Feasibility of modifying the hospital environment to reduce the length of amnesia after traumatic brain injury: a pilot randomized controlled trial.

BACKGROUND: Reorientation programmes have been an important component of neurotrauma rehabilitation for adults who suffer from post-traumatic amnesia (PTA) after traumatic brain injury (TBI); however, research testing the efficacy of acute programmes is limited. OBJECTIVE: This study aimed to determine if it is feasible to provide a standardized environmental reorientation programme to adults suffering from PTA after TBI in an acute care hospital setting, and whether it is likely to be beneficial. METHODS: We conducted a randomized controlled trial with concealed allocation and intention-to-treat analysis. A total of 40 participants suffering from PTA after TBI were included. The control group received usual care; the experimental group received usual care plus a standardized orientation programme inclusive of environmental cues. The primary outcome measure was time to emergence from PTA measured by the Westmead PTA Scale, assessed daily from hospital admission or on regaining consciousness. RESULTS: Adherence to the orientation programme was high, and there were no study-related adverse responses to the environmental orientation programme. Although there were no statistically significant between-group differences in time to emergence, the median time to emergence was shorter for those who received the standardized reorientation programme (9.0 (6.4-11.6) versus 13.0 (4.5-21.5) days). Multivariate analysis showed that the Glasgow Coma Scale (GCS) at scene (P = 0.041) and GCS at arrival at hospital (P = 0.0001) were significant factors contributing to the longer length of PTA. CONCLUSION: Providing an orientation programme in acute care is feasible for adults suffering from PTA after TBI. A future efficacy trial would require 216 participants to detect a between-group difference of 5 days with an alpha of 0.05 and a power of 80%.

Factors Affecting Participation in Physical Therapy During Posttraumatic Amnesia.

OBJECTIVES: To examine the effect of agitation, cognitive impairment, fatigue, and pain on physical therapy participation and outcomes during posttraumatic amnesia (PTA) after traumatic brain injury (TBI). DESIGN: Prospective longitudinal study. SETTING: Inpatient rehabilitation hospital. PARTICIPANTS: Participants (N=77) with moderate-to-severe TBI who were deemed to be experiencing PTA using the Westmead Post-Traumatic Amnesia Scale. INTERVENTIONS: Not applicable. MAIN OUTCOME MEASURES: The Pittsburgh Rehabilitation Participation Scale and time in therapy (min) were recorded twice daily after routine physical therapy sessions during PTA. The FIM-motor (select items related to physical therapy) score rated on admission and after emergence from PTA was used to calculate FIM-motor change. RESULTS: Agitation was associated with lower participation in therapy. The presence of agitation and pain both predicted lower FIM-motor change at emergence from PTA. Higher levels of cognitive impairment and fatigue were also associated with lower participation and less time in therapy. CONCLUSIONS: The presence of agitation, fatigue, pain, and cognitive impairment impede rehabilitation success during PTA. This study strengthens the case for implementing environmental and behavioral recommendations, such as conducting therapy earlier in the day within a familiar space (ie, on the ward) and tailoring session duration to patient needs. This is with the aim of minimizing fatigue, agitation, and pain, while promoting cognitive recovery and arousal during PTA to maximize physical gains. Further research is warranted to examine the factors associated with rehabilitation success across other therapeutic disciplines.

Memory Compensation Strategies in Older People with Mild Cognitive Impairment.

OBJECTIVES: With the rapid growth of the older population worldwide, understanding how older adults with mild cognitive impairment (MCI) use memory strategies to mitigate cognitive decline is important. This study investigates differences between amnestic and nonamnestic MCI subtypes in memory strategy use in daily life, and how factors associated with cognition, general health, and psychological well-being might relate to strategy use. METHODS: One hundred forty-eight participants with MCI (mean age = 67.9 years, SD = 8.9) completed comprehensive neuropsychological, medical, and psychological assessments, and the self-report 'Memory Compensation Questionnaire'. Correlational and linear regression analyses were used to explore relationships between memory strategy use and cognition, general health, and psychological well-being. RESULTS: Memory strategy use does not differ between MCI subtypes (p > .007) despite higher subjective everyday memory complaints in those with amnestic MCI (p = .03). The most marked finding showed that increased reliance-type strategy use was significantly correlated with more subjective memory complaints and poorer verbal learning and memory (p < .01) in individuals with MCI. Moreover, fewer subjective memory complaints and better working memory significantly predicted (p < .05) less reliance strategy use, respectively, accounting for 10.6% and 5.3% of the variance in the model. CONCLUSIONS: In general, the type of strategy use in older adults with MCI is related to cognitive functioning. By examining an individual's profile of cognitive dysfunction, a clinician can provide more personalized clinical recommendations regarding strategy use to individuals with MCI, with the aim of maintaining their day-to-day functioning and self-efficacy in daily life.

Long-term effects of a memory group intervention reported by older adults.

The aim of this study was to examine older adults' experiences of change following a group memory intervention, the La Trobe and Caulfield Hospital (LaTCH) Memory Group programme. Semi-structured qualitative interviews were conducted with 30 individuals. Participants were healthy older adults and older adults with amnestic mild cognitive impairment (MCI) who had participated in the memory group five years previously. Transcripts were analysed for emergent themes in a workshop, using the Most Significant Change technique. The focus group derived four major themes relating to participants' experiences of change. Particularly noteworthy were themes describing a process of acceptance and normalising of memory difficulties in older age, as well as enhancement of coping and self-efficacy. The results highlight the importance of group support for older adults with and without objective memory impairment. Memory groups may use the group format to full advantage by (a) enhancing participants' experiences of universality to alleviate distress and promote coping, and (b) developing group norms to promote positive ageing, encompassing enhanced acceptance and self-efficacy.

Occupational performance and multisensory stimulation during post-traumatic amnesia: An observational and randomized controlled trial protocol.

BACKGROUND.: Occupational performance (OP) and interventions during post-traumatic amnesia (PTA) following traumatic brain injury are poorly understood. PURPOSE.: This study aims to describe a study protocol to (a) track person factors of OP throughout PTA and (b) assess the feasibility of a randomized controlled trial (RCT) protocol comparing an occupation-based multisensory stimulation and environmental enrichment intervention with usual care during PTA. METHOD.: A prospective observational study will be conducted with an embedded Phase II RCT with 30 participants in PTA. Participants will be randomly assigned to group and regularly assessed on PTA and OP measures. Feasibility aspects will be recorded in a logbook. All measures will be repeated at PTA resolution and 1 month later, with a follow-up questionnaire completed at 6 months postinjury. FINDINGS.: Observational data will be analyzed using correlations. Feasibility will be examined descriptively, and group comparisons will be conducted to determine effect size. IMPLICATIONS.: Results will provide a broader understanding of OP during PTA and inform future trials.

Activities of daily living retraining and goal attainment during posttraumatic amnesia.

It is uncertain whether therapy delivered during posttraumatic amnesia (PTA) following traumatic brain injury can be effective due to risk of agitation and poor learning capacity. This study used goal attainment scaling (GAS) to assess gains in activities of daily living (ADL) retraining during PTA. Occupational therapists' perspectives on goal setting and therapy delivery were also explored qualitatively. Forty-nine rehabilitation inpatients were provided with manualised ADL retraining following errorless and procedural learning principles during PTA. From 104 GAS goals, 90% were achieved at PTA emergence. GAS T-scores changed significantly (p < .001) from baseline (M = 26.94, SD = 4.90) to post-intervention (M = 61.44, SD = 11.45). Mean post-intervention T-scores correlated significantly (p < .001) with change in Functional Independence Measure scores. The four therapists reported that GAS was unfamiliar and time-consuming initially, although it aided goal-directed therapy and measurement of patient performance. Application of manualised skill retraining using errorless and procedural learning techniques was described as novel and challenging, but providing valuable structure. The intervention reportedly promoted therapeutic alliance, skill-building and meaningful time-use without elevating agitation, but fatigue impeded therapy. Overall, GAS captured positive individual change following ADL retraining during PTA and therapists indicated that the intervention and use of GAS was generally beneficial and feasible within clinical practice.

Economic Evaluation of Activities of Daily Living Retraining During Posttraumatic Amnesia for Inpatient Rehabilitation Following Severe Traumatic Brain Injury.

OBJECTIVE: To evaluate the cost-effectiveness of structured activities of daily living (ADL) retraining during posttraumatic amnesia (PTA) plus treatment as usual (TAU) vs TAU alone for inpatient rehabilitation following severe traumatic brain injury (TBI). DESIGN: Trial-based economic evaluation from a health-system perspective. SETTING: Inpatient rehabilitation center. PARTICIPANTS: Participants (N=104) admitted to rehabilitation and in PTA for >7 days following severe TBI. INTERVENTIONS: Structured ADL retraining during PTA plus TAU vs TAU alone. Structured ADL retraining was manualized to minimize the risk of agitation and maximize functional improvement, following principles of errorless and procedural learning and targeting individualized therapy goals. TAU included physiotherapy and/or speech therapy during PTA plus ADL retraining after PTA emergence. MAIN OUTCOME MEASURES: FIM total scores at baseline, PTA emergence, hospital discharge, or final follow-up (2mo postdischarge) where FIM total scores were calculated as the sum of 5 FIM motor self-care items and a FIM meal-preparation item. RESULTS: Structured ADL retraining during PTA significantly increased functional independence at PTA emergence (mean difference: 4.90, SE: 1.4, 95% confidence interval [CI]: 1.5, 8.3) and hospital discharge (mean difference: 5.22, SE: 1.4, 95% CI: 1.8, 8.7). Even in our most pessimistic scenario, structured ADL retraining was cost-saving as compared to TAU (mean: -$7762; 95% CI: -$8105, -$7419). Together, these results imply that structured ADL retraining dominates (less costly but no less effective) TAU when effectiveness is evaluated at PTA emergence and hospital discharge. CONCLUSIONS: Structured ADL retraining during PTA yields net cost-savings to the health system and offers a cost-effective means of increasing functional independence at PTA emergence and hospital discharge.

[Memory Rehabilitation for Amnesic with Acquired Brain Injury].

Two theoretical frameworks based on cognitive rehabilitation principles are recommended for the rehabilitation of memory impaired individuals. The first is improving memory function by the remediation of brain plasticity, known as remediation-oriented rehabilitation, and second is the compensation of memory function through the use of external memory aids, environmental modifications, and intact cognitive functions to overcome limitations in daily life. In rehabilitation of episodic memory impaired individuals, it has been recognized that the effortful active retrieval technique is more effective than the memorization technique. In contrast, the errorless learning technique with high-effort conditions and the active participation of patients has been recognized to be particularly effective in directly improving impaired episodic memory systems. More recently, another mnemonic strategy called the spaced retrieval technique has gained support. The theoretical components of spaced retrieval consist of classical conditioning, priming, the spacing effect, and errorless learning by taking advantage of the implicit memory system, which is preserved in many people with memory loss.

Hand gestures support word learning in patients with hippocampal amnesia.

Co-speech hand gesture facilitates learning and memory, yet the cognitive and neural mechanisms supporting this remain unclear. One possibility is that motor information in gesture may engage procedural memory representations. Alternatively, iconic information from gesture may contribute to declarative memory representations mediated by the hippocampus. To investigate these alternatives, we examined gesture's effects on word learning in patients with hippocampal damage and declarative memory impairment, with intact procedural memory, and in healthy and in brain-damaged comparison groups. Participants learned novel label-object pairings while producing gesture, observing gesture, or observing without gesture. After a delay, recall and object identification were assessed. Unsurprisingly, amnesic patients were unable to recall the labels at test. However, they correctly identified objects at above chance levels, but only if they produced a gesture at encoding. Comparison groups performed well above chance at both recall and object identification regardless of gesture. These findings suggest that gesture production may support word learning by engaging nondeclarative (procedural) memory.

Agitated Behavior and Activities of Daily Living Retraining During Posttraumatic Amnesia.

BACKGROUND: Patients in posttraumatic amnesia (PTA) may receive limited rehabilitation due to the risk of overstimulation and agitation. This assumption has not been tested. OBJECTIVE: To examine the relationship between agitated behavior and participation in therapy for retraining of activities of daily living (ADL) while in PTA. SETTING: Inpatient rehabilitation center. PARTICIPANTS: A total of 104 participants with severe traumatic brain injury, admitted to rehabilitation, in PTA of more than 7 days. INTERVENTION: ADL retraining during PTA followed errorless and procedural learning principles. DESIGN: Group comparison and regression modeling of patient agitation data from a randomized controlled trial comparing ADL retraining in PTA (treatment) versus no ADL retraining in PTA (treatment as usual, TAU). OUTCOME MEASURES: Agitation using the Agitated Behavior Scale. Therapy participation measured in minutes and missed sessions. RESULTS: There were no group differences in agitated behavior (average scores, peak scores, or number of clinically agitated days) between the treatment and TAU groups. For treated patients, there was no significant relationship between agitation and therapy participation (therapy minutes or missed ADL treatment sessions). CONCLUSIONS: This study demonstrated that agitation is not increased by delivery of structured ADL retraining during PTA and agitation did not limit therapy participation. This supports the consideration of active therapy during PTA.

Efficacy of Activities of Daily Living Retraining During Posttraumatic Amnesia: A Randomized Controlled Trial.

OBJECTIVE: To assess the efficacy of activities of daily living (ADL) retraining during posttraumatic amnesia (PTA) compared with ADL retraining commencing after emergence from PTA. DESIGN: Randomized controlled trial. SETTING: Inpatient rehabilitation center. PARTICIPANTS: Participants with severe TBI (N=104), admitted to rehabilitation and remaining in PTA for >7 days, were randomized to receive either treatment as usual (TAU) with daily ADL retraining (treatment), or TAU alone (physiotherapy and/or necessary speech therapy) during PTA. INTERVENTIONS: ADL retraining was manualized, followed errorless and procedural learning principles, and included individualized goals. Both groups received occupational therapy as usual after PTA. MAIN OUTCOME MEASURES: Primary outcome was the FIM completed at admission, PTA emergence, discharge, and 2-month follow-up. Secondary outcomes included length of rehabilitation inpatient stay, PTA duration, Agitated Behavior Scale scores, and Community Integration Questionnaire (CIQ) scores at follow-up. Groups did not significantly differ in baseline characteristics. RESULTS: On the primary outcome, FIM total change, random effects regression revealed a significant interaction of group and time (P<.01). The treatment group had greater improvement in FIM scores from baseline to PTA emergence, which was maintained at discharge, but not at follow-up. Twenty-seven percent more of the treatment group reliably changed on FIM scores at PTA emergence. Group differences in length of stay, PTA duration, agitation, and CIQ scores were not significant; however, TAU trended toward longer length of stay and PTA duration. CONCLUSIONS: Individuals in PTA can benefit from skill retraining.

Cognitive and Neural Effects of Vision-Based Speed-of-Processing Training in Older Adults with Amnestic Mild Cognitive Impairment: A Pilot Study.

OBJECTIVES: To examine the cognitive and neural effects of vision-based speed-of-processing (VSOP) training in older adults with amnestic mild cognitive impairment (aMCI) and contrast those effects with an active control (mental leisure activities (MLA)). DESIGN: Randomized single-blind controlled pilot trial. SETTING: Academic medical center. PARTICIPANTS: Individuals with aMCI (N = 21). INTERVENTION: Six-week computerized VSOP training. MEASUREMENTS: Multiple cognitive processing measures, instrumental activities of daily living (IADLs), and two resting state neural networks regulating cognitive processing: central executive network (CEN) and default mode network (DMN). RESULTS: VSOP training led to significantly greater improvements in trained (processing speed and attention: F1,19  = 6.61, partial η(2)  = 0.26, P = .02) and untrained (working memory: F1,19  = 7.33, partial η(2)  = 0.28, P = .01; IADLs: F1,19  = 5.16, partial η(2)  = 0.21, P = .03) cognitive domains than MLA and protective maintenance in DMN (F1, 9  = 14.63, partial η(2)  = 0.62, P = .004). VSOP training, but not MLA, resulted in a significant improvement in CEN connectivity (Z = -2.37, P = .02). CONCLUSION: Target and transfer effects of VSOP training were identified, and links between VSOP training and two neural networks associated with aMCI were found. These findings highlight the potential of VSOP training to slow cognitive decline in individuals with aMCI. Further delineation of mechanisms underlying VSOP-induced plasticity is necessary to understand in which populations and under what conditions such training may be most effective.

Predictors of Recovery From Posttraumatic Amnesia.

This study examined the predictive value of variables known early in the course of posttraumatic amnesia (PTA) on length of PTA and functional outcome of acute rehabilitation. Forty patients with traumatic brain injury who had PTA at admission for acute inpatient rehabilitation were included (29 men and 11 women; aged 18-91 years). This article presents the characteristics of the patients who came out of PTA and those who did not emerge during the acute inpatient rehabilitation stay. These data suggest that the location of the lesion (specifically, parietal lobe lesions) and initial cognitive scores are helpful in prognosticating patient trajectories.

Source Memory Rehabilitation: A Review Toward Recommendations for Setting Up a Strategy Training Aimed at the "What, Where, and When" of Episodic Retrieval.

Source memory is a core component of episodic recall as it allows for the reconstruction of contextual details characterizing the acquisition of episodic events. Unlike episodic memory, little is known about source memory rehabilitation. Our review addresses this issue by emphasizing several strategies as useful tools in source memory rehabilitation programs. Four main strategies are likely to improve source recall in amnesic patients-namely, (a) contextual cueing, (b) unitization, (c) errorless learning, and (d) executive function programs. The rationale behind our suggestion is that: (a) reinstating contextual cues during retrieval can serve as retrieval cues and enhance source memory; (b) unitization as an encoding process allows for the integration of several pieces of contextual information into a new single entity; (c) errorless learning may prevent patients from making errors during source learning; and (d) as source memory deteriorations have been classically attributed to executive dysfunction, the rehabilitation of the latter ability is likely to maintain the former ability. Besides these four strategies, our review suggests several additional rehabilitation techniques such as the vanishing cues and spaced retrieval methods. Another additional strategy is the use of electronic devices. By gathering these strategies, our review provides a helpful guideline for clinicians dealing with source memory impairments. Our review further highlights the lack of randomized and controlled studies in the field of source memory rehabilitation.

Accuracy of self-reported length of coma and posttraumatic amnesia in persons with medically verified traumatic brain injury.

OBJECTIVE: To determine the accuracy of self-reported length of coma and posttraumatic amnesia (PTA) in persons with medically verified traumatic brain injury (TBI) and to investigate factors that affect self-report of length of coma and PTA duration. DESIGN: Prospective cohort study. SETTING: Specialized rehabilitation center with inpatient and outpatient programs. PARTICIPANTS: Persons (N=242) with medically verified TBI who were identified from a registry of persons who had previously participated in TBI-related research. INTERVENTION: Not applicable. MAIN OUTCOME MEASURES: Self-reported length of coma and self-reported PTA duration. RESULTS: Review of medical records revealed that the mean medically documented length of coma and PTA duration was 6.9±12 and 19.2±22 days, respectively, and the mean self-reported length of coma and PTA duration was 16.7±22 and 106±194 days, respectively. The average discrepancy between self-report and medical record for length of coma and PTA duration was 8.2±21 and 64±176 days, respectively. Multivariable regression models revealed that time since injury, performance on cognitive tests, and medical record values were associated with self-reported values for both length of coma and PTA duration. CONCLUSIONS: In this investigation, persons with medically verified TBI showed poor accuracy in their self-report of length of coma and PTA duration. Discrepancies were large enough to affect injury severity classification. Caution should be exercised when considering self-report of length of coma and PTA duration.

Repetition-lag training to improve recollection memory in older people with amnestic mild cognitive impairment. A randomized controlled trial.

The results of a randomized controlled trial of repetition-lag training in older adults with amnestic mild cognitive impairment (aMCI) are reported. A modified repetition-lag training procedure with extended encoding time and strategy choice was used. The training required discriminating studied words from non-studied lures that were repeated at varying intervals during the test phase. Participants were assessed pre/post using untrained measures of cognition and self-report questionnaires. Primary outcome measures were recall of unrelated word pairs both immediately following presentation and following a delay. Secondary outcomes were a measure of attention, cognitive flexibility, and visual working memory. Participants were also asked to report on the frequency of cognitive failures and mood before and after training. Participants (N = 31) were randomized into either the treatment or a no-contact control group and attended the clinic twice per week over a four week period. Twenty-four participants completed the study (twelve in each group). Results indicated that the training group improved at recalling unrelated word pairs after a delay. There were no significant effects of training on other outcomes, self-reported cognitive failures or mood. The results are discussed along with suggestions for future research.

Long-term spacing effect benefits in developmental amnesia: case experiments in rehabilitation.

OBJECTIVE: The spacing effect describes the typical finding that repeated items are remembered best when additional items are introduced between each repetition than when the repetitions occur in immediate succession. In this study, we investigated the nature and limits of the spacing effect in the developmental amnesic case H.C. METHOD: In Experiment 1, we compared the performance of H.C. to that of controls on a short-term, free recall, verbal learning spacing paradigm while controlling for retention interval (timing of item review and recall). In Experiment 2, we compared the performance of H.C. to that of controls on a multiday, cued recall, verbal learning spacing paradigm, in which memory was assessed after 1 week. RESULTS: In both experiments, H.C. demonstrated a spacing effect comparable to the effect exhibited by controls. In Experiment 1, her final recall memory for long-lag (spaced) items was better than recall for no-lag (massed) items t(23) = 10.99, p < .001, d = 2.5. In Experiment 2, her final cued recall memory for next-day-reviewed (spaced) items was better than cued recall for same-day-reviewed (massed) items, t(20) = 17.6, p < .001, d = 4.1. CONCLUSIONS: This study demonstrates the spacing effect in a person with impaired episodic memory development and is the first to show long-term benefits of spacing in amnesia. Substantially slower learning-to-criterion suggests an alternate mechanism supporting the spacing effect, perhaps independent of the hippocampus. Spacing should be considered as a candidate memory intervention technique given its effectiveness in both short- and long-term learning settings.

Music therapy for early cognitive rehabilitation post-childhood TBI: an intrinsic mixed methods case study.

OBJECTIVE: The primary aim of this case study was to explore the behavioural changes of a paediatric patient in post-traumatic amnesia (PTA) during a music therapy session. A secondary objective was to measure the effect of the music therapy intervention on agitation. METHOD: Video data from pre, during and post-music therapy sessions were collected and analysed using video micro-analysis and the Agitated Behaviour Scale. RESULTS: The participant displayed four discrete categories of behaviours: Neutral, Acceptance, Recruitment and Rejection. Further analysis revealed brief but consistent and repeated periods of awareness and responsiveness to the live singing of familiar songs, which were classified as Islands of Awareness. Song offered an Environment of Potential to maximise these periods of emerging consciousness. The quantitative data analysis yielded inconclusive results in determining if music therapy was effective in reducing agitation during and immediately post the music therapy sessions. CONCLUSION: The process of micro-analysis illuminated four discrete participant behaviours not apparent in the immediate clinical setting. The results of this case suggest that the use of familiar song as a music therapy intervention may harness early patient responsiveness to foster cognitive rehabilitation in the early acute phase post-TBI.

Factor structure, reliability, and validity of the Frontal Systems Behavior Scale (FrSBe) in an acute traumatic brain injury population.

OBJECTIVE: This study investigated the psychometric properties of the Frontal Systems Behavior Scale (FrSBe) in an acute traumatic brain injury (TBI) population across indices of factor structure, reliability, and validity. METHOD: Data were collected from 101 individuals undergoing acute rehabilitation for moderate and severe TBI both upon emergence from posttraumatic amnesia and at hospital discharge, as well as from their family members or caregivers. RESULTS: Four separate confirmatory factor analyses (CFAs) suggested that the FrSBe's three-factor/three-subscale solution did not fit the data well, and follow-up CFAs employing a one-factor structure similarly yielded poor fit indices. Four exploratory factor analyses (EFAs) failed to produce factor solutions consistent with each other or that resembled the factor solution retained in the EFA during the FrSBe's initial construction. The FrSBe had sufficiently high internal consistency at the total-score and subscale-score levels, good convergent validity with other indices of TBI functioning, and good test-retest reliability in the family administration of the measure, but not in the patient administration. CONCLUSIONS: The FrSBe is an appropriate measure for use in an inpatient TBI population when using the total score and the family administration, though its subscales and patient administration warrant more rigorous examination.

The memory support system for mild cognitive impairment: randomized trial of a cognitive rehabilitation intervention.

OBJECTIVE: Individuals with amnestic mild cognitive impairment (MCI) have few empirically based treatment options for combating their memory loss. This study sought to examine the efficacy of a calendar/notebook rehabilitation intervention, the memory support system (MSS), for individuals with amnestic MCI. METHODS: Forty individuals with single domain amnestic MCI and their program partners were randomized to receive the MSS, either with training or without (controls). Measures of adherence, activities of daily living, and emotional impact were completed at the first and last intervention sessions and again at 8 weeks and 6 months post intervention. RESULTS: Training in use of a notebook/calendar system significantly improved adherence over those who received the calendars but no training. Functional ability and memory self-efficacy significantly improved for those who received MSS training. Change in functional ability remained significantly better in the intervention group than in the control group out to 8-week follow-up. Care partners in the intervention group demonstrated improved mood by 8-week and 6-month follow-ups, whereas control care partners reported worse caregiver burden by 6-month follow-up. CONCLUSIONS: Memory support system training resulted in improvement in activities of daily living and sense of memory self-efficacy for individuals with MCI. Although activities of daily living benefits were maintained out to 8 weeks post intervention, future inclusion of booster sessions may help extend the therapeutic effect out even further. Improved mood of care partners of trained individuals and worsening sense of caregiver burden over time for partners of untrained individuals further support the efficacy of the MSS for MCI.
