What therapeutic intervention is indicated for treatment-resistant psychiatric/aggressive symptoms in a patient with CTE and a comorbid primary psychotic disorder?
What is the next step in treating a primary psychotic illness with aggression when high-dose/high-level clozapine treatment only provides a partial response?
Relapse following electroconvulsive therapy (ECT) remains a significant clinical challenge despite continuation of pharmacotherapy. We performed a systematic review and meta-analysis (PROSPERO CRD420251000113) of the efficacy and acceptability of continuation ECT (cECT) combined with pharmacotherapy compared to pharmacotherapy alone for relapse prevention following an acute course of ECT for depression. We searched PubMed, Embase, Web of Science, and CENTRAL databases for randomized controlled trials enrolling adults diagnosed with a unipolar or bipolar major depressive episode, who met remission or response criteria after an acute course of ECT and who were subsequently randomized to cECT with pharmacotherapy versus pharmacotherapy alone. The efficacy outcome was the cumulative relapse rate at 6-month follow-up. Data were synthesized using random-effects meta-analyses with effect sizes expressed as relative risks (RRs) with 95% confidence intervals (CIs). Four trials (n = 254) met the inclusion criteria. cECT combined with pharmacotherapy significantly reduced relapse compared to pharmacotherapy alone (RR = 0.57, 95% CI = 0.37–0.88; I2 = 0%; number needed to treat = 7). Sensitivity analyses consistently supported the superiority of cECT under all examined dropout scenarios and analytic approaches. Acceptability, measured by all-cause dropout, was similar between the groups (RR = 1.12; 95% CI = 0.48–2.62; I2 = 0%). cECT combined with pharmacotherapy significantly reduces the RR of relapse by 43% compared to pharmacotherapy alone without compromising acceptability. These findings reinforce the role of cECT as a valuable relapse prevention strategy following successful acute ECT and highlight the need for larger, multicenter trials to further optimize post-ECT prophylaxis.
This chapter explores the diverse therapeutic approaches to catatonia, integrating insights from both national and international guidelines. The primary treatment typically include benzodiazepines, such as lorazepam and diazepam, which are widely recognized for their efficacy in alleviating catatonic symptoms. Electroconvulsive therapy (ECT) remains a cornerstone for more severe, treatment-resistant and malignant cases (e.g. febrile catatonia), with recent evidence suggesting its effectiveness across various psychiatric populations, including children, adolescents, older adults, and patients with dementia. However, in cases of ultra-resistant catatonia – where up to 40% of patients do not respond to benzodiazepines or ECT – new treatment options such as intranasal esketamine are emerging, showing promise in cases unresponsive to conventional therapies. Additionally, treatments such as dopamine receptors antagonists and partial agonists (=antipsychotics) must be used with caution, particularly in cases of substance-induced catatonia, where they may exacerbate symptoms. Noninvasive brain stimulation techniques like repetitive transcranial magnetic stimulation and transcranial direct current stimulation are also gaining attention for their potential therapeutic benefits in catatonia, though further research is needed. Finally, the chapter underscores the importance of individualized treatment plans, carefully considering the underlying cause of catatonia to optimize outcomes and ensure the most effective intervention.
Electroconvulsive therapy (ECT) is often used to treat severe mental disorders in individuals with impaired capacity to consent to the treatment. Little is known about how different types of electrode placement are used in consensual and nonconsensual ECT.
Aims
To investigate whether there was an association between ECT consent status and electrode placement, given that ECT electrode placement affects efficacy and cognitive outcomes.
Method
Using a statewide database across 3 years in Victoria, Australia, we performed chi-squared tests to determine whether consent status (consensual versus nonconsensual) was associated with particular electrode placements. A three-way log–linear analysis was then conducted to examine whether age, gender, level of education and psychiatric diagnosis influenced the relationship between consent status and electrode placement. Given the comparable cognitive outcomes of right unilateral and bifrontal ECT, these electrode placements were combined in the analysis.
Results
In total, 3882 participants received ECT in the Victorian public health service during the study period. In the nonconsensual ECT group, 722 of 1576 individuals (45.81%) received bitemporal ECT, compared with 555 of 2306 (24.06%) in the consensual group (χ2 = 200.53; P < 0.0001; odds ratio: 2.6673, 95% CI: 2.3244–3.0608). This association remained significant after adjustment for gender, age, level of education and diagnosis.
Conclusion
Significantly more participants in the nonconsensual ECT group received bitemporal ECT rather than right unilateral or bifrontal ECT compared with those in the consensual group. As bitemporal ECT is associated with more cognitive impairment, this choice of electrode placement in vulnerable patients who lack capacity to consent raises ethical considerations in the practice of ECT.
Older people with depression exhibit better response to electroconvulsive therapy (ECT). We aimed to measure the total effect of age on ECT response and investigate whether this effect is mediated by psychotic features, psychomotor retardation, psychomotor agitation, age of onset, and episode duration.
Methods
We pooled data from four prospective Irish studies where ECT was administered for a major depressive episode (unipolar or bipolar) with baseline score ≥21 on the 24-item Hamilton Depression Rating Scale (HAM-D). The primary outcome was change in HAM-D between baseline and end of treatment. The estimands were total effect of age, estimated using linear regression, and the indirect effects for each putative mediator, estimated using causal mediation analyses.
Results
A total of 256 patients (mean age 57.8 [SD = 14.6], 60.2% female) were included. For every additional 10 years of age, HAM-D was estimated to decrease by a further 1.74 points over the ECT period (p < 0.001). Age acted on all putative mediators. Mechanistic theories, whereby a mediator drives treatment response, were confirmed for all putative mediators except age of onset. Consequently, mediation of the effect of age on change in HAM-D could be demonstrated for psychotic features, psychomotor retardation, psychomotor agitation, and episode duration but not for age of onset.
Conclusions
A total of 43.1% of the effect of older age on increased ECT response was explained by the mediators. Treatment planning could be improved by preferentially offering ECT to older adults, especially if presenting with psychotic features, greater severity of psychomotor disturbance, and earlier in the episode.
This was a happy and productive time. Increase in writing and work productivity. Explored theories for my illness, and did lots of music, reading, and socialising, with generally elevated mood. Diagnosis was revised again to bipolar disorder, well controlled on lithium. Further ECT continued as an out-patient; unilateral treatment has less affect on memory.
Working as a consultant psychiatrist and started doing GMC. I Depressed again and tried various antidepressants, hating being off work. Admitted to the Scottish Borders Hospital, where I had been a consultant, and had ECT; I also started olanzapine and put on a lot of weight. A change in psychiatrist and also in diagnosis was difficult.
Returned to Edinburgh five months pregnant, admitted immediately to local psychiatric hospital with psychotic depression. Treated with medication (antidepressants and antipsychotics) and ECT for the first. Poor with medication and relapse.
Poor memory for this time due to repeated admissions, ill-health, and ECT. I was acutely aware and frightened of detention under the Mental Health Act, and of compulsory treatment. Susceptibility to mental illness in families, and how friends and families attempted to explain things. Discussion of my feelings about my psychiatrists and hope that they could help me – also that it was difficult for them as they had never known me well.
Catatonia is a severe neuropsychiatric condition characterized by a state of immobility, stupor, and unresponsiveness to the environment. Signs and symptoms can be thought of in terms of motor signs, affective features, and cognitive-behavioral features. Common symptoms of catatonia can include stupor, rigidity, posturing, mutism, or prolonged excitement and agitation. Benzodiazepines and electroconvulsive therapy are the most commonlly used treatments for catatonia. Both treatments have shown similar efficacy.
Why is it so difficult for older women in our society to feel that they are seen and heard? What matters in our society is not the quality of a woman’s mind, but her appearance of aging. Yet older women are still trying to find meaning in life, despite the impact on their mental and physical health of the menopause, children leaving home, retirement from work, problems in relationships, caring for others and coping with chronic ill health. Women carry a heavy burden of intergenerational caring – for partners, parents, children and grandchildren. As they age, women experience sequential losses in life, of roles that have been important to us. Suicide rates are rising in older women for reasons unknown, and depression can be more severe. Electroconvulsive therapy (ECT) can be life-saving. Alzheimer’s disease is twice as common in women, but we do not know why. Given the massive impact of dementia on women, research is still inadequately funded. Together with younger women we must consider what a feminist old age might look like and, as we age, work at staying engaged with the world. There are things older women can both share with, and learn from, younger women.
Energy intersects with the environment at every stage of its life cycle. The energy supply chain can have adverse effects on nature and public health, including GHG emissions, air, land and water pollution as well the generation of harmful waste, among others. In order to reduce our dependence on high-carbon energy, more needs to be done to increase renewable energy generation and improve energy efficiency. As energy is involved in trade and investment projects, it is covered by the trade and investment branches of international economic law and regulated in these fields mainly by the rules of the World Trade Organization (WTO), the Energy Charter Treaty (ECT), regional trade agreements (RTAs) and international investment agreements (IIAs). This book aims to contribute to the existing scholarship by providing a comprehensive analysis of the energy–environment nexus under trade law and investment law, showing, where relevant, their similarities, differences or even (potential) conflicts at the energy–environment interface. It examines the legal foundations of the energy–environment nexus and associated issues regarding trade control, subsidies, technical standards, investment protection and technology policies.
This chapter examines investment-related aspects of the energy–environment nexus. State actions against fossil fuel investments often have an environmental cause, raising the issue of policy space under the investment regime. The doctrine of ‘police powers’ provides grounds for qualifying some pro-environmental interventions as non-compensable non-expropriatory measures. In addition to seeking policy flexibilities, many States wish energy investors to voluntarily bear social responsibility on the environmental front. As a result, a number of IIAs provide for responsible business conduct, bringing some changes to the ‘investor vs. State’ asymmetry in the investment system. A surge in renewable energy ISDS cases in the last ten years is another noticeable trend. High upfront costs of renewable energy projects recoupable in a long run necessitate FIT or other long-term benefits to investors. But when the government suddenly cancels or cuts promised incentives, this frustrates investors’ legitimate expectations under IIAs but may also be welcomed under trade law as a way of getting rid of distortive subsidies. Thus, some discrepancy or tension between the trade and investment regimes can arise.
