Empowering Minds and Bodies: The Impact of Exercise on Multiple Sclerosis and Cognitive Health.

Multiple sclerosis (MS) is a global health concern affecting around 2.6 million people. It is characterised by neural inflammation, myelin breakdown and cognitive decline. Cognitive impairment, especially reduced cognitive processing speed (CPS), which affects up to 67% of MS patients and frequently manifests before mobility concerns, is one of the disease's most serious side effects. Effective adaptation and the application of cognitive rehabilitation treatments depend on the early diagnosis of cognitive impairment. Although pharmaceutical therapies have some drawbacks, endurance training has become a promising alternative. Intensity-controlled endurance exercise has the ability to delay the onset of MS symptoms and enhance cognitive function. Exercise has also been shown to have neuroprotective effects in a number of neurological disorders, including MS, Parkinson's disease and stroke. This includes both aerobic and resistance training. A mix of aerobic exercise and weight training has shown promise, especially for people with mild cognitive impairment, but according to recent studies any amount of physical activity is beneficial to cognitive performance. In conclusion, this in-depth analysis highlights the crucial part endurance exercise plays in treating MS-related cognitive impairment. It improves not only neurological health in general but also cognitive performance. Exercise can help control MS in a way that dramatically improves quality of life and well-being.

Effect of cognitive multisensory rehabilitation on upper extremity function in stroke patients: A randomized controlled trial

The aim of this study was to examine the impact of upper extremity (UE) rehabilitation based on neurocognitive multisensory therapy in stroke patients, focusing on assessing its effects on the recovery of UE function and suggesting it as a post-stroke therapeutic method. The study was conducted as a randomized, prospective, controlled trial with a pre- and post-experimental design. Thirty stroke patients were equally divided into study and control groups and evaluated before and after treatment. Outcome measures included the Action Research Arm Test (ARAT), Manual Function Test (MFT), Motor Evaluation Scale for Upper Extremity in Stroke Patients (MESUPES), and Fugl Myer Assessment upper extremity (FMA-UE). Both groups received a specific physiotherapy program, while the study group also received Cognitive Multisensory Rehabilitation (CMR). All analyses were performed using SPSS (version 25). There were no significant differences between the groups in age, weight, height, BMI, duration of illness, MMSE, sex, or spasticity grade distribution (p > 0.05). Post-treatment comparison between both groups showed a statistically significant increase in the ARAT, MFT, MESUPES, and FMA-UE scores in the study group compared to the control group (p < 0.05). For stroke patients, CMR intervention is considered a beneficial neuro-rehabilitation strategy for enhancing upper extremity sensorimotor capabilities through physical therapy.

Mapping the landscape: A bibliometric analysis of information and communication technology adoption by older adults with cognitive frailty or impairment.

The adoption of information and communication technology (ICT) by older adults with cognitive frailty and impairment is beneficial to support aging in place and promote healthy aging. However, data are scarce regarding the use of ICT by this demographic in comparison with other age groups. This bibliometric analysis was aimed at systematically mapping the literature on ICT-related research on older adults with cognitive frailty and cognitive impairment to provide insights into research trends, patterns and knowledge gaps. Data were extracted from the Web of Science database, which identified 324 publications between 1980 and 2023. Performance analysis and science mapping were carried out using Microsoft® Excel, VOSViewer and Harzing's Publish or Perish. The analysis showed an upsurge in the research output trend over time. Notable journals, authors, citations, nations and research areas have been documented. Four key clusters were identified, including: (i) caregiver concern, support and involvement; (ii) technology as a tool for cognitive training and cognitive rehabilitation; (iii) cognitive improvement; and (iv) the use of technology for prevention and self-management. The findings derived from this analysis provide an appropriate reference for future researchers to bridge the gap in ICT-related studies among this population, and distinguish the relevant articles that are required for further investigation. These include the need for further long-term research, the incorporation of ICT-based approaches to counter cognitive frailty and the importance of multidomain telehealth interventions.

Exploring the Remediation of Behavioral Disturbances of Spatial Cognition in Community-Dwelling Senior Citizens with Mild Cognitive Impairment via Innovative Technological Apparatus (BDSC-MCI Project): Protocol for a Prospective, Multi-Center Observational Study.

Spatial navigation (SN) has been reported to be one of the first cognitive domains to be affected in Alzheimer's disease (AD), which occurs as a result of progressive neuropathology involving specific brain areas. Moreover, the epsilon 4 isoform of apolipoprotein-E (APOE-ε4) has been associated with both sporadic and familial late-onset AD, and patients with mild cognitive impairment (MCI) due to AD are more likely to progressively deteriorate. Spatial navigation performance will be examined on a sample of 76 community-dwelling senior citizens (25 healthy controls; 25 individuals with subjective cognitive decline (SCD); and 26 patients with MCI due to AD) via a virtual computer-based task (i.e., the AppleGame) and a naturalistic task (i.e., the Detour Navigation Test-modified version) for which a wearable device with sensors will be used for recording gait data and revealing physiological parameters that may be associated with spatial disorientation. We expect that patients with MCI due to AD and APOE-ε4 carriers will show altered SN performances compared to individuals with SCD and healthy controls in the experimental tasks, and that VR testing may predict ecological performance. Impaired SN performances in people at increased risk of developing AD may inform future cognitive rehabilitation protocols for counteracting spatial disorientation that may occur during elders' traveling to unfamiliar locations. The research protocol has been approved by the Ethics Committee of the Istituto Auxologico Italiano. Findings will be published in peer-reviewed medical journals and discussed in national and international congresses.

Cognitive Rehabilitation for Adult Patients With Obsessive-compulsive Disorder: A Systematic Review of Randomized Controlled Trials.

Obsessive-compulsive disorder (OCD) is a disabling mental condition. Many studies have shown that OCD patients have cognitive deficits in various aspects of their cognition, which is a worsening factor of symptom severity, a potential endophenotype, insight predictor, and prognostic indicator of OCD. We designed this systematic review to evaluate the clinical efficacy of cognitive rehabilitation in cognitive deficits and symptom severity of patients with OCD following the PRISMA guidelines. We searched PubMed, Scopus, ScienceDirect, Google Scholar, and Cochrane Library using the MeSH terms and keywords of 'cognitive rehabilitation' and 'obsessive-compulsive disorder'. The database search identified 200 records of interest, and then 105 duplicates were removed from them. From 95 remaining studies, six articles were eligible for the study and met the inclusion criteria. The six articles described individual RCT studies representing a wide variety of study designs. The six included studies investigated the effect of "organizational training", "cognitive remediation", "attention splitting" and "goal management training" on cognitive impairments and symptom severity of OCD patients.There are a small number of studies with different designs and some biases that have examined the effectiveness of cognitive rehabilitation in OCD patients, with conflicting results regarding the effect of cognitive rehabilitation on OCD symptom severity or cognitive deficit. According to the results, we cannot conclude about the efficacy of cognitive rehabilitation in adults with OCD. Considering the importance of cognitive deficits in OCD patients, it is necessary to design and conduct standard trials to investigate the role of cognitive rehabilitation in these disorders.

Effectiveness of cognitive rehabilitation in comparison with routine rehabilitation methods in patients with multiple sclerosis: A systematic review and meta-analysis.

Cognitive rehabilitation includes a set of programs to train the brain, which leads to the improvement of mental and neuro-psychological functions. This meta-analysis was conducted with the aim of investigating the effectiveness of cognitive rehabilitation in comparison with routine rehabilitation methods in patients with multiple sclerosis (MS). The Cochrane Library, ProQuest, PubMed, PsycINFO, and Web of Science databases were searched from inception to August 2022. Google Scholar was used to find relevant sources and complete the search coverage. Two authors independently selected studies based on predefined inclusion criteria. Data analysis was performed using RevMan (version 5.3). Out of the 578 studies found, 20 studies were finally included in this review. The results of the meta-analysis on four outcomes (Paced Auditory Serial Addition Test (PASAT), Brief Visuospatial Memory Test (BVMT), MS Neuropsychological Screening Questionnaire (MSNQ), and Beck Depression Inventory (BDI)) indicated that the outcome was significant in favor of the cognitive rehabilitation group. However, for five outcomes (Controlled Oral Word Association Test (COWAT), California Verbal Learning Test (CVLT), Everyday Memory Questionnaire (EMQ), Symbol Digit Modalities Test (SDMT), and Expanded Disability Status Scale (EDSS)), the differences between the two groups were not significant. The results of this meta-analysis showed that cognitive rehabilitation has an effect on improving the performance of patients with MS. However, further studies with more accurate methodologies are required to determine which of the outcomes cognitive rehabilitation has a greater effect on.

Exploring the associations between physical activity level, cognitive performance, and response to computerized cognitive training among chronic stroke patients

AbstractBackgroundPost‐stroke attentional and working memory deficits are common and represent relevant predictors of long‐term functional recovery and outcome. The individual responses to cognitive rehabilitation and interventions vary between patients and are influenced by multiple factors. Recently, a link between the level of engagement in physical activities and cognitive rehabilitation has been suggested. However, few previous studies have tested the predictive value of physical activity on cognitive performance and response to cognitive training among chronic stroke patients. There is also a lack of knowledge concerning the prognostic value of index stroke characteristics on physical activity in chronic phase.MethodIn this cross‐sectional and longitudinal study, including stroke survivors suffering mild‐to‐moderate strokes (n = 52, mean age = 70 years), we used Bayesian regression to test the association between cognitive performance and response to a 3‐week intervention with a commonly used computerized cognitive training (CCT) system and baseline physical activity level measured with International Physical Activity Questionnaire. We also tested the association between physical activity level in chronic phase and stroke characteristics, including stroke severity (National Institutes of Health Stroke Scale), ischemic stroke etiology (Trial of Org 10172 in Acute Stroke Treatment), and stroke location (n = 66, mean age = 68 years). For descriptive purposes, we included 104 sex‐ and age‐matched healthy controls (mean age = 69 years).ResultsThe analyses revealed anecdotal evidence of a positive association between overall cognitive performance and daily minutes of sedentary behavior, indicating that better cognitive performance was associated with more daily hours of sitting still. We found no support for an association between cognitive performance and response to CCT with activity level. In addition, the analysis showed group differences in sedentary behavior between patients with small‐vessel disease (n = 20) and cardioembolism (n = 7), indicating more sedentary behavior in patients with small‐vessel disease. There was no further support for a predictive value of index stroke characteristics on physical activity level.ConclusionThe results do not support that baseline physical activity level is a relevant predictor of the overall performance or response to CCT in this sample of chronic stroke patients. Similarly, the analyses revealed little evidence for an association between index stroke characteristics and future activity level in patients surviving mild‐to‐moderate stroke.

Chemotherapy-induced cognitive impairment in breast cancer survivors: A systematic review of studies from 2000 to 2021.

Studies have indicated that apart from enhancing patient survival, chemotherapy has adverse side effects on the psychological, social, and cognitive functions of breast cancer survivors. This study was conducted to understand chemotherapy's impact on breast cancer survivors' cognitive functions. Our study is a systematic review based on the Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) statement. We searched English databases, including PubMed/MEDLINE, PsycINFO, and Web of Science, and Persian databases, such as Irandoc and Elmnet, using Persian keywords of cancer, breast cancer, chemotherapy, cognitive functions, executive functions, and neuropsychological functions. Two reviewers independently evaluated the full text of the articles according to predefined criteria. Among the 937 available studies, 26 were selected based on the inclusion and exclusion criteria, of which 17 (65%) were longitudinal and 9 (35%) were cross-sectional. The findings indicated a significant relationship between the use of chemotherapy and cognitive impairments, most notably attention, working and short-term memory, and executive functions. However, the studies differed in their findings regarding the long-term persistence of cancer-related cognitive impairment (CRCI), which could be due to the wide range of tools used, different methods to measure cognitive functions, and the difference in the sample size of the studies. Chemotherapy, affecting cortical and subcortical brain structures, causes a set of cognitive impairments that can lead to impairments in social responsibility acceptance, daily functioning, and quality of life of women. Therefore, rigorous and extensive research design is required to understand the causes and consequences of CRCI using standardized and sensitive measures of cognitive functions. Specifically, studies comparing the effects of different chemotherapy regimens on cognition and potential mechanisms and/or moderators of CRCI would be instrumental in designing more effective therapy regimens and evaluating the efficacy and cost-effectiveness of cognitive rehabilitation and supportive care programs.

Social cognitive disruptions in multiple sclerosis: The role of executive (dys)function.

Multiple sclerosis (MS) is a chronic demyelinating disease of the central nervous system, resulting in a range of potential motor and cognitive impairments. The latter can affect both executive functions that orchestrate general goal-directed behavior and social cognitive processes that support our ability to interact with others and maintain healthy interpersonal relationships. Despite a long history of research into the cognitive symptoms of MS, it remains uncertain if social cognitive disruptions occur independently of, or reflect underlying disturbances to, more foundational executive functions. The present preregistered study investigated this directly. Employing an experimental design, we administered a battery of computerized tasks online to a large sample comprising 134 individuals with MS and 134 age- and sex-matched healthy controls (HCs). Three tasks measured elements of executive function (working memory, response inhibition, and switching) and two assessed components of social cognition disrupted most commonly in MS (emotion perception and theory of mind). Individuals with MS exhibited poorer working memory (d = .31), response inhibition (d = -.26), emotion perception (d = .32), and theory of mind (d = .35) compared with matched HCs. Furthermore, exploratory mediation analyses revealed that working memory performance accounted for approximately 20% of the group differences in both measures of social cognition. Disruptions to working memory appear to serve as one of the mechanisms underpinning disturbances to social cognition in MS. Future research should examine if the benefits of cognitive rehabilitation programs that incorporate working memory training transfer to these social cognitive processes.

The effect of processing speed on verbal and visual memory of adults with a chronic acquired brain injury

ABSTRACT Objective Memory problems are among the most frequently reported cognitive complaints by individuals with an acquired brain injury (ABI). Processing speed and working memory deficits are often the result of ABI. These cognitive deficits significantly impact the acquisition and retention of information necessary for memory formation. This study investigated the influence of processing speed and working memory on immediate and delayed recall for verbal and visual memory, as well as overall memory recall in adults living with a chronic ABI. Methods Sixty-three participants living with a chronic ABI, who were at least one-year post-injury, were cognitively assessed with the CNS-Vital Signs (CNS-VS) computerized cognitive battery and Wechsler Test of Adult Reading. Results The CNS-VS Processing Speed significantly predicted delayed recall for verbal memory and overall memory performance. The CNS-VS Working Memory was not a significant predictor of memory recall. Conclusions Processing speed deficits negatively impact memory in individuals with a chronic ABI. These findings suggest the memory recall of adults with a chronic ABI is associated with poor processing speed and poor acquisition of information. Therefore, cognitive rehabilitation that improves processing speed should be the focus for individuals with ABI to improve memory performance as well as impaired processing speed.

Neurophysiological brain function predicts response to cognitive rehabilitation and mindfulness in multiple sclerosis: a randomized trial

BackgroundCognitive treatment response varies highly in people with multiple sclerosis (PwMS). Identification of mechanisms is essential for predicting response.ObjectivesThis study aimed to investigate whether brain network function predicts response to cognitive rehabilitation therapy (CRT) and mindfulness-based cognitive therapy (MBCT).MethodsPwMS with cognitive complaints completed CRT, MBCT, or enhanced treatment as usual (ETAU) and performed three measurements (baseline, post-treatment, 6-month follow-up). Baseline magnetoencephalography (MEG) measures were used to predict treatment effects on cognitive complaints, personalized cognitive goals, and information processing speed (IPS) using mixed models (secondary analysis REMIND-MS study).ResultsWe included 105 PwMS (96 included in prediction analyses; 32 CRT, 31 MBCT, 33 ETAU), and 56 healthy controls with baseline MEG. MEG did not predict reductions in complaints. Higher connectivity predicted better goal achievement after MBCT (p = 0.010) and CRT (p = 0.018). Lower gamma power (p = 0.006) and higher connectivity (p = 0.020) predicted larger IPS benefits after MBCT. These MEG predictors indicated worse brain function compared to healthy controls (p < 0.05).ConclusionsBrain network function predicted better cognitive goal achievement after MBCT and CRT, and IPS improvements after MBCT. PwMS with neuronal slowing and hyperconnectivity were most prone to show treatment response, making network function a promising tool for personalized treatment recommendations.Trial registrationThe REMIND-MS study was prospectively registered in the Dutch Trial registry (NL6285; https://trialsearch.who.int/Trial2.aspx?TrialID=NTR6459).

Effects of repetitive transcranial magnetic stimulation combined with cognitive training on cognitive function in patients with Alzheimer’s disease: a systematic review and meta-analysis

PurposeTo evaluate the effect of repetitive transcranial magnetic stimulation (rTMS) paired with cognitive training on cognitive function in Alzheimer’s Disease (AD) patients.MethodsPubMed, The Cochrane Library, Embase, CINAHL Complete (EBSCO), China National Knowledge Infrastructure (CNKI) and WanFang Database were searched. The risk of bias was appraised through the Cochrane collaboration tool. A meta-analysis was conducted, including an assessment of heterogeneity.ResultsTen studies comprising 408 participants were included. The addition of rTMS significantly improved overall cognition in patients compared with cognitive intervention alone (p &amp;lt; 0.05 for all tests). The treatment also had some continuity, with significant improvements in cognitive function within weeks after the treatment ended (p &amp;lt; 0.05 for all tests).ConclusionRepetitive transcranial magnetic stimulation combined with cognitive training (rTMS-CT) is a valuable technique for the cognitive rehabilitation of AD patients. It is beneficial to improve the cognitive ability of patients and restore their overall functional state. The results of the study may provide a basis for clinical providers to implement interventions that facilitate the design of more rigorous and high-quality interventions.LimitationsThe number of studies and sample size in our study were small. We did not explore possible interactions between rTMS and medications and mood improvement after rTMS due to inadequate data.Systematic review registrationThis study was registered on PROSPERO with registration number CRD42023405615.

Cognition in vestibular disorders: state of the field, challenges, and priorities for the future.

Vestibular disorders are prevalent and debilitating conditions of the inner ear and brain which affect balance, coordination, and the integration of multisensory inputs. A growing body of research has linked vestibular disorders to cognitive problems, most notably attention, visuospatial perception, spatial memory, and executive function. However, the mechanistic bases of these cognitive sequelae remain poorly defined, and there is a gap between our theoretical understanding of vestibular cognitive dysfunction, and how best to identify and manage this within clinical practice. This article takes stock of these shortcomings and provides recommendations and priorities for healthcare professionals who assess and treat vestibular disorders, and for researchers developing cognitive models and rehabilitation interventions. We highlight the importance of multidisciplinary collaboration for developing and evaluating clinically relevant theoretical models of vestibular cognition, to advance research and treatment.

The nature of memory impairment in multiple sclerosis: understanding different patterns over the course of the disease.

Memory deficit is one of the most common and severe cognitive impairments in patients with multiple sclerosis and can greatly affect their quality of life. However, there is currently no agreement as to the nature of memory deficit in multiple sclerosis. This cross-sectional study, carried out at the Dr. Josep Trueta and Santa Caterina hospitals in Girona (Spain), was designed to determine the semiology of verbal memory deficit in the different stages of the disease. To this end, a modification of Rey's verbal auditory test was created by introducing two recognition trials between the five learning trials, thus monitoring what happens in terms of acquisition versus the retrieval of information during the learning phase. Linear regression models were used to evaluate verbal episodic memory performance between-groups adjusting results by age, sex, educational level, and the presence of anxiety and/or depressive symptoms. 133 patients with multiple sclerosis, clinically isolated syndrome, and radiologically isolated syndrome and 55 healthy controls aged 18-65 years were assessed. It was observed that the memory processes of multiple sclerosis patients worsen with the progression of the disease. In this respect, patients in pre-diagnostic phases (radiologically isolated syndrome and clinically isolated syndrome) show no differences in verbal episodic memory compared to the healthy controls. Patients in the inflammatory stage (relapsing-remitting multiple sclerosis) show a previously learned information retrieval deficit, while patients in progressive stages (secondary progressive multiple sclerosis and primary progressive multiple sclerosis) do not even correctly acquire information. These results provide significant information to assist in understanding the nature of memory deficits in multiple sclerosis over the course of the disease. These results are discussed in terms of possible cognitive rehabilitation strategies depending on the evolutive stage and are related to neuropathological mechanisms involved in the progression of the disease.

Changes in patients’ religiosity related to dementia

Dementia is characterized by the presence of progressive cognitive and behavioral symptoms which affect normal functioning. With the purpose of determining if there are any changes related to patients’ religiosity due to dementia, we developed a questionnaire aiming to evaluate changes pre and post diagnostic. In effect, we observed that patients with dementia might experience a reduction of the importance given to religion and its associated practices with the disease progression. However, God’s belief did not show any changes despite the diagnosis. Therefore, we point out the relevance of incorporating religiosity as another aspect to take into account in the cognitive rehabilitation treatments.

Enhancing cognitive flexibility and working memory in individuals with mild cognitive impairment: Exploring the impact of virtual reality on daily life activities

Mild Cognitive Impairment (MCI) serving as a transitional stage between normal aging and dementia. This study aimed to explore the impact of virtual reality (VR) on enhancing cognitive flexibility, working memory, and daily life activities. Forty participants diagnosed with MCI were randomly assigned to either an intervention group (N = 20) or a control group (N = 20). Evaluations were at baseline, post-training, and three months post-training using various cognitive assessment tools. Results showed that the VR-based cognitive rehabilitation significantly improved instrumental activities of daily living performance, visual and verbal working memory, and reduced anxiety and depression symptoms. While cognitive flexibility did not exhibit significant improvement, these findings highlight VR interventions as a potential avenue for improving cognitive and functional aspects, and alleviating psychological symptoms in individuals with MCI. Further research with larger sample sizes and extended follow-up periods is recommended to establish the long-term effectiveness of such interventions.

Comparing the Effectiveness of Mindfulness-based Stress Reduction Training and Powell’s Cognitive Rehabilitation on Improving the Quality of Life of Stroke Patients

Background: Stroke is a type of neurological disorder that can be attributed to a central vascular cause. Stroke can affect the patient’s performance in daily activities and quality of life (QoL). Research indicates a decrease in the quality of life in stroke patients due to cognitive and emotional damage. Objectives: The present study compared the effect of two group approaches, mindfulness training based on stress reduction and Powell’s cognitive rehabilitation, on improving the quality of life of stroke patients. Methods: This semi-experimental study used a pretest-posttest design with a control group and a follow-up period. The sample consisted of 36 eligible stroke patients selected in a targeted and simple random manner. The patients were divided into two intervention groups and one control group. The tools used were a demographic information questionnaire and a Stroke-specific QoL (SS-QOL) scale. Data were analyzed with SPSS software (version. 26). Chi-square, repeated measures analysis of variance, and Bonferroni statistical tests were applied at a significance level of P 0.05). The mindfulness intervention had a higher effect on quality of life on average. Still, statistically, none of the interventions were effective in improving quality of life (P &gt; 0.05), and there was no significant difference between the effect of mindfulness-based methods and cognitive rehabilitation on improving quality of life (P &gt; 0.05). Conclusions: Mindfulness training increases behavioral responses related to attention as the basis of all cognitive activities. Also, mindfulness exercises improve cognitive skills and, by affecting the cognitive system, increase the capacity and ability of the information processing system and improve the quality of life.

Knowledge, attitude, and practice of healthcare professionals toward cognitive dysfunction in Parkinson’s disease and cognitive rehabilitation

BackgroundTo investigate the knowledge, attitude, and practice (KAP) of healthcare professionals regarding cognitive dysfunction and cognitive rehabilitation in Parkinson’s disease (PD).MethodsThis multicenter, cross-sectional survey enrolled physicians and nurses in 10 hospitals between October 2022 and November 2022. A self-administered questionnaire was developed to collect the demographic information of the participants and their knowledge, attitude, and practice toward cognitive dysfunction in PD and cognitive rehabilitation.ResultsThis study enrolled 224 physicians and 229 nurses. The knowledge, attitude, and practice scores were 12.57 ± 3.76 (total score: 22), 29.10 ± 3.71 (total score: 32), and 21.07 ± 8.03 (total score: 28) among physicians, and 9.97 ± 4.70 (total score: 22), 25.27 ± 8.96 (total score: 32), and 25.27 ± 8.96 (total score: 28) among nurses. Among physicians, the knowledge scores (OR = 4.23, 95%CI: 2.36–7.58, P < 0.001) and attitude scores (OR = 3.00, 95%CI: 1.67–5.37, P < 0.001) were independently associated with good practice. Among nurses, the knowledge scores (OR = 4.31, 95%CI: 2.31–8.05, P < 0.001), attitude scores (OR = 5.18, 95%CI: 2.82–9.53, P < 0.001), working department (Ref: rehabilitation; neurology: OR = 2.26, 95%CI: 1.01–5.08, P = 0.048; public health service/chronic disease follow-up center: OR = 2.98, 95%CI: 1.12–7.92, P = 0.028) were independently associated with good practice.ConclusionsPhysicians and nurses have insufficient knowledge, favorable attitudes, and active practice regarding cognitive dysfunction and cognitive rehabilitation in PD. This study identified gaps in KAP and suggested education activities to improve the KAP toward cognitive dysfunction in PD.

Comparative Effects of Cognitive Rehabilitation and Photobiomodulation on Drug Craving in Treatment-Seeking Opioid Addicts.

Background: Drug addiction refers to a maladaptive pattern of drug use that frequently leads to substance abuse problems and accompanying cognitive and behavioral symptoms. Among the crucial criteria of drug addiction, craving stands out as a potent factor contributing to ongoing drug abuse and relapse following period of abstinence. To date, there is no definitive method for eradicating opioid cravings. The introduction of novel neurocognitive interventions, such as cognitive rehabilitation and photobiomodulation (PBM), into the realm of psychiatric treatments holds promise due to the parallels between drug addiction and other psychiatric disorders. These innovative techniques offer potential value in addressing drug addiction. Objective: This study aimed to assess and compare the efficacy of cognitive rehabilitation and PBM in alleviating drug cravings among individuals undergoing addiction treatment in clinical settings. Methods: The research used randomized clinical trial as the chosen research method. The statistical population encompassed all clients receiving treatment for addiction at clinics, selected through the convenience sampling method, with α = 0.05 significance level and an effect size of 85%. Gpower software was utilized to determine three equal groups. Sixty-three participants, each having a mean total score higher than 3 out of 5 on the Desire for Drug Questionnaire (DDQ), were randomly assigned to two experimental groups (n = 21 each) and a control group (n = 21). For the assessment of immediate and periodic opioid craving, the DDQ and the Obsessive Compulsive Drug Use Scale were used. In the low-level laser group, an 810 nm wavelength with continuous irradiation was applied twice a week at a distance of 1 cm by 1 cm to the prefrontal part of the brain for duration of 6 weeks (12 sessions). In the brain rehabilitation group, the stop signal and n-back tasks software were used twice a week for period of 6 weeks (comprising 12 sessions, each lasting 30 min). Results: The results demonstrated that each intervention significantly reduced drug craving in both the post-test and follow-up phases compared to the control group. The Bonferroni post hoc test indicated that PBM was more effective than cognitive rehabilitation in terms of working memory (WM) and inhibitory control for reducing drug craving (p < 0.05). Conclusions: While both PBM and cognitive rehabilitation targeting WM and inhibitory control effectively reduced opioid drug craving, low-level laser therapy proved to be more effective than cognitive rehabilitation in this regard.
