analysed data through regression analysis. The SCZ and DEL groups had similar levels of global functioning; they both had significantly lower SLoF Total scores than HC (p &lt; .001); the DEL SCZ group showed significantly lower scores compared to the other groups (SCZ, p = .004; DEL, p = .003; HC, p &lt; .001). A significant deficit in social cognition was observed in the three clinical groups. In the DEL SCZ and SCZ groups, TASIT scores significantly predicted global functioning (p &lt; .05). Our findings of social cognition deficit in psychosis-prone patients point to the possible future adoption of rehabilitation programmes, like Social Skills Training and Cognitive Remediation, during premorbid stages of psychosis
