    The acute impact of the early stages of COVID-19 pandemic in people with pre-existing psychiatric disorders: A systematic review
    2022-04-23 - Carvalho, Sandra; Coelho, Catarina G.; Kluwe-Schiavon, Bruno; Magalhães, Juliana; Leite, Jorge; Leite, Jorge
    People with pre-pandemic health conditions are more vulnerable and more likely to suffer greater psychosocial impact due to the current COVID-19 pandemic and the lockdown measures. Thus, the objective of this work was to systematically review the impact of the early stages COVID-19 pandemic on people with pre-existing psychiatric disorders. The search was performed between 23 January and 2 September 2021 in PubMed, PsycINFO, and EMBASE. A total of 4167 published results were identified; however, only 49 were included in this review. Results show that there was considerable heterogeneity among studies, which resulted in a low consensus. However, it seems that the impact of the first stage of the COVID-19 pandemic on psychiatric disorders was two-fold: (1) an overall effect, in which people suffering from psychiatric disorders in general experienced more psychological distress and anxiety when compared to people who had no psychiatric diagnosis, and (2) a condition-specific effect, namely in people suffering from eating disorders and obsessive compulsive disorders. Moreover, the current work highlights that there were also some external factors that were related to worsening symptoms. For instance, unemployment or experiencing work and financial difficulties can be a trigger for greater distress during the pandemic for people with mood disorders, and being alone and in social isolation during the COVID-19 pandemic may actually increase substance use and relapse rates. Further studies are needed to prospectively investigate the long-term effects of the current COVID-19 pandemic on people with (pre)-existing psychiatric conditions and on the onset or deterioration of psychiatric-related symptoms in a larger number of participants, as well as exploring the long-term effects of the current pandemic on mental health.

    2022-09-05 - Brunoni, André R; Ekhtiari, Hamed; Antal, Andrea; Auvichayapat, Paradee; Baeken, Chris; Benseñor, Isabela M; Bikson, Marom; Boggio, Paulo; Borroni, Barbara; Brighina, Filippo; Brunelin, Erome; Carvalho, Sandra; Caumo, Wolnei; Ciechanski, Patrick; Charvet, Leigh; Clark, Vincent P; Kadosh, Roi Cohen; Cotelli, Maria; Datta, Abhishek; Deng, Zhi-De; Raedt, Rudi De; Ridder, Dirk De; Fitzgerald, Paul B; Floel, Agnes; Frohlich, Flavio; George, Mark S; Ghobadi-Azbari, Peyman; Goerigk, Stephan; Hamilton, Roy H; Jaberzadeh, Shapour J; Hoy, Kate; Kidgell, Dawson J; Zonoozi, Arash Khojasteh; Kirton, Adam; Laureys, Steven; Lavidor, Michal; Lee, Kiwon; Leite, Jorge; Lisanby, Sarah H; Loo, Colleen; Martin, Donel M; Miniussi, Carlo; Mondino, Marine; Monte-Silva, Katia; Morales-Quezada, Leon; Nitsche, Michael A; Okano, Alexandre H; Oliveira, Claudia S; Onarheim, Balder; Pacheco-Barrios, Kevin; Padberg, Frank; Nakamura-Palacios, Ester M; Palm, Ulrich; Paulus, Walter; Plewnia, Christian; Priori, Alberto; Rajji, Tarek K; Razza, Lais B; Rehn, Erik M; Ruffini, Giuliov; Schellhorn, Klaus; Zare-Bidoky, Mehran; Simis, Marcel; Skorupinski, Pawel; Suen, Paulo; Thibaut, Aurore; Valiengo, Leandro C L; Vanderhasselt, Marie-Anne; Vanneste, Sven; Venkatasubramanian, Ganesan; Violante, Ines R; Wexler, Anna; Woods, Adam J; Fregni, Felipe; Leite, Jorge
    Objective: Although relatively costly and non-scalable, non-invasive neuromodulation interventions are treatment alternatives for neuropsychiatric disorders. The recent developments of highly-deployable transcranial electric stimulation (tES) systems, combined with mobile-Health technologies, could be incorporated in digital trials to overcome methodological barriers and increase equity of access. The study aims are to discuss the implementation of tES digital trials by performing a systematic scoping review and strategic process mapping, evaluate methodological aspects of tES digital trial designs, and provide Delphi-based recommendations for implementing digital trials using tES. Methods: We convened 61 highly-productive specialists and contacted 8 tES companies to assess 71 issues related to tES digitalization readiness, and processes, barriers, advantages, and opportunities for implementing tES digital trials. Delphi-based recommendations (>60% agreement) were provided. Results: The main strengths/opportunities of tES were: (i) non-pharmacological nature (92% of agreement), safety of these techniques (80%), affordability (88%), and potential scalability (78%). As for weaknesses/ threats, we listed insufficient supervision (76%) and unclear regulatory status (69%). Many issues related to methodological biases did not reach consensus. Device appraisal showed moderate digitalization readiness, with high safety and potential for trial implementation, but low connectivity. Conclusions: Panelists recognized the potential of tES for scalability, generalizability, and leverage of digital trials processes; with no consensus about aspects regarding methodological biases. Significance: We further propose and discuss a conceptual framework for exploiting shared aspects between mobile-Health tES technologies with digital trials methodology to drive future efforts for digitizing tES trials.

    Functional neuroimaging and behavioral correlates of multisite tDCS as an add-on to language training in a person with post-stroke non-fluent aphasia: A year-long case study
    2024-05-03 - Mendes, Augusto; Lema, Alberto; Soares, José Miguel; Sampaio, Adriana; Carvalho, Sandra; Leite, Jorge
    Mary, who experienced non-fluent aphasia as a result of an ischemic stroke, received 10 years of personalized language training (LT), resulting in transient enhancements in speech and comprehension. To enhance these effects, multisite transcranial Direct Current Stimulation (tDCS) was added to her LT regimen for 15 sessions. Assessment using the Reliable Change Index showed that this combination improved her left inferior frontal connectivity and speech production for two months and significantly improved comprehension after one month. The results indicate that using multisite transcranial direct current stimulation (tDCS) can improve the effectiveness of language therapy (LT) for individuals with non-fluent aphasia.

    Mind wandering: Tracking perceptual decoupling, mental improvisation, and mental navigation
    2020-10-15 - Gonçalves, Óscar F.; Silva, Mariana Rachel Dias da; Carvalho, Sandra; Coelho, Patrícia; Lema, Alberto; Mendes, Augusto J.; Branco, Diogo; Collus, Jorge; Boggio, Paulo S.; Leite, Jorge; Leite, Jorge
    Background: Mind wandering is a prevalent phenomenon. However, the concept of mind wandering is associated with distinct and often orthogonal concepts, and research- ers are still debating the best strategies to gain access to mind-wandering processes. Nonetheless, there is a progressive acknowledgment that mind wandering is a multi- dimensional and heterogeneous construct. We argue that to fully understand mind wandering, we need to look at dimensions assessing the process (i.e., perceptual decoupling), dynamics (i.e., mental improvisation), and content (i.e., mental naviga- tion). Objective: The objective of this study was to develop a self-report measure of mind wandering—the Mind Wandering Inventory (MWI)—to capture the heterogene- ity of mind wandering in terms of process, dynamic, and content components. Method: Five language versions of the MWI were administered to an international sample of 1,162 individuals. Results: Results showed that the MWI had good levels of internal consistency. In terms of internal structure, we found a first factor to index perceptual decoupling, a second to index mental improvisation, and a third to index mental navigation. Additionally, a study of concurrent validity with Spontaneous and Delib- erate Mind Wandering scales suggested that MWI has significant correlations with previous mind-wandering scales and that factors 1 (perceptual decoupling) and 2 (mental improvisation) seemed to be more closely associated with spontaneous than deliberate mind wandering. Finally, individuals coming from sciences major back- ground reported increased levels of mind wandering when compared with participants from both health, social and human sciences background.

    Modulation of the cognitive event-related potential P3 by transcranial direct current stimulation: Systematic review and meta-analysis
    2022-01 - Mendes, Augusto J.; Pacheco-Barrios, Kevin; Lema, Alberto; Gonçalves, Óscar F.; Fregni, Felipe; Leite, Jorge; Carvalho, Sandra; Leite, Jorge
    Transcranial direct current stimulation (tDCS) has been widely used to modulate cognition and behavior. However, only a few studies have been probing the brain mechanism underlying the effects of tDCS on cognitive processing, especially throughout electrophysiological markers, such as the P3. This meta-analysis assessed the effects of tDCS in P3 amplitude and latency during an oddball, n-back, and Go/No-Go tasks, as well as during emotional processing. A total of 36 studies were identified, but only 23 were included in the quantitative analysis. The results show that the parietal P3 amplitude increased during oddball and n-back tasks, mostly after anodal stimulation over the left dorsolateral prefrontal cortex (p = 0.018, SMD = 0.4) and right inferior frontal gyrus (p < 0.001, SMD = 0.669) respectively. These findings suggest the potential usefulness of the parietal P3 ERP as a marker of tDCS-induced effects during task performance. Nonetheless, this study had a low number of studies and the presence of considerable risk of bias, highlighting issues to be addressed in the future.

    Cognitive effects of transcranial direct current stimulation combined with working memory training in fibromyalgia: A randomized clinical trial
    2018-08-20 - Santos, Vinicius Souza dos Souza dos; Zortea, Maxciel; Alves, Rael Lopes; Naziazeno, Cátia Cilene dos Santos; Saldanha, Júlia Schirmer; Carvalho, Sandra da Conceição Ribeiro; Leite, Jorge; Torres, Iraci Lucena da Silva; Souza, Andressa; Calvetti, Prisla Ücker; Fregni, Felipe; Caumo, Wolnei; Leite, Jorge
    Cognitive dysfunction in fibromyalgia has been reported, especially memory. Anodal transcranial direct current stimulation (tDCS) over the dorsolateral prefrontal cortex (DLPFC) has been effective in enhancing this function. We tested the effects of eight sessions of tDCS and cognitive training on immediate and delayed memory, verbal fluency and working memory and its association with brain-derived neurotrophic factor (BDNF) levels. Forty females with fibromyalgia were randomized to receive eight sessions of active or sham tDCS. Anodal stimulation (2 mA) was applied over the DLPFC and online combined with a working memory training (WMT) for 20 minutes. Pre and post-treatment neurocognitive tests were administered. Data analysis on deltas considering years of education and BDNF as covariates, indicated active-tDCS + WMT significantly increased immediate memory indexed by Rey Auditory Verbal Learning Test score when compared to sham. This effect was dependent on basal BDNF levels. In addition, the model showed active stimulation increased orthographic and semantic verbal fluency scores (Controlled Oral Word Association Test) and short-term memory (Forward Digit Span). The combination of both techniques seemed to produce effects on specific cognitive functions related to short-term and long-term episodic memory and executive functions, which has clinical relevance for top-down treatment approaches in FM.

    Transcranial direct current stimulation as an add-on treatment to cognitive-behavior therapy in first episode drug-naïve major depression patients: The ESAP Study Protocol
    2020-11-03 - Carvalho, Sandra; Gonçalves, Óscar F.; Brunoni, André R.; Fernandes-Gonçalves, Ana; Fregni, Felipe; Leite, Jorge; Leite, Jorge
    Major Depressive Disorder (MDD) affects more than 264 million people worldwide. Current treatments include the use of psychotherapy and/or drugs, however ∼30% of patients either do not respond to these treatments, or do not tolerate the side effects associated to the use of pharmacological interventions. Thus, it is important to study non-pharmacological interventions targeting mechanisms not directly involved with the regulation of neurotransmitters. Several studies demonstrated that transcranial Direct Current Stimulation (tDCS) can be effective for symptoms relief in MDD. However, tDCS seems to have a better effect when used as an add-on treatment to other interventions.

    Maternal mental health in refugees and migrants: a comprehensive systematic review
    2023-08-17 - Almeida, Lígia Moreira; Moutinho, Ana Raquel; Siciliano, Florência; Leite, Jorge; Caldas, José Peixoto; Leite, Jorge
    The first years of motherhood are often difficult for women, requiring large emotional and biophysical adjustments and increased health risks that may combine with social disadvantage and psychosocial conditions towards decreased maternal wellbeing. Those outcomes are usually worse in vulnerable populations, as refugee and migrants. Comprehending mothers’ needs regarding mental health and psychological well-being must be prioritized. A systematic review using MEDLINE, EBSCO, and SCOPUS databases was carried out, searching for population-based studies published between 2012 and 2022 reporting on maternal mental health in displaced populations. A total of 2881 articles were retrieved; 35 publications met the inclusion criteria, being included in the final evaluation. Displaced women tend to be at higher risks of maternal mental distress, due to life stressors, isolation, intrapersonal and background characteristics, mental health stigma, discrimination, and barriers in accessing adequate healthcare. Refugee and asylum-seekers are at the most vulnerable positions. Postpartum depression is the most assessed condition regarding mental health but is manifestly insufficient for public health systems in assuring an adequate state of maternal well-being. Maternal mental healthcare must be patient-centered, more accessible, and available to both native and displaced mothers. PROSPERO Registration Number: CRD42022335343.

    Efficacy and safety of repetitive transcranial magnetic stimulation and transcranial direct current stimulation in memory deficits in patients with Alzheimer's disease: Meta-analysis and systematic review
    2024-03-01 - Mendes, Augusto J.; Leite, Jorge; Fernandes, Sara M.; Rodrigues, Pedro F. S.; Conde, Ana; Rocha, Magda
    Repetitive transcranial magnetic stimulation (rTMS) and transcranial direct current stimulation (tDCS) are two of the most used non-pharmacological interventions for Alzheimer's Disease (AD). However, most of the clinical trials have focused on evaluating the effects on global cognition and not on specific cognitive functions. Therefore, considering that memory loss is one of the hallmark symptoms of AD, we aim to assess the efficacy and safety of tDCS and rTMS in memory deficits. For that, multilevel random effect models were performed considering the standardized mean difference (SMD) between active and sham stimulation. A total of 19 studies with 411 participants demonstrated positive effects in memory after tDCS (SMD=0.20, p = 0.04) and rTMS (SMD=0.44, p = 0.001). Subgroup analysis revealed that tDCS had greater efficacy when administered in temporal regions (SMD=0.32, p = 0.04), whereas rTMS was superior when applied in frontal regions (SMD=0.61, p < 0.001). Therefore, depending on the brain region of stimulation, both interventions produced a positive effect on memory symptoms in AD patients. Finally, the safety of both techniques was observed in the AD population after the reporting of almost no serious events.

    Non-pharmacological treatment-related changes of molecular biomarkers in major depressive disorder: A systematic review and meta-analysisTagedEnd
    2023-01-24 - Irwin, Courtney L.; Coelho, Patrícia S.; Kluwe-Schiavon, Bruno; Silva-Fernandes, Anabela; Gonçalves, Óscar F.; Leite, Jorge; Carvalho, Sandra; Leite, Jorge
    Background: Major depressive disorder (MDD) is a serious mood disorder and leading cause of disability. Despite treatment advances, approximately 30% of individuals with MDD do not achieve adequate clinical response. Better understanding the biological mechanism(s) underlying clinical response to specific psychopharmacological interventions may help fine tune treatments in order to further modulate their underlying mechanisms of action. However, little is known regarding the effect of non-pharmacological treatments (NPTs) on candidate molecular biomarker levels in MDD. This review aims to identify molecular biomarkers that may elucidate NPT response for MDD. Methods: We performed a systematic review and a multilevel linear mixed-effects meta-analyses, and a metaregression. Searches were performed in PubMed, Scopus, and PsycINFO in October 2020 and July 2021. Results: From 1387 retrieved articles, 17 and six studies were included in the systematic review and meta-analyses, respectively. Although there was little consensus associating molecular biomarker levels with symptomology and/or treatment response, brain metabolites accessed via molecular biomarker-focused neuroimaging techniques may provide promising information on whether an individual with MDD would respond positively to NPTs. Furthermore, non-invasive brain stimulation interventions significantly increased the expression of neurotrophic factors (NTFs) compared to sham/placebo, regardless of add-on pharmacological treatment. Conclusions: NTFs are candidate biomarkers to fine-tune NIBS for MDD treatment.
