Abstract
Background: Electroconvulsive therapy (ECT) is one of the most effective treatments for severe refractory mental diseases. Widespread cognitive complications have affected the acceptance of this treatment. Despite current evidence of short-term cognitive impairment, long-term cognition consequences are less determined. Objectives: This study aimed to evaluate the clinical approach of psychiatrists, psychiatry residents, and nurses in psychiatric hospitals to the necessity, method, and frequency of cognitive assessment in candidate patients for ECT. Methods: In this descriptive study, 89 professional members of Roozbeh and Razi hospitals, Tehran, Iran, including nurses, residents, and faculty members of psychiatry, were selected using the purposive sampling method. The research questionnaires were sent, and 58 fulfilled questionnaires were sent back. The data were analyzed using central indicators and statistical dispersion. The designed questionnaire included the items related to the specialists’ views on the necessity of post-ECT cognitive evaluations, best batteries, frequency of performing the tests, and other related domains. Results: After close follow-up, 58 out of 89 participants completed the questionnaires, including 17 psychiatrists (29.3%), 20 nurses (34.5%), and 21 psychiatry residents (36.2%). The results were analyzed and interpreted in detail. The average work experience of respondents in the psychiatry field was 6.89 years (range: 1 - 25 years). Additionally, 97% of the specialists did not have any project in the ECT field and cognitive disorders. More than 80% of the participants believed that cognition evaluation is necessary for ECT-candidate patients; however, only 15% of the specialists referred patients for the assessment. Moreover, 43% of the experts recommended the Wechsler Memory Scale-Revised; nevertheless, nearly 26% of the experts recommended the Delis-Kaplan Executive Function System for the cognitive assessment of these patients. The Rey Auditory Verbal Learning Test was recommended by 20% of the experts. Nearly two-thirds of the respondents believed that a proper assessment should be carried out in about 30 minutes. More than 60% of the experts believed that patients should be evaluated before receiving the first session of ECT, and nearly one-third of the experts recommended only a post-ECT evaluation. More than half of the experts believed that ECT should be discontinued in case of severe cognitive impairment after ECT. Alternatively, less than 30% of the experts believed that it is necessary to make changes in the treatment dose and the interval between sessions. Furthermore, 80% of the experts recommended cognitive rehabilitation for patients with significant cognitive impairment after ECT; nonetheless, less than 20% of the experts recommended treatment with a cholinesterase inhibitor. Conclusions: A large percentage of patients do not undergo a comprehensive cognitive assessment after ECT, which is an important challenge in the estimation of post-ECT cognitive decline. There is a need to design inexpensive and sensitive tests for cognitive assessment. The test could measure different cognitive domains and be acceptable in terms of time. Due to the limited number of specialists working in this field, the frequency of assessment and treatment methods after the identification of cognitive disorders are heterogeneous. Therefore, it is required to design a native and practical guideline. These results could help the researchers design future studies to determine the best method of cognitive evaluation after ECT, appropriate batteries, recommended intervals, and treatment decisions after cognitive decline detection.

The utility of the brief ECT cognitive screen (BECS) for early prediction of cognitive adverse effects from ECT: A CARE network study. J Psychiatr Res 2021; 145:250-255.

Abstract
Although highly effective, electroconvulsive therapy (ECT) often produces cognitive side effects which can be a barrier for patients. Monitoring cognitive side effects during the acute course is therefore recommended to identify patients at increased risk for adverse outcomes. The Brief ECT Cognitive Screen (BECS) is a brief instrument designed to measure emerging cognitive side effects from ECT. The aim of this study was to examine the clinical utility of the BECS for predicting adverse cognitive outcomes in real world clinic settings. The study included data collated from four participating sites in the Clinical Alliance for ECT and Related treatments (CARE) network. The BECS was administered at pre ECT and post 3 or 4 ECT. The primary outcome was a ≥4 point decrease on the Montreal Cognitive Assessment (MoCA) from pretreatment to post ECT. Logistic multiple regression analyses examined the BECS and other relevant clinical and demographic and treatment factors as predictors. The final analysis included 623 patients with diverse indications for ECT including 53.6% with major depression and 33.7% with schizophrenia or schizoaffective disorder. A higher total score on the BECS significantly predicted decline in Total Scores on the MoCA [B = 0.25 (0.08), p = 0.003], though not decline in MoCA Delayed Recall scores (p > 0.1). Other significant predictors included higher pretreatment MoCA Total Scores and female gender for verbal anterograde memory decline. This study confirmed that the BECS has clinical utility for identifying patients with both reduced and increased risk for adverse cognitive outcomes from ECT.

Abstract
BACKGROUND The electrode placement and pulse width for electroconvulsive therapy (ECT) are important treatment parameters associated with ECT related retrograde memory side-effects. Modification of these parameters with right unilateral (RUL) ECT may have utility for further reducing these side-effects. OBJECTIVE This study explored use of the frontoparietal (FP) placement for reducing retrograde memory side effects with ECT. We hypothesised that superior retrograde memory outcomes would occur with FP compared to temporoparietal (TP) placement and with ultrabrief (UB: 0.3 ms) compared to brief pulse (BP: 1.0 ms) width ECT. METHODS In this randomised cross-over, double-blinded study, participants received a single treatment of BP TP, BP FP, UB TP and UB FP ECT. Neuropsychological testing was conducted prior to and immediately following each treatment. Computational modelling was conducted to explore associations between E-fields in regions-of-interest associated with memory. RESULTS Nine participants completed the study. The FP placement was not superior to TP for retrograde memory outcomes. For both electrode placements UB pulse width was associated with significantly better visual retrograde memory compared to BP (p < .05). With TP ECT, higher E-fields in regions-of-interest were significantly associated with greater visual retrograde memory side-effects (hippocampi: r = -0.77, p = .04; inferior frontal gyri: r = -0.92, p < .01; middle frontal gyri: r = -0.84, p = .02). CONCLUSIONS Modification of pulse-width had greater effects than electrode placement for reducing retrograde memory side-effects with RUL ECT. Preliminary findings suggested that higher E-fields may be associated with greater cognitive side-effects with ECT.

Abstract
OBJECTIVES To review brief cognitive screening instruments for routine clinical monitoring in electroconvulsive therapy. METHODS Brief cognitive screening instruments specifically developed for electroconvulsive therapy and commonly used brief generalised cognitive screening instruments were reviewed with relative advantages and disadvantages highlighted. RESULTS Several brief cognitive screening tests designed for use in electroconvulsive therapy have been found sensitive for monitoring electroconvulsive therapy-related cognitive side effects. The choice of a brief generalised cognitive screening instrument for use in an electroconvulsive therapy clinical context comes with several pertinent considerations. CONCLUSION Electroconvulsive therapy is a highly effective treatment for pharmacoresistant and severe neuropsychiatric illness although cognitive side effects can be a barrier for treatment. Routine monitoring using brief cognitive screening instruments has advantages in busy clinical settings and can assist with optimising patient outcomes. More detailed neuropsychological assessment is recommended if the results from brief cognitive screening raise concerns.
