Effect of fenfluramine on convulsive seizures in CDKL5 deficiency disorder.

CDKL5 deficiency disorder (CDD) is an X-linked pharmacoresistant neurogenetic disorder characterized by global developmental delays and uncontrolled seizures. Fenfluramine (FFA), an antiseizure medication (ASM) indicated for treating convulsive seizures in Dravet syndrome, was assessed in six patients (five female; 83%) with CDD whose seizures had failed 5-12 ASMs or therapies. Median age at enrollment was 6.5 years (range: 2-26 years). Mean FFA treatment duration was 5.3 months (range: 2-9 months) at 0.4 mg/kg/day (n = 2) or 0.7 mg/kg/day (n = 4; maximum: 26 mg/day). One patient had valproate added for myoclonic seizures. The ASM regimens of all other patients were stable. Among five patients with tonic-clonic seizures, FFA treatment resulted in a median 90% reduction in frequency (range: 86%-100%). Tonic seizure frequency was reduced by 50%-60% in two patients with this seizure type. One patient experienced fewer myoclonic seizures; one patient first developed myoclonic seizures on FFA, which were controlled with valproate. Adverse events were reported in two patients. The patient with added valproate experienced lethargy; one patient had decreased appetite and flatus. No patient developed valvular heart disease or pulmonary arterial hypertension. Our preliminary results suggest that FFA may be a promising ASM for CDD. Randomized clinical trials are warranted.

Measuring the interactions of people with dementia and their conversation partners: a preliminary adaption of the Kagan measures of support and participation in conversation.

OBJECTIVE: While dementia can negatively affect communication, positive interactions can be facilitated by the conversation partners of people with dementia. There are few assessment tools designed to evaluate the support provided by the conversation partner and the resulting participation of the person with dementia. This study reports on an adaptation of the Measure of Support in Conversation (MSC) and Measure of Participation in Conversation (MPC) scales for use with people with dementia and their conversation partners (the MSC Dementia and MPC Dementia, respectively) and investigates the inter-and intra-rater reliability of these adapted measures. METHOD: The MSC-D and MPC-D scales were adapted from the original MSC and MPC scales to reflect current knowledge of communication and interaction involving people with dementia. Audio recordings of a total of 25 casual conversations, lasting 5-10 min, between a person with dementia and familiar aged care staff were independently rated by two raters to investigate inter-rater reliability and by one rater on two separate occasions to investigate intra-rater reliability. RESULTS: ICC analyses on the MSC-D indicated good inter-rater reliability (ICC = 0.718-0.812) and intra-rater reliability (ICC = 0.628-0.760). The MPC-D had excellent inter-rater reliability (ICC = 0.904-0.945) and intra-rater reliability (ICC = 0.925-0.957). 93.6% of all ratings were within 0.5 of each other on a nine point scale from 0 to 4. CONCLUSION: The results provide preliminary support for the use of these adapted scales. Further research is required to investigate the validity and reliability of these scales using video recordings and across a wider range of communication genres.

Identification of risk factors for failure in patients with skin and soft tissue infections.

PURPOSE: The purpose was to determine significant predictors of treatment failure of skin and soft tissue infections (SSTI) in the inpatient and outpatient setting. METHODS: A retrospective chart review of patients treated between January 1, 2005 to July 1, 2016 with ICD-9 or ICD-10 code of cellulitis or abscess. The primary outcome was failure defined as an additional prescription or subsequent hospital admission within 30 days of treatment. Risk factors for failure were identified through multivariate logistic regression. RESULTS: A total of 541 patients were included. Seventeen percent failed treatment. In the outpatient group, 24% failed treatment compared to 9% for inpatients. Overweight/obesity (body mass index (BMI) > 25 kg/m2) was identified in 80%, with 15% having a BMI >40 kg/m2. BMI, heart failure, and outpatient treatment were determined to be significant predictors of failure. The unit odds ratio for failure with BMI was 1.04 (95% [Cl] = 1.01 to 1.1, p = 0.0042). Heart failure increased odds by 2.48 (95% [Cl] = 1.3 to 4.7, p = 0.0056). Outpatients were more likely to fail with an odds ratio of 3.36. CONCLUSION: Patients with an elevated BMI and heart failure were found to have increased odds of failure with treatment for SSTIs. However, inpatients had considerably less risk of failure than outpatients. These risk factors are important to note when making the decision whether to admit a patient who presents with SSTI in the emergency department. Thoughtful strategies are needed with this at-risk population to prevent subsequent admission.

Fluoroquinolone-Related Neuropsychiatric Events in Hospitalized Veterans.

OBJECTIVE: To measure the incidence and risk factors for fluoroquinolone (ciprofloxacin, moxifloxacin, and levofloxacin)-associated psychosis or delirium in a veteran population. METHODS: A retrospective study was conducted in the Western New York Veterans Affairs Health System (2005-2013). Participants were hospitalized veterans receiving a fluoroquinolone for at least 48 hours (n = 631). Cases of delirium or psychosis were defined by the Diagnostic and Statistical Manual of Mental Disorders-IV criteria, and the Naranjo scale (score ≥ 1) was used to determine the probability of the adverse drug reaction being related to fluoroquinolones. A bivariate analysis of covariates followed by a multivariate logistic regression was used to determine predisposing factors to the development of delirium/psychosis. RESULTS: The mean age of the population was 71.5 years (range: 22-95). Fluoroquinolone-associated delirium/psychosis occurred in 3.7% of the inpatients studied (n = 23). The median Naranjo score was 3 indicating a possible association. Psychosis/delirium occurred in 3.6% of ciprofloxacin-treated patients (n = 14/391), 4.5% of patients-treated with moxifloxacin (n = 9/200), and 0% of those receiving levofloxacin (n = 0/40); p = 0.4. Significant risk factors for development of delirium/psychosis in patients receiving a fluoroquinolone in the multivariate logistical regression included typical antipsychotic use (OR, 5.4; 95% CI: 1.4-16.7) and age. A 10-year increase in age was associated with a 1.8-fold greater odds of a neuropsychiatric event. CONCLUSIONS: Fluoroquinolones may be more commonly associated with delirium/psychosis than originally reported in this veteran population. Caution should be used when prescribing a fluoroquinolone for patients on typical antipsychotics and those of advanced age.

Is it all bleak? A systematic review of factors contributing to relationship change in dementia.

ABSTRACTBackground:The care of community-dwelling people with dementia often occurs in the context of pre-existing family relationships. The presence of dementia can result in changes to the quality of those relationships. The purpose of this systematic review is to identify factors that enhance or challenge the quality of spousal or offspring relationships in the context of dementia. METHODS: Both qualitative and quantitative studies were included in a systematic review of the literature. Thematic analysis of results was conducted that examined factors related to the relationship quality of community dwelling people with dementia and their spousal or offspring carer. Meta-analysis was not possible due to the heterogeneity of the included studies. RESULTS: Four themes were extracted from seven qualitative studies: connection to the carer role; identity of the people with dementia; current efforts to maintain relationship connection; and the dyads response to dementia. Each of these four themes incorporated positive and negative facets that impacted on relationship quality. An analysis of nine quantitative and one mixed methods studies identified four domains: influence of dementia characteristics; connection within the dyad; relationship response to stress and carer burden; and carer demographic factors. CONCLUSIONS: The findings of this review highlight relationship factors that are important for supporting relationship quality for the people with dementia and the carer individually, as well as for the dyad together. These findings extend an existing framework of relationship quality in dementia. Implications for interventions to enhance relationship quality in the dementia context are discussed.

Proper Antibiotic Use in a Home-Based Primary Care Population Treated for Urinary Tract Infections.

OBJECTIVE: To evaluate the trends associated with diagnosis and treatment of urinary tract infections (UTI) in a home-based primary care population of Veterans Health System patients from 2006 to 2015. DESIGN: Retrospective cohort study. SETTING: Veterans Healthcare System. PARTICIPANTS: Home-based primary care patients treated for UTI from 2006 to 2015. INTERVENTIONS: None. MAIN OUTCOME MEASURE: Appropriate therapy was determined based on the McGeer criteria. Multivariate logistic regression was used to determine factors leading to appropriate UTI treatment. RESULTS: Of 366 available patients, 68 (18.6%) were tested for a UTI. Appropriate therapy occurred in 26% of patients. Allergy to any antibiotic increased the odds of appropriate treatment (odds ratio [OR] = 5.6, 95% confidence interval [CI] 1.5-23.2). Flank pain and increased urinary frequency also increased the likelihood of being treated appropriately (OR = 25.9, 95% CI 2.9-584.0 and OR = 4.49, 95% CI 0.99-21.2, respectively). CONCLUSION: Antibiotics were overused for treating UTIs in the homebound population. Patients with flank pain, increased urinary frequency, and antibiotic allergy were more likely to receive appropriate treatment. Pharmacists, therefore, have a viable opportunity to increase appropriate antibiotic prescribing in the home-based primary care population.

Obesity and Heart Failure as Predictors of Failure in Outpatient Skin and Soft Tissue Infections.

The purpose of this study was to evaluate risk factors for failure of antibiotic treatment within 30 days for uncomplicated skin infections of outpatients treated in a Veterans Affairs hospital. A retrospective chart review of outpatients between January 2006 and July 2015 with an ICD-9 (International Statistical Classification of Diseases and Related Health Problems) code of cellulitis or abscess was included in the analysis. The primary outcome was success versus failure of the antibiotic, with failure defined as another antibiotic prescribed or hospitalization within 30 days for the original indication. A total of 293 patients were included in the final analysis, 24% of whom failed within 30 days. Obesity/overweight (body mass index [BMI] of >25 kg/m2) was identified in 83% of the overall population, with 16% of that population having a BMI greater than 40 kg/m2 An elevated mean BMI of 34.2 kg/m2 (P = 0.0098) was found in the subset of patients who failed oral antibiotics compared to a BMI of 31.32 kg/m2 in patients who were treated successfully. Additionally, the patients who failed had an increased prevalence of heart failure at 16% (P = 0.027). Using multivariate logistic regression, BMI and heart failure were determined to be significant predictors of antibiotic prescription failure. Each 10-kg/m2 unit increase in BMI was associated with a 1.62-fold-greater odds of failure. A diagnosis of heart failure increased the odds of failure by 2.6-fold (range, 1.1- to 5.8-fold). Outpatients with uncomplicated skin infections with an elevated BMI and heart failure were found to have increased odds of failure, defined as hospitalization or additional antibiotics within 30 days.

Quality of Life in Childhood Epilepsy in pediatric patients enrolled in a prospective, open-label clinical study with cannabidiol.

Recent clinical trials indicate that cannabidiol (CBD) may reduce seizure frequency in pediatric patients with certain forms of treatment-resistant epilepsy. Many of these patients experience significant impairments in quality of life (QOL) in physical, mental, and social dimensions of health. In this study, we measured the caregiver-reported Quality of Life in Childhood Epilepsy (QOLCE) in a subset of patients enrolled in a prospective, open-label clinical study of CBD. Results from caregivers of 48 patients indicated an 8.2 ± 9.9-point improvement in overall patient QOLCE (p < 0.001) following 12 weeks of CBD. Subscores with improvement included energy/fatigue, memory, control/helplessness, other cognitive functions, social interactions, behavior, and global QOL. These differences were not correlated to changes in seizure frequency or adverse events. The results suggest that CBD may have beneficial effects on patient QOL, distinct from its seizure-reducing effects; however, further studies in placebo-controlled, double-blind trials are necessary to confirm this finding.

Evaluating the MESSAGE Communication Strategies in Dementia training for use with community-based aged care staff working with people with dementia: a controlled pretest-post-test study.

AIMS AND OBJECTIVES: The study aims to evaluate the effects of a communication skills training programme on community aged care staff's knowledge of communication support in dementia and on staff's care experience. BACKGROUND: Dementia can lead to impairments in communication. Therefore, quality community-based dementia care requires that staff be skilled communicators, equipped to facilitate interactions with people with dementia. The current investigation evaluated the effectiveness of the MESSAGE Communication Strategies in Dementia for Care Staff training programme with respect to knowledge of communication support and the staff/caregiver experience. DESIGN: A multi-centre controlled pretest/post-test design with randomised cohort allocation was used. Outcome measures were completed at baseline, immediately after training (training group only), and at three-month follow-up. METHODS: Thirty-eight care staff working in community aged care participated and completed all outcome measures (training = 22; control = 16).Training and control groups completed the following outcome measures: knowledge of communication support strategies, self-efficacy, preparedness to provide care, strain in nursing care and attitude to dementia care. Staff in the training group provided written feedback on the training. RESULTS: A significant improvement in knowledge scores from baseline was found for the training group both immediately after training and at three-month follow-up. There was also a significant training effect for self-efficacy and preparedness to provide care. No significant difference was found for the control group for any measure. No significant training effects were found for measures of strain or attitudes to dementia care. Feedback from staff suggests that the training was well received. CONCLUSIONS: The MESSAGE training was positively received by staff and had a significant effect on care staff knowledge, and confidence to provide care for people with dementia. RELEVANCE TO CLINICAL PRACTICE: The easily accessible multimedia training programme is well received by staff and has the potential to improve quality of care.

"Time is a Big Factor": Aged-Care Workforce Perspectives on Communication Partner Training for Working With Residents With Dementia.

Many individuals who reside in permanent residential aged care (RAC) have a diagnosis of dementia, with the majority experiencing a communication disorder. Existing literature has placed an emphasis on the need for staff to undertake communication partner training. This study aimed to investigate the preferences of RAC staff, and their perceived barriers and facilitators to workplace training. Through an exploratory cross-sectional online survey, a sample of RAC workers in Australia were recruited (n = 104). Descriptive statistics revealed that the majority of participants preferred training to be delivered face to face and being paid for participation. Through content analysis of open-ended questions, seven categories were identified regarding perceived barriers and facilitators for communication partner training in the workplace. These included staff shortages, time pressures, remuneration and training delivery method, and quality of the educators. Additionally, management attitudes were pertinent. These findings may inform the development and outcomes of future communication partner training in RAC.

A dual task priming investigation of right hemisphere inhibition for people with left hemisphere lesions.

BACKGROUND: During normal semantic processing, the left hemisphere (LH) is suggested to restrict right hemisphere (RH) performance via interhemispheric suppression. However, a lesion in the LH or the use of concurrent tasks to overload the LH's attentional resource balance has been reported to result in RH disinhibition with subsequent improvements in RH performance. The current study examines variations in RH semantic processing in the context of unilateral LH lesions and the manipulation of the interhemispheric processing resource balance, in order to explore the relevance of RH disinhibition to hemispheric contributions to semantic processing following a unilateral LH lesion. METHODS: RH disinhibition was examined for nine participants with a single LH lesion and 13 matched controls using the dual task paradigm. Hemispheric performance on a divided visual field lexical decision semantic priming task was compared over three verbal memory load conditions, of zero-, two- and six-words. Related stimuli consisted of categorically related, associatively related, and categorically and associatively related prime-target pairs. Response time and accuracy data were recorded and analyzed using linear mixed model analysis, and planned contrasts were performed to compare priming effects in both visual fields, for each of the memory load conditions. RESULTS: Control participants exhibited significant bilateral visual field priming for all related conditions (p < .05), and a LH advantage over all three memory load conditions. Participants with LH lesions exhibited an improvement in RH priming performance as memory load increased, with priming for the categorically related condition occurring only in the 2- and 6-word memory conditions. RH disinhibition was also reflected for the LH damage (LHD) group by the removal of the LH performance advantage following the introduction of the memory load conditions. CONCLUSIONS: The results from the control group are consistent with suggestions of an age related hemispheric asymmetry reduction and indicate that in healthy aging compensatory bilateral activation may reduce the impact of inhibition. In comparison, the results for the LHD group indicate that following a LH lesion RH semantic processing can be manipulated and enhanced by the introduction of a verbal memory task designed to engage LH resources and allow disinhibition of RH processing.

Memory and communication support strategies in dementia: effect of a training program for informal caregivers.

BACKGROUND: People with dementia have a range of needs that are met by informal caregivers. A DVD-based training program was developed using research-based strategies for memory and communication in dementia. The effectiveness of the training on the caregiver experience and the well-being of the person with dementia was evaluated. METHODS: A pre-test/post-test controlled trial was undertaken with caregiver-care-recipient dyads living in the community. Measures of the carers' knowledge of memory and communication strategies, burden, positive perceptions of caregiving, and perceptions of problem behaviors were taken pre- and three months post-intervention. The depression and well-being of the person with dementia were also evaluated. Satisfaction with the training and feedback were measured. RESULTS: Twenty-nine dyads (13 training group, 16 control group) participated. Bonferroni's correction was made to adjust for multiple comparisons, setting α at 0.00385. A significant improvement was found in caregivers' knowledge for the training group compared to the control group (p = 0.0011). The training group caregivers reported a reduction in the frequency of care recipient disruptive behaviors (p = 0.028) and increased perceptions of positive aspects of caregiving (p = 0.039), both at a level approaching significance. The training group care recipients had increased frequency of verbally communicated depressive behaviors at a level approaching significance (p = 0.0126). The frequency of observed depressive behaviors was not significantly different between groups. CONCLUSIONS: This approach to training for caregivers of people with dementia appears promising for its impact on knowledge and the caregiving experience. Further research could monitor the impact of the training on broader measures of depression and well-being, with a larger sample.

Advocating the rights of people with dementia to contribute to research: Considerations for researchers and ethics committees.

OBJECTIVE: Research involving people with dementia is vital to appropriately inform policy and practice decisions affecting this population. As dementia-care researchers, we frequently advocate to Human Research Ethics Committees for the right of people with dementia to choose whether to participate in research. This brief report provides some considerations for researchers and ethics committees. METHOD: Descriptive summary of principles that argue for inclusion of people with dementia in research studies. RESULTS: Specifically excluding people living with dementia from research because of perceived cognitive impairment is inappropriate in light of human rights principles and the right to contribute to evidence-based care. CONCLUSIONS: There is a difference between capacity to provide informed consent and ability to provide perspectives that are valid for each individual. Providing the opportunity for a person with dementia to participate in research and offering support to do this is a matter of human rights.

Risk Factors for Mortality in an Older Veteran Population With infective Endocarditis.

OBJECTIVE: To determine 30-day and 1-year mortality in patients treated for infective endocarditis (IE) in a VA population. The secondary objective was to identify risk factors for increased risk of mortality in veterans diagnosed with IE. DESIGN: A retrospective cohort study. SETTING: Veterans Affairs Western New York Healthcare System PARTICIPANTS: Patients who had a diagnosis of IE between the years 2005 and 2016. Patients were identified via International Classification of Diseases (ICD) codes. INTERVENTIONS: None. MAIN OUTCOME MEASURES: Factors for death and survival were compared using a bivariate analysis. Significant factors were built into a multivariate logistic regression analysis to determine risk factors for death at 30 days and 1 year. RESULTS: Between 2005 and 2016, there were 153 patients with IE. All-cause mortality at 30 days was 14% versus 39% at 1 year. Patients were more likely to die at 1 year with higher Pitt Bacteremia Scores, older age, and lower number of minor criteria according to Duke Criteria. Comorbidities were similar between groups. CONCLUSIONS: Older patients with higher Pitt Bacteremia Scores and lower numbers of minor criteria are more likely to experience mortality at one year. Given the high rates of death at one year, close monitoring, even after completion of therapy may be necessary in older patients. Senior care pharmacists are in a unique position to monitor these patients.

Hear-Communicate-Remember: Feasibility of delivering an integrated intervention for family caregivers of people with dementia and hearing impairment via telehealth.

PURPOSE: To evaluate the feasibility of Hear-Communicate-Remember, a training programme developed for family caregivers of people with dementia and hearing impairment that integrated hearing, communication and memory strategies, which was intended to be delivered via telehealth. MATERIALS AND METHODS: Participants included six dyads consisting of adults with dementia and hearing impairment and their family caregivers. Data collection involved a combination of semi-structured interviews, self-report questionnaires and field notes. RESULTS: Analysis of the qualitative interviews revealed four themes: appropriateness of intervention resources, considerations for the delivery of intervention via telehealth, knowledge and application of intervention strategies, and impact of the intervention on day-to-day life. Results from the satisfaction survey indicated that caregiver participants were mostly satisfied with all aspects of the intervention except the use of some technological components. The field notes described challenges with implementation via telehealth. CONCLUSIONS: Future research involving a cohort comparison study with a larger cohort of dyads is needed to establish treatment efficacy.

Pharmacotherapy with sertraline rescues brain development and behavior in a mouse model of CDKL5 deficiency disorder.

Mutations in the X-linked cyclin-dependent kinase-like 5 (CDKL5) gene cause a severe neurodevelopmental disorder, CDKL5 deficiency disorder (CDD). CDKL5 is fundamental for correct brain development and function, but the molecular mechanisms underlying aberrant neurologic dysfunction in CDD are incompletely understood. Here we show a dysregulation of hippocampal and cortical serotonergic (5-HT) receptor expression in heterozygous Cdkl5 knockout (KO) female mice, suggesting that impaired 5-HT neurotransmission contributes to CDD. We demonstrate that targeting impaired 5-HT signaling via the selective serotonin reuptake inhibitor (SSRI) sertraline rescues CDD-related neurodevelopmental and behavioral defects in heterozygous Cdkl5 KO female mice. In particular, chronic treatment with sertraline normalized locomotion, stereotypic and autistic-like features, and spatial memory in Cdkl5 KO mice. These positive behavioral effects were accompanied by restored neuronal survival, dendritic development and synaptic connectivity. At a molecular level, sertraline increased brain-derived neurotrophic factor (BDNF) expression and restored abnormal phosphorylation levels of tyrosine kinase B (TrkB) and its downstream target the extracellular signal-regulated kinase (ERK1/2). Since sertraline is an FDA-approved drug with an extensive safety and tolerability data package, even for children, our findings suggest that sertraline may improve neurodevelopment in children with CDD.

Voice Outcome Measures for Adult Patients With Unilateral Vocal Fold Paralysis: A Systematic Review.

OBJECTIVES: Unilateral vocal fold paralysis (UVFP) typically results in marked changes in voice quality and performance and has a significant impact on quality of life. Treatment approaches generally aim to restore glottal closure for phonation and improve vocal function. There are a wide range of voice outcome measures that are available to measure the treatment effect. Careful selection of voice outcome measures is required to ensure that they are adequate for purpose and are psychometrically sound to detect the treatment effect. This article aims to critically evaluate the literature for voice outcome measures that are used for patients with UVFP. STUDY DESIGN: Systematic review. METHODS: Nine databases were searched for UVFP treatment studies published since 2003 (n = 2,484 articles). These articles and their references were screened using inclusion/exclusion criteria, including population characteristics, treatment, voice outcomes, and study findings. Data from the included articles was extracted and appraised with respect to multidimensionality, timing, selection rationale, validity, reliability, and responsiveness to change of the voice outcome measures. RESULTS: A total of 29 studies met the inclusion criteria for the systematic review. These studies showed considerable variability in the rationale, selection, and application of voice outcome measures for reporting the treatment effect for patients with UVFP. CONCLUSION: There is currently a significant disparity in the selection and use of voice outcome measures for patients with UVFP. A set of principles around selection rationale, validity, reliability, and responsiveness to change is proposed to enhance the judicious selection of voice outcome measures for this patient group.

Conversational trouble and repair in dementia: Revision of an existing coding framework.

A decline in the effectiveness of everyday conversation is often observed for people with dementia. This study explored conversational trouble and repair between people with dementia residing in residential care and professional care staff. The aim was to examine the utility of an existing conversational trouble and repair framework by Watson, Carter and Chenery (1999) in a comparatively larger sample. Twenty conversations were coded for dementia-specific trouble and repair; however, the original framework could not adequately accommodate the variety of trouble and repair within the dataset. The data was subsequently used to inform a revised framework, which captures a wide spectrum of trouble and repair in dementia and offers more precise codes to researchers and clinicians working with this clinical population. Examples of divergent coding strategies between the original and revised framework are provided as well as examples of trouble and repair patterns observed in both carers and people with dementia.

Speech-Language Pathologist Interventions for Communication in Moderate-Severe Dementia: A Systematic Review.

Purpose: The purpose of this study is to evaluate the evidence for direct and indirect interventions for communication in people with moderate-severe dementia. Method: A systematic search of the literature was conducted, as per the Preferred Reporting Items for Systematic Reviews and Meta-Analysed guidelines, across 8 electronic databases. Studies were included if they included direct or indirect interventions, which could be administered by a speech-language pathologist to people with moderate-severe dementia (defined as having Mini-Mental State Examination of ≤ 15; Folstein, Folstein, & McHugh, 1975). Studies also were required to include outcome measures, which reported on communication function or participation and/or well-being related to communication. Included studies were evaluated for methodological quality using the McMaster critical appraisal tool (Law et al., 1998). Results: Eleven studies met the inclusion criteria. Ten of these studies related to direct interventions and included cognitive stimulation approaches using group (n = 5) or individual therapy (n = 1); cognitive training, including naming therapy (n = 1) and spaced retrieval training (n = 1); and cognitive rehabilitation approaches using augmentative and alternative communication (n = 2). One study reported an indirect intervention: conversation partner training. Due to the heterogeneity of studies, a meta-analysis was unable to be conducted. A descriptive synthesis of results indicated that interventions generally resulted in positive changes to communication and related quality-of-life outcomes compared with baseline or control groups. Conclusions: Preliminary evidence was found to support communication interventions for people with moderate-severe dementia. The use of cognitive stimulation approaches, which use a group treatment model and conversation, as a therapy medium show promise as direct intervention options. Implications for clinical practice for speech-language pathologists and future research are discussed. Supplemental Material: https://doi.org/10.23641/asha.5985241.

Toward the Development of SMART Communication Technology: Automating the Analysis of Communicative Trouble and Repair in Dementia.

BACKGROUND AND OBJECTIVES: Communication difficulties have been reported as one of the most stress-inducing aspects of caring for people with dementia. Notably, with disease progression comes an increase in the frequency of communication difficulty and a reduction in the effectiveness of attempts to remedy breakdowns in communication. The aim of the current research was to evaluate the utility of an automated discourse analysis tool (i.e., Discursis) in distinguishing between different types of trouble and repair signaling behaviors, demonstrated within conversations between people with dementia and their professional care staff. RESEARCH DESIGN AND METHODS: Twenty conversations between people with dementia and their professional care staff were human-coded for instances of interactive/noninteractive trouble and typical/facilitative repair behaviors. Associations were then examined between these behaviors and recurrence metrics generated by Discursis. RESULTS: Significant associations were identified between Discursis metrics, trouble-indicating, and repair behaviors. DISCUSSION AND IMPLICATIONS: These results suggest that discourse analysis software is capable of discriminating between different types of trouble and repair signaling behavior, on the basis of term recurrence calculated across speaker turns. The subsequent recurrence metrics generated by Discursis offer a means of automating the analysis of episodes of conversational trouble and repair. This achievement represents the first step toward the future development of an intelligent assistant that can analyze conversations in real time and offers support to people with dementia and their carers during periods of communicative trouble.
