Maintenance electroconvulsive therapy (ECT) is sometimes prescribed for refractory psychiatric conditions. We describe five patients who received maintenance ECT and developed florid temporal epileptiform abnormalities on electroencephalography (EEG) despite no history of epilepsy and normal neuroimaging. All patients had received regular ECT for at least 8 months. Three patients had clinical events consistent with epileptic seizures, and video-EEG monitoring captured electrographic seizures in two patients...

BACKGROUND/AIM: In this prospective randomized cross-over study we compare the effects of sevoflurane versus propofol for electroconvulsive therapy (ECT) anesthesia. MATERIALS AND METHODS: Twenty four patients (ASA I-III, 18-65 years old) receiving ECT three times per week were included. Anesthesia was induced with either propofol (0.75 mg/kg iv) or 5% sevoflurane in 100% oxygen. Consecutive ECT sessions followed a 2 × 2 crossover design and a 2-day washout period until the 10th ECT...

BACKGROUND: This study aimed to investigate the modified electroconvulsive therapy (MECT) on the electroencephalogram (EEG) of schizophrenia patients. A total of 26 schizophrenia patients who received MECT were recruited. EEG recording was initiated at 30 min before 1st and 6th MECT and terminated on the 2nd day. Images without artifacts were selected for the analysis of δ, θ, α1, α2 and β bands. The wave energy at each frequency, index of waves at different bands from the same lead, index of waves at the same band from different leads, time of epileptic discharge, time of resting state, and time to the stable EEG were determined and compared...

In order to optimise outcome to Electro Convulsive therapy (ECT), there has been a trend to utilise remifentanil as an adjunct to standard intravenous induction agents. This has allowed a reduction in the dose of anaesthetic agent, and usually an improved response to stimulation. However there have been no previous studies to ascertain whether this improvement is simply as a result of the reduced dose of anaesthetic agent or whether remifentanil itself might possess epileptogenic properties. This retrospective case-controlled study examined ECT outcomes, determined by EEG quality analysis, in patients who received ECT with or without remifentanil, where there was no dose reduction in the anaesthetic agent...

OBJECTIVE: The aim of the study was to survey the media landscape to determine whether visual depictions of electroconvulsive therapy (ECT) are becoming more or less medically accurate in the new millennium. METHOD: English-language film and television shows depicting ECT were analyzed for patient demographics, administrator roles, indication, consent, anesthesia, paralytics, bite block, lead placement, electroencephalogram, and outcome. RESULTS: Thirty-nine ECT scenes were viewed, and just 3 included all 5 essential tools of modern ECT: anesthesia, paralytic, electrodes, electroencephalogram, and a bite block...

In electroconvulsive therapy (ECT), remifentanil is often used concurrently with anesthetics. The objective of this study was to provide an up-to-date and comprehensive review on how the addition of remifentanil to anesthetics affects seizure duration and circulatory dynamics in mECT. We performed a meta-analysis of RCTs that investigated seizure duration and circulatory dynamics in patients treated with ECT using anesthetics alone (non-remifentanil group) and with anesthetics plus remifentanil (remifentanil group)...

Electroconvulsive therapy (ECT), the most efficacious antidepressant therapy for treatment-resistant depression, has been reported to alter functional brain network architecture by down-regulating connectivity in frontotemporal circuitry. Magnetic seizure therapy (MST), which induces therapeutic seizures with high dose repetitive transcranial magnetic stimulation, has been introduced to improve the seizure therapy risk/benefit ratio. Unfortunately, there is limited understanding of seizure therapy's underlying mechanisms of action...

Anti-N-methyl-d-aspartate receptor (NMDAR) encephalitis is a disease occurring when antibodies produced by the body's own immune system attack NMDA-type glutamate receptors in the brain. Most anti-NMDAR encephalitis cases are associated with paraneoplastic syndrome. We analyze the case of a 15-year-old girl who was hospitalized in a child psychiatry clinic in Riga, Latvia, with de novo acute polymorphic psychotic disorder gradually progressing to a catatonic state. The patient received antipsychotic and electroconvulsive therapy with no beneficial effect...

BACKGROUND: Nonconvulsive status epilepticus (NCSE) defines a prolonged electrographic seizure activity resulting in nonconvulsive symptoms. Semiology is a crucial element in diagnosis, etiological evaluation, and treatment plan of NCSE. It includes mostly generalized myoclonic status (GMS), focal simple motor status (FSMS), and dyscognitive status (DS). REVIEW SUMMARY: This review aims to guide clinicians in diagnosis, etiological evaluation, and treatment of patients with NCSE based on semiological presentation...

Autism spectrum disorders (ASD) are heterogeneous neurodevelopmental disorders that are reportedly characterized by aberrant neural networks. Recently developed multiscale entropy analysis (MSE) can characterize the complexity inherent in electroencephalography (EEG) dynamics over multiple temporal scales in the dynamics of neural networks. We encountered an 18-year-old man with ASD whose refractory catatonic obsessive-compulsive symptoms were improved dramatically after electroconvulsive therapy (ECT). In this clinical case study, we strove to clarify the neurophysiological mechanism of ECT in ASD by assessing EEG complexity using MSE...

OBJECTIVES: We evaluated the effects of a subanesthetic dose of ketamine, which was administered as an adjunct to sevoflurane, on duration of seizure activity, hemodynamic profile, and recovery times during electroconvulsive therapy in patients with major depression. METHODS: Patients were randomly allocated to a group receiving either sevoflurane-ketamine (group SK) or sevoflurane-saline (group SS). Sevoflurane was initiated in both groups at 8% for anesthesia induction until loss of consciousness was achieved, at which point it was discontinued...

UNLABELLED: The optimum induction agent for anesthesia for electroconvulsive therapy (ECT) has been long debated. Ideal agent should be short acting with minimal suppression of seizure potentials. Recent studies have suggested longer seizure duration with etomidate in comparison to propofol, thiopental, and methohexital. The aim of the present meta-analysis was to pool data available from studies comparing systematically the efficacy of etomidate against other induction agents in terms of seizure duration (both electroencephalography (EEG) and motor)...

INTRODUCTION: The aim of the present study was to evaluate the utility of different tests performed in the absence or presence of factors promoting seizures in order to evaluate the pro-convulsant effects of drugs. We studied the effects of theophylline in the rat since this is a well-known pro-convulsant substance in humans. METHODS: The occurrence of spontaneous convulsions following administration of theophylline was evaluated by observation in the Irwin Test and by measuring brain activity using video-EEG recording in conscious telemetered animals...

INTRODUCTION: Neuroleptic malignant syndrome is rare, but potentially fatal idiosyncratic reaction to antipsychotic medications. It is sometimes difficult to diagnose some clinical cases as neuroleptic malignant syndrome and differentiate it from the acute viral encephalitis. CASE REPORT: We reported a patient diagnosed with acute psychotic reaction which appeared for the first time. The treatment started with typical antipsychotic, which led to febrility. The clinical presentation of the patient was characterised by the signs and symptoms that might have indicated the neuroleptic malignant syndrome as well as central nervous system viral disease...
