BACKGROUND: Studies have examined the effects of electroconvulsive therapy (ECT) on human cardiac electrophysiology. However, no study has so far examined whether these effects vary with the magnitude of the electrical dose used to elicit the seizure. Because the benefits and adverse effects of the ECT seizure are dose-dependent, we examined the effects of different electrical doses of electroconvulsive shocks (ECS) on cardiac electrophysiology in an animal model with a view to determine whether cardiac electrophysiology could be a useful proxy to evaluate the quality of the ECT seizure...

Inducing adequate therapeutic seizures during electroconvulsive therapy (ECT) is sometimes difficult due to a high seizure threshold, even at the maximum stimulus charge. Previous studies have demonstrated that seizure threshold is lower in patients treated with right unilateral ultrabrief pulse (RUL-UBP) ECT than in those treated with bilateral or brief pulse (BL-BP) ECT. Therefore, switching to RUL-UBP ECT may be beneficial for patients in whom seizure induction is difficult with conventional ECT. In the present report, we discuss the case of a patient suffering from catatonic schizophrenia in whom BL-BP ECT failed to induce seizures at the maximum charge...

OBJECTIVE: Electroconvulsive therapy (ECT) is the most robust acute treatment for severe major depressive disorder, yet clinical response is variable. Inflammation is associated with depression, especially in women, and levels of C-reactive protein (CRP) and interleukin (IL)-6 predict response to antidepressant medications. This study evaluated whether markers of inflammation predicted response to electroconvulsive therapy (ECT) in patients with treatment-resistant depression and to what extent this association differed between men and women...

Electroconvulsive therapy (ECT) is the treatment method widely used in psychiatric disorders such as depression, bipolar disorder, schizophrenia and schizoaffective disorder. The advantage of ECT is therapeutic response that occurs significantly earlier than during pharmacotherapy. Initially ECTwas used without anesthesia. Then, in the 1950s procedures with general anesthesia were introduced to reduce the complications that may occur during a seizure caused by ECT, such as broken bones, teeth, tendon rupture, muscle damage...

BACKGROUND: Electroconvulsive therapy (ECT) continues to be the most efficacious treatment for severe depression and other life-threatening acute psychiatric conditions. Treatment efficacy is dependent upon the induced seizure quality, which may be influenced by a range of treatment related factors. Recently, the time interval from anesthesia to the electrical stimulation (ASTI) has been suggested to be an important determinant of seizure quality. METHODS: We measured ASTI in 73 ECT sessions given to 22 individual patients, and analyzed its influence on five seizure quality parameters (EEG seizure time, power, coherence, postictal suppression, and peak heart rate)...

OBJECTIVE: The feasibility and effectiveness of concomitant use of transcranial direct current stimulation (tDCS) with electroconvulsive therapy (ECT) has not been investigated. The study principally aimed at determining whether tDCS when combined with ECT improved the speed of antidepressant response. Secondarily, the ease of generation of seizures during electroconvulsive therapy and cognitive outcomes were investigated. METHODS: Consecutive patients referred for ECT to treat major depression were randomized to tDCS with dorsolateral prefrontal electrode placements (n = 8) or sham (n = 8) used daily and just before thrice weekly, 6 times threshold, right unilateral ultrabrief (0...

BACKGROUND AND AIM OF THE WORK: electroconvulsive therapy is a psychiatric procedure requiring general anesthesia. The choice of the hypnotic agent is important because the success of the intervention is associated to the occurrence and duration of motor convulsion. However, all available anesthetic agents have anti-convulsant activity. We compared the effect of thiopental and propofol on seizures. METHODS: We designed a retrospective study at Mood Disorders Unit of a teaching Hospital...

BACKGROUND: Recent evidence reveals therapeutic potential for cannabinoids to reduce seizure frequency, severity and duration. Animal models are useful tools to determine the potential antiseizure or antiepileptic effects of cannabinoids. The objective of this study was evaluation of the effect of arvanil, olvanil, AM 1172 and LY 2183240, the compounds interacted with endocannabinoid and/or endovanilloid systems, on convulsions in the commonly used model of convulsions in mice. METHODS: Arvanil and olvanil were injected intraperitoneally (ip) 30 min and AM 1172 and LY 2183240 were administered ip 60 min before the maximal electroshock seizure threshold (MEST) test...

BACKGROUND: Magnetic seizure therapy (MST) is a novel brain stimulation technique that uses a high-powered transcranial magnetic stimulation device to produce therapeutic seizures. Preliminary MST studies have found antidepressant effects in the absence of cognitive side effects but its efficacy compared to electroconvulsive therapy (ECT) remains unclear. The aim of this study was to investigate the therapeutic efficacy and cognitive profile of MST compared to standard right unilateral ECT treatment...

Cardiac arrhythmia may occur in the course of epilepsy. Simultaneous therapy of the two diseases might be complicated by drug interactions since antiarrhythmic and antiepileptic agents share some molecular targets. The aim of this study was to evaluate the influence of amiodarone, an antiarrhythmic drug working as a multi-channel blocker, on the protective activity of four classical antiepileptic drugs in the maximal electroshock test in mice. Amiodarone at doses up to 75 mg/kg did not affect the electroconvulsive threshold in mice...

OBJECTIVE: Evidence suggests that magnetic seizure therapy (MST) results in fewer side effects than electroconvulsive treatment, both in humans treated with electroconvulsive therapy (ECT) as well as in the animal preclinical model that uses electroconvulsive shock (ECS). Evidence suggests that MST results in fewer cognitive side effects than ECT. Although MST offers enhanced control over seizure induction and spread, little is known about how MST and ECT seizures differ. Seizure characteristics are associated with treatment effect...

Background: Electroconvulsive therapy is a fast-acting and efficient treatment of depression used in the clinic. The underlying mechanism of its therapeutic effect is still unclear. However, recovery of synaptic connections and synaptic remodeling is thought to play a critical role for the clinical efficacy obtained from a rapid antidepressant response. Here, we investigated the relationship between synaptic changes and concomitant nonneuronal changes in microvasculature and mitochondria and its relationship to brain-derived neurotrophic factor level changes after repeated electroconvulsive seizures, an animal model of electroconvulsive therapy...

OBJECTIVE: The appropriate use of analgesic drugs based on their degree of analgesia and adverse effects is important for pain management. Although it has been reported that AM404, a metabolite of acetaminophen, has anticonvulsant effects in several animal seizure models, little is known about the relation between acetaminophen and seizures. We therefore investigated the effects of acetaminophen on seizure susceptibility in several mouse seizure and epilepsy models and compared the effects with those of nonsteroidal anti-inflammatory drugs (NSAIDs)...

OBJECTIVE: To examine the provenance and implications of seizure threshold titration in electroconvulsive therapy. BACKGROUND: Titration of seizure threshold has become a virtual standard for electroconvulsive therapy. It is justified as individualisation and optimisation of the balance between efficacy and unwanted effects. RESULT: Present day threshold estimation is significantly different from the 1960 studies of Cronholm and Ottosson that are its usual justification...

Experimental studies showed that certain angiotensin-converting enzyme inhibitors and angiotensin AT1 receptor antagonists can decrease seizure severity in rodents. Additionally, some of these blockers of the renin-angiotensin system have been documented to enhance the anticonvulsant activity of antiepileptic drugs against maximal electroshock-induced seizures. The aim of the current study was to investigate the effect of aliskiren, a direct renin inhibitor and a novel antihypertensive drug, on the protective action of numerous antiepileptic drugs (carbamazepine, valproate, clonazepam, phenobarbital, oxcarbazepine, lamotrigine, topiramate and pregabalin) in the test of maximal electroshock in mice...

BACKGROUND: Electroconvulsive therapy (ECT) is a rapid acting and effective treatment for both major depressive disorder (MDD) and bipolar disorder (BP). Both propofol and ketamine are commonly used anesthetic agents but recent clinical studies suggest that ketamine has rapid-acting antidepressant properties, itself, at sub-anesthetic doses. METHODS: A total of 77 inpatients (41 MDD and 36 BP) were randomly assigned to receive ECT with propofol (1mg/kg) anesthesia or with ketamine (0...

BACKGROUND: Sotalol as a drug blocking β-receptors and potassium KCNH2 channels may interact with different substances that affect seizures. Herein, we present interactions between sotalol and four conventional antiepileptic drugs: carbamazepine, valproate, phenytoin and phenobarbital. METHODS: Effects of sotalol and antiepileptics alone on seizures were determined in the electroconvulsive threshold test, while interactions between sotalol and antiepileptic drugs were estimated in the maximal electroshock test in mice...

PURPOSE: Current analgesic strategies for propofol injection pain may cause adverse reactions during electroconvulsive therapy (ECT), such as shortening seizure duration. This study investigated whether dexmedetomidine could attenuate propofol injection pain in ECT. METHODS: Participants were randomly allocated to receive 0.2 μg/kg dexmedetomidine (Dex-0.2 group), 0.5 μg/kg dexmedetomidine (Dex-0.5 group) or saline (control group) prior to ECT. The composite pain scale and objective Surgical Pleth Index (SPI) were used to measure the intensity of injection pain, and the percentage of patients with pain score > 2 was the primary outcome...

Electroconvulsive therapy (ECT) is a safe and effective treatment for major depressive disorder, but cerebrovascular and cardiovascular complications, although rare, remain the most concerning. This is particularly notable in those with preexisting cerebrovascular disease, which impacts dynamic cerebral autoregulation. In these patients, the increased blood flow to the seizing portions of the brain induced by ECT potentially can reduce cerebral blood flow to ischemic areas, possibly causing adverse neurological events...

In the central nervous system, CaV 1.2 and CaV 1. 3 constitute the main L-type voltage-gated calcium channels (LTCCs) coupling membrane depolarization to gene transcription. We have previously demonstrated that inducible disruption of Cav1.2 in type-1 astrocyte-like stem cells of the adult dentate gyrus (DG) impairs hippocampal neurogenesis in a cell-autonomous fashion. To address the role of Cav1.3 channels (encoded by the Cacna1d gene), we here generated Tg(GLAST-CreERT2) /Cacna1d(fl/fl) /RCE:loxP mice which facilitate inducible deletion of Cacna1d in tandem with induction of EGFP expression in type-1 cells, allowing tracking of recombined cells and their descendants...
