The aim of this study was to evaluate the Childhood Autism Rating Scale (CARS), Autism Treatment Evaluation Checklist (ATEC), and Children’s Global Assessment Scale (CGAS) after anodal transcranial direct current stimulation (tDCS) in individuals with autism. Twenty patients with autism received 5 consecutive days of both sham and active tDCS stimulation (1 mA) in a randomized double-blind crossover trial over the left dorsolateral prefrontal cortex (F3) for 20 minutes in different orders. Measures of CARS, ATEC, and CGAS were administered before treatment and at 7 days posttreatment. The result showed statistical decrease in CARS score (P<0.001). ATEC total was decreased from 67.25 to 58 (P<0.001). CGAS was increased at 7 days posttreatment (P=0.042). Our study suggests that anodal tDCS over the F3 may be a useful clinical tool in autism.

Background: Transcranial direct current stimulation (tDCS) applied to the left dorsolateral prefrontal cortex (dlPFC) might be a promising treatment strategy for depression. As disturbances in psychomotor activity are one of the key features of unipolar depression are, we aimed to evaluate the behavioral effects of ten tDCS sessions over a 5-day period on psychomotor retardation in depressed patients. Methods: Twenty-three treatment-resistant depressed patients received either active or sham anodal tDCS to the left dorsolateral prefrontal cortex (2 mA, 10 sessions over 1 week). Psychomotor functioning was registered by means of observer ratings (Salpêtrière Retardation Rating Scale—SRRS) and objective measures (kinematical analysis of movements, automatic imitation). Results: tDCS sessions resulted in improvements on SRRS scores, although active tDCS was not significantly superior to sham tDCS on the kinematical parameters. Furthermore, no general additional antidepressant effect of tDCS was observed. The relatively small sample size and the short periods of observation should be considered when interpreting these results. Conclusion: tDCS did not induce a clinically relevant effect on psychomotor function in active and sham stimulation groups.

Abstract Objective The aim of this trial was to investigate the effects of five consecutive sessions of anodal transcranial direct current stimulation (tDCS) over the motor cortex (M1) on pain, mood, and physical performance in patients with primary dysmenorrhea (PDM). Design This is a double-blind randomized controlled trial. Subjects Twenty-two participants with PDM according to the No. 345-PDM Consensus Guideline were included. Methods Eleven active treatment and 11 sham stimulation patients received five applications over a one-week period. The primary outcome measures were pain evaluated by numeric rating scale (NRS) and McGill Questionnaire score. Secondary outcomes measures were responses to the Positive and Negative Affect Schedule (PANAS), Hamilton Anxiety Scale (HAM-A), grip strength, and six-minute walk test (6MWT). Baseline data were performed during the first menstrual cycle, and during the second menstrual cycle, participants were conducted to tDCS treatment, and postintervention data were collected. Results The intervention provided significant improvements on NRS in active tDCS, shown as an interaction between group intervention vs pre/postintervention vs days of menstrual cycle (Wald x2 = 10.54, P = 0.005), main effect of days of menstrual cycle (Wald x2 = 25.42, P &lt; 0.001), and pre/postintervention (Wald x2 = 6.97, P = 0.008). McGill showed an interaction effect between pre/postintervention and group of stimulation (Wald x2 = 18.45, P = 0.001), with a large reduction in active tDCS (P &lt; 0.001, d = 0.75). Psychological and functional outcomes did not differ between groups or pre/postintervention. Conclusions tDCS could provide pain relief in subjects with PDM. These results provide some preliminary evidence for the potential role of tDCS as a contributor to the management of symptoms of PDM.

Follow Up Study

ObjectivesTranscranial direct current stimulation (tDCS) is a non-invasive neurostimulation technique that has received increasing interest in the area of mood disorders over the last several years. While acute, double-blind, sham-controlled studies have already reported positive findings in terms of efficacy and safety for tDCS, follow-up data are lacking. This need prompted the present follow-up study, which assesses post-acute effects of tDCS (no maintenance stimulation was performed), in the mid-term, in a sample of major depressives.MethodsAfter completing an acute, open trial of tDCS, 23 outpatients with either major depressive disorder or bipolar disorder entered a naturalistic follow-up (T1) with clinical evaluations at one week (T2), 1 month (T3), and 3 months (T4). A quantitative analysis of Hamilton Depression Rating Scale (HAM-D), Montgomery–Asberg Depression Rating Scale (MADRS), and Young Mania Rating Scale (YMRS) total scores, through repeated measures analysis of variance (ANOVA) (T1–T4) and paired t-test for comparing specific time points (T1–T2, T2–T3, and T3–T4), was performed. In addition, a qualitative analysis on the basis of treatment response and remission (HAM-D) was performed.ResultsEven though a progressive reduction of follow-up completers was observed from T2 to T4 (95.6% at T2, 65.2% at T3, and 47.8% at T4), the antidepressant effects of acute tDCS persisted over 3 months in almost half of the sample. Of note, no post-acute side effects emerged during the follow-up observation. The most frequent causes of drop-out from this study included major modifications in therapeutic regimen (30%) and poor adherence to follow-up visits (17%).ConclusionsIn this mid-term, open, follow-up study, tDCS showed mixed results. Further controlled studies are urgently needed to assess its effects beyond the acute phase.

AbstractBackground:Transcranial direct current stimulation (tDCS) is a non-invasive, neuromodulatory technique with an emerging role for treating major depression.Objective:To investigate the interactions between tDCS and drug therapy in unipolar and bipolar depressed patients who were refractory for at least one pharmacological treatment.Methods:This was a naturalistic study using data from 54 female and 28 male patients (mean age of 54 years) that consecutively visited our psychiatric unit. They received active tDCS (five consecutive days, 2 mA, anodal stimulation over the left and cathodal over the right dorsolateral prefrontal cortex, twice a day, 20 minutes). The outcome variable (mood) was evaluated using the Beck Depression Inventory (BDI) and the Hamilton Depression Rating Scale (HDRS). Predictor variables were age, gender, disorder and pharmacological treatment (seven dummy variables). We performed univariate and multivariate analyses as to identify predictors associated to the outcome.Results:After 5 days of treatment, BDI and HDRS scores decreased significantly (29% ± 36%, 18% ± 9%, respectively, P < 0.01 for both). Benzodiazepine use was independently associated with a worse outcome in both univariate (β = 4.92, P < 0.01) and multivariate (β = 5.8, P < 0.01) analyses; whereas use of dual-reuptake inhibitors positively changed tDCS effects in the multivariate model (β = –4.7, P = 0.02). A similar trend was observed for tricyclics (β = –4, P = 0.06) but not for antipsychotics, non-benzodiazepine anticonvulsants and other drugs.Conclusion:tDCS over the DLPFC acutely improved depressive symptoms. Besides the inherent limitations of our naturalistic design, our results suggest that tDCS effects might vary according to prior pharmacological treatment, notably benzodiazepines and some antidepressant classes. This issue should be further explored in controlled studies.
