التجربة السريرية NCT07097051 مصممة لدراسة علاج لـضعف الإدراك الخفيف (MCI). إنها تجربة تدخُّلية من المرحلة الثانية وهي يقبل مشاركين. بدأت في ١٥ ذو القعدة ١٤٤٦ هـ مع خطة لتجنيد ٢٠ مشاركًا. تقودها High Point University، ومن المتوقع اكتمالها بحلول ٢٢ رجب ١٤٤٨ هـ. تم تحديث البيانات الأخيرة من ClinicalTrials.gov في ٦ صفر ١٤٤٧ هـ.
الملخص
Older adults with Mild Cognitive Impairment (MCI) often show less brain activity in a specific range (8-13 Hz, known as alpha power) compared to healthy older adults. Those with lower alpha activity, especially in the front part of the brain, usually have problems with executive functions like planning and multitasking. Our research has shown that older adults with lower alpha power in these areas also struggle more ...عرض المزيد
وصف مفصل
Older adults with Mild Cognitive Impairment (MCI) exhibit reduced brain alpha power (i.e., activity fluctuations in the 8-13 Hz range) compared to healthy older adults, and older adults who exhibit lower alpha activity in the fronto-central areas tend to have impaired executive function. In addition, our group has demonstrated that older adults who exhibit lower fronto-central alpha power during dual-task standing (i...عرض المزيد

تجريبيةreal tACS
The investigators will administer the transcranial alternating current stimulation (tACS) intervention individually tailored to peak alpha power to the participants. This intervention will utilize 8 electrodes; electrode placement and current parameters for each electrode have been optimized using a standard brain to generate an average electric field of 0.25 V/m. To ensure adherence to current safety recommendations...عرض المزيد
التحفيز بالتيار المتردد عبر الجمجمة الحقيقي (tACS)
Those who randomized into real tACS arm will receive ten-session of individually tailored tACS targeting peak alpha power for 20-minutes
مقارن بالدواء الوهميsham tACS
The investigators will administer the sham tACS intervention to the participants. They will use an active sham in which very low-level alternating currents (0.5 mA total) will be transferred between electrodes in close proximity on the scalp throughout the session. Stimulation will start and end with a 60 s ramp up/down to maximize comfort and the entire session will last in 22-minutes.

EEG alpha-band power
Change of EEG oscillations and frequency coupling at 8-13 Hz
Baseline, immediate post-intervention assessments, Follow-up visit #1 (4 weeks later of post-intervention assessment, Follow-up visit #2 (12 weeks later post-intervention assessment).
Change of postural sway speed
his metric assesses the ability to control standing posture
Baseline, immediate post-intervention assessments, Follow-up visit #1 (4 weeks later of post-intervention assessment, Follow-up visit #2 (12 weeks later post-intervention assessment).
النتيجة الثانوية
مقياس النتيجةوصف القياسالإطار الزمني
Change of executive function score
This metric reflects measures of executive function scores based on individual neuropsychological test of Trail-making Test B completion time
Baseline, immediate post-intervention assessments, Follow-up visit #1 (4 weeks later of post-intervention assessment, Follow-up visit #2 (12 weeks later post-intervention assessment).
Change of dual-task gait speed
This metric (m/s) assesses the ability to walk and perform a cognitive task at the same time and predicts cognitive decline and the development of dementia.
Baseline, immediate post-intervention assessments, Follow-up visit #1 (4 weeks later of post-intervention assessment, Follow-up visit #2 (12 weeks later post-intervention assessment).
Timed Up and Go Test completion time
This test assesses time to complete standing from a chair, walking three meters, turning around a cone and returning to a seated position in the chair.
Baseline, immediate post-intervention assessments, Follow-up visit #1 (4 weeks later of post-intervention assessment, Follow-up visit #2 (12 weeks later post-intervention assessment).
Short Physical Performance Battery score
This common test assesses physical functioning. The score is ranging from 0 to 12, with higher scores indicating better physical performance.
Baseline, immediate post-intervention assessments, Follow-up visit #1 (4 weeks later of post-intervention assessment, Follow-up visit #2 (12 weeks later post-intervention assessment).
Montreal Cognitive Assessment (MoCA)
This common test assesses global cognitive function. The Montreal Cognitive Assessment (MoCA) test is scored out of a total of 30 points, with higher scores indicating better cognitive function.
Baseline, immediate post-intervention assessments, Follow-up visit #1 (4 weeks later of post-intervention assessment, Follow-up visit #2 (12 weeks later post-intervention assessment).
Dual-task Standing Postural Sway Path
This metric assesses the ability to stand and perform a cognitive task at the same time and predicts cognitive decline and the development of dementia.
Baseline, immediate post-intervention assessments, Follow-up visit #1 (4 weeks later of post-intervention assessment, Follow-up visit #2 (12 weeks later post-intervention assessment).
Serial subtraction test performance
This metric assesses the number of correct response on serial subtraction test while standing
Baseline, immediate post-intervention assessments, Follow-up visit #1 (4 weeks later of post-intervention assessment, Follow-up visit #2 (12 weeks later post-intervention assessment).
Digit Span total recall
This metric assesses working memory.
