The blood-brain barrier (BBB) plays important roles in both the physiological and pharmacological state of the brain. Transiently enhancing the permeability of the BBB may allow use of more types of medications for neuropsychiatric diseases. Several studies have demonstrated that seizures cause a transient decrease in BBB integrity. We studied the timing of BBB changes following seizures and the role of astrocytes in this process. Rats received 10 applications of electroconvulsive stimulation (ECS). They were then infused with sodium fluorescein, a fluorescent substance that rarely passes the BBB, via the inferior vena cava...

BACKGROUND: The mechanism of drug resistance in epilepsy remains unknown. Picolinic acid (PIC) is an endogenous metabolite of the kynurenine pathway and a chelating agent added to dietary supplements. Both inhibitory and excitatory properties of PIC were reported. The aim of this study was to determine the influence of exogenously applied PIC upon the electroconvulsive threshold and the activity of chemical convulsants in eight models of epilepsy in mice. METHODS: All experiments were performed on adult male Swiss albino mice...

OBJECTIVE: Interleukin-6 (IL-6) has been reported to be elevated in major depressive disorder (MDD) but decreased by antidepressive medication. IL-6 levels are markedly elevated both after epileptic seizures and single electroconvulsive therapy (ECT) session, but long-term changes in IL-6 levels after ECT have not been studied. The correlation between immediate and long-term changes in proinflammatory cytokines and outcome after ECT was investigated. METHOD: Thirty patients suffering from MDD participated in the study...

BACKGROUND: Deep brain stimulation (DBS) has been shown to be effective for parkinsonian symptoms poorly responsive to medications. DBS is typically well-tolerated, as are the maintenance battery changes. Here we describe an adverse event during a battery replacement procedure that caused rapid onset of severe depression. CASE PRESENTATION: The patient is a 58-year-old woman who was in a serious motor vehicle accident and sustained a concussion with loss of consciousness...

The authors report a case of treatment-resistant schizophrenia in a 22-year-old woman, who, despite multiple trials of antipsychotics, did not respond to treatment. Clozapine treatment was initiated, but the patient's symptoms did not remit until after she had a clozapine-induced seizure. The authors discuss the importance in considering that electroconvulsive therapy may be effective in reducing positive and negative symptoms in patients suffering from treatment-resistant schizophrenia.

During a course of electroconvulsive therapy (ECT), the level of currency necessary to induce an epileptic seizure in a patient may either remain relatively stable or-more often-may require repeated upward adjustment over time due to a constantly increasing seizure threshold. We aimed to determine whether a common polymorphism of the brain-derived neurotrophic factor (BDNF), which constitutes an important and ubiquitously expressed neurotrophine in the brain, affects the stimulation threshold of ECTs required to induce an epileptic seizure over time...

BACKGROUND: Brief-pulse electroconvulsive therapy (ECT) is the most acutely effective treatment for severe depression though concerns persist about cognitive side-effects. While bitemporal electrode placement is the most commonly used form worldwide, right unilateral ECT causes less cognitive side-effects though historically it has been deemed less effective. Several randomized trials have now compared high-dose (>5× seizure threshold) unilateral ECT with moderate-dose (1.0-2.5× seizure threshold) bitemporal ECT to investigate if it is as effective as bitemporal ECT but still has less cognitive side-effects...

INTRODUCTION: Simultaneous bilateral femoral neck fracture is an uncommon condition. There are very few cases reported in the literature and most of these cases have underlying bone pathologies such as renal osteodystrophy and osteomalacia. In some cases bilateral femoral neck fractures occur due to generalized seizures or high-energy trauma. PRESENTATION OF CASE: In this case report "atraumatic bilateral femoral neck fracture in a 26year old woman in postpartum period with hypophosphatemic rickets disease" is presented...

BACKGROUND: Electroconvulsive therapy (ECT) is an effective treatment for major affective disorders. The combined use of ECT and anticonvulsant mood stabilizers is a common clinical scenario. There is dearth of systematic studies on the use of this combination with regard to clinical or cognitive outcomes. OBJECTIVE/HYPOTHESIS: We aimed to compare clinical improvement and cognitive adverse effects between patients who received only ECT versus those who received ECT and anticonvulsants...

The microscopic nematode Caenorhabditis elegans has emerged as a valuable model for understanding the molecular and cellular basis of neurological disorders. The worm offers important physiological similarities to mammalian models such as conserved neuron morphology, ion channels, and neurotransmitters. While a wide-array of behavioral assays are available in C. elegans, an assay for electroshock/electroconvulsion remains absent. Here, we have developed a quantitative behavioral method to assess the locomotor response following electric shock in C...

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...

Among non-pharmacological treatments, the ketogenic diet (KD) has the strongest demonstrated evidence of clinical success in drug resistant epilepsy. In an attempt to model the anticonvulsant effects of the KD pre-clinically, the present study assessed the effects of the KD against electroshock-induced convulsions in mice. After confirming that exposure to the KD for 2 weeks resulted in stable ketosis and hypoglycemia, mice were exposed to electroshocks of various intensities to establish general seizure susceptibility...

Posterior shoulder fracture-dislocation is a rare injury accounting for approximately 0.9 % of shoulder fracture-dislocations. Impression fractures of the articular surface of the humeral head, followed by humeral neck fractures and fractures of the lesser and grater tuberosity, are the more common associated fractures. Multiple mechanisms have been implicated in the etiology of this traumatic entity most commonly resulting from forced muscle contraction as in epileptic seizures, electric shock or electroconvulsive therapy, major trauma such as motor vehicle accidents or other injuries involving axial loading of the arm, in an adducted, flexed and internally rotated position...

Electroconvulsive therapy (ECT) is the most effective treatment for patients suffering from severe or treatment-resistant major depressive disorder (MDD). Unfortunately its underlying neurobiological mechanisms are still unclear. One line of evidence indicates that the seizures produced by ECT induce or stimulate neuroplasticity effects. Although these seizures also affect the cortex, the effect of ECT on cortical thickness is not investigated until now. We acquired structural magnetic resonance imaging data in 19 treatment-resistant MDD patients before and after a bilateral ECT course, and 16 healthy controls at 2 time points, and compared changes in cortical thickness between the groups...

OBJECTIVE: The study aimed to identify the predictors for readmission after a successful electroconvulsive therapy (ECT) course. METHODS: Medical charts of patients who received ECT for major depressive episodes were reviewed. Patients' demographic characteristics and treatment parameters, such as ECT charge, seizure duration, the number of ECT sessions and pharmacotherapy, were extracted. We compared differences between those who were readmitted after successful ECT within 6 and 12 months, versus those not readmitted...

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...

Fady Rachid
OBJECTIVE: Nicotine dependence accounts for significant mortality, morbidity, and socio-economic burdens. It remains a significant public health concern since it is among the leading causes of mortality worldwide and of preventable deaths in developed countries. Despite the availability of approved medications to treat nicotine dependence, along with cognitive behavioral therapy, only 6% of the total number of smokers who report wanting to quit each year are successful in doing so for more than a month mostly with poor abstinence rates...
