#Internet #addiction #antecendants: #Self-control as a predictor

Abstract
#Internet_addiction is a result of #penetration of internet #technology to the #modern #world and has inundated a substantial proportion of #human #societies, so that many of mental professionals have considered it as a mounting threatening issue of mental health. Many factors are suggested to be of capability of #predicting internet addiction, include #self_efficacy and #self_control, whose roles are evaluated in this study. This survey study was conducted on 395 female and male #university #students of SardarJangal University, Rasht, Iran. #Instruments comprised #Internet #Addiction #Test , and Self-Control Scale (Tangney, 2004), which were administered by all participants. findings of #regression analysis showed that self-control has #significant negative relation with internet addiction (p<.05) and male students gained higher scores in internet addiction than females. Moreover, no significant difference was found among students of different university majors in internet addiction scores. It appears that self-control abilities can reduce the rate of internet addiction in university students. Therefore, future programs and plans of tri-layer #prevention can focus on teaching for self-control among university students as well as school-ageed students and families to deliberately decrease internet addiction in various sectors of society.

♻️#رقصیدن #پیری #بدن و #مغز را کند می نماید

#Dancing or #Fitness #Sport? The Effects of Two #Training Programs on #Hippocampal #Plasticity and #Balance Abilities in #Healthy #Seniors

پژوهشگران نوروساینس دانشگاه ماگدِبورگ 🇩🇪 در پژوهشی که گزارش آن به تازگی منتشر شده است دریافتند که در میان فعالیت های بدنی، رقصیدن بیش از همه در #کندسازی روند پیری در بدن و مغز موثر است.

🔬در این پژوهش که دو برنامه روزانه متفاوت تناسب اندام ارائه شد که هر دو توانستند در مغز و بدن سالمندان تاثیر #ضدپیری را نشان دهند. در گروه رقص 14 نفر و در گروه #تناسب #اندام #ایروبیکس 12 نفر سالمند داوطلب حضور داشتند. برنامه تمرینی دو جلسه 90 دقیقه ای در هفته به مدت 6 ماه ادامه یافت.
📚تحلیل های مغزی بر اساس #MRI صورت گرفت. تغییرات در هر دو گروه در اندازه #هیپوکامپ چپ به شکل معناداری صورت گرفت. اما در بررسی های گسترده تر مشخص شد تنها رقصیدن توانست #شکنج #دندانه دار چپ و راست منجر به افزایش اندازه و حجم شود. این امر منجر به بروز تغییرات در سطح #رفتاری برای کاهش روند پیری می شود. بنابراین تنها رقص می تواند هم تغییرات مغزی و هم تغییرات رفتاری برای کاهش روند پیری ایجاد نماید.

Abstract
#Age-related #degenerations in #brain #structure are associated with balance disturbances and #cognitive impairment. However, #neuroplasticity is known to be preserved throughout #lifespan and #physical #training studies with seniors could reveal volume increases in the #hippocampus (#HC), a #region #crucial for #memory #consolidation, #learning and #navigation in #space, which were related to improvements in #aerobic #fitness. Moreover, a #positive #correlation between left #HC #volume and balance #performance was observed. Dancing seems a promising intervention for both improving balance and brain structure in the elderly. It combines aerobic fitness, #sensorimotor #skills and #cognitive demands while at the same time the risk of #injuries is low. Hence, the present investigation compared the effects of an 18-month dancing #intervention and #traditional #health #fitness #training on volumes of #hippocampal #subfields and balance abilities. Before and after intervention, balance was evaluated using the #Sensory #Organization #Test and HC volumes were derived from #magnetic #resonance #images (#3T, #MP-RAGE). Fourteen members of the dance (67.21 ± 3.78 years, seven females), and 12 members of the fitness group (68.67 ± 2.57 years, five females) completed the whole study. Both groups revealed hippocampal volume increases mainly in the left HC (CA1, CA2, subiculum). The dancers showed additional increases in the left dentate #gyrus and the right subiculum. Moreover, only the dancers achieved a significant increase in the balance composite score. Hence, dancing constitutes a promising candidate in counteracting the age-related decline in physical and mental abilities.

♻️بررسی تاثیر #مودافینیل بر درمان #خستگی در بیماری #تصلب #چندگانه

#Meta-analysis of the #efficacy of #modafinil versus #placebo in the #treatment of #multiple #sclerosis #fatigue

پژوهشگران گوانگجو 🇨🇳، دانشگاه گوانگ دونگ 🇨🇳، و دانشگاه سون یات سن 🇨🇳 در پژوهشی #فراتحلیلی به بررسی سودمندی مودافینیل در کاهش خستگی بیماران مبتلا به مالتیپل اسکلروسیس پراختند.
📚نتایج این بررسی نشان دادند پژوهش های اندکی (تنها 5 پژوهش) به بررسی مقایسه ای اثر مودافینیل بر کاهش خستگی اختصاص یافته اند. نتایج بدست آمده در مورد تاثیرات مثبا مودافینیل با توجه به کمی پژوهش های مرتبط، قطعیت بالا ندارند. در کل بخ نظر می رسد مودافینیل نسبت به دارونما تاثیرات معناداری برای کاهش خستگی بیماران مبتلا به اسکلروز مالتیپل دارد.

Abstract
Background: #Clinical #trials examining the #therapeutic benefit of #modafinil in #MS #fatigue provide #conflicting data. The goal of this study was to systematically evaluate the efficacy of modafinil using a meta-analytic method.
Methods: A systematic literature search was performed on published peer reviewed articles from 2000 to 2017 using the #Cochrane #Library, #PubMed, and #EMBASE. This review included double blind, randomized controlled trials, which evaluated modafinil in MS fatigue. The primary outcome measure was the estimated treatment difference in the #Modified #Fatigue #Impact #Scale #score (#MFIS) and #Fatigue #Severity Scale score (#FSS). A secondary outcome measure was the estimated treatment difference in the #Symbol #Digit #Modalities #Test (#SDMT).
Results: A total of 303 patients from five randomized controlled trials were included in the analyses. Modafinil was superior to #placebo with an estimated treatment difference according to the MFIS (MD = −5.27, 95% CI: −8.51 to −2.03, P = 0.001). For the FSS, there was no significant difference between the two groups (MD = 2.50, 95%CI: −0.70 to 5.70, P = 0.13). For the secondary outcome, there was no significant difference between groups studied using the SDMT (MD = 0.23, 95% CI: −0.25 to 0.71, P = 0.35).
Conclusions: Our meta-analysis showed that modafinil was an effective #pharmacologic therapy for MS fatigue. Additional research is required to determine optimal dosing and treatment schedules.
