Decision-making Capacity for Treatment After Electroconvulsive Therapy for Depression.

OBJECTIVES: Depression can impair decision-making capacity (DMC) for health care decisions. However, it is unclear whether DMC improves after treatments for depression such as electroconvulsive therapy (ECT). There is limited evidence available on DMC for treatment in patients with depression referred for ECT, and it is unknown whether ECT has any impact on DMC. We hypothesized that ECT will improve DMC in severely depressed patients and that this change will be associated with reduced depressive symptom severity. METHODS: Using the MacArthur Competence Assessment Tool-Treatment, 4 abilities related to DMC were evaluated: Understanding, Appreciation, Reasoning, and Expressing a choice. This prospective study compared DMC abilities, depression severity, and cognition scores in 24 patients hospitalized with a major depressive episode before and 3 to 5 days after a course of ECT. RESULTS: Although Understanding scores significantly improved after ECT (P = 0.004, r = 0.41), there was no change in other abilities related to DMC or cognition scores. As expected, there was a large improvement in mood ratings after ECT, but the change in DMC abilities was not associated with change in depressive symptoms. CONCLUSIONS: To our knowledge, this is the first study to provide data on the effects of ECT on DMC in patients with depression. Abilities related to DMC that may be affected in this group before treatment include Understanding and Reasoning. Findings indicate that DMC to consent to treatment mostly does not change after a course of ECT and some aspects can improve in patients with depression.

A randomized controlled trial of cognitive remediation for a national cohort of forensic patients with schizophrenia or schizoaffective disorder.

BACKGROUND: Evidence is accumulating that Cognitive Remediation Training (CRT) is effective for ameliorating cognitive deficits experienced by patients with schizophrenia and accompanying functional impairment. There has been no randomized controlled trial of CRT using a nationally representative population of forensic patients, despite the significant cognitive deficits frequently present within this group. METHODS: Sixty-five patients with schizophrenia or schizoaffective disorder were enrolled in a single blind randomized controlled trial of CRT versus treatment as usual (TAU); representing 94% of those eligible within a national forensic cohort. The primary outcome measure was the composite score of the MATRICS Consensus Cognitive Battery (MCCB). Secondary outcome measures included neurocognitive and social cognitive domains, symptoms, and 'real world' functioning. Patient satisfaction was examined using an exit interview. Participants were reassessed at 8 months follow up. All data were analyzed using an intention to treat design (ITT). RESULTS: For the primary outcome measure, the MCCB composite score, there were significant differences between those who participated in CRT and those receiving TAU at both end of treatment and 8 months follow up (Cohen's d = 0.34. Significant improvements were observed in visual and working memory. Mediation analysis found that those who cognitively benefited from CRT had corresponding improved functioning, and more net positive therapeutic moves i.e. moves to units with lower security within the hospital. Ninety-six percent believed their cognitive gains positively affected their daily lives. CONCLUSIONS: CRT may be an acceptable and efficacious intervention for forensic patients with schizophrenia or schizoaffective disorder.

Ketamine Versus Midazolam for Depression Relapse Prevention Following Successful Electroconvulsive Therapy: A Randomized Controlled Pilot Trial.

OBJECTIVE: Depression relapse after electroconvulsive therapy (ECT) is common (40% at 6 months). Ketamine has a robust antidepressant effect, but there are no reported studies of ketamine for depression relapse prevention. This pilot trial (NCT02414932) was designed to assess feasibility of the proposed trial protocol, including examining reasons for nonrecruitment, nonrandomization, and dropout. METHODS: Patients with unipolar depression referred for ECT were monitored weekly for therapeutic response, using the 24-item Hamilton Rating Scale for Depression (monitoring phase). Those who met standard response criteria were invited to be randomized to a course of 4 once-weekly infusions of ketamine (0.5 mg/kg) or the active comparator, midazolam (0.045 mg/kg), over 40 minutes to examine trial processes (treatment phase). Participants were followed up for 6 months after ECT to assess for relapse. RESULTS: One hundred seventy-five referrals were screened over 18 months, and 68% of eligible participants (n = 43) were recruited to the monitoring phase; 60.5% of participants met ECT response criteria (n = 26), but only 26% (6) of these consented to take part in the treatment phase. These were randomized (3 to ketamine and 3 to midazolam), and no participant completed the 4-week treatment protocol. Information was gathered on reasons for nonrecruitment, nonrandomization, and dropout, which included practical aspects of infusions and lack of interest in further treatment after response to ECT. CONCLUSIONS: The proposed treatment protocol is not suitable for a definitive trial in our center. Information collected on reasons for dropout may inform future clinical trials of intravenous ketamine. TRIAL REGISTRATION: www.clinicaltrials.gov NCT02414932.

Attitudes and perceptions of Irish health care professionals regarding functional neurological disorder: A national survey.

BACKGROUND: Functional neurological disorder (FND) is a common and often disabling condition. Limited access to services for FND poses challenges both for patients and their health care providers. This survey explored the attitudes, experiences, support needs and training needs of health care professionals (HCPs) who provide care to individuals with FND in Ireland. METHODS: A broad range of HCPs working with patients with FND in Ireland partook in an anonymous online 12-item survey. Participants were recruited via professional bodies and snowball convenience sampling utilising social media and email invitation. Descriptive and inferential statistics were employed to analyze data. RESULTS: A total of 314 HCPs working in Ireland completed the survey. 80% were female and over half worked in their current role for more than 10 years.   75% of the sample encountered three or less individuals with FND per month. Identified service-related challenges to effective patient care included insufficient clinic time, lack of confidence explaining the diagnosis, and the need for greater access to specialist support.  Data revealed persisting negative attitudes toward FND patients among a proportion of respondents. The majority of respondents did not feel they received adequate education on FND, with the exception of neurologists, of whom 65% felt adequately trained.  The majority of respondents (85%) also felt that people with FND did not have access to appropriate FND services in Ireland. CONCLUSION: This study indicates that there is a significant need to improve FND education among HCPs in Ireland, in addition to developing appropriately resourced, integrated, multidisciplinary care pathways for the FND patient group.

The magic hand: Plasticity of mental hand representation.

Internal spatial body configurations are crucial to successfully interact with the environment and to experience our body as a three-dimensional volumetric entity. These representations are highly malleable and are modulated by a multitude of afferent and motor information. Despite some studies reporting the impact of sensory and motor modulation on body representations, the long-term relationship between sensory information and mental representation of own body parts is still unclear. We investigated hand representation in a group of expert sleight-of-hand magicians and in a group of age-matched adults naïve to magic (controls). Participants were asked to localise landmarks of their fingers when their hand position was congruent with the mental representation (Experiment 1) and when proprioceptive information was "misleading" (Experiment 2). Magicians outperformed controls in both experiments, suggesting that extensive training in sleight of hand has a profound effect in refining hand representation. Moreover, the impact of training seems to have a high body-part specificity, with a maximum impact for those body sections used more prominently during the training. Interestingly, it seems that sleight-of-hand training can lead to a specific improvement of hand mental representation, which relies less on proprioceptive information.
