Depression in Poststroke Aphasia

Communication Public Health: An Integration of Audiology, Speech-Language Pathology, and Public Health

PURPOSE

Health care is advancing toward a collaborative and integrative approach that promotes general health and wellness while addressing health inequities through the consideration of broader social and economic factors that influence the well-being of the entire population. Recently, there has been growing evidence of public health concept applications in fields related to speech, language, and hearing. However, there is an outstanding need to explicitly define the intersection of public health, including prevention and health promotion, and the discipline of communication sciences and disorders (CSD) across the areas of education, clinical practice, research, and policy. The authors propose a definition for this intersection using the new term communication public health.

METHOD

This tutorial provides guidance on how to conceptualize communication public health and invites refinement and expansion of the intersection between public health and CSD. Because readers are experts in CSD, this tutorial aims to supplement existing knowledge with information on public health to achieve three main objectives: (a) increase knowledge of the application of public health concepts among speech, language, hearing, and related professionals (SLHP+); (b) introduce the concept of communication public health; and (c) discuss the relevance of communication public health across domains within CSD. The authors utilize the socioecological model to provide examples of applications.

RESULTS

The concept of communication public health is proposed as the collaborative area of CSD and public health, which encompasses prevention and promotion of equity in communication health through individual-, community-, and population-level efforts. The goals of communication public health are achieved through applications of public health principles in CSD education, clinical practice, research, and policy.

CONCLUSION

Communication public health defines an area of collaboration between public health and CSD in which SLHP+ can apply public health concepts to both advance communication health and address health disparities.

Knowledge, Beliefs, and Experiences With Mental Health Services and Help-Seeking in People With Aphasia and Care Partners

PURPOSE

Supporting psychological well-being in persons with aphasia (PWA) can improve social and health outcomes; however, PWA and their care partners (CPs) are often not receiving mental health support. Previous research explores this from the perspective of health care professionals.

AIMS

The aim of this study was to examine knowledge, beliefs, and experiences related to mental health services directly from PWA and CPs.

METHOD

The study included 11 PWA and 11 CPs. Participants completed a guided survey (virtual) with opportunities for elaboration related to the knowledge, beliefs, and experiences of mental health.

RESULTS

There was variability in personal preferences for referrals, types of coping strategies, and confidants for general thoughts and feelings and those specific to aphasia. PWA identified health care professionals as people to share thoughts and feelings, whereas CPs chose family and friends more often. Both CPs and PWA reported communication difficulty and finding a counselor as "sometimes" preventing access to services but cited fear and trust as "always" preventing access.

CONCLUSIONS

Knowledge, beliefs, and experience with help-seeking and mental health services are personal and variable. Assessing barriers unique to living with aphasia, such as communication challenges and locating a suitable counselor, must also be considered within more complex and personal barriers of fear and trust that are consistently reported in the general public. Health professionals across the continuum of aphasia care need to understand the communication challenges of living with aphasia in tandem with understanding individual differences to personalize approaches to mental health services and help-seeking.

Non-invasive brain stimulation in the treatment of post-stroke aphasia: a scoping review

PURPOSE

Aphasia is an acquired language impairment that commonly results from stroke. Non-invasive brain stimulation (NIBS) might accelerate aphasia recovery trajectories and has seen mounting popularity in recent aphasia rehabilitation research. The present review aimed to: (1) summarise all existing literature on NIBS as a post-stroke aphasia treatment; and (2) provide recommendations for future NIBS-aphasia research.

MATERIALS AND METHODS

Databases for published and grey literature were searched using scoping review methodology. 278 journal articles, conference abstracts/posters, and books, and 38 items of grey literature, were included for analysis.

RESULTS

Quantitative analysis revealed that ipsilesional anodal transcranial direct current stimulation and contralesional 1-Hz repetitive transcranial magnetic stimulation were the most widely used forms of NIBS, while qualitative analysis identified four key themes including: the roles of the hemispheres in aphasia recovery and their relationship with NIBS; heterogeneity of individuals but homogeneity of subpopulations; individualisation of stimulation parameters; and much remains under-explored in the NIBS-aphasia literature.

CONCLUSIONS

Taken together, these results highlighted systemic challenges across the field such as small sample sizes, inter-individual variability, lack of protocol optimisation/standardisation, and inadequate focus on aphasiology. Four key recommendations are outlined herein to guide future research and refine NIBS methods for post-stroke aphasia treatment.

Measuring Real-World Talk Time and Locations of People With Aphasia Using Wearable Technology

PURPOSE

Measuring real-world communication participation of individuals with aphasia is complicated. Historically, this has been estimated through subjective participant or proxy self-report. To address potential inaccuracies, objective measures such as "talk time" have been proposed. Although promising, technological barriers to collecting and quantifying everyday conversations have been documented (e.g., background noise interference, differentiating recorded speakers, and operating Bluetooth applications). This study explored the use of a novel laryngeal sensor and a Global Positioning System (GPS) tracker with the objective of measuring mean talk time per hour and participant locations across three 8-hr days.

METHOD

Sixteen participants utilized a wearable laryngeal sensor that captures physiological mechano-acoustic signals wirelessly, without recording speech content. The sensor differentiates speech from other laryngeal movements associated with swallowing and coughing. A GPS tracker was also issued to track daily locations. Semistructured interviews regarding feasibility and acceptability were conducted with participants at the end of the data collection period.

RESULTS

Across all participants, laryngeal sensor data were collected for a total of 38 days and GPS data for a total of 43 days, with a mean collection period of 8.21 hr (SD = 1.38) per day. Mean talk time per hour was 56.46 s (SD = 35.27). Participants were tracked at a mean of 2.09 locations daily (range: 1-6). Participants reported the devices were relatively comfortable to wear and easy to use.

CONCLUSIONS

Preliminary findings indicated that talk time of individuals with aphasia is limited, though variable. Higher fluency ratings were related to greater mean talk time per hour and locations tracked. Results suggest wearable technology is feasible to use and acceptable to people with aphasia. In the future, wearable devices may offer innovative ways to measure communication participation.

"It's day to day problems:" Experiences of people with aphasia who live alone

PURPOSE

Living alone is increasing and associated with health and social risks. Aphasia compounds these risks but there is little research on how living alone interacts with aphasia. This study is a preliminary exploration of this issue.

METHOD

Five people with aphasia who lived alone participated in two supported semi-structured interviews, with the second interview including sharing an artefact that held significance for living alone with aphasia. Interviews were recorded, transcribed verbatim, and analysed through reflexive thematic analysis.

RESULT

Four themes encompassed meaning-making about living alone with aphasia: relationships and reliance on others; risk, vulnerability, and uncertainty; loneliness and time alone; self-reliance and the need to keep busy. Participants had to continuously manage and renegotiate daily challenges around living alone with aphasia.

CONCLUSION

Living alone increases the risk of loneliness. For people with aphasia, the buffer against loneliness provided by social connection and meaningful activity may be more difficult to achieve because of communication challenges. While experiences vary, reliance on others, managing practical and administrative tasks, and negotiating risks are all important issues when alone. The intersection of living alone, loneliness, and living with aphasia needs more research, and more explicit clinical focus when discussing and planning intervention and support.

Person-centered care for people with aphasia: tools for shared decision-making

Shared decision-making is a fundamental aspect of person-centered care, and can and should be part of many different aspects of the rehabilitation process. Communication disabilities like aphasia, which affects people's ability to use and understand spoken and written language, can make shared decision-making especially challenging to the resources and skills of rehabilitation practitioners. The purpose of this narrative review is to provide a comprehensive description of tools that can support successful shared decision-making with people with aphasia in the rehabilitation environment. These tools and strategies are appropriate for use by physicians, nurses, social workers, physical therapists (also referred to as physiotherapists), occupational therapists, and other service or care providers. The important role of speech-language pathologists as consultants is also described. Case scenarios throughout the paper illustrate the application of recommended tools and strategies along with best practices.

Incidence of post-stroke depression symptoms and potential risk factors in adults with aphasia in a comprehensive stroke center

INTRODUCTION

Depression may be a frequent sequela after stroke, however, its incidence has rarely been reported. The likelihood of post-stroke depression (PSD) may relate to individual factors including the presence of aphasia, which also complicates PSD diagnosis. The current study's purpose was to investigate the incidence of PSD symptoms in adults with aphasia, compare it to the incidence of PSD symptoms in adults without aphasia, and to identify potential risk factors for developing PSD in adults with aphasia.

METHOD

Incidence proportions and relative risk were calculated using data compiled from 970 patient records at an urban tertiary care academic institution and comprehensive stroke center throughout the year of 2019. Focusing exclusively on adults with aphasia, the selected variables of age, gender, race, and aphasia severity were used to conduct logistic regression analyses to explore potential risk factors contributing to the development of PSD.

RESULTS

Adults with aphasia were 7.408 times more likely to exhibit PSD symptoms than adults without aphasia. Logistic regression controlling for the presence of aphasia showed a significant relationship between aphasia severity and post-stroke depression symptoms. Adults with aphasia were 2.06 times more likely to experience post-stroke depression symptoms with every 1-point increase in aphasia severity.

CONCLUSIONS

These findings align with earlier evidence identifying aphasia as a risk factor for experiencing PSD symptoms and also suggest aphasia severity is proportionate to the risk. This highlights the need for early identification of PSD symptoms in persons with aphasia in order to provide timely interventions.

Depression Risk in Post-Stroke Aphasia Patients: A Nationwide Population-Based Cohort Study

INTRODUCTION

Depression and aphasia impair the quality of life after a stroke. Studies linking depression risk to post-stroke aphasia (PSA) lacked confirmation using a large database.

METHODS

Using Taiwan's National Health Insurance claims data, we identified ≥18-year-old patients hospitalized for stroke from 2005 to 2009, and those diagnosed with aphasia during hospitalization or within 3 months after discharge were selected to form the aphasic group. We estimated depression incidence by December 31, 2018, and used the Cox proportional hazards model to estimate aphasia group to non-aphasia group hazard ratios (HRs).

RESULTS

With a median follow-up period of 7.91 and 8.62 years for aphasia (n = 26,754) and non-aphasia groups (n = 139,102), respectively, the incidence of depression was higher in the aphasia group than in the non-aphasia group (9.02 vs. 8.13 per 1,000 person-years), with an adjusted HR (95% confidence intervals [CI]) of 1.21 (1.15-1.29) for depression. The adjusted HRs (95% CI) of depression were homogenous for females, 1.26 (1.15-1.37); for males, 1.18 (1.09-1.27); for hemorrhagic stroke, 1.22 (1.09-1.37); and for ischemic stroke, 1.21 (1.13-1.30). Results in analyzing 25,939 propensity score-matched pairs demonstrated an equivalent effect.

CONCLUSION

Patients with PSA are at an increased risk of developing depression, regardless of sex or stroke type.

Effect of an extension speech training program based on Chinese idioms in patients with post-stroke non-fluent aphasia: A randomized controlled trial

BACKGROUND

Chinese idioms have potential to act as preliminary training material in studies on post-stroke aphasia.

OBJECTIVE

To explore an extension speech training program that takes Chinese idioms as context and expands them into characters, words, sentences and paragraphs and evaluate the effects of this program in patients with post-stroke non-fluent aphasia.

METHODS

This was a randomized controlled trial. We recruited patients with post-stroke non-fluent aphasia from the Renmin Hospital of Wuhan University from January 2021 to January 2022. Participants were randomly assigned to group I and group II. Patients in group I had treatment with extension speech training based on Chinese idioms, and those in group II had treatment with conventional speech rehabilitation training. The training period in both groups was 40 min daily for 2 weeks.

RESULTS

A total of 70 patients (group I, n = 34; and group II, n = 36) completed the trial and were analyzed according to protocol. There were no significant differences in baseline values between both groups. After intervention, the scores of oral expression, comprehension, and reading in the Aphasia Battery Of Chinese scale and the scores of the Comprehensive Activities of Daily Living questionnaire significantly improved in both groups (P <0.05), with group I benefiting more (P <0.05).

CONCLUSION

This extension speech training program based on Chinese idioms can improve the language function and daily communication ability of the patients with post-stroke non-fluent aphasia.

Donepezil alone and combined with intensive language-action therapy on depression and apathy in chronic post-stroke aphasia: A feasibility study

This study explored the feasibility and effectiveness of a short-term (10-week) intervention trial using Donepezil administered alone and combined with intensive language action therapy (ILAT) for the treatment of apathy and depression in ten people with chronic post-stroke aphasia. Outcome measures were the Western Aphasia Battery and the Stroke Aphasia Depression Questionnaire-21. Structural magnetic resonance imaging and ¹⁸fluorodeoxyglucose positron emission tomography were acquired at baseline and after two endpoints (Donepezil alone and Donepezil-ILAT). The intervention was found to be feasible to implement. Large treatment effects were found. Donepezil alone and combined with ILAT reduced aphasia severity, while apathy and depression only improved with Donepezil-ILAT. Structural and functional neuroimaging data did not show conclusive results but provide hints for future research. Given these overall positive findings on feasibility, language and behavioral benefits, further studies in larger sample sizes and including a placebo-control group are indicated.

Improved localization of language areas using single voxel signal analysis of unprocessed fMRI data

Activated brain regions can be visualized and localized with the use of fMRI (functional magnetic imaging). This is based on changes in the blood flow in activated regions, or more precisely on the hemodynamic response function (HRF) and the Blood-Oxygen-Level-Dependent (BOLD) effect. This study used a task-based fMRI examination with language paradigms in order to stimulate the language areas. The measured fMRI data are frequently altered by different preprocessing steps for the analysis and the display of activations. These changes can lead to discrepancies between the displayed and the truly measured location of the activations. Simple t-maps were created with unprocessed fMRI data, to provide a more realistic representation of the language areas. HRF-dependent single-voxel fMRI signal analysis was performed to improve the analyzability of these activation maps.

Using an Implementation Framework to Survey Outcome Measurement and Treatment Practices in Aphasia

PURPOSE

Best practices in the field of aphasia rehabilitation increasingly acknowledge a whole-person approach that values interventions aimed at reducing impairments, while also recognizing the impact of aphasia on participation and quality of life. Guided by the Consolidated Framework for Implementation Research (CFIR), this study aimed to examine whether current clinical practices along levels of service provision reflect this whole-person, multifaceted approach.

METHOD

Speech-language pathologists (SLPs) in the United States who provide intervention to people with aphasia across the continuum of care completed this cross-sectional online survey. Current outcome measurement and treatment practices were evaluated within the Living With Aphasia: Framework for Outcome Measurement via multiple-choice and open-text response questions. Data were analyzed descriptively and using ordinal logistic regression models to compare clinical practices along levels of service provision.

RESULTS

Data from 90 SLPs revealed that language and cognitive skills are assessed with equal consistency across clinical settings; however, functional communication, participation, and quality of life domains are prioritized in settings providing care to clients within the community. Psychological well-being is rarely assessed within clinical practice along most of the rehabilitation process and prioritized within the university clinic setting when clients are in the chronic stage of recovery.

CONCLUSIONS

Clinical practices related to a multifaceted approach to aphasia intervention are variable across levels of service provision. Further exploration of barriers and facilitators to multifaceted aphasia care along the domains of the CFIR is needed to provide an informed approach to implementing change.

Sex Differences in the Long-Term Consequences of Stroke

Stroke is the fifth leading cause of death and as healthcare intervention improves, the number of stroke survivors has also increased. Furthermore, there exists a subgroup of younger adults, who suffer stroke and survive. Given the overall improved survival rate, bettering our understanding of long-term stroke outcomes is critical. In this review we will explore the causes and challenges of known long-term consequences of stroke and if present, their corresponding sex differences in both old and young survivors. We have separated these long-term post-stroke consequences into three categories: mobility and muscle weakness, memory and cognitive deficits, and mental health and mood. Lastly, we discuss the potential of common preclinical stroke models to contribute to our understanding of long-term outcomes following stroke.

Spectrum of neuropsychiatric symptoms in chronic post-stroke aphasia

BACKGROUND

Neuropsychiatric symptoms (NPS) have been insufficiently examined in persons with aphasia (PWA) because most previous studies exclude participants with language and communication disorders.

AIM

To report a two-part study consisting of a literature review and an observational study on NPS in post-stroke aphasia.

METHODS

Study 1 reviewed articles obtained from PubMed, PsycINFO, Google Scholar and Cochrane databases after cross-referencing key words of post-stroke aphasia to NPS and disorders. Study 2 examined language deficits and activities of daily living in 20 PWA (median age: 58, range: 28-65 years; 13 men) with the Western Aphasia Battery-Revised and the Barthel Index, respectively. Informants of these 20 PWA were proxy-evaluated with the Neuropsychiatric Inventory and domain-specific scales, including the Stroke Aphasia Depression Questionnaire-10 item version and the Starkstein Apathy Scale. In addition, an adapted version of the Hospital Anxiety and Depression Scale was directly administered to the PWA themselves. This observational study is based on the baseline assessment of an intervention clinical trial (EudraCT: 2017-002858-36; ClinicalTrials.gov identifier: NCT04134416).

RESULTS

The literature review revealed a broad spectrum of NPS in PWA, including depression, anxiety, apathy, agitation/aggression, eating and sleep disorders, psychosis, and hypomania/mania. These findings alert to the need for improving assessment and treatment approaches of NPS taking into consideration their frequent occurrence in PWA. Study 2 showed that the 20 participants had mild- to-moderate aphasia severity and were functionally independent. A wide range of comorbid NPS was found in the post-stroke aphasic population (median number of NPS: 5, range: 1-8). The majority of PWA (75%) had depressive symptoms, followed by agitation/aggression (70%), irritability (70%), anxiety (65%) and appetite/eating symptoms (65%). Half of them also presented symptoms of apathy, whereas euphoria and psychotic symptoms were rare (5%). Domain-specific scales revealed that 45% of participants had apathy and 30% were diagnosed with depression and anxiety.

CONCLUSION

Concurrent NPS are frequent in the chronic period of post-stroke aphasia. Therefore, further research on reliable and valid assessment tools and treatment for this aphasic population is strongly warranted.

Categories of the International Classification of Functioning, Disability and Health in studies of people with aphasia: a scoping review

How Do You Do Talk Therapy With Someone Who Can't Talk? Perspectives From Mental Health Providers on Delivering Services to Individuals With Aphasia

Purpose Aphasia is correlated with depression and anxiety, and it has a negative impact on quality of life. Aphasia is also frequently misunderstood among mental health care providers. The aim of this study was to explore the experiences of mental health providers who provide services to people living with aphasia. Method Interpretative phenomenological analysis was used to analyze interviews of six mental health providers who had some experience in providing services to people with aphasia. Results Three main themes among mental health care providers' experiences providing services to people with aphasia were identified: barriers, interprofessional collaboration, and therapy looks different. Subthemes associated with barriers included insufficient training and knowledge of aphasia, the stigma of receiving mental health services, and accessibility to services. Subthemes related to interdisciplinary collaboration included referrals, knowledge and awareness, and strategies and tools. Subthemes supporting therapy looks different included a new approach to therapy and challenges. Conclusions Mental health providers' experiences reveal the need for an action-oriented approach to overcome barriers, a nontraditional approach to talk therapy for people with aphasia, and increased collaboration with speech-language pathologists (SLPs). Future research should explore expanding the collaboration between SLPs and mental health providers to increase shared knowledge and skills in issues related to reducing depression and anxiety to support the well-being of people with aphasia.

Internal Consistency and Convergent Validity of Self-Report and By-Proxy Measures of Depression in Persons With Aphasia

Purpose Depression assessment is challenging in persons with aphasia given their language impairment. Studies have used both self-report scales and by-proxy measures of depression in persons with aphasia. However, the validity of these measures has been called into question. The aim of this study was to conduct a preliminary investigation into aspects of validity of the community version of the Stroke Aphasia Depression Questionnaire (SADQ-10) and the Center for Epidemiological Studies Depression Scale-Revised (CESD-R). Method Twenty-four participants with chronic aphasia completed the CESD-R, the Patient-Reported Outcomes Measurement Information System Global Mental Health scale (PROMIS GMH), and the Dynamic Visual Assessment of Mood Scales (D-VAMS) while their caregivers completed the SADQ-10. Internal consistency of the CESD-R and the SADQ-10 and the convergent validity of the CESD-R, SADQ-10, PROMIS GMH, and D-VAMS were examined. Results The SADQ-10 and the CESD-R were internally consistent. The CESD-R was moderately correlated with the SADQ-10, PROMIS GMH, and D-VAMS. However, the SADQ-10 was not correlated with the PROMIS GMH and D-VAMS. Conclusions We suggest both the CESD-R and the SADQ-10 be used together to screen for depression in persons with aphasia. Further studies with larger sample sizes need to be conducted to establish validity of other depression screening instruments in person with aphasia.
