Compensating for cognitive deficits following brain injury

Memory and Traumatic Brain Injury: Assessment and Management Practices of Speech-Language Pathologists

PURPOSE

Memory impairments are among the most commonly reported deficits and among the most frequent rehabilitation targets for individuals with traumatic brain injury (TBI). Memory and learning are also critical for rehabilitation success and broader long-term outcomes. Speech-language pathologists (SLPs) play a central role in memory management for individuals with TBI across the continuum of care. Yet, little is known about the current practice patterns of SLPs for post-TBI memory disorders. This study aims to examine the clinical management of memory disorders in adults with TBI by SLPs and identify opportunities to improve post-TBI memory outcomes.

METHOD

SLPs from across the continuum of care were recruited to complete an online survey. The survey assessed key practice areas specific to memory and memory disorders post-TBI, including education and training, knowledge and confidence, and assessment and treatment patterns.

RESULTS

Surveys from 155 SLPs were analyzed. Results revealed that TBI-specific training remains low in the field. Respondents varied in their practice patterns in assessing and treating memory disorders. Most SLPs do not appear to have access to appropriate standardized assessments to measure unique forms of memory. Respondents also reported a range of barriers and opportunities to advance memory outcomes following TBI and provided suggestions of areas in which they would like to see more basic and clinical research.

CONCLUSIONS

These findings establish a baseline of the current practices for clinical management of memory impairment in adults with TBI by SLPs. Improved opportunities for clinician training, the development of a single tool to assess multiple forms of memory, better access to existing memory assessments, and implementation of evidence-based interventions promise to lead to improved memory outcomes for individuals with TBI.

Game-supported cognitive strategy training for slowed information processing speed after acquired brain injury: study protocol for a randomised controlled trial

INTRODUCTION

Many individuals with acquired brain injury tend to experience problems with slowed information processing speed (IPS). A potentially beneficial and cost-effective supplement for cognitive rehabilitation of impaired IPS may be the implementation of serious gaming that focuses on compensatory learning as part of cognitive training. However, most digital platforms used during cognitive rehabilitation focus on restoring cognitive function and evidence for skill transfer from digital practice to everyday life is lacking. This study aims to investigate the efficacy of a game-supported cognitive strategy training. The training combines a well-validated time pressure management cognitive strategy training, targeting slowed IPS, with a novel game and a mobile application. The game-supported training focuses on the generalisation of strategy-use to untrained tasks in everyday life.

METHODS AND ANALYSIS

The study is designed as a randomised controlled trial in which the experimental group (Karman Line - Tempo module: an 8-week game-supported cognitive strategy training) will be compared with an active control group (CogniPlus training: an 8-week computerised cognitive function training). Data from 60 individuals with acquired brain injury (30 per group, ages between 16 and 75) will be collected at baseline (T0), post-treatment (T1) and at 3-month follow-up (T2). The primary outcome measure is an objective assessment of compensatory strategy use in an untrained experimental task. The secondary outcome is the attainment of trained and untrained treatment goals assessed by goal attainment scaling. Pre-training and post-training data will be analysed using a 2×2 repeated measure analysis of variance.

ETHICS AND DISSEMINATION

This study has been approved by the medical review ethics committee CMO Region Arnhem and Nijmegen (NL74818.091.20) and is registered in the Netherlands Trial Register. Research findings will be published in peer-reviewed journals and presented at conferences.

Using Single-Case Experimental Design and Patient-Reported Outcome Measures to Evaluate the Treatment of Cancer-Related Cognitive Impairment in Clinical Practice

Cancer-related cognitive impairment (CRCI) affects a large proportion of cancer survivors and has significant negative effects on survivor function and quality of life (QOL). Treatments for CRCI are being developed and evaluated. Memory and attention adaptation training (MAAT) is a cognitive-behavioral therapy (CBT) demonstrated to improve CRCI symptoms and QOL in previous research. The aim of this article is to describe a single-case experimental design (SCED) approach to evaluate interventions for CRCI in clinical practice with patient-reported outcome measures (PROs). We illustrate the use of contemporary SCED methods as a means of evaluating MAAT, or any CRCI treatment, once clinically deployed. With the anticipated growth of cancer survivorship and concurrent growth in the number of survivors with CRCI, the treatment implementation and evaluation methods described here can be one way to assess and continually improve CRCI rehabilitative services.

A cognitive rehabilitation program to improve hot and cool executive dysfunction in juvenile myoclonic epilepsy: Preliminary findings

OBJECTIVE

Executive and attentional deficits are often described in Juvenile Myoclonic Epilepsy (JME). We aimed to evaluate the short-term impact of rehabilitation developed for the most frequent cognitive deficits of persons with JME.

METHODS

Thirty-three patients entered this study which consisted of 12 individual sessions once a 60-minute week, divided into planning/organization, attention, and impulsivity. Twenty-seven patients finished the protocol, and all patients had pre-and-post evaluations from neuropsychological tests and self-rating questionnaires. Generalized Estimating Equations (GEE) inferential statistics were used to verify the protocol's effect, and a 95% confidence interval was adopted.

RESULTS

We found significant improvement in selective attention (TMT A [p < 0.01] and Stroop test 2 [p = 0.03]), inhibitory control (Stroop test 3 [p = 0.02], FAS [p < 0.01], CPT commissions [p < 0.01]), mental flexibility [WCST categories p < 0.01] and implicit decision making (IGT blocks A [p < 0.01], B [p = 0.02], C [p < 0.01] and D [p < 0.01]). All components of the Behavioral Rating Index of Executive Functions metacognition index and the general quotient had significant improvement (initiative [p ≤ 0.01], working memory [p ≤ 0.01], planning and organization [p ≤ 0.01], task monitor [p = 0.02] and organization of materials [p = 0.02]). Regarding the Behavioral Regulation Index, the "Emotional Control" was improved [p = 0.03]. The attentional component and general scores of the Adult Self-Report Scale for Adults also changed significantly [p ≤ 0.01].

SIGNIFICANCE

Executive function and attention had an improvement in objective and subjective tests. The context-dependent reactive mechanism of impulsivity improved in instruments based on the ecological evaluation. Our findings, though preliminary due to a lack of controls and practice effect corrections, support that cognitive rehabilitation may be a valuable resource to alleviate cognitive deficits in patients with JME.

Memory rehabilitation: restorative, specific knowledge acquisition, compensatory, and holistic approaches

Memory impairment following an acquired brain injury can negatively impact daily living and quality of life—but can be reduced by memory rehabilitation. Here, we review the literature on four approaches for memory rehabilitation and their associated strategies: (1) the restorative approach, aimed at a return to pre-morbid functioning, (2) the knowledge acquisition approach, involving training on specific information relevant to daily life, (3) the compensatory approach, targeted at improving daily functioning, and (4) the holistic approach, in which social, emotional, and behavioral deficits are addressed alongside cognitive consequences of acquired brain injury. Each memory rehabilitation approach includes specific strategies such as drill and practice (restorative), spaced retrieval (knowledge acquisition), memory aids (compensatory), or a combination of psychotherapy and cognitive strategies (holistic). Past research has demonstrated mixed support for the use of restorative strategies to improve memory function, whereas knowledge acquisition strategies show promising results on trained tasks but little generalization to untrained tasks and activities of daily living. Compensatory strategies remain widely used but require intensive training to be effectively employed. Finally, the holistic approach is becoming more widespread due to improvements in psychosocial wellbeing, yet there are considerable resource and cost requirements. Several factors can influence rehabilitation outcomes including metacognition and emotional disturbances. Considerations for future research to improve the applicability of strategies for memory rehabilitation include assessing memory impairment severity, examining memory needs in daily life, and exploring the long-term effects of memory rehabilitation.

Partner Contributions to Goal Pursuit: Findings From Repeated Daily Life Assessments With Older Couples

OBJECTIVES

This study focuses on the role of spouses for facilitating goal progress during a phase in life when individual resources for goal pursuit are particularly limited. Specifically, we examined the moderating role of relationship characteristics in old age for time-varying partner involvement-goal progress associations as couples engaged in their everyday lives. We also assessed time-varying associations between everyday goal progress, effectiveness of partner contributions, and spousal satisfaction with this contribution.

METHODS

We used multilevel modeling to analyze data from 118 couples (Mage = 70 years, SD = 5.9; 60-87 years, 50% women; 57% White). Both partners reported their personal goals and provided information on relationship satisfaction, conflict, and support. They also provided simultaneous ratings of everyday goal progress, effort, partner involvement as well as effectiveness of and satisfaction with partner contribution up to three times daily over 7 days.

RESULTS

In line with expectations, higher relationship satisfaction and support and lower conflict were associated with higher goal progress when the partner was involved in goal pursuit. Both effectiveness of and satisfaction with partner contributions were positively associated with everyday goal progress.

DISCUSSION

Whether partner involvement is beneficial for goal progress depends on characteristics of the relationship as well as what partners actually do in everyday life. This highlights the importance of considering both stable person characteristics as well as time-varying processes to capture the complexity of goal pursuit in older couples.

Literacy skill and intra-individual variability in eye-fixation durations during reading: Evidence from a diverse community-based adult sample

To understand the effects of literacy on fundamental processes involved in reading, we report a secondary data analysis examining individual differences in global eye-movement measures and first-pass eye-movement distributions in a diverse sample of community-dwelling adults aged 16 to 64. Participants (n = 80) completed an assessment battery probing verbal and non-verbal cognitive abilities and read simple two-sentence passages while their eye movements were recorded. Analyses were focused on characterising the effects of literacy skill on both global indices of eye-fixation distributions and distributional differences in the sensitivity to lexical features. Global reading measures showed that lower literate adults read more slowly on average. However, distributional analyses of fixation durations revealed that the first-pass fixation durations of adults with lower literacy skill were not slower in general (i.e., there was no shift in the fixation duration distribution among lower literate adults). Instead, lower literacy was associated with greater intra-individual variability in first-pass fixation durations, including an increased proportion of extremely long fixations, differentially skewing the distribution of both first-fixation and gaze durations. Exploratory repeated-measures quantile regression analyses of gaze duration revealed differentially greater influences of word length among lower literate readers and greater activation of phonological and orthographic neighbours among higher literate readers, particularly in the tail of the distribution. Collectively, these findings suggest that literacy skill in adulthood is associated with systematic differences in both global and lexically driven eye-movement control during reading.

Optimizing functional outcome endpoints for stroke recovery studies

Novel therapeutic intervention that aims to enhance the endogenous recovery potential of the brain during the subacute phase of stroke has produced promising results. The paradigm shift in treatment approaches presents new challenges to preclinical and clinical researchers alike, especially in the functional endpoints domain. Shortcomings of the "neuroprotection" era of stroke research are yet to be fully addressed. Proportional recovery observed in clinics, and potentially in animal models, requires a thorough reevaluation of the methods used to assess recovery. To this end, this review aims to give a detailed evaluation of functional outcome measures used in clinics and preclinical studies. Impairments observed in clinics and animal models will be discussed from a functional testing perspective. Approaches needed to bridge the gap between clinical and preclinical research, along with potential means to measure the moving target recovery, will be discussed. Concepts such as true recovery of function and compensation and methods that are suitable for distinguishing the two are examined. Often-neglected outcomes of stroke, such as emotional disturbances, are discussed to draw attention to the need for further research in this area.

Cognitive behavioral therapy for cancer-related cognitive dysfunction

PURPOSE OF REVIEW

To provide the reader with an overview of the cognitive-behavioral conceptualization of cancer-related cognitive dysfunction (CRCD) and how cognitive behavioral therapy (CBT) can play an important role in treatment.

RECENT FINDINGS

Recent findings show that Memory and Attention Adaptation Training (MAAT), a CBT developed to help cancer survivors develop adaptive skills to improve daily cognitive performance and emotional coping, may be an efficacious treatment of CRCD and can be delivered through videoconference technology to improve survivor access to care.

SUMMARY

The etiology of CRCD remains largely undetermined and likely is produced by multiple mechanisms. This can include neuronal death, microvascular damage, inflammatory processes, and psychological factors of perceptions of inadequate cognitive capacity to meet performance demands and related emotional distress. As a result, there are a variety of treatments currently being researched. More research with larger sample sizes, multiple clinicians and multiple sites are needed to confirm efficacy, but CBT approaches such as Memory and Attention Adaptation Training that address multiple psychological factors involved may offer a flexible nonpharmacological approach to CRCD that optimizes quality of life outcomes.

Crossmodal processing of emotions in alcohol-dependence and Korsakoff syndrome

INTRODUCTION

Decoding emotional information from faces and voices is crucial for efficient interpersonal communication. Emotional decoding deficits have been found in alcohol-dependence (ALC), particularly in crossmodal situations (with simultaneous stimulations from different modalities), but are still underexplored in Korsakoff syndrome (KS). The aim of this study is to determine whether the continuity hypothesis, postulating a gradual worsening of cognitive and brain impairments from ALC to KS, is valid for emotional crossmodal processing.

METHODS

Sixteen KS, 17 ALC and 19 matched healthy controls (CP) had to detect the emotion (anger or happiness) displayed by auditory, visual or crossmodal auditory-visual stimuli. Crossmodal stimuli were either emotionally congruent (leading to a facilitation effect, i.e. enhanced performance for crossmodal condition compared to unimodal ones) or incongruent (leading to an interference effect, i.e. decreased performance for crossmodal condition due to discordant information across modalities). Reaction times and accuracy were recorded.

RESULTS

Crossmodal integration for congruent information was dampened only in ALC, while both ALC and KS demonstrated, compared to CP, decreased performance for decoding emotional facial expressions in the incongruent condition.

CONCLUSIONS

The crossmodal integration appears impaired in ALC but preserved in KS. Both alcohol-related disorders present an increased interference effect. These results show the interest of more ecological designs, using crossmodal stimuli, to explore emotional decoding in alcohol-related disorders. They also suggest that the continuum hypothesis cannot be generalised to emotional decoding abilities.

The association between white-matter tract abnormalities, and neuropsychiatric and cognitive symptoms in retired professional football players with multiple concussions

Retired professional athletes, who have suffered repetitive concussions, report symptoms of depression, anxiety, and memory impairment over time. Moreover, recent imaging data suggest chronic white-matter tract deterioration in sport-related concussion. The aim of this study is to evaluate the impact of repetitive concussions in retired professional football players on white-matter tracts, and relate these changes to neuropsychological function. All subjects (18 retired professional football players and 17 healthy controls) underwent imaging, neuropsychological assessment, and reported on concussion-related symptoms. Whole brain tract-based spatial statistics analysis revealed increased axial diffusivity in the right hemisphere of retired players in the (1) superior longitudinal fasciculus (SLF), (2) corticospinal tract, and (3) anterior thalamic radiations, suggesting chronic axonal degeneration in these tracts. Moreover, retired players report significantly higher neuropsychiatric and cognitive symptoms than healthy controls, and worsening of these symptoms since their last concussion. Loss of integrity in the right SLF significantly correlated with participants' visual learning ability. In sum, these results suggest that repetitive concussions in retired professional football players are associated with focal white-matter tract abnormalities that could explain some of the neuropsychiatric symptoms and cognitive deficits experienced by these retired athletes.

Recovery after brain damage: Is there any indication for generalization between different cognitive functions?

INTRODUCTION

The question whether recovery in various cognitive functions is supported by one or two more fundamental functions (for instance, attentional or working memory functions) is a long-standing problem of cognitive rehabilitation. One possibility to answer this question is to analyze the recovery pattern in different cognitive domains and to see whether improvement in one domain is related to performance in another domain.

METHOD

Ninety-two inpatients with stroke or other brain lesions (Barthel Index >75) were included. Neuropsychological assessment was done at the beginning and the end of a rehabilitation stay. Cognitive performance was analyzed at test and at domain level using conceptually and statistically defined composite scores for attention, immediate and delayed memory, working memory, prospective memory, and word fluency. We used regression analysis to look for generalization between cognitive domains.

RESULTS

Effect sizes of improvement varied largely (from d = 0.18 in attention and d = 1.36 in episodic memory). Age, gender, and time since injury had no impact on recovery. Impaired patients showed significantly more improvement than nonimpaired patients. Regression analysis revealed no effect of initial performance in one cognitive domain on improvements in other cognitive domains.

CONCLUSION

Significant recovery in impaired cognitive domains can be expected during neuropsychological rehabilitation. It depends more or less exclusively on improvement in the specific functions itself, and there was no evidence for generalization between cognitive domains.

INCOG recommendations for management of cognition following traumatic brain injury, part IV: cognitive communication

INTRODUCTION

Cognitive-communication disorders are common in individuals with traumatic brain injury (TBI) and can have a major impact on long-term outcome. Guidelines for evidence-informed rehabilitation are needed, thus an international group of researchers and clinicians (known as INCOG) convened to develop recommendations for assessment and intervention.

METHODS

An expert panel met to select appropriate recommendations for assessment and treatment of cognitive-communication disorders based on available literature. To promote implementation, the team developed decision algorithms incorporating the recommendations, based on inclusion and exclusion criteria of published trials, and then prioritized recommendations for implementation and developed audit criteria to evaluate adherence to best practice recommendations.

RESULTS

Rehabilitation of individuals with cognitive-communication disorders should consider premorbid communication status; be individualized to the person's needs, goals, and skills; provide training in use of assistive technology where appropriate; include training of communication partners; and occur in context to minimize the need for generalization. Evidence supports treatment of social communication problems in a group format.

CONCLUSION

There is strong evidence for person-centered treatment of cognitive-communication disorders and use of instructional strategies such as errorless learning, metacognitive strategy training, and group treatment. Future studies should include tests of alternative service delivery models and development of participation-level outcome measures.

Self-Generated Strategic Behavior in an Ecological Shopping Task

OBJECTIVES. The use of cognitive strategies optimizes performance in complex everyday tasks such as shopping. This exploratory study examined the cognitive strategies people with traumatic brain injury (TBI) effectively use in an unstructured, real-world situation.

METHOD. A behavioral analysis of the self-generated strategic behaviors of 5 people with severe TBI using videotaped sessions of an ecological shopping task (Instrumental Activities of Daily Living Profile) was performed.

RESULTS. All participants used some form of cognitive strategy in an unstructured real-world shopping task, although the number, type, and degree of effectiveness of the strategies in leading to goal attainment varied. The most independent person used the largest number and a broader repertoire of self-generated strategies.

CONCLUSION. These results provide initial evidence that occupational therapists should examine the use of self-generated cognitive strategies in real-world contexts as a potential means of guiding therapy aimed at improving independence in everyday activities for people with TBI.

Evaluation of neuropsychological rehabilitation following severe traumatic brain injury: a case report

This case study presents the evaluation of traumatic brain injury rehabilitation for Jane, a 35-year-old woman who sustained a severe traumatic brain injury (TBI). On-going rehabilitation addressed difficulties within a structured neuro-rehabilitative therapeutic milieu and was holistically evaluated. Results showed improvement in mood and quality of life and at the compensatory level for cognition. At the impairment level, many of the affected areas of cognition remained at least below predicted pre-morbid levels. This supports the view that although TBI impairments may be permanent, structured neuro-rehabilitation can be effective through external and compensatory aids. Recording this holistically contributes to evidencing this.

A comparison of the content of memory rehabilitation groups for patients with neurological disabilities

The aim of the study was to compare the fidelity of manualised group memory rehabilitation programmes for participants with neurological disabilities. A sample of 11 neurological patients with memory problems, enrolled in a randomised controlled trial comparing compensation, restitution and self-help treatments, were observed during group sessions. Time-sampling was used to record the activity of the participants and the content of the discussion at one minute intervals. There was a significant difference between groups in the amount of time the group leader and participants spent talking (p < .001). Participants in the compensation and restitution groups spent significantly more time in memory rehabilitation discussion than participants in the self-help group (p < .001). There was also a significant difference between the amount of time spent discussing internal and external memory aids in the compensation and restitution groups (p < .001). These results support the fidelity of the interventions provided. This study also highlights the usefulness of time-sampling as a method to record the content and activity in rehabilitation groups.

Development of CBT for chemotherapy-related cognitive change: results of a waitlist control trial

OBJECTIVE

To evaluate the efficacy of a brief cognitive-behavioral therapy (CBT) that is being developed for management of cognitive dysfunction following chemotherapy among breast cancer survivors. Memory and Attention Adaptation Training (MAAT) is a brief CBT designed to improve the quality of life and function among cancer survivors with post-chemotherapy cognitive complaints.

METHODS

An initial, two-group (MAAT versus waitlist, no treatment control), randomized clinical trial (RCT) was conducted. Forty stage I and II female breast cancer survivors (mean age = 50; SD = 6.4) were randomized to conditions and assessed at baseline, post-treatment (8 weeks) and 2-month follow-up assessment points on measures of: (1) self-reported daily cognitive failures; (2) quality of life; and (3) neuropsychological performance. Participants were also assessed for satisfaction with MAAT.

RESULTS

With education and IQ as covariates, MAAT participants made significant improvements relative to controls on the spiritual well-being subscale of the quality of life measure and on verbal memory, but statistical significance was not achieved on self-report of daily cognitive complaints. However, moderate-to-large effect sizes were observed on these outcomes. Participants gave MAAT high satisfaction ratings.

CONCLUSIONS

Although this initial RCT is a small study, MAAT participants appear to improve on one measure of quality of life and verbal memory performance relative to no treatment controls and rate MAAT with high satisfaction. These data are encouraging and support the continued development and evaluation of MAAT efficacy.

Exploring the relation between learning style and cognitive impairment in patients with acquired brain injury

The way a patient prefers to approach or choose a learning situation represents the patient's learning style. The objective of this chart review study was to explore the relation between learning style and cognitive impairment in patients with acquired brain injury (ABI). We used data from files of 92 adult patients with ABI referred to inpatient rehabilitation, who completed the Adapted Learning Style Inventory (A-LSI) and at least one of the following neuropsychological tests: Trail Making Test, Rey Auditory Verbal Learning Test, WAIS-III Digit Span, Rey-Osterrieth Complex Figure Test-Copy, Stroop Color-Word Test, or the Brixton Spatial Anticipation Test. The A-LSI yielded the following distribution of learning styles: 4 doers, 48 observers, 2 deciders and 38 thinkers. No significant correlation coefficients were found between the neuropsychological tests and the A-LSI. Furthermore, Chi-square tests revealed no significant associations between learning style (observer, thinker) and cognitive impairment. The results of this exploratory study suggest that learning style and cognitive impairment are independent in patients with ABI.

Environmental effects in the performance of daily tasks in healthy adults

OBJECTIVE

We examined the effect of switching from a familiar to an unfamiliar setting on household task performance in healthy adults. We also examined the influence of the cognitive functions abstract reasoning and memory on the ability to adapt to different environments.

METHOD

Thirty healthy adults were observed in two different settings while they performed two daily tasks. We evaluated process skill abilities in task performance, time needed to perform each task, memory functioning, and abstract reasoning.

RESULTS

Performance of both tasks required significantly more time in the unfamiliar kitchen. Scores on process skill abilities were significantly lower in the unfamiliar kitchen. We found no associations between environmental effects and abstract reasoning or memory.

CONCLUSION

We found environmental effects on task performance in healthy adults. These findings have important implications for rehabilitation practice. Addressing facilitation of transfer of training effects to familiar environments is of great importance to rehabilitation programs.

The utility and benefits of clinical neuropsychology in Asia

Neuropsychological evaluation is the clinical practice of identifying and measuring impairments in mental functions in the context of a patient's mental strengths and preserved abilities for the purposes of diagnosis, rehabilitation planning, and long-term care. Best practice approaches to the medical management of neurodegenerative, neurological and psychiatric illness have lead to increasing demand for neuropsychological services. The simultaneous challenges of Asias' increasing adult and rapidly ageing population underscore the need for consideration of the role of neuropsychological services in day-to-day clinical practice. Here, we outline the clinical utility of neuropsychological assessment and indications for its use in general psychiatric practice.

Chapter 53: rehabilitation therapies

This chapter retraces the history and evolution of rehabilitative efforts by physicians and other health professionals to alleviate the symptoms and disabilities associated with neurological disorders. Rehabilitation therapies often provide interventions that go beyond traditional medical treatment aimed at treating impairments, and help those with neurological injuries and illness to re-establish themselves as productive and socially-integrated citizens by reducing their functional disabilities. The chapter considers the early history of practical treatments developed in Greek and Roman times, reviews the scattered attempts at treatment during the Middle Ages and Renaissance, examines the more recent development of specific rehabilitative techniques and disciplines in the 20th century, and also provides discussion of the contemporary application of empirically validated rehabilitation strategies and techniques that emphasize treatment efficacy. The evolution of medical and physical rehabilitation, occupational and vocational rehabilitation, aphasia and cognitive rehabilitation, are all discussed, with additional review of the influence of some of the military conflicts and wars in history that have stimulated the advancement of the clinical practice of rehabilitation. A critique of the benefits of comprehensive rehabilitative programs for traumatic brain injury and stroke is specifically included. The varied skepticism and optimism of treating neurological disorders throughout history is also highlighted.

A developmental framework for memory rehabilitation in children

Memory difficulties in adults with acquired brain injuries have been reported in the literature for some time. In recent years, the consequences of memory difficulties from acquired and neurodevelopmental disorders in children have also been investigated. Initial studies have suggested that, like adults, children can experience severe and specific memory deficits. However, there are important developmental differences, both in terms of the nature of cognitive difficulties experienced, and the subsequent consequences for learning, educational attainment and everyday living. Despite the advances made in developmental memory studies, as yet, there appears to be scant literature to guide effective rehabilitation specifically targeted at children. As a starting point, it may be appropriate to consider adaptation of adult rehabilitation strategies to address memory problems in children. This paper describes some of the common principles and practices of adult rehabilitation strategies and then considers the validity of such strategies against developmental models of the memory system and child's learning environment. In particular, four important areas are highlighted: the development of normal memory functions in children, the range of cognitive deficits that can occur in a developing brain, the interaction of memory deficits with other immature cognitive skills and the context of the psycho-social environment in which rehabilitation may take place.

Self-generated learning in people with multiple sclerosis: An extension of Chiaravalloti and DeLuca (2002)

Although memory impairment is common in people with multiple sclerosis (MS), few interventions have been tested to remediate forgetfulness in MS. Chiaravalloti and DeLuca (2002) examined the memory benefit of self-generated encoding over didactic presentation in people with MS and a control group. They found that self-generated encoding enhanced memory of MS patients and a control group alike. The present study extended this finding by examining self-generated encoding in memory-impaired MS patients as well. A control group and MS patients with and without memory impairment learned word-pairs that were either self-generated or didactically presented. All groups remembered more self-generated words than those that were read aloud, and severity of memory impairment failed to moderate this memory benefit. Implications of these findings for cognitive rehabilitation and the nature of memory impairment in MS are discussed.

Cognitive-behavioral management of chemotherapy-related cognitive change

Adjuvant chemotherapy can produce mild cognitive decline among breast cancer survivors which adversely effects function and quality of life. However, no treatment to date has been proposed or developed for this problem despite large numbers of cancer patients who report post-treatment memory dysfunction. This paper presents data from a single arm pilot study of a brief cognitive-behavioral treatment aimed at helping breast cancer survivors manage cognitive dysfunction associated with adjuvant chemotherapy (Memory and Attention Adaptation Training; MAAT). Participants were twenty-nine women who were an average of 8 years post-chemotherapy for stage I and II breast cancer. All had reported complaints regarding memory and attention. Improvements in self-report of cognitive function, quality of life and standard neuropsychological test performance were observed at post-treatment, 2-month and 6-month follow-up. Participants also reported high treatment satisfaction and rated MAAT as helpful in improving ability to compensate for memory problems. Given these results, the treatment appears to be a feasible and practical cognitive-behavioral program that warrants continued evaluation among cancer survivors who experience persistent cognitive dysfunction.

Pre- and post-encephalitic neuropsychological profile of a 7-year-old girl

Our understanding of the neuropsychological effects of encephalitis has largely come from studies in which the level of premorbid functioning is estimated. Moreover, data on the neuropsychological effects of encephalitogenic pathogens other than the herpes simplex virus (HSV) are scant. We present the case of a 7-year-old girl who had intellectual and language assessment seven months prior to the onset of non-HSV encephalitis (possible aetiology: Mycoplasma pneumoniae), and again post-encephalitis. MRI post-illness demonstrated basal frontal, temporal and (limited) parietal damage. Details of speech, psychological and neuropsychological assessments were also documented. Pervasive changes were apparent in the domains of personality, behaviour, emotionality, attention, executive function, speech, language and memory. The patient's profile appears to differ most from that seen following typical HSV encephalitis with respect to marked executive and attentional difficulties. Her deficits appear to reflect both her acute basal brain injury and more diffuse insult, probably caused by postinfectious encephalitis.

Implications of basic science research for brain injury rehabilitation: a focus on intact learning mechanisms

Within a theoretical framework for rehabilitation that distinguishes between automatic and controlled processes, this article reviews basic science research and addresses the following issues: What cognitive abilities remain relatively intact after severe traumatic brain injury, and how can we incorporate intact skills into rehabilitative techniques? The reviewed research indicates that individuals with severe traumatic brain injury (a) generally perform similar to controls on cognitive tasks (or task components) that require automatic and implicit processes as opposed to consciously controlled processes; (b) can learn through implicit learning mechanisms; and (c) can acquire and use automatic processes in complex, cognitive task performance.

Self-generated learning in people with multiple sclerosis

Memory impairment is among the most common cognitive deficits in people with multiple sclerosis (MS). To remediate this problem, recent research has evaluated the benefits of self-generated encoding. These nascent investigations reveal that people with MS who have mild memory impairment demonstrate a significant memory benefit from self-generated encoding compared with didactic learning. To extend prior research, the present experiment included MS patients with moderate-severe, rather than just mild, memory impairment. Additionally, the experiment evaluated whether self-generated encoding improves memory for activities of daily living instead of abstract words. Specifically, the experiment determined whether self-generated encoding enhanced memory for names, appointments, and object locations. In agreement with and extending prior research, MS patients remembered more information if it was self-generated rather than didactically presented, and this finding occurred despite moderate-severe memory impairment. Furthermore, compared with didactic encoding, self-generation enhanced recall of activities of daily living. Implications of these findings for cognitive rehabilitation and the nature of memory impairment in MS are discussed.

Applied psychophysiology, clinical biofeedback, and rehabilitation neuropsychology: a case study—mild traumatic brain injury and post-traumatic stress disorder

This article presents a case study of a 39-year-old European American married woman with a history of child and adolescent incest,marital rape, and physical abuse from her husband for more than 10 years. She was referred to a pain clinic for treatment of headaches and Tourette's syndrome. The client was evaluated with the Ackerman-Banks Neuropsychological Rehabilitation Battery to identify neuropsychological strengths and weaknesses. The Vulnerability to Stress Audit was used to identify life events that were positively and negatively influencing her life. The client was treated for mild traumatic brain injury, post-traumatic stress disorder,cognitive difficulties, impulsivity, confabulation, low frustration tolerance, and inability to evaluate and make decisions about socially appropriate behaviors. Treatment involved traditional psychotherapy, hypnosis, cognitive rehabilitation, biofeedback training, electromyography, finger temperature, and blood pressure.

Developing and implementing lifestyle management programs© with people with multiple sclerosis

SUMMARY This paper describes the development and use of Lifestyle Management Programs© (LMPs) by occupational therapists at the Multiple Sclerosis Society of New South Wales, Australia. A case study is used to demonstrate how the program is applied in an individual situation. LMPs are used with people with MS, or their support people, to enable management of the impact of fluctuating and interactive physical, sensory and cognitive symptoms. LMPs are flexible and adaptable systems, allowing integration of information and strategies for managing symptoms. LMPs assist clients to sustain meaningful activities and life roles. Subjective client feedback supports the effectiveness of the programs in meeting specific individual goals. Formal outcome measures are being explored.

Grundlagen und Empirie der Neuropsychologischen Therapie: Neuropsychotherapie oder Hirnjogging?

Zusammenfassung: Dieser Beitrag beschäftigt sich mit dem theoretischen Fundament und den empirischen Grundlagen neuropsychologischer Interventionen. Nach einem kurzen historischen Rückblick werden die konzeptionellen Grundlagen einer neuropsychologischen Behandlung dargestellt und erläutert. Neuropsychologische Interventionen werden drei Therapiesäulen zugeordnet: Restitution, Kompensation und integrierten Verfahren. Restitution bezieht sich auf Maßnahmen, mit denen gestörte neuronale Systeme wieder reaktiviert werden sollen. Kompensation beinhaltet den aktiven oder passiven Ausgleich von Funktionsdefiziten durch vorhandene Fähigkeiten. Hierzu zählt nicht nur das Lernen neuer Strategien und der Einsatz von Hilfsmitteln, sondern auch die Veränderung von Erwartungen, Lebenszielen und andere kognitive Anpassungen. Integrierte Verfahren stellen Verfahren (z. B. operante Techniken) anderer Psychotherapierichtungen dar, die bei einer neuropsychologischen Behandlung Anwendung finden können und auf die Bedürfnisse von Patienten mit organisch bedingten psychischen Störungen zugeschnitten sind. Die in dem Beitrag referierten Studien unterstreichen die Bedeutung der drei postulierten Therapiesäulen.

Use of a portable voice organizer to remember therapy goals in traumatic brain injury rehabilitation: a within-subjects trial

OBJECTIVE

To test the efficacy of a portable voice organizer in helping people with traumatic brain injury (TBI) to recall therapy goals and plans discussed with their clinical case managers.

DESIGN

Prospective within-subjects trial, in which individualized therapy goals were randomly assigned to intervention or no intervention.

SETTING

Comprehensive postacute TBI rehabilitation program.

PARTICIPANTS

Ten people with moderate to severe TBI enrolled from 3 months to 18 years after injury.

OUTCOME MEASURE

Memory for therapy goals. Clinicians generated statements describing six current therapy goals, half of which were randomly assigned to be recorded on a voice organizer during the next case management session. Participants selected three times per day to listen to the recorded goals, prompted by an alarm. One-week recall was tested using both free- and cued-recall formats.

RESULTS

Recorded goals were recalled better than unrecorded goals and appeared to be associated with better awareness or follow-through with therapy objectives.

CONCLUSION

Portable electronic devices have the potential to assist with treatment areas beyond tasks involving prospective memory.

Historical review of computer-assisted cognitive retraining

OBJECTIVES

This article details the introduction and development of the use of microcomputers as adjuncts to traditional cognitive rehabilitation of persons with acquired brain injury.

SUMMARY

The initial application of video games as therapeutic recreation in the late 1970s was soon followed in the early 1980s by the use of the first personal computers and available educational software. By the mid-1980s, both the IBM PC and Macintosh platforms were established, along with simplified programming languages that allowed individuals without extensive technical expertise to develop their own software. Several rehabilitation clinicians began to produce and market specially written cognitive retraining software for one or the other platform. Their work was detailed and reviewed, as was recently released software from commercial sources. The latter discussion included the latest developments in the rehabilitation applications of personal digital assistants and related organizing, reminding, and dictation devices. A summary of research on the general and specific efficacy of computer-assisted cognitive retraining illustrated the lingering controversy and skepticism that have been associated with this field since its inception.

CONCLUSIONS

Computer-assisted cognitive retraining (CACR) can be an effective adjunct to a comprehensive program of cognitive rehabilitation. Training needs to be focused, structured, monitored, and as ecologically relevant as possible for optimum effect. Transfer or training or generalizability of skills remains a key issue in the field and should be considered the key criterion in evaluating whether to initiate or continue CACR.

Neurocognitive impairment associated with alcohol use disorders: implications for treatment

Between 50% and 80% of individuals with alcohol use disorders experience mild to severe neurocognitive impairment. There is a strong clinical rationale that neurocognitive impairment is an important source of individual difference affecting many aspects of addiction treatment, but empirical tests of the direct influence of impairment on treatment outcome have yielded weak and inconsistent results. The authors address the schism between applied-theoretical perspectives and research evidence by suggesting alternative conceptual models of the relationship between neurocognitive impairment and addiction treatment outcome. Methods to promote neurocognitive recovery and ways in which addiction treatments may be modified to improve psychosocial adaptation are suggested. Specific suggestions for future research that may help clarify the complex relations between neurocognitive impairment and addiction treatment are outlined.
