Trial Summary
What is the purpose of this trial?
Background: Electroconvulsive therapy (ECT) is used to treat people with severe depression. During ECT, the brain is given electric pulses that cause a seizure. Although it is effective, it can cause side effects, including memory loss. Researchers want to study a new way to give ECT called iLAST. Objective: To see if iLAST is safe and feasible in treating depression. Eligibility: People ages 22 70 years old who have major depressive disorder and are eligible for ECT Design: Participants will be screened under protocol 01-M-0254. This includes: Medical and psychiatric history and exam Blood and urine tests Participants will be inpatients at the Clinical Center. They study has 3 phases and will last up to 20 weeks. Phase I will last 1 week. It includes: MRI: Participants will lie in a scanner that takes pictures of the body MEG: A cone over the participant s head will record brain activity. TMS: A wire coil placed on the participant s scalp will produce an electrical current to affect brain activity. SEP: An electrode on the participant s wrist will give a small electrical shock to test nerve function. Phase II will last 2 and a half weeks. It includes: Seven sessions of iLAST under general anesthesia. Participants may also get standard ECT. EEG: A small electrode placed on the participant s scalp will record brain waves. Interviews about mood, symptoms, and side effects. Participants facial expressions may be video recorded. TMS Phase III will last at least 1 week. It will include: MRI EEG TMS MEG Standard ECT if needed. Participants will have sessions every other day, 3 times a week.
Do I have to stop taking my current medications for the trial?
You must be on a stable dose of all psychotropic medications for 4 weeks before the trial and cannot change them during the experimental phase unless advised by the Investigator.
What data supports the idea that iLAST for Depression is an effective treatment?
The available research does not provide any data on iLAST for Depression. Instead, it focuses on treatments for epilepsy, discussing the effectiveness of different drug therapies for managing seizures. Therefore, there is no information here to support the effectiveness of iLAST for Depression.12345

Findings from Research
In a study of 44 patients on monotherapy with a drug within the therapeutic range, 75% experienced a reduction in seizure frequency, highlighting the efficacy of this treatment approach.
The treatment showed a 90% improvement in Primary Generalized seizures, suggesting it is particularly effective for this type, and supports the recommendation of monotherapy as a first-line treatment due to its manageable nature and lower toxicity.

Transitional polytherapy, which involves gradually introducing a new antiepileptic drug (AED) while adjusting the dose of the existing medication, is the preferred method for switching between monotherapies in epilepsy treatment to avoid adverse effects and seizure exacerbation.
The choice between a fixed-dose or flexible titration strategy during this transition depends on the patient's current condition: a fixed strategy is best when there are no adverse effects, while a flexible approach is necessary when patients are experiencing side effects from their current medication.

The development of new anti-epileptic drugs (AEDs) allows for more personalized treatment plans based on individual patient needs and responses, highlighting the importance of tailoring therapy to each person's unique condition.
Successful AEDs should possess optimal characteristics such as efficacy, tolerability, and cost-effectiveness, which are essential for achieving better seizure control and addressing the broader goals of epilepsy management.

The novel 2-step intensity-modulated arc therapy (IMAT) techniques showed equal or improved plan quality compared to traditional methods like direct machine parameter optimization (DMPO) and were superior to commercial volumetric arc therapy (SMARTARC) techniques in a study involving various complex target volumes.
The 2-step IMAT techniques demonstrated significant improvements in plan quality, with reductions in composite objective value (COV) by factors of 1.4 to 2.4 for different cases, indicating their potential for effective and efficient radiation therapy adaptation.

The study developed a real-time electromagnetic-guided dynamic multileaf collimator (DMLC) tracking system for intensity-modulated arc therapy (IMAT), which significantly improved dose delivery to moving targets in lung and prostate cancer cases, with only 1.6% and 1.2% of dose points failing the accuracy test compared to 34% and 14% without tracking.
The DMLC tracking system maintained the same treatment delivery time as traditional methods, demonstrating that it enhances treatment precision without sacrificing efficiency.

A 'start low, go slow' approach to titrating antiseizure medications (ASMs) is recommended to minimize the risk of severe side effects and improve patient tolerability, especially for common central nervous system-related issues like drowsiness and dizziness.
When switching or adding ASMs, careful management and communication with patients are crucial to ensure effective disease control while minimizing the overall drug load, which can help reduce toxicity and improve treatment adherence.

In a study of 25 depressed patients undergoing unilateral ECT, those receiving moderately suprathreshold (2.5T) treatments exhibited significantly stronger seizure activity, indicated by greater ictal spectral amplitude and coherence, which may enhance therapeutic outcomes.
A multivariate ictal EEG model was able to accurately differentiate between treatment intensity groups with 90% accuracy, suggesting it could be a valuable tool for optimizing ECT stimulus intensity in clinical settings.
