Summary
This study compares temporal interference stimulation (TIS) and transcranial alternating current stimulation (tACS) for treating post-stroke cognitive dysfunction. Researchers will assess cognitive improvements using various tests over two weeks to determine the most effective neuromodulation technique.
Area of Science:
- Neuroscience
- Neuromodulation
- Clinical Trials
Background:
- Electrical neuromodulation therapies like tACS and TIS show promise for cognitive impairments.
- Temporal interference stimulation (TIS) is a novel technique offering deep, non-invasive brain stimulation.
- The comparative efficacy of TIS and tACS for post-stroke cognitive dysfunction (PSCI) remains unclear.
Purpose of the Study:
- To compare the neuromodulation models and clinical performance of TIS and tACS in patients with mild PSCI.
- To evaluate the effectiveness of TIS and tACS in improving cognitive function after stroke.
Main Methods:
- A prospective, single-blind, randomized controlled trial involving 36 participants with mild PSCI.
- Participants were randomly assigned to either TIS (2005 Hz and 2010 Hz, targeting the hippocampus) or tACS (5 Hz, targeting the dorsolateral prefrontal cortex).
- Intervention lasted two weeks, with daily 25-minute sessions, five times per week. Cognitive assessments (MoCA, N-back, DST, STT) and fNIRS were conducted pre- and post-intervention.
Main Results:
- Primary outcome: Montreal Cognitive Assessment (MoCA) scores.
- Secondary outcomes: Performance on N-back task, digital span test (DST), shape trails test (STT), and functional near-infrared spectroscopy (fNIRS) data.
- Data collected at baseline (T1) and post-intervention (T2).
Conclusions:
- This trial will provide critical data on the comparative effectiveness of TIS and tACS for PSCI.
- Findings will help elucidate the distinct neuromodulation mechanisms and clinical outcomes of these two techniques.
- Results may guide the selection of optimal neuromodulation strategies for stroke recovery.
