A Interferência Temporal da Graça de Lily (SLEEP-TIES)

28 de outubro de 2026 atualizado por: University of Wisconsin, Madison

Usando Interferência Temporal para Melhorar Não Invasivamente a Homeostase do Sono em Pacientes com Epilepsia

This study is to evaluate the effectiveness of targeted Transcranial Electrical Stimulation with Temporal Interference (TES-TI) interventions to boost Non-Rapid Eye Movement (NREM) sleep, decrease seizures and promote emotional health in patients with epilepsy. Up to 24 participants (8 control participants for technical optimization prior to recruitment and 16 patients with epilepsy) will be enrolled and can expect to be on study for up to 24 months.

Descrição detalhada

This is a Phase I randomized, single-blind, cross-over feasibility study comprised of 16 participants. Each participant will undergo structural and functional MRI then complete four nights of TES-TI stimulation and four nights of sham stimulation in counterbalanced order, separated by ≥1 day between visits.

Conditions on each visit are randomized and counterbalanced. During each visit, participants will complete both the REST-Q and SSS questionnaires. Full HD-EEG will be applied as well as 4-16 stimulation electrodes. Participants will then undergo an emotion regulation task (face task) wherein they are presented with positive, negative, or neutral emotional stimuli.

This is followed by a resting HD-EEG recording, then overnight stimulation. Either sham or non-sham (8 patients in each group) stimuli will be applied at times during the sleep period. Upon waking, the same questionnaires and emotion regulation tasks will be completed.

Objectives:

  • Assess the efficacy of TES-TI to boost sleep NREM slow-wave activity and spindles in patients with epilepsy overnight
  • Assess the efficacy of TES-TI to improve sleep quality and mood (REST-Q) and sleepiness (sleepiness scale) after treatment (4 nights) vs. before
  • Assess the efficacy of TES-TI to improve emotion responses (face task) and vigilance (psychomotor vigilance task; PVT) after treatment (4 nights) vs. before
  • Assess the efficacy of TES-TI to improve restorative quality of sleep (REST-Q questionnaire) after treatment (4 nights) vs. before
  • Assess the efficacy of TES-TI to reduce seizure frequency (self-reported) after treatment (4 nights) vs. before

Medidas de resultados primários

Medida de resultado
Descrição da medida
Prazo
NREM Sleep Slow-Wave Activity Measured by High-Density EEG (delta power)
Prazo: measured during 8 overnight visits, data collected up to 24 months on study

To assess the effect of TES-TI on NREM sleep slow-wave activity during treatment (4 nights) vs. sham (4 nights), slow-wave activity will be measured by high-density EEG.

measured during 8 overnight visits, data collected up to 24 months on study
Number of Seizures per week
Prazo: data collected at 4 time points up to 24 months on study, 1 month and 3 month follow up after completion of 4 nights treatment and 1 month and 3 month follow up after completion 4 nights sham condition

To assess the effect of TES-TI on incidence of seizures after treatment (4 nights) vs. sham (4 nights), participants will maintain a seizure diary. The self-reported number of seizures seizures per week for the first week and the first four-weeks post-intervention.

data collected at 4 time points up to 24 months on study, 1 month and 3 month follow up after completion of 4 nights treatment and 1 month and 3 month follow up after completion 4 nights sham condition
Psychomotor Vigilance Task (PVT)
Prazo: measured during 8 overnight visits, data collected up to 24 months on study

The vigilance task will be used to assess the effect of TES-TI on performance after treatment (4 nights) vs. sham (4 nights). This is a computerized reaction time task where a participant is presented with a fixation point on a computer screen. At random, the fixation point will change appearance at which point the participant is to click a provided button as quickly as possible. The time it took to respond is recorded automatically by the computer program and will be reported as the result.

measured during 8 overnight visits, data collected up to 24 months on study
Restorative Sleep Questionnaire (REST-Q)
Prazo: measured during 8 overnight visits, data collected up to 24 months on study

The REST-Q measure will be used to assess the effect of TES-TI on sleep quality and mood after treatment (4 nights) vs. sham (4 nights). It is a 9-item questionnaire assessing aspects of restorative sleep. Each item is scored on a 5-point Likert scale (1-light; 5-deep). Final scores are transformed to a scale of 0-100 here higher scores indicate more restorative sleep.

measured during 8 overnight visits, data collected up to 24 months on study
Stanford Sleepiness Scale (SSS)
Prazo: measured during 8 overnight visits, data collected up to 24 months on study

The Stanford Sleepiness Scale will be used to assess sleepiness after treatment (4 nights) vs. sham (4 nights). SSS is a measure of subjective alertness on a 7-point scale (total range of scores from 1-7). A lower score on the scale indicates higher alertness.

measured during 8 overnight visits, data collected up to 24 months on study
Emotional Processing Task (Face Task): Percent Correct
Prazo: measured during 8 overnight visits, data collected up to 24 months on study

The Face Task will be used to assess the effect of TES-TI on emotion response after treatment (4 nights) vs. sham (4 nights). This task involves viewing a series of emotionally charged images (60 positive, 60 negative, 60 neutral).

Emotional Processing Task (Face Task): Percent Change in Reaction Time
Prazo: measured during 8 overnight visits, data collected up to 24 months on study

The Face Task will be used to assess the effect of TES-TI on emotion response after treatment (4 nights) vs. sham (4 nights). This task involves viewing a series of emotionally charged images (60 positive, 60 negative, 60 neutral).
