Abstract
BACKGROUND Electroconvulsive therapy (ECT) is an established treatment for depression, but more data on effectiveness and safety in clinical practice is needed. The aim of this register-based study was to investigate short-term effectiveness and cognitive safety after ECT, evaluated by clinicians and patients. Secondary, we investigated predictors for remission and cognitive decline. METHODS The study included 392 patients from the Regional Register for Neurostimulation Treatment in Western Norway. Depressive symptoms and cognitive function were assessed with Montgomery-Åsberg Depression Rating Scale and Mini-Mental State Examination (clinician-rated) and Beck Depression Inventory and Everyday Memory Questionnaire (patient-rated). Assessments were done prior to ECT-series and a mean of 1.7 days after (range 6 days before and 12 days after) end of ECT-series. Paired samples t-tests were extended by detailed, clinically relevant subgroups. Predictors were examined using logistic regression. RESULTS Clinician- and patient-rated remission rates were 49.5 and 41.0%, respectively. There was a large reduction in depressive symptoms and a small improvement in cognition after ECT, but we also identified subgroups with non-response of ECT in combination with cognitive decline (4.6% clinician-rated, 15.7% patient-rated). Positive predictors for patient- and clinician-rated remission were increasing age, shorter duration of depressive episode, and psychotic features. Antipsychotic medication at the commencement of treatment and previous ECT-treatment gave higher odds of clinician-rated remission, whereas higher pretreatment subjective depression level was associated with lower odds for patient-rated remission. Clinician-rated cognitive decline was predicted by higher pretreatment MMSE scores, whereas psychotic features, increasing age, and greater pretreatment subjective memory concerns were associated with lower odds for patient-rated cognitive decline. CONCLUSIONS Our study supports ECT as an effective and safe treatment, although subgroups have a less favorable outcome. ECT should be considered at an early stage for older patients suffering from depression with psychotic features. Providing comprehensive and balanced information from clinicians and patients perspectives on effects and side effects, may assist in a joint consent process.

Abstract
OBJECTIVES Electroconvulsive therapy (ECT) is an effective somatic treatment, but it may be limited by cognitive adverse effects. The existing cognitive screening instruments often lack specificity to ECT-associated cognitive deficits. The ElectroConvulsive Therapy Cognitive Assessment was developed and validated in a clinical setting, but the reliability and validity of the Chinese version of ElectroConvulsive Therapy Cognitive Assessment (ECCA-C) have not been studied in a large clinical sample. METHODS The ECCA-C and the Montreal Cognitive Assessment (MoCA) were administered to patients with major depressive disorder (MDD) undergoing ECT at 3 time points: pretreatment (baseline), before the fifth treatment, and 1 week posttreatment. The instruments were also administered to a sample of healthy subjects. RESULTS Sixty-five patients with MDD and 50 age- and sex-matched healthy controls were recruited in this study. Overall, the patient group had statistically significantly lower MoCA and ECCA-C scores than the control group (both P values <0.001). The Cronbach α of the ECCA-C was 0.88 at baseline. Statistically significant decreases over time were observed in ECCA-C: pre-ECT (23.9 ± 4.0) > mid-ECT (21.3 ± 3.4) > post-ECT (18.7 ± 4.8) (all P values <0.001), whereas no statistically significant changes in MoCA scores were found at these 3 time points (F = 1.86, P = 0.165). A cutoff score of 26.5 on the ECCA-C was found to best differentiate between MDD patients and healthy controls. CONCLUSIONS The ECCA-C showed satisfactory psychometric properties and may be a more sensitive instrument than the MoCA to assess cognitive impairment associated with ECT.

Abstract
BACKGROUND Subjective cognitive complaints represent a leading reason for suboptimal prescription of electroconvulsive therapy, the most acutely effective treatment for depression. However, research findings regarding their presentation are conflicting. OBJECTIVE To describe, quantify and explain the variability in subjective cognitive complaints and subjective cognition following electroconvulsive therapy for depression. METHODS We searched systematically PubMed, Embase, PsycARTICLES, CINAHL and relevant reviews for research published from 1 January 1972 to 31 August 2020. We included all independent studies of patients whose subjective cognition was assessed following brief-pulse electroconvulsive therapy for depression. Three meta-analyses were conducted to quantify: (1) the prevalence of patients presenting with cognitive complaints following electroconvulsive therapy; (2) the pre-post electroconvulsive therapy change in subjective cognition and (3) the association between change in depressive symptoms and change in cognitive complaints. Effect sizes were calculated using random-effects models. Eight prespecified demographic and clinical moderators of between-study variability were assessed using sub-group analyses and meta-regressions. RESULTS Data from 72 studies including 5699 participants were meta-analysed. Weighted mean prevalence of patients with cognitive complaints was 48.1% (95% confidence interval = [42.3%, 53.9%]). The type of subjective measure used significantly impacted the pre-post electroconvulsive therapy change in subjective cognition, showing, respectively, large improvement (g = 0.81; 95% confidence interval = [0.59, 1.03]) after electroconvulsive therapy with the Squire Self-Rating Scale of Memory and small worsening (g = -0.48; 95% confidence interval = [-0.70, -0.26]) with 1-item memory scales. The strongest predictors of improved post-electroconvulsive therapy subjective cognition were increased age and larger post-electroconvulsive therapy decrease in depressive symptoms. The weighted mean correlation between pre-post electroconvulsive therapy decrease in depressive symptoms and pre-post electroconvulsive therapy decrease in cognitive complaints was 0.46 (95% confidence interval = [0.39, 0.53]). CONCLUSION Variability in subjective cognition following electroconvulsive therapy is mostly explained by the degree of post-treatment persisting depression and by the subjective assessment used. Scales measuring exclusively subjective worsening present limited clinical utility and instruments allowing the detection of both improvement and worsening in subjective cognition should be preferred.

Abstract
BACKGROUND Despite improvements, studies continue to report unsatisfactory provision of information before, during and after electroconvulsive treatment (ECT). AIMS The study explores participants' experiences with information provision about ECT. METHODS In-depth interviews with 21 participants (21- 65 year-old) were conducted. Thematic analysis resulted in identification of four themes: pre-treatment knowledge, experience of informed consent, the need for information depth and life after ECT. The study includes user involvement. RESULTS Although some participants were satisfied with information provision, the majority experienced an education deficit throughout the treatment period. Their consent was based mostly on oral information, insufficient and unvaried information on official health websites and media. Further, patients reported a lack of follow-up services that can attend to (neuro) psychological concerns. CONCLUSIONS Better access to updated factual and narrative information should support patient education and autonomy. Active use of diary writing, better follow-up and more varied representations of experience with ECT in media and health information sites are necessary to educate, improve consent processes and reduce stigma.

Abstract
OBJECTIVE Electroconvulsive therapy (ECT) is an effective treatment for major depressive disorder; yet, its use is confined to <1% of individuals with this disorder. The authors aimed to examine barriers to ECT from the perspective of the provider. METHODS Qualitative interviews were conducted with U.S.-based ECT providers to identify potential barriers. A quantitative survey was created asking providers to rank-order barriers to starting a new ECT service or expanding existing services. RESULTS Survey responses were received from 192 physicians. Respondents were representative of all ECT providers found in the Medicare Provider Utilization and Payment Database with respect to gender and geographic distribution. Approximately one-third (N=58, 30%) of survey respondents graduated from one of 12 residency programs. Programs with dedicated hospital space were more likely to have larger services than those borrowing surgical recovery space (χ2=25.87, df=1, p<0.001). The most prominent provider-reported barriers to expanding an existing ECT service were lack of physical space, stigma on the part of patients, and transportation difficulties. The most prominent barriers to initiating a new service were lack of well-trained colleagues and ECT practitioners, lack of a champion within the institution, and lack of physical space. Wide geographic variation was found in the availability of ECT, with the highest concentration of ECT providers per 1 million individuals found in New England (6.4), and the lowest found in the West South Central (1.1). CONCLUSIONS Coordinated efforts to overcome identified barriers may allow ECT to be more broadly implemented. Investments in education may increase the number of competent practitioners.

Abstract
Introduction: While short-term cognitive impairment following electroconvulsive therapy (ECT) is well described and acknowledged, the relationship between ECT and persistent memory impairment, particularly of autobiographical memory, has been controversial. Methods: We describe the case of a 70-year-old consultant neurophysiologist, AW, who developed prominent, selective autobiographical memory loss following two courses of ECT for treatment-resistant depression. Results: His performance on standard measures of IQ, semantic and episodic memory, executive function and mood was normal, while he performed significantly below controls on measures of episodic autobiographical memory. Conclusions: Explanations in terms of mood-related memory loss and somatoform disorder appear unlikely. We relate AW's autobiographical memory impairment, following his ECT, to reports of similar autobiographical memory impairment occurring in the context of epilepsy, and emphasise the importance of using sensitive approaches to AbM assessment.

Abstract
Electroconvulsive therapy (ECT) is an effective modality of treatment for a variety of psychiatric disorders. However, it has always been accused of being a coercive, unethical, and dangerous modality of treatment. The dangerousness of ECT has been mainly attributed to its claimed ability to cause brain damage. This narrative review aims to provide an update of the evidence with regard to whether the practice of ECT is associated with damage to the brain. An accepted definition of brain damage remains elusive. There are also ethical and technical problems in designing studies that look at this question specifically. Thus, even though there are newer technological tools and innovations, any review attempting to answer this question would have to take recourse to indirect methods. These include structural, functional, and metabolic neuroimaging; body fluid biochemical marker studies; and follow-up studies of cognitive impairment and incidence of dementia in people who have received ECT among others. The review of literature and present evidence suggests that ECT has a demonstrable impact on the structure and function of the brain. However, there is a lack of evidence at present to suggest that ECT causes brain damage.

Abstract
BACKGROUND Electroconvulsive therapy (ECT) is a well-established treatment for severe depression but may result in adverse cognitive effects. Available cognitive screening instruments are nonspecific to the cognitive deficits associated with ECT. An ECT-cognitive assessment tool which can be easily administered was developed and validated in a clinical setting. METHODS One hundred and thirty-six participants were enrolled. The ElectroConvulsive therapy Cognitive Assessment (ECCA) and the Montreal Cognitive Assessment (MoCA) were administered prospectively to 55 participants with major depressive disorder (MDD) undergoing ECT at three time points: pre-treatment, before the sixth treatment and one-week post-treatment. The psychometric properties of the total and domain scores were evaluated at all three time points. Forty demographically comparable participants with MDD who did not receive ECT, and 41 healthy, age-matched controls were evaluated at a single time point. RESULTS ECCA and MoCA scores were not statistically different at baseline. Prior to the sixth and final ECT session, total ECCA scores were significantly lower than the MoCA total scores. The ECCA domains of subjective memory, informant-assessed memory, attention, autobiographical memory and delayed verbal recall were significantly lower post-ECT compared to pre-ECT. LIMITATIONS The ECCA was compared only to the MoCA rather than to a more comprehensive neuropsychological testing. This limitation reflected the real-life clinical burden of performing full neuropsychological testing at three time points during the treatment course. CONCLUSIONS The ECCA is a brief, reliable, bedside cognitive screening assessment tool that may be useful to monitor cognitive function in patients treated with ECT. The test can be downloaded from fuquacenter.org/ecca.

Abstract
BACKGROUND Electroconvulsive therapy (ECT) is a controversial treatment. Research has predominantly focused on clinician assessment of short-term efficacy and, occasionally, on participant experiences of the treatment itself. While service user accounts of the long-term impacts of ECT are reported, they are dispersed throughout the literature and typically tangential to studie's main foci. AIM The aim of this study was to synthesise service-user accounts, within peer-reviewed literature, of long-term impacts of ECT in their daily lives. METHODS A qualitative meta-synthesis was conducted. A systematic literature search identified qualitative articles meeting the inclusion criteria. Results sections of eligible papers were analysed thematically. RESULTS From 16 eligible papers, the review identified 11 long-term impacts, four social influences and five strategies that people employed to navigate these long-term impacts. CONCLUSION Limited research has examined long-term experiences of ECT from service-user perspectives. These lived experience perspectives are required to facilitate peer-to-peer learning and assist future service delivery to align with needs of people living with long-term ECT impacts.

Abstract
BACKGROUND Electroconvulsive therapy (ECT) is an effective treatment for depression, but there is risk of cognitive adverse events. This risk has been partially attributed to electrical charge, thus the optimal electrical stimulus dose is still under discussion. The aim of this study was to evaluate how the risk of subjective memory worsening was changed after lowering stimulus dose during ECT for patients with major depression. METHOD A retrospective register-based intervention study of the effects of reduced electrical charges for patients receiving ECT for depression was conducted. The primary outcome was subjective memory worsening and the secondary outcome change in effect on depressive symptoms. RESULTS A total of 154 patients were enrolled in the study (High dosage group: n = 57; Lower dosage group: n = 97). Subjective memory worsening after ECT occurred in 44% of patients in the high dosage group and in 25% of patients in the lower dosage group(p = 0.014). There was no significant between-group difference in the anti-depressive effect of ECT. LIMITATIONS The study was register-based and the two groups were not randomized. A large portion of patients were initially excluded due to missing data in the register. The study lacks a long-term follow up. CONCLUSION After implementing a change of treatment protocol, that lowered ECT stimulus doses from high to moderate, the occurrence of subjective memory worsening was significantly reduced without compromising treatment results.

Abstract
Depression is one of the most disabling conditions in the world. In many cases patients continue to suffer with depressive disorders despite a series of adequate trials of medication and psychotherapy. Neuromodulation treatments offer a qualitatively different modality of treatment that can frequently prove efficacious in these treatment-refractory patients. The field of neuromodulation focuses on the use of electrical/electromagnetic energy, both invasively and noninvasively, to interface with and ultimately alter activity within the human brain for therapeutic purposes. These treatments provide another set of options to offer patients when clinically indicated, and knowledge of their safety, risks and benefits, and appropriate clinical application is essential for modern psychiatrists and other mental health professionals. Although neuromodulation techniques hold tremendous promise, only three such treatments are currently approved by the United States Food and Drug Administration (FDA) for the treatment of major depressive disorder: electroconvulsive therapy (ECT), vagus nerve stimulation (VNS), and repetitive transcranial magnetic stimulation (rTMS). Additionally, numerous other neurostimulation modalities (deep brain stimulation [DBS], magnetic seizure therapy [MST], transcranial electric stimulation [tES], and trigeminal nerve stimulation [TNS]), though currently experimental, show considerable therapeutic promise. Researchers are actively looking for ways to optimize outcomes and clinical benefits by making neuromodulation treatments safer, more efficacious, and more durable.

Abstract
Aims and methodFew studies have looked at subjective memory impairment from electroconvulsive therapy (ECT) after treatment completion. We aimed to systematically review all available evidence for subjective post-treatment effects. RESULTS: We included 16 studies in this review. There was considerable between-study heterogeneity in clinical population, ECT modality and assessment scales used. The most common assessment scale (eight studies) was the Squire Subjective Memory Questionnaire. The majority of studies reported an improvement in subjective memory after ECT, which correlated with improved depression scores. Subjective complaints were fewer in studies that used ultra-brief pulse ECT. Longer pulse widths were associated with more subjective complaints, as was female gender and younger age of treatment in the largest study.Clinical implicationsThere is considerable heterogeneity between studies, limiting meaningful conclusions. Ultra-brief pulse ECT appears to result in fewer subjective complaints.Declaration of interestNone.

Neurostimulation for depression in epilepsy. Epilepsy Behav 2018; 88S:25-32. [PMID: 30558717 DOI: 10.1016/j.yebeh.2018.06.007] [Citation(s) in RCA: 18] [Impact Index Per Article: 3.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 05/04/2018] [Revised: 05/31/2018] [Accepted: 06/03/2018] [Indexed: 01/02/2023]
Abstract
Epilepsy is often associated with comorbid psychiatric illnesses that can significantly impact its long-term course. The most frequent of these psychiatric comorbidities is major depressive disorder, which affects an estimated 40% of patients with epilepsy. Many patients are underdiagnosed or undertreated, yet managing their mood symptoms is critical to improving their outcomes. When conventional psychiatric treatments fail in the management of depression, neuromodulation techniques may offer promise, including electroconvulsive therapy (ECT), vagus nerve stimulation (VNS), and repetitive transcranial magnetic stimulation (rTMS), as discussed in this review.

Abstract
BACKGROUND Electroconvulsive therapy (ECT) is the most effective treatment for patients suffering from major depression. However, its use is limited due to concerns about negative effects on cognition. Unilateral ECT is associated with transient cognitive side-effects, while case-controlled studies investigating the effect of bilateral ECT on cognition remain scarce. We investigate the effects of bilateral ECT on cognition in depression in a longitudinal case-controlled study. We hypothesize that adverse cognitive effects of bilateral ECT are transient rather than long-term. METHODS A total of 48 depressed patients and 19 controls were included in the study and assessed with a battery of cognitive tests, including tests of: working memory, verbal fluency, visuospatial abilities, verbal/visual memory and learning, processing speed, inhibition, attention and task-switching, and premorbid IQ. Patients underwent three cognitive assessments: at baseline (n = 43), after ten ECT sessions (post-treatment; n = 39) and six months after the tenth ECT session (follow-up; n = 25). Healthy controls underwent the same cognitive assessment at baseline and after five-weeks. RESULTS Within the patient group, transient adverse cognitive side-effects were observed for verbal memory and learning, and verbal fluency. None of the cognitive domains tested in this study showed persisting impairments. LIMITATIONS A relatively high attrition rate is observed and autobiographical memory was not assessed. CONCLUSION This study shows that bilateral ECT has negative cognitive effects on short-term. These effects could be explained by a decrease in cognitive performance, a lack of learning effects or a combination. However, the decrease in cognitive functioning appears to recover after six months.

Abstract
BACKGROUND To determine event rates for specific medical events and mortality among individuals receiving electroconvulsive therapy (ECT). METHOD Population-based cohort study using health administrative data of acute ECT treatments delivered in Ontario, Canada, from 2003 to 2011. We measured the following medical event rates, per 10 000 ECT treatments, up to 7 and 30 days post-treatment: stroke, seizure, acute myocardial infarction, arrhythmia, pneumonia, pulmonary embolus, deep vein thrombosis, gastrointestinal bleeding, falls, hip fracture, and mortality. RESULTS A total of 135 831 ECT treatments were delivered to 8810 unique patients. Overall medical event rates were 9.1 and 16.8 per 10 000 ECT treatments respectively. The most common medical events were falls (2.7 and 5.5 per 10 000 ECT treatments) and pneumonia (1.8 and 3.8 per 10 000 ECT treatments). Fewer than six deaths occurred on the day of an ECT treatment. This corresponded to a mortality rate of less than 0.4 per 10 000 treatments. Deaths within 7 and 30 days of an ECT treatment, excluding deaths due to external causes (e.g., accidental and intentional causes of death), were 1.0 and 2.4 per 10 000 ECT treatments respectively. CONCLUSION Morbidity and mortality events after ECT treatments were relatively low, supporting ECT as a low-risk medical procedure.

Abstract
Although electroconvulsive therapy (ECT) remains the most effective treatment for severe depression, some patients report persistent memory problems following ECT that impact their quality of life and their willingness to consent to further ECT. While cognitive training has been shown to improve memory performance in various conditions, this approach has never been applied to help patients regain their memory after ECT. In a double-blind study, we tested the efficacy of a new cognitive training program called Memory Training for ECT (Mem-ECT), specifically designed to target anterograde and retrograde memory that can be compromised following ECT. Fifty-nine patients with treatment-resistant depression scheduled to undergo ultra-brief right unilateral ECT were randomly assigned to either: (a) Mem-ECT, (b) active control comprised of nonspecific mental stimulation, or (c) treatment as usual. Participants were evaluated within one week prior to the start of ECT and then again within 2 weeks following the last ECT session. All three groups improved in global function, quality of life, depression, and self-reported memory abilities without significant group differences. While there was a decline in verbal delayed recall and mental status, there was no decline in general retrograde memory or autobiographical memory in any of the groups, with no significant memory or clinical benefit for the Mem-ECT or active control conditions compared to treatment as usual. While we report negative findings, these results continue to promote the much needed discussion on developing effective strategies to minimize the adverse memory side effects of ECT, in hopes it will make ECT a better and more easily tolerated treatment for patients with severe depression who need this therapeutic option.

Abstract
Electroconvulsive therapy (ECT) is effective in the treatment of treatment-resistant major depression. The fear of cognitive impairment after ECT often deters patients from choosing this treatment option. There is little reliable information regarding the effects of ECT on overall cognitive performance, while short-term memory deficits are well known but not easy to measure within clinical routines. In this pilot study, we examined ECT recipients' pre- and post-treatment performances on a digital ascending number tapping test. We found that cognitive performance measures exhibited good reproducibility in individual patients and that ECT did not significantly alter cognitive performance up to 2 hours after this therapy was applied. Our results can help patients and physicians make decisions regarding the administration of ECT. Digital measurements are recommended, especially when screening for the most common side effects on cognitive performance and short-term memory.

Abstract
OBJECTIVE The aim of this study was to examine the effect of electroconvulsive therapy (ECT) on quality of life (QOL), depressive symptoms, and functioning for patients with depression, and to explore the variables related to QOL changes. METHODS Ninety-five inpatients with depression receiving at least 6 ECT sessions and completed all measures were included. Quality of life, symptom severity, and functioning were assessed using Short Form 36 (SF-36), the 17-item Hamilton Rating Scale for Depression (HAMD-17), and the Modified Work and Social Adjustment Scale (MWSAS), before and after ECT. The SF-36 includes 8 subscales, physical component summary (PCS), and mental component summary (MCS). Adverse effects after ECT, including headache, muscle pain, and nausea/vomiting, were also recorded. RESULTS All 8 SF-36 subscales, PCS, MCS, HAMD-17, and MWSAS improved significantly after treatment. Using multiple linear regression analysis, MWSAS changes predicted PCS changes significantly after adjusting for baseline PCS. Similarly, using multiple linear regression analysis, MWSAS changes were significant variables associated with MCS changes after adjusting for ECT frequency, HAMD-17 changes, and baseline MCS. The ECT improved QOL, depressive symptoms, and functioning. CONCLUSIONS Whether strategies to enhance functioning during an acute course of ECT could improve QOL is needed to be examined in a further study.

Abstract
OBJECTIVES The aims of the present study were to describe the short-term rate of subjective memory worsening (SMW) and identify factors of importance for SMW in a large clinical sample treated for depression with electroconvulsive therapy (ECT). METHODS This register-based study included 1212 patients from the Swedish National Quality Register for ECT. Subjective memory worsening was defined as a 2-point worsening on the memory item of the Comprehensive Psychopathological Rating Scale from before to within 1 week after treatment. Associations between patient characteristics and treatment factors were examined using logistic regression. RESULTS Subjective memory worsening was experienced in 26%. It was more common in women than in men (31% vs 18%; P < 0.001) and more common in patients aged 18 to 39 years than in patients 65 years or older (32% vs 22%; P = 0.008). Patients with less subjective memory disturbances before ECT had a greater risk of SMW. Patients in remission after ECT had a lower risk of SMW. A brief pulse width stimulus gave higher risk of SMW compared with ultrabrief pulse (odds ratio, 1.61; 95% confidence interval, 1.05-2.47). CONCLUSIONS Subjective memory worsening is reported by a minority of patients. However, young women are at risk of experiencing SMW. Ultrabrief pulse width stimulus could be considered for patients treated with unilateral electrode placement who experience SMW. Each patient should be monitored with regard to symptoms and adverse effects, and treatment should be adjusted on an individual basis to maximize the clinical effect and with efforts to minimize the cognitive adverse effects.

Abstract
OBJECTIVES Directly inquiring about patient experiences of memory problems after ECT may alert clinicians to the existence of treatment side effects and provide an impression of their intrusiveness. In this study, we examined use of a novel and brief patient-reported measure to assess perceptions of memory side effects and their functional consequences before and after an acute ECT treatment course. These outcomes were compared with objective cognitive and subjective quality of life measures. METHODS Data for 75 patients who were prescribed an acute course of ECT were analyzed. Subjective and objective measures were assessed before ECT (pretreatment) and at posttreatment. Patient perceptions were assessed using the Subjective Assessment of Memory Impairment, which consists of two items: The Memory Problems item, and The Impact of Cognitive Adverse Events item. Objective cognitive outcomes were assessed using the Montreal Cognitive Assessment. Quality of life was assessed using the Quality of Life Enjoyment and Satisfaction Questionnaire-Short Form. RESULTS Patient perceptions of their memory problems did not change across the ECT course, and their functional impact were considered less intrusive after ECT. Greater functional impact of memory impairment was related to poorer quality of life at posttreatment, but not at pretreatment. Subjectively rated cognitive functioning was not associated with objective cognitive outcomes. CONCLUSIONS The Subjective Assessment of Memory Impairment is a brief tool for measuring patient-rated memory function. Overall, patients did not report any change in subjective memory problems after ECT. Although perceptions of functional memory impairment and quality of life were related after ECT, there was no association with objectively assessed cognitive outcomes.

Abstract
OBJECTIVE The poor relationship between subjective and objective cognitive impairment in bipolar disorder (BD) is well-established. However, beyond simple correlation, this has not been explored further using a methodology that quantifies the degree and direction of the discrepancy. This study aimed to develop such a methodology to explore clinical characteristics predictive of subjective-objective discrepancy in a large BD patient cohort. METHODS Data from 109 remitted BD patients and 110 healthy controls were pooled from previous studies, including neuropsychological test scores, self-reported cognitive difficulties, and ratings of mood, stress, socio-occupational capacity, and quality of life. Cognitive symptom 'sensitivity' scores were calculated using a novel methodology, with positive scores reflecting disproportionately more subjective complaints than objective impairment and negative values reflecting disproportionately more objective than subjective impairment ('stoicism'). RESULTS More subsyndromal depressive and manic symptoms, hospitalizations, BD type II, and being male positively predicted 'sensitivity', while higher verbal IQ predicted more 'stoicism'. 'Sensitive' patients were characterized by greater socio-occupational difficulties, more perceived stress, and lower quality of life. CONCLUSION Objective neuropsychological assessment seems especially warranted in patients with (residual) mood symptoms, BD type II, chronic illness, and/or high IQ for correct identification of cognitive deficits before commencement of treatments targeting cognition.

Abstract
BACKGROUND Cognitive side effects may occur after electroconvulsive treatment (ECT) in depressive disorder patients. Previous studies have been limited by small numbers of cognitive functions assessed. The present study reports the first results from a prospective project monitoring cognitive effects of ECT using a comprehensive neuropsychological test battery and subjective report of everyday cognitive function. METHODS Thirty-one patients with major depressive disorder were assessed with the MATRICS Consensus Cognitive Battery (MCCB). Subjective cognitive complaints were described with the Everyday Memory Questionnaire (EMQ). Severity of depression symptoms were assessed with the Montgomery-Åsberg Depression Rating Scale (MADRS). These assessments were performed prior to and 6 weeks after non-standardized ECT. RESULTS Compared to baseline, the mean depression severity level was nearly halved and there were significant improvements in mean levels of Speed of Processing, Attention/Vigilance, and Visual Learning 6 weeks after ECT. The other cognitive domains were not altered from baseline. There was no significant change in subjective cognitive complaints. At baseline, there were several significant correlations between the MADRS and MCCB scores. There was no strong association between the EMQ and MCCB scores at either assessment point, but the post-ECT EMQ score was significantly correlated with depression severity. LIMITATIONS Major limitations were low N and lack of uniform ECT procedure. CONCLUSIONS There was significant improvement in Speed of Processing, Attention/Vigilance, and Visual Learning 6 weeks after ECT. Cognitive tests scores were related to severity of depression, but not to subjective memory complaints.

Abstract
OBJECTIVE Late-life depression (LLD) is known to negatively impact cognition even after remission of mood symptoms. Electroconvulsive therapy (ECT) and newer nonconvulsive electrical and magnetic brain stimulation interventions have been shown to have cognitive effects in patients with neuropsychiatric disorders. METHODS This review systematically assessed the effects of ECT on cognition in LLD. EMBASE, Ovid Medline, and PsycINFO were systematically searched through June 2015. The search was limited to publications from peer-reviewed journals in the English language. RESULTS A total of 5,154 publications was identified; 318 were reviewed in full text, of which 39 publications related to ECT were included. We focused this review only on ECT because evidence on newer interventions was deemed insufficient for a systematic review. This literature suggests increased rates of interictal and postictal cognitive decline with ECT but no long-term (i.e., 6 months or longer) deleterious effects on cognition. Instead, long-term cognitive outcomes with ECT have been reported as either not changed or improved. This literature favors nondominant unilateral ECT over bilateral ECT for cognition. CONCLUSION Published literature on brain stimulation interventions in LLD is mainly limited to ECT. This literature suggests that deleterious effects of ECT in LLD are limited and transient, with better cognitive outcomes with unilateral ECT. There is not enough evidence to fully characterize long-term deleterious effects of ECT or effects of newer brain stimulation techniques on cognition in LLD.

Abstract
BACKGROUND The MATRICS Consensus Cognitive Battery (MCCB) was developed for schizophrenia patients, but is also being used to assess neurocognitive function in bipolar disorder. This study aims to describe neurocognitive differences in major depressive disorder patients and healthy controls with the MCCB, and to describe the relationship between depression symptom severity, subjective cognitive complaints, and objective cognitive test performance. METHODS Thirty-three patients with major depressive disorder and 33 pairwise matched healthy controls were assessed with the MCCB. The patients were also assessed with the Montgomery-Åsberg Depression Rating Scale (MADRS) and the Everyday Memory Questionnaire (EMQ). RESULTS On all neurocognitive domains, the depression patients scored significantly lower than the controls. The level of impairment ranged from 21.0% (Working Memory) to 58.0% (Speed of Processing). There were significant associations between neurocognitive test performance and depression symptom severity, but not with subjective cognitive complaints. CONCLUSIONS The MCCB was applicable in this study of major depressive disorder, and revealed significant neurocognitive dysfunction in this group. At least one fifth of the patients were impaired on all cognitive domains, with Speed of Processing and Reasoning/Problem Solving being most strongly affected. The objective test scores were significantly related to depression severity, but not to subjective cognitive complaints.

Abstract
CONTEXT Although electroconvulsive therapy (ECT) is considered a very effective tool for the treatment of psychiatric diseases, memory disturbances are among the most important adverse effects. AIMS This study aimed to assess prospectively early subjective memory complaints in depressive and manic patients due to bilateral, brief-pulse ECT, at different stages of the treatment, compare the associations between psychiatric diagnosis, sociodemographic characteristics, and ECT characteristics. SETTINGS AND DESIGN This prospective study was done with patients undergoing ECT between November 2008 and April 2009 at a tertiary care psychiatry hospital of 2000 beds. MATERIALS AND METHODS A total of 140 patients, scheduled for ECT with a diagnosis of bipolar disorder (depressive or manic episode) or unipolar depression according to Diagnostic and Statistical Manual of Mental Disorders IV diagnostic criteria, were included in the study and invited to complete the Squire Subjective Memory Questionnaire (SSMQ) before ECT, after the first and third sessions and end of ECT treatment. STATISTICAL ANALYSIS Mean values were compared with the Kruskal-Wallis test and comparison of the longitudinal data was performed with a nonparametric longitudinal data analysis method, F1_LD_F1 design. RESULTS SSMQ scores of the patients before ECT were zero. SSMQ scores showed a decrease after the first and third ECT sessions and before discharge, showing a memory disturbance after ECT and were significantly less severe in patients with mania in comparison to those with depression. CONCLUSIONS These findings suggest an increasing degree of subjective memory complaints with bilateral brief-pulse ECT parallel to the increasing number of ECT sessions.

Abstract
Both impaired and improved cognitive function after electroconvulsive therapy (ECT) in major depressive disorder (MDD) patients may occur. We have previously found improved cognitive function 6 weeks after ECT in this group. The aim of this study was to report 6-month follow-up results from the same prospective project monitoring cognitive effects of ECT. Thirty-one patients with MDD were assessed with the MATRICS Consensus Cognitive Battery (MCCB), the Everyday Memory Questionnaire (EMQ), and the Montgomery-Åsberg Depression Rating Scale prior to, 6 weeks, and 6 months after ECT. Compared to baseline, the speed of processing, attention/vigilance, and reasoning/problem solving test results were significantly improved. The depression score was significantly reduced. There were no changes in subjective memory complaint. There was no significant relationship between the EMQ and the MCCB subtests, but a significant correlation between current depression level and the EMQ. Six months after ECT the cognitive improvement reported at 6-week follow-up was maintained and extended. The corresponding decrease in depressive symptoms and stability in subjectively reported memory complaints suggest that the antidepressant effects of ECT do not occur at the expense of cognitive function.

Abstract
UNLABELLED Objective. Magnetic seizure therapy (MST) is a novel, experimental therapeutic intervention, which combines therapeutic aspects of electroconvulsive therapy (ECT) and transcranial magnetic stimulation, in order to achieve the efficacy of the former with the safety of the latter. MST might prove to be a valuable tool in the treatment of mood disorders, such as major depressive disorder (MDD) and bipolar disorder. Our aim is to review current literature on MST. Methods. OVID and MEDLINE databases were used to systematically search for clinical studies on MST. The terms "magnetic seizure therapy," "depression," and "bipolar" were employed. Results. Out of 74 studies, 8 met eligibility criteria. There was considerable variability in the methods employed and samples sizes were small, limiting the generalization of the results. All studies focused on depressive episodes, but few included patients with bipolar disorder. The studies found reported significant antidepressant effects, with remission rates ranging from 30% to 40%. No significant cognitive side effects related to MST were found, with a better cognitive profile when compared to ECT. CONCLUSION MST was effective in reducing depressive symptoms in mood disorders, with generally less side effects than ECT. No study focused on comparing MST to ECT on bipolar depression specifically.

Abstract
Early studies of transcranial magnetic stimulation (TMS) have shown no adverse effects on neuropsychological function. However, further research using higher TMS intensities as well as a greater number of TMS pulses and with larger sample sizes is needed. We studied 68 patients with major depressive disorder who were randomized to receive either 15 sessions of sham or real TMS at 110% of the estimated prefrontal cortex threshold to the left dorsolateral prefrontal cortex. Each session consisted of 32 5-second trains of 10-Hz repetitive TMS at 110% adjusted motor threshold. A total of 24,000 pulses were given. Neuropsychological function was assessed before and immediately after TMS treatment with a battery of 8 tests. Using a higher TMS intensity as well as a greater number of pulses and having a larger sample size compared with most previous studies, this study found no negative neuropsychological effects of TMS. Changes in neuropsychological function were unrelated to changes in depression.

Abstract
BACKGROUND Electroconvulsive therapy (ECT) is an effective treatment for depression but the extent and persistence of cognitive side-effects remain uncertain. It has been reported that there is little evidence that impairments last longer than up to 15 days post-ECT. However, relatively few studies have followed patients for even as long as 1 month post-ECT. Here we report results from a brief cognitive battery given prior to ECT and repeated five times up to 6 months post-ECT. METHOD In a retrospective case-note study of routinely collected clinical data 126 patients treated with ECT completed two neuropsychological tests [Cambridge Neuropsychological Test Automated Battery (CANTAB) spatial recognition memory (SRM) and Mini Mental State Examination (MMSE)] and two subjective reports of memory function, prior to ECT. Patients were reassessed following ECT and at 1, 3 and 6 months post-ECT although not all patients completed all assessments. RESULTS Performance relative to pre-ECT baseline was significantly poorer at each post-ECT assessment up to 3 months post-ECT using the CANTAB SRM, but was improved at 6 months. Conversely, MMSE score showed improvements relative to baseline from 1 month post-ECT. Mood and subjective memory scores improved following ECT and were correlated with one another, but not with either neuropsychological measure. CONCLUSIONS The CANTAB SRM task revealed reversible cognitive deficiencies relative to a pre-ECT baseline for at least 3 months following ECT, while MMSE score and patients' subjective reports showed only improvement. Visuospatial memory scores eventually exceeded baseline 6 months post-ECT.

Abstract
Retrograde amnesia for autobiographical information is the most critical adverse effect of electroconvulsive therapy (ECT). Much, if not most, modern research demonstrating long-term autobiographical amnesia after ECT has used either the Columbia University Autobiographical Memory Interview (CUAMI) or the short form of this scale (CUAMI-SF). Semkovska and McLoughlin claimed that studies using these instruments should be dismissed and the findings ignored owing to a lack of normative data, as well as concerns about the reliability and validity of these instruments. In this commentary, the development and use of these scales is reviewed. It is shown that Semkovska and McLoughlin's critique is factually incorrect, as normative data were simultaneously collected in virtually all studies using these instruments. Furthermore, there is substantial evidence supporting the reliability and validity of these scales. Indeed, these instruments are the only neuropsychological tests repeatedly shown to covary with patient self-evaluations of ECT's effects on memory and have repeatedly demonstrated long-term differences in the magnitude of amnesia as a function of ECT technique. Findings with the CUAMI and CUAMI-SF provide key evidence regarding ECT's adverse cognitive effect profile. It is inaccurate and inadvisable to continue to deny that ECT can exert long-term adverse effects in this domain.

Abstract
OBJECTIVE In a previous magnetic resonance imaging (MRI) study, we found a significant increase in hippocampal volume immediately after electroconvulsive therapy (ECT) in patients with depression. The aim of this study was to evaluate hippocampal volume up to 1 year after ECT and investigate its possible relation to clinical and cognitive outcome. METHOD Clinical and cognitive outcome in 12 in-patients with depression receiving antidepressive pharmacological treatment referred for ECT were investigated with the Montgomery-Asberg Depression Rating Scale (MADRS) and a broad neuropsychological test battery within 1 week before and after ECT. The assessments were repeated 6 and 12 months after baseline in 10 and seven of these patients, respectively. Hippocampal volumes were measured on all four occasions with 3 Tesla MRI. RESULTS Hippocampal volume returned to baseline during the follow-up period of 6 months. Neither the significant antidepressant effect nor the significant transient decrease in executive and verbal episodic memory tests after ECT could be related to changes in hippocampal volume. No persistent cognitive side effects were observed 1 year after ECT. CONCLUSION The immediate increase in hippocampal volume after ECT is reversible and is not related to clinical or cognitive outcome.

Abstract
Electroconvulsive therapy (ECT) is utilized worldwide for various severe and treatment-resistant psychiatric disorders. Research studies have shown that ECT is the most effective and rapid treatment available for elderly patients with depression, bipolar disorder and psychosis. For patients who suffer from intractable catatonia and neuroleptic malignant syndrome, ECT can be life saving. For elderly patients who cannot tolerate or respond poorly to medications and who are at a high risk for drug-induced toxicity or toxic drug interactions, ECT is the safest treatment option. Organic causes are frequently associated with late-life onset of neuropsychiatric conditions, such as parkinsonism, dementia and stroke. ECT has proven to be efficacious even when these conditions are present. During the next decade, research studies should focus on the use of ECT as a synergistic therapy, to enhance other biological and psychological treatments, and prevent symptom relapse and recurrence.

Abstract
Zolpidem is the most commonly prescribed medication for the short-term treatment of insomnia. Adverse reactions include nightmares, confusion, and memory deficits. Reported rare adverse neuropsychiatric reactions include sensory distortions such as hallucinations. Previous research has identified 4 factors that may place a patient at increased risk of zolpidem-associated psychotic or delirious reactions: (1) concomitant use of a selective serotonin reuptake inhibitor (SSRI), (2) female gender, (3) advanced age, and (4) zolpidem doses of 10 mg or higher. In this article, 2 cases are presented in which individuals killed their spouses and claimed total or partial amnesia. Neither individual had a history of aggressive behavior. Both had concomitantly taken 10 mg or more of zolpidem in addition to an SSRI (paroxetine).

Abstract
Somatic treatments for mood disorders represent a class of interventions available either as a stand-alone option, or in combination with psychopharmacology and/or psychotherapy. Here, we review the currently available techniques, including those already in clinical use and those still under research. Techniques are grouped into the following categories: (1) seizure therapies, including electroconvulsive therapy and magnetic seizure therapy, (2) noninvasive techniques, including repetitive transcranial magnetic stimulation, transcranial direct current stimulation, and cranial electric stimulation, (3) surgical approaches, including vagus nerve stimulation, epidural electrical stimulation, and deep brain stimulation, and (4) technologies on the horizon. Additionally, we discuss novel approaches to the optimization of each treatment, and new techniques that are under active investigation.

Abstract
OBJECTIVES Using standard self-evaluation questionnaires, numerous studies have found that subjective memory improves shortly after electroconvulsive therapy (ECT). This change covaries strongly with depression severity and is not associated with objective amnestic effects or treatment parameters. We examined subjective evaluations of ECT's cognitive effects using a novel interview that directly inquired about global impact, in contrast to the standard method of inquiring about specific aspects of cognition. METHODS We conducted a prospective, randomized, double-masked trial comparing the effects of pulse width (0.3 vs 1.5 milliseconds) and electrode placement (right unilateral vs bilateral) on cognitive outcomes. Subjective evaluations were obtained before and during the week after the randomized ECT course, using the Cognitive Failures Questionnaire, the Squire Memory Complaint Questionnaire, and the novel Global Self-Evaluation of Memory. An extensive neuropsychological battery was administered at these time points. RESULTS Cognitive Failures Questionnaire and Squire Memory Complaint Questionnaire scores improved at post-ECT relative to pre-ECT, strongly covaried with depression severity (24-item Hamilton Depression Rating Scale scores) but not with objective amnestic deficits or treatment parameters. In contrast, the treatment conditions differed in post-ECT Global Self-Evaluation of Memory scores, and these scores were associated with objective amnestic effects. CONCLUSIONS In contrast to standard methods, direct questioning about global impact resulted in more negative views about ECT's cognitive effects, concordance with objective cognitive measures, and differences among treatment conditions. Patients may be more accurate in their assessment of ECT's adverse effects than had previously been suggested.

Abstract
OBJECTIVE To provide more insight into subjective attention complaints in a healthy adult and elderly population and how these affect Quality of Life (QoL). METHOD A group of 1,550 healthy Dutch participants complete a postal questionnaire including items from the Maastricht Attention and Memory Checklist (MAC). The impact of attention complaints on QoL is investigated in a subsample of 499 participants. RESULTS Factor analysis (N = 1,550) reveals two factors: Attention and Memory. Attention complaints are related to depressed mood, anxiety, vitality, and sleep problems that can have serious consequences for daily life functioning and QoL (n = 499). Memory complaints are related to other aspects of health, such as pain and changes in health. CONCLUSION Attention complaints in the healthy population are common and related to depression, anxiety, and sleep and several aspects of QoL, such as problems with social functioning, emotional problems, and vitality.

Abstract
OBJECTIVE The cognitive side-effects of bifrontal (BF) and right unilateral (UL) ultra-brief pulse (0.3 ms) electroconvulsive therapy (ECT) were compared, in the treatment of patients with a depressive episode. METHOD Neuropsychological functioning in patients with a medication refractory depressive episode, that were treated with a course of BF ultra-brief ECT at 1.5 times seizure threshold (ST) or UL ultra-brief ECT at 6 times ST, by random assignment, was assessed before treatment, and 1 and 6 weeks after the treatment course, by a blinded rater. RESULTS Of the 64 patients that were included, 32 (50%) received BF ECT, and 32 (50%) received UL ECT, by random assignment. Neuropsychological testing 1 and 6 weeks after treatment was performed by 30 (93.75%) and 19 (59.37%) patients, respectively, in the BF-group and 29 (90.62%) and 20 (62.50%), respectively, in the UL-group. There was no deterioration in any of the neuropsychological measures. Patients rated their memory as clearly improved after treatment. There were no significant differences between the patients given BF ECT and those given UL ECT. CONCLUSIONS Ultrabrief pulse ECT, used either in combination with a UL electrode position and a stimulus of 6 times ST, or a BF electrode position with a stimulus of 1.5 times ST, are effective antidepressant techniques, that do not have a deleterious effect on cognitive function.

Abstract
OBJECTIVE Bilateral (BL) electrode placement delivered at 2.5 times the initial seizure threshold (ST; 2.5 x ST) is the gold standard method for seizure delivery during electroconvulsive therapy (ECT). However, there is a growing interest in using a high dose (6 x ST) with ultrabrief right unilateral (UB-RUL) electrode placement to reduce the incidence of possible short-term memory problems associated with BL ECT. Although studies have found UB-RUL ECT to have similar effectiveness to BL ECT, the objective of this study was to determine potential differences in efficiency (ie, the number of treatments needed to reach remission). METHODS Electroconvulsive therapeutic data for 56 patients with depression treated during 2006 and 2007 were analyzed via retrospective chart review. A total of 26 patients were started on UB-RUL ECT, whereas 30 patients were started on brief pulse BL ECT. RESULTS The patients started on high-dose UB-RUL ECT required significantly more treatments than the patients started on BL ECT (9.4 [3.3] vs 7.7 [2.8] treatments). Of the 26 patients started on UB-RUL ECT, 12 (46%) experienced a lack of effectiveness and/or insufficient seizure induction and were thus switched to BL ECT; the 8 patients switched because of lack of effectiveness received a mean (SD) of 12.2 (2.9) treatments, whereas the 4 patients switched because of insufficient seizure induction received a mean (SD) of 11.3 (3.6) treatments. CONCLUSIONS These findings add to an emerging story of reduced efficiency of UB-RUL versus BL electrode placement for an index course of ECT for the treatment of depression.

Abstract
The concept of inducing convulsions, mainly through chemical means, to promote mental wellness has existed since the 16th century. In 1938, Italian scientists first applied electrically induced therapeutic seizures. Although electroconvulsive therapy (ECT) is employed in the treatment of several psychiatric disorders, it is most frequently used today to treat severe depressive episodes and remains the most effective treatment available for those disorders. Despite this, ECT continues to be the most stigmatized treatment available in psychiatry, resulting in restrictions on and reduced accessibility to a helpful and potentially life-saving treatment. The psychiatric and psychosocial ramifications of this stigmatization may include the exacerbation of the increasingly serious, global health problem of major depressive disorders as well as serious consequences for individual patients who may not be offered, or may refuse, a potentially beneficial treatment. The goal of this first article in this two-part series is to provide an overview of ECT's historical development and discuss the current state of knowledge about ECT, including technical aspects of delivery, patient selection, its side-effect profile, and factors that may contribute to underuse of ECT.

Abstract
OBJECTIVES In the last 20 years, an increasing number of articles have been published about effects of electroconvulsive therapy (ECT) on memory. Here, we review autobiographical memory studies in particular because there have been conflicting reports about the extent and persistence of ECT effects and the period before treatment from which memories are most likely to be affected. METHODS Five psychological and medical databases (MEDLINE, PubMed, PsychINFO, ScienceDirect, and Web of Knowledge) were searched from 1980 to 2007, yielding 15 studies of ECT and autobiographical memory. RESULTS Evidence suggests that autobiographical memory impairment does occur as a result of ECT. Objective measures found memory loss to be relatively short term (<6 months posttreatment), whereas subjective accounts reported amnesia to be more persistent (>6 months post-ECT). Electroconvulsive therapy predominantly affects memory of prior personal events that are near the treatment (within 6 months). Autobiographical memory loss is reduced by using brief pulse ECT rather than sine wave-unilateral positioning of electrodes rather than bilateral-and by titrating electrical current relative to the patient's own seizure threshold. CONCLUSIONS Further research is required to determine memory loss associated with ECT, controlling for the direct effects of the depressive state.

Abstract
This article explores the subjective experience of cognitive deficits of patients who are treated with electroconvulsive therapy, by using actual comments made in clinical situations. The material is divided into 4 themes: the need for clear information, the importance of validation of experience, the impact of daily disruptions, and the issue of self-esteem. It is argued that despite the low correlation which exists between objectively measured cognitive function and the subjectively experienced impairment, the discrepancy creates a need to take both perspectives into consideration rather than to rely on one or the other. The validity and limitations of using personal narrative as a relevant clinical parameter are discussed.

Abstract
OBJECTIVE To review studies that examined the impact of electroconvulsive therapy (ECT) on cognitive functioning in depressed older people. METHODS Studies were systematically retrieved using PsychINFO and MEDLINE, with additional articles sourced from lists of references. Given our aged-care focus, study participants had a minimum mean age of 60 years, with no single participant younger than 50 years. RESULTS Twenty-seven studies met our criteria. Apart from evidence of interictal slowing of information processing speed, there were mixed results with regard to the impact of ECT on other cognitive domains. Factors contributing to this variability in results include the lack of discrimination between unilateral, bilateral, or mixed electrode placement; the inclusion of patients with dementia; the small sample sizes; and the use of tests insensitive to subtle cognitive changes. CONCLUSIONS The effect of ECT in elderly recipients' cognition remains unclear, and further research with more critically selected methods is required. In the meantime, we recommend that clinicians regularly administer brief focused cognitive tests before, during, and after treatment to monitor progress.

Abstract
Cognitive impairment is the most important side effect of electroconvulsive therapy (ECT), and if detected early, modifications to treatment can be made to reduce the severity of it. Various guidelines suggest that regular, detailed monitoring of cognitive function should be routine during ECT. We hypothesize that such monitoring would be able to detect cognitive effects of ECT at an early stage but that this would require careful selection of tests to be both sensitive and practical in routine clinical practice. We review evidence regarding the sensitivity of various cognitive tests to the effects of ECT. From this, we suggest a battery and testing schedule which may be both practical and useful in early detection of the cognitive effects of ECT.
