#Cognitive #rehabilitation #therapies for #Alzheimer's disease: A #review of methods to #improve #treatment #engagement and #self_efficacy
Neuropsychol Rev. 2013 Mar; 23(1): 48–62.
Abstract
Cognitive rehabilitation therapies for Alzheimer’s disease (AD) are becoming more readily available to the geriatric population in an attempt to curb the insidious decline in cognitive and functional performance. However, people with AD may have difficulty adhering to these cognitive treatments due to denial of memory deficits, compromised brain systems, cognitive incapacity for self-awareness, general difficulty following through on daily tasks, lack of motivation, hopelessness, and apathy, all of which may be either due to the illness or be secondary to depression. Cognitive rehabilitation training exercises are also labor intensive and, unfortunately, serve as a repeated reminder about the memory impairments and attendant functional consequences. In order for cognitive rehabilitation methods to be effective, patients must be adequately engaged and motivated to not only begin a rehabilitation program but also to remain involved in the intervention until a therapeutic dosage can be attained. We review approaches to cognitive rehabilitation in AD, neuropsychological as well as psychological obstacles to effective treatment in this population, and methods that target adherence to treatment and may therefore be applicable to cognitive rehabilitation therapies for AD. The goal is to stimulate discussion among researchers and clinicians alike on how treatment effects may be mediated by engagement in treatment, and what can be done to enhance patient adherence for cognitive rehabilitation therapies in order to obtain greater cognitive and functional benefits from the treatment itself.
Keywords: cognitive rehabilitation, treatment engagement, adherence, motivation

مشخص شدن دلیل #تصمیم گیری های #غیرعقلانی: #میانبرهای #روانی، نه #هیجانات، عامل #خطاهای #تصمیم گیری هستند.
#Reason's #Enemy Is Not #Emotion: Engagement of #Cognitive #Control #Networks #Explains #Biases in #Gain/#Loss #Framing
#سوگیری های نادرست در تصمیم گیری های #انسانی به طور غالب به #هیجانات اسناد داده می شوند. در پژوهشی که به تازگی منتشر شده است، محققان نوروساینس دانشگاه #دوک در کارولینای شمالی 🇺🇸 به بررسی #تصاویر #مغزی کامل افراد پرداختند تا #مدارهای #عصبی مرتبط با تصمیم گیری را بررسی و واکاوای نمایند
در این پژوهش داده های #fMRI حاصل از 143 نفر داوطلب به همراه #فراتحلیل داده های بیش از 8000 تصویربرداری مغزی مورد واکاوی قرار گرفتند.
نتایج نشان دادند که هنگام #تصمیم گیری های نادرست، الگوهای فعالیت مغزی در مدارهای هیجانی نبوده اند بلکه در مدارهای شناختی متمایز از مدارهای معمول پردازشی رخ داده اند که به نوعی میانبرهای شناختی محسوب می شوند. این میانبرهای شناختی بعنوان #تصورات #غالبی و یا #افکار ریشه ای نیز در #رواندرمانی شناخته می شوند.
Abstract
In the #classic gain/loss #framing effect, describing a #gamble as a potential gain or loss biases people to make #risk-averse or #risk-seeking decisions, respectively. The canonical explanation for this effect is that frames differentially modulate #emotional processes, which in turn leads to #irrational choice #behavior. Here, we evaluate the source of framing biases by integrating functional magnetic resonance imaging (#fMRI) data from 143 human participants performing a gain/loss framing task with #meta-analytic data from >8000 #neuroimaging studies. We found that activation during choices consistent with the framing effect were most correlated with activation associated with the resting or default brain, while activation during choices inconsistent with the framing effect was most correlated with the task-engaged brain. Our findings argue against the common interpretation of gain/loss framing as a competition between #emotion and #control. Instead, our study indicates that this effect results from #differential #cognitive #engagement across decision frames.

♻️کشف علت #نقص #توجه و #ضعف #عمکرد در بزرگسالان دارای اختلالات طیف #بیش_فعالی و #نقض_توجه (#ADHD)
Increased #default-mode #variability is related to reduced #task-performance and is evident in #adults with #ADHD
پژوهشگران روانشناسی و روانپزشکی دانشگاه اسلو 🇳🇴 و دانشکاه کینگزکالج 🇬🇧 در پژوهشی مشترک دریافتند افزایش تغییر در #وضعیت #شبکه #پایه #مغز (#DMN) منجر به کاهش #دقت و افت #عملکرد در افراد دارای ADHD شده و در بزرگسالی نیز ادامه دارد.
🔬در این پژوهش آزمایشی که بر 20 بزرگسال دارای ADHD و 27 بزرگسال سالم در سنین 18 تا 40 سال صورت گرفت، آزمون های #کارکردهای #اجرایی و نیز #fMRI درکنار #آزمایش #خون بعمل آمدند. همچنین، افراد دارای ADHD بصورت نامشخص هم بعد از مصرف #میتل_فنیدیت (#MPH) و هم بعد از مصرف #دارونما مورد ارزیابی قرار گرفتند.
📚نتایج نشان دادند که فعالیت DMN در افراد دارای ADHD بدون مصرف دارو بسیار بیشتر از افراد سالم است. همچنین ارتباط عملکردی بین شبکه های توجه و DMN به کارکرد و وضعیت کنترل داوطلب نیز وابسته بود. بر این اساس بنظر می رسد #دارودرمانی نمی تواند تمامی #مدارهای #عصبی را در افراد دارای ADHD کنترل نماید؛ بویژه فرآیندهای #کنترل #تکانه و #تصمیمگیری که متیل فنیدیت بر آنها بی تاثیر است.
Abstract
#Insufficient #suppression and #connectivity of the #default #mode #network (#DMN) is a potential #mediator of #cognitive #dysfunctions across various disorders, including #attention #deficit/#hyperactivity #disorder (#ADHD). However, it remains unclear if alterations in #sustained DMN suppression, variability and connectivity during prolonged #cognitive #engagement are implicated in #adult ADHD #pathophysiology, and to which degree #methylphenidate (#MPH) remediates any DMN #abnormalities. This #randomized, #double-blinded, #placebo-controlled, #cross-over #clinical #trial of #MPH (clinicaltrials.gov/ct2/show/NCT01831622) explored large-scale brain network dynamics in 20 adults with ADHD on and off MPH, compared to 27 healthy controls, while performing a reward based #decision-making task. DMN task-related #activation, variability, and connectivity were estimated and compared between groups and conditions using #independent #component #analysis, #dual #regression, and #Bayesian #linear #mixed #models. The results show that the DMN exhibited more variable activation patterns in unmedicated patients compared to healthy controls. Group differences in functional connectivity both between and within functional networks were evident. Further, functional connectivity between and within attention and DMN networks was sensitive both to task performance and case-control status. MPH altered within-network connectivity of the DMN and visual networks, but not between-network #connectivity or #temporal variability. This study thus provides novel #fMRI evidence of reduced sustained DMN suppression in adults with ADHD during value-based decision-making, a pattern that was not alleviated by MPH. We infer from multiple analytical approaches further support to the #default #mode #interference #hypothesis, in that higher DMN activation variability is evident in adult ADHD and associated with lower task performance.
