Cognitive rehabilitation in Multiple sclerosis

Cognitive impairments are frequent in Multiple sclerosis (MS). However, most studies about efficacy of cognitive rehabilitation interventions have been criticized in terms of methods and/or design. The aim of this study is to evaluate the efficacy of cognitive rehabilitation in MS patients with a cognitive intervention (ProCogSEP* program), compared to a control intervention (discussion program). Twenty MS patients have completed this simple blind study: 10 patients followed 13 sessions (2 hours) of the ProCog-SEP¹ program. Ten other patients followed 13 sessions (2 hours) of a discussion program (Control Group). All patients underwent neuropsychological assessment, before and after their program, in order to evaluate cognitive functions. Two neuropsychologists respectively assessed the patients and conducted the group sessions. Compared to its own baseline, ProCog-SEP Group show improvements in verbal memory [free recall (p = .02), learning (p = .002)], in visual memory [free (p = .05) and delayed recall (p = .007)], in working-memory (p = .03), in verbal fluency (p = .05) and in language (p = .01). Inter group analysis show a benefit of cognitive program mainly in verbal and visual memory, and in verbal fluencies. These results support the interest of a cognitive therapeutic management of MS patients.     

tDCS combined with optokinetic drift reduces egocentric neglect in severely impaired post-acute patients

Visuospatial neglect is a disabling syndrome resulting in impaired activities of daily living and in longer durations of inpatient rehabilitation. Effective interventions to remediate neglect are still needed. The combination of tDCS and an optokinetic task might qualify as a treatment method. A total of 32 post-acute patients with left (n?=?20) or right-sided neglect were allotted to an intervention or a control group (both groups n?=?16). The intervention group received eight sessions of 1.5–2.0?mA parietal transcranial direct current stimulation (tDCS) during the performance of an optokinetic task distributed over two weeks. Additionally they received standard therapy for five hours per day. The control group received only the standard therapy. Patients were examined twice before (with 3–4 days between examinations) and twice after treatment (5–6 days between examinations). Compared to the control group and controlling for spontaneous remission, the intervention group improved on spontaneous body orientation and the Clock Drawing Test. Intragroup comparisons showed broad improvements on egocentric but not on allocentric symptoms only for the intervention group. A short additional application of tDCS during an optokinetic task led to improvements of severe neglect compared to a standard neurological early rehabilitation treatment. Improvements seem to concern primarily egocentric rather than allocentric neglect.     

Memory rehabilitation for the working memory of patients with multiple sclerosis (MS)

Objective: The main cognitive impairments in multiple sclerosis (MS) affect the working memory, processing speed, and performances that are in close interaction with one another. Cognitive problems in MS are influenced to a lesser degree by disease recovery medications or treatments,but cognitive rehabilitation is considered one of the promising methods for cure. There is evidence regarding the effectiveness of cognitive rehabilitation for MS patients in various stages of the disease. Since the impairment in working memory is one of the main MS deficits, a particular training that affects this cognitive domain can be of a great value. This study aims to determine the effectiveness of memory rehabilitation on the working memory performance of MS patients.

Method: Sixty MS patients with cognitive impairment and similar in terms of demographic characteristics, duration of disease, neurological problems, and mental health were randomly assigned to three groups: namely, experimental, placebo, and control. Patients’ cognitive evaluation incorporated baseline assessments immediately post-intervention and 5 weeks post-intervention. The experimental group received a cognitive rehabilitation program in one-hour sessions on a weekly basis for 8 weeks. The placebo group received relaxation techniques on a weekly basis; the control group received no intervention.

Results: The results of this study showed that the cognitive rehabilitation program had a positive effect on the working memory performance of patients with MS in the experimental group. These results were achieved in immediate evaluation (post-test) and follow-up 5 weeks after intervention. There was no significant difference in working memory performance between the placebo group and the control group.

Conclusions: According to the study, there is evidence for the effectiveness of a memory rehabilitation program for the working memory of patients with MS. Cognitive rehabilitation can improve working memory disorders and have a positive effect on the working memory performance of these patients.     

Treating learning impairments improves memory performance in multiple sclerosis: a randomized clinical trial

This randomized clinical trial utilized established techniques to improve new learning and memory performance in multiple sclerosis (MS) participants with learning impairment. Participants were 29 individuals with clinically definite MS with documented learning deficits, randomly assigned to the experimental or control group. The experimental group underwent eight sessions of the Story Memory Technique (SMT), while the control group participated in eight sessions of memory exercises. Neuropsychological assessment was conducted at baseline, immediately following treatment and 5 weeks later to assess outcome. When stratifying participants by degree of learning deficits, a significant treatment effect was noted. MS participants with moderate-severe impairment in learning showed a significant improvement in learning abilities when compared to controls, (t(19) =3.32, P<0.01) evident in 88% of participants in the experimental group. Little improvement was noted in MS participants with mild learning impairments. Significant self-reported improvements in memory were noted in MS participants that underwent treatment, but not those that did not undergo treatment (t(26) =2.55, P<0.01). Results indicate that learning and memory deficits in MS can be effectively treated through a memory rehabilitation program utilizing context and imagery to improve new learning. Appropriate patient selection is important, with moderately-severely impaired individuals showing significantly greater benefit from treatment.     

A meta-synthesis of qualitative research on perceptions of people with long-term neurological conditions about group-based memory rehabilitation

The effectiveness of memory rehabilitation based on randomised controlled trials and meta-analyses has been inconclusive, but patient reports based on qualitative studies have been largely positive. We conducted a meta-synthesis of qualitative studies of group-based memory rehabilitation programmes for people with neurological conditions. Based on systematic searches of electronic databases and reference lists, five papers (87 participants) were selected. Quality appraisal of papers was conducted by two independent reviewers using the Critical Appraisal Skills Programme tool. Data synthesis was guided by the meta-ethnography approach. Five higher order themes were elicited. These suggested that memory rehabilitation was associated with insight and acceptance of participants' neurological condition and resultant cognitive deficits. The therapeutic effects of the groups, with social support and leisure activities, helped with participants' confidence. There were improvements in memory related to better self-awareness and learning to use new skills and strategies to compensate for memory deficits. These improvements also related to other psychological effects, in terms of positively affected mood, confidence and fatigue. Ultimately, these changes had a positive impact on daily life, with changes seen in the personal, inter-personal and professional spheres. Therefore, this synthesis of qualitative studies suggests that memory rehabilitation offers positive outcomes for people with long-term neurological conditions.     

Further development of an illness perception intervention for myocardial infarction patients: A randomized controlled trial

Objective

To further develop and trial a brief in-hospital illness perception intervention for myocardial infarction (MI) patients.

Methods

One hundred and three patients admitted with acute MI were randomized to receive either standard care or standard care plus an illness perception intervention, which consisted of three half-hour patient sessions and one half-hour patient-and-spouse session delivered in hospital. Patients were followed up to 6 months. The main outcome was the difference between groups in rate of return to work.

Results

The intervention group had a faster rate of return to work than the control group, and more patients in the intervention group had returned to full time work by 3 months than in the control group. At discharge, patients in the intervention group demonstrated changes in causal attributions regarding their MI and higher perceived understanding of their condition, which remained at the 6-month follow-up. They also reported a better understanding of the information given in hospital, higher intentions to attend cardiac rehabilitation classes, lower anxiety about returning to work, greater increases in exercise, and made fewer phone calls to their general practitioner about their heart condition at follow-up.

Conclusion

This study replicates the findings of an earlier trial that a brief in-hospital illness perception intervention can change perceptions and improve rates of return to work in MI patients. It increases the generalizability of the intervention to the current broader definition of MI and to patients who have had previous infarcts.     

Lessons learned: Outcomes and methodology of a coping skills intervention trial comparing individual and group formats for patients with cancer

OBJECTIVE: Nucare, a short-term psychoeducational coping skills training intervention was evaluated in a randomized controlled clinical trial (RCT) of 225 newly diagnosed breast and colon cancer patients. METHOD: Measures of psychosocial distress, well being and optimism were evaluated every four months during a one-year period. Patients were randomized to one of four arms: Nucare presented in an individual basis; Nucare presented in a group format; a non-directive supportive group; and a no-intervention control. The interventions were provided in five sessions of ninety minutes each. RESULTS: Patients with breast cancer who received Nucare presented in an individual format showed more significant improvements in well-being over time compared to those in the control and group arms. CONCLUSIONS: We were unable to develop functioning groups within the RCT. Partial explanations for the latter finding include the structural limitations of the RCT: the groups were small, difficult to schedule and patients indicated that they would have preferred to choose whether or not to participate in a group. The positive changes in women with breast cancer who received Nucare persisted at 12 months.     

Effectiveness of cognitive rehabilitation for people with multiple sclerosis: a meta-synthesis of patient perspectives

While previous randomised controlled trials and meta-analyses offer only limited evidence for the effectiveness of cognitive rehabilitation, qualitative studies examining patient perspectives report more positive outcomes. This meta-synthesis of qualitative studies examined patient perspectives of cognitive rehabilitation for memory, attention, and executive function problems in people with multiple sclerosis. Using set eligibility criteria, we screened electronic databases, reference lists, and academic networks for relevant papers. Seven papers (195 participants) were selected. Two independent researchers conducted quality appraisals of papers. Data analysis, guided by the thematic synthesis approach, yielded six main themes. These suggested that patients benefitted from the group environment in rehabilitation. Cognitive rehabilitation facilitated the participants’ reflection and awareness of their cognitive deficits, and was associated with increased knowledge and understanding of their illness. Increased strategy use was reported and associated with improvements in cognitive functioning and greater confidence and perseverance. Participants reported emotional and social improvements, and felt more optimistic. Overall, these changes had a positive impact on participants’ quality of life. This synthesis of qualitative studies indicates that people with multiple sclerosis who experience cognitive deficits benefit from cognitive rehabilitation programmes. This finding must, however, be viewed in light of the limitations of this meta-synthesis. The meta-synthesis was registered in the PROSPERO database under CRD42017040148.     

Improving memory in outpatients with neurological disorders using a group-based training program

Memory problems are common in patients with a range of neurological conditions, but there have been few attempts to provide and evaluate the usefulness of memory training for groups of neurological outpatients. We used a waitlist-controlled trial design to assess the effectiveness of a newly created, 6-session intervention, which involved training in the use of compensatory strategies as well as education regarding memory function, neurological damage, sleep and lifestyle factors that have an impact on memory. Fifty-six patients with neurological conditions (e.g., stroke, epilepsy) and memory complaints completed the training and assessments. Outcomes were evaluated in terms of reported strategy use as well as objective and subjective measures of anterograde and prospective memory. Training resulted in significant improvements on number of strategies used, scores on the Rey Auditory Verbal Learning Test (total learning and delayed recall) and self-report on the Comprehensive Assessment of Prospective Memory. Improvements were stable at 3-month follow-up. Better individual outcomes were related to lower baseline memory scores, fewer symptoms of depression and greater self-awareness of memory function. Overall the study provides encouraging results to indicate that patients with neurological conditions such as stroke and epilepsy can show improvements in memory after a relatively short group-based intervention. (JINS, 2012, 18, 1-11).     

Effects of cognitive remediation on cognitive and social functions in individuals with schizophrenia

ABSTRACT

Individuals with schizophrenia exhibit cognitive impairments, which are related to impairments in social functions. This study investigated the effects of cognitive remediation on cognitive, social, and daily living impairment. Participants were individuals with schizophrenia between 20 and 60 years old (N?=?44). Participants were randomly assigned to two groups: a cognitive remediation intervention group and a non-intervention control group. The control group was provided with conventional drug therapy and either day care or occupational therapy. The intervention group was provided with the “neuropsychological educational approach to cognitive remediation” developed by Medalia and co-workers. We assessed cognitive functions using the brief assessment of cognition in schizophrenia (BACS), and evaluated social and daily living functions using the global assessment of functioning (GAF) scale. Significant group by time interaction effects indicated that verbal memory, working memory, attention, and executive function showed significantly greater improvement at post-intervention for the intervention group than the control group. Social and daily living function also improved in the intervention group and improvements were maintained one year after intervention. These preliminary findings indicate that the combination of cognitive remediation and psychiatric rehabilitation is effective for facilitating improvements in cognitive function and social and daily living functions in individuals with schizophrenia.     

Testing effectiveness of a community-based aggression management program for children 7 to 11 years old and their families

ObjectiveThere are few well-evaluated uncomplicated community-based interventions for childhood aggression. The authors assess the impact of a community-based anger management group on child aggressive behaviors, using a randomized, controlled trial (RCT).MethodFamilies with children 7 to 11 years old were recruited through advertisements and randomized (N = 123). Inclusion required parent concern about anger/aggressive behavior, RCT agreement, and a telephone behavior screen. Intervention participants were offered three parent education/skill-building group sessions, 10 weekly child group sessions, and three in-home family practice sessions. Nine groups ran from August 2002 to August 2004. Interviewers naïve to randomization collected data on all participants pre- and postgroup. Outcomes included child-rated anger and parent-rated child aggressive behavior, externalizing behavior and hostility, parent-child relationship, and parenting stress. Intent-to-treat analyses were done.ResultsPre/postoutcome comparisons indicated no significant differences between intervention versus control, with small effect sizes for most outcomes (0.27-0.29). Although not significant, the magnitude of improvement favored intervention families on all parent-rated measures.ConclusionsOverall, there was no differential impact of participating in a community-based anger management group versus control on child aggressive behaviors and other associated measures. The impact of regression to the mean, effect, and sample size estimates; child comorbidity; and programmatic and methodological issues are discussed.     

The NeuroPage system for children and adolescents with neurological deficits

Objective: Several studies have demonstrated the effectiveness of a paging system, NeuroPage, in helping survivors of brain injury compensate for everyday memory and planning problems. This study examines the effectiveness of the paging system in the sub-group of 12 children and adolescents with neurological deficits who took part in a larger study.

Methods: Twelve participants aged 8–17 years took part in a randomized controlled crossover trial in which their completion of everyday goals was monitored prior to and during use of the NeuroPage system, where participants were sent reminder messages regarding tasks they should complete.

Results: All 12 young people showed significant improvements in carrying out everyday tasks between the baseline and treatment phases.

Conclusions: The NeuroPage system can be successfully used by children and adolescents with neurological deficits and can alleviate some of the everyday difficulties caused by their memory and planning difficulties.     

An Evaluation of a Behaviorally Based Social Skills Group for Individuals Diagnosed with Autism Spectrum Disorder

In this study we evaluated a social skills group which employed a progressive applied behavior analysis model for individuals diagnosed with autism spectrum disorder. A randomized control trial was utilized; eight participants were randomly assigned to a treatment group and seven participants were randomly assigned to a waitlist control group. The social skills group consisted of 32, 2 h sessions. Teachers implemented a variety of behaviorally based procedures. A blind evaluator measured participants’ behavior immediately prior to intervention, immediately following intervention, and during 16 and 32-week maintenance probes. Results of the study demonstrated that participants made significant improvements with their social behavior (p?<?.001) following intervention, and the results were maintained up to 32 weeks after intervention had concluded.     

A randomized, controlled trial of massage therapy as a treatment for migraine

Background: Migraine is a distressing disorder that is often triggered by stress and poor sleep. Only one randomized controlled trial (RCT) has assessed the effects of massage therapy on migraine experiences, which yielded some promising findings.Purpose: An RCT was designed to replicate and extend the earlier findings using a larger sample, additional stress-related indicators, and assessments past the final session to identify longer-term effects of massage therapy on stress and migraine experiences.Methods: Migraine sufferers (N = 47) who were randomly assigned to massage or control conditions completed daily assessments of migraine experiences and sleep patterns for 13 weeks. Massage participants attended weekly massage sessions during Weeks 5 to 10. State anxiety, heart rates, and salivary cortisol were assessed before and after the sessions. Perceived stress and coping efficacy were assessed at Weeks 4, 10, and 13.Results: Compared to control participants, massage participants exhibited greater improvements in migraine frequency and sleep quality during the intervention weeks and the 3 follow-up weeks. Trends for beneficial effects of massage therapy on perceived stress and coping efficacy were observed. During sessions, massage induced decreases in state anxiety, heart rate, and cortisol.Conclusions: The findings provide preliminary support for the utility of massage therapy as a nonpharmacologic treatment for individuals suffering from migraines. We thank the New Zealand College of Massage for their contribution to this project.     

Memory rehabilitation and brain training for surgical temporal lobe epilepsy patients: a preliminary report

The short term impact of a memory rehabilitation programme on verbal memory test performance and subjective ratings of memory in everyday life was assessed in healthy controls and left temporal lobe epilepsy (LTLE) surgical patients. The intervention involved training in the use of external and internal memory support strategies. Half of the sample in addition undertook computerised brain training exercises as homework. LTLE patients were seen either before surgery or 3-6 months after their operation. Improvements in verbal memory were observed in both groups. An effect of brain training was recorded but this did not occur in a consistent direction. Subjective ratings of memory indicated improvements that were significant for the LTLE group but not the controls. Positive changes in the memory outcome measures were associated with improvements in mood. Pre-operative memory rehabilitation was not associated with better outcomes than post-operative intervention. Further research is needed to explore the persistence of the changes observed and to explore if pre-operative rehabilitation offsets post-operative memory decline.     

Do memory aids help everyday memory? A controlled trial of a Memory Aids Service

There is a growing body of knowledge about the use of compensatory memory aids in memory rehabilitation, but relatively few controlled trials on how to train the use of such aids. This study investigated the effects of systematic training in the use of compensatory memory aids on everyday memory functioning within a Memory Aids Service. In a controlled clinical trial, a comparison was made between treatment participants and waiting list controls. Participants had everyday memory problems secondary to progressive or non-progressive neurological conditions. Following baseline assessment and goal setting, treatment participants underwent three training sessions, in which memory aids were matched to goals, across a six week period, with a follow-up assessment 12 weeks later. Outcome was measured by a goal attainment diary, neuropsychological test performance, psychosocial questionnaires and a problem solving inventory. There was a significant treatment effect of training on the goal attainment diary but only at 12 weeks follow-up. A post-hoc analysis indicated that treatment was effective for participants with a non-progressive condition but not for participants with a progressive condition. We conclude that a Memory Aids Service can be beneficial for patients with a non-progressive neurological condition, and make suggestions that might inform future applications of memory aids with those who have a progressive neurological disorder.     

Effect of activity reminiscence therapy as brain-activating rehabilitation for elderly people with and without dementia

Background: Preventing the progression of dementia is a widespread challenge. However, currently there is limited evidence supporting the effectiveness of dementia rehabilitation. Methods: We practiced activity reminiscence therapy (ART) as brain‐activating rehabilitation for both lucid and demented persons (n = 18) in a day‐service setting as well as in a group home. The ART sessions were conducted 1 hour every week for 12 weeks (intervention period). We compared the results of three cognitive tests (the Mini‐Mental State Examination, the Kana Pick‐out test and the ‘logical memory’ component of the Wechsler Memory Scale‐Revised) and four behavior and caregiver's burden scales (the Clinical Dementia Rating, the Multidimensional Observation Scale for Elderly Subjects, the Dementia Behavior Disturbance scale and the Zarit Caregiver Burden Interview) conducted during the control period with those taken during the intervention period. At the end of the intervention period, we interviewed the staff and families individually to assess whether the participants seemed to have changed after intervention and, if so, how. Results: In cognitive tests, only immediate and delayed recall of the Wechsler Memory Scale‐Revised showed significant improvement. None of the four behavior and caregiver's burden scales showed any significant changes after intervention. However, the interviews showed improvements in subjective aspects of communication, interaction and behavior. Conclusion: ART uses old‐style tools. The nostalgia brought about by using these familiar tools led to effective recall of experiences, in which the participants taught the staff how to use the tools, which were unfamiliar to the staff. Through this role‐reversal, they gained a sense of self‐worth and a desire to live. Due to the reconstructed relationship between participants and caregivers, we consider ART to be effective in maintaining and improving emotional functions, activities of daily living and memory. ART should be useful for both lucid and mildly demented persons as brain‐activating rehabilitation therapy.     

A randomized controlled trial of a manual-based psychosocial group intervention for young people with epilepsy [PIE]

We conducted an exploratory RCT to examine feasibility and preliminary efficacy for a manual-based psychosocial group intervention aimed at improving epilepsy knowledge, self-management skills, and quality of life in young people with epilepsy.MethodEighty-three participants (33:50 m/f; age range 12–17 years) were randomized to either the treatment or control group in seven tertiary paediatric neuroscience centres in the UK, using a wait-list control design. Participants were excluded if they reported suicidal ideation and/or scored above the cut off on mental health screening measures, or if they had a learning disability or other neurological disorder. The intervention consisted of six weekly 2-hour sessions using guided discussion, group exercises and role-plays facilitated by an epilepsy nurse and a clinical psychologist.ResultsAt three month follow up the treatment group (n = 40) was compared with a wait-list control group (n = 43) on a range of standardized measures. There was a significant increase in epilepsy knowledge in the treatment group (p = 0.02). Participants receiving the intervention were also significantly more confident in speaking to others about their epilepsy (p = 0.04). Quality of life measures did not show significant change. Participants reported the greatest value of attending the group was: Learning about their epilepsy (46%); Learning to cope with difficult feelings (29%); and Meeting others with epilepsy (22%). Caregiver and facilitator feedback was positive, and 92% of participants would recommend the group to others.ConclusionThis brief psychosocial group intervention was effective in increasing participants' knowledge of epilepsy and improved confidence in discussing their epilepsy with others. We discuss the qualitative feedback, feasibility, strengths and limitations of the PIE trial.
