چکیده
هدف پژوهش حاضر مقایسه اثربخشی روش تحریک الکتریکی مغز با جریان مستقیم و پروتکل توانبخشی شناختی کوتاه­مدت بر علائم توهم و هذیان در سالمندان مبتلا به آلزایمر خفیف بود. روش پژوهش، آزمایشی گسترش یافته با دو گروه آزمایش و یک گروه کنترل بود که با استفاده از روش پیش­آزمون و پس­آزمون انجام شد. جامعه آماری کلیه سالمندان بالای 65 سال مبتلا به آلزایمر خفیف را شامل می­شد که در سال 1401 به پزشک مغز و اعصاب مراجعه کرده­ بودند که از بین این افراد، 60 نفر به صورت نمونه­گیری در دسترس انتخاب و سپس به صورت تصادفی در دو گروه آزمایش و یک گروه کنترل (هر گروه 20 نفر) گمارده شدند. سپس متغیرهای مستقل مداخله تحریک الکتریکی مغز با جریان مستقیم (tDCS) به مدت 10 جلسه 20 دقیقه­ای به صورت هفته­ای یک بار روی یک گروه آزمایش و برنامه توانبخشی شناختی کوتاه مدت به تعداد 9 جلسه­ (هر جلسه 90 دقیقه) که به روش اسنادی و بر اساس رویکرد جایگزینی کارکرد سالم لوریا (1963) طراحی و پس از تائید روایی محتوا توسط متخصصین، به صورت هفته­ای یک بار روی گروه آزمایش دوم اعمال شد و بر روی گروه سوم هیچ مداخله­ای انجام نشد. بعد از خاتمه مداخله، پس­آزمون با فاصله یک هفته بر روی گروه­های آزمایش و گروه کنترل اجرا شد. بعد از یک ماه مجدد گروه­های مورد مطالعه مورد پیگیری قرار گرفتند. جهت جمع­آوری اطلاعات از پرسشنامه نوروپسیکولوژیک (NPI) استفاده شد. نتایج نشان داد که هر دو روش موجب بهبود علائم توهم در سالمندان مبتلا به آلزایمر خفیف می­شود و تفاوت معناداری بین اثربخشی این دو روش وجود ندارد. در حالی که بر روی متغیر هذیان تأثیر معناداری نداشتند. از این رو می­توان نتیجه گرفت که از هر دو روش می­توان در جهت بهبود توهم در سالمندان مبتلا به آلزایمر خفیف بهره جست.

چکیده English

The purpose of this study was to compare the effectiveness of transcranial direct current stimulation (tDCS) and short-term cognitive rehabilitation protocol on Symptoms of hallucinations and delusions in the elderly with mild Alzheimer's disease. The research method was an extended experiment with two experimental groups and one control group, which was conducted using the pre-test and post-test method. The statistical population included all elderly people over 65 years of age with mild Alzheimer's who had referred to a neurologist in 1401, and among these people, 60 people were selected by available sampling and then randomly. They were assigned in two experimental groups and one control group (20 people in each group). Then, the independent variables of transcranial direct current stimulation (tDCS) for 10 sessions of 20 minutes once a week on an experimental group and a short-term cognitive rehabilitation program for 9 sessions (90 minutes each session) It was designed according to the documentary method and based on Luria's (1963) healthy function replacement approach, and after confirming the validity of the content by experts, it was applied to the second experimental group once a week, and no intervention was performed on the third group. After the end of the intervention, the post-test was conducted with an interval of one week on the experimental and control groups. After one month, the studied groups were followed up again. Neuropsychological Questionnaire (NPI) was used to collect data. The results showed that both methods improve hallucination symptoms in the elderly with mild Alzheimer's and there is no significant difference between the effectiveness of these two methods. while they had no significant effect on the delusion variable. Therefore, it can be concluded that both methods can be used to improve hallucinations in the elderly with mild Alzheimer's disease.
