“…For example, executive functioning incorporates skills 20 pertaining to shifting, planning and goal-oriented behavior, whereas, attention may be further 21 differentiated into sustained, selective and divided attention (Lezak, Howieson, & Loring, 22 2004;Murray, 2012). The presence of concomitant cognitive impairments in adults with post-23 stroke aphasia has been well documented (El Hachioui et al, 2014), and impairments in the 24 domains of attention (Erickson, Goldinger, & LaPointe, 1996;Glosser & Goodglass, 1990;25 Murray, 2012;Murray, Holland, & Beeson, 1997;Sturm & Willmes, 1991;Villard & Kiran, 26 2015), memory (Beeson, Bayles, Rubens, & Kaszniak, 1993;Mayer & Murray, 2012;assessment significantly correlated with both spontaneous recovery and treatment success. 1…”

Purpose:The relationship between cognitive abilities and aphasia rehabilitation outcomes is 2 complex and remains poorly understood. This study investigated the influence of language 3 and cognitive abilities on anomia therapy outcomes in adults with aphasia. 4Methods: 34 adults with chronic aphasia participated in Aphasia Language Impairment and 5Functioning Therapy. A language and cognitive assessment battery, including 3 baseline 6 naming probes, was administered prior to therapy. Naming accuracy for 30 treated and 30 7 untreated items was collected at post-therapy and 1 month follow-up. Multiple regression 8 models were computed to evaluate the relationship between language and cognitive abilities 9 at baseline and anomia therapy outcomes.

“…77,81,[114][115][116] In contrast, two studies examining predictors in patients with aphasia found that better scores on a composite measure of phonology and non-linguistic cognitive markers predicted better outcomes one year post-stroke. 77,115 Persad and colleagues looked at predictors in two different ICAPs and similarly found that there was no difference between responders and non-responders on the WAB-R AQ on factors of age, time post-onset, and gender, but did find a difference in severity of aphasia. 73 Similar to this thesis, there was a trend towards older participants who were longer time post-onset having less change on the AQ measure.…”

“…While some of these factors are difficult to measure or have not been routinely measured, some research has shown that they may positively impact recovery. [77][78][79] Other research has found that such characteristics had minimal or mixed effect on recovery from aphasia. 80,81 Evidence is equivocal about the extent to which stroke-related or neurological characteristics such as time post onset, type of aphasia, and location and size of the lesion impact recovery.…”

“…78 However, confounding pre-morbid neurological and health status characteristics, (i.e., learning disabilities, high blood pressure, diabetes, and depression) can impact deficits and recovery in ways that are not yet known. 77,114,116 Personal characteristics and environments such as motivation, personal beliefs, and family support may also impact recovery. 11,79,117 A challenge in interpreting prognostic studies is that there is sparse information regarding the type and amount of speech-language treatment participants received during long-term recovery.…”

Outcomes of an Intensive Comprehensive Aphasia Program

Intensive comprehensive aphasia programs (ICAP) have increased over the last decade in the US and abroad. The increase in the number of clinical programs has outpaced the research that is necessary to establish the efficacy and effectiveness of these specialized treatment programs. The ICAP model incorporates principles from neuroplasticity, that is, intensive treatment provides a platform for the massed practice and repetition required to change the brain. It also incorporates comprehensive treatment that addresses not only impairment-based language deficits but also personal goals related to participation.Programs which offer intensive comprehensive treatment can provide up to 120 hours of treatment over several weeks (e.g., six hours a day, five days a week for four weeks). ICAPs are different from other types of aphasia services which generally provide two to three hours of therapy a week. This thesis examined one ICAP in depth to describe the structure, process, and outcomes using Donabedian's model of health care evaluation. This thesis also described the experiences of the ICAP from the perspectives of the primary stakeholders.Study One (Chapter Two) was a retrospective quantitative study using behavioral measures from an existing database that documented the outcomes of participants with aphasia. It found that first-time participants improved significantly in impairment-and participationbased measures, demonstrating moderate to large effect sizes. Participant characteristics were examined to determine if improvements were related to age, time post-onset, or type and severity of aphasia. None of these factors had an impact on the amount of change measured. Given that some participants did not make significant gains on a primary outcome measure, the Western Aphasia Battery -Revised Aphasia Quotient (WAB-R AQ), Study Two (Chapter Three) examined whether participant characteristics at baseline could predict who would make significant gains on the WAB-R AQ. Age and months post-onset were significantly different between the responder and the non-responder groups. Those who showed most gains on average were younger and a longer time post-onset. A logistic regression was performed and results indicated that only age (younger participants) predicted who would respond to treatment. Time post-onset, type and severity of aphasia, naming, non-verbal cognition, and communication confidence did not show significance in a predictive model. Studies Three and Four were qualitative studies involving interviews with therapists (Chapter Four) and people with aphasia and their families (Chapter Five). Both studies were 3 conducted using a phenomenological approach which allowed for the interviewees to describe their experiences in a semi-structured interview. The clinicians described the intensity of the therapy, the rewards, and challenges of the program. Therapists also considered that the ICAP model of service delivery had several positive benefits for them, but acknowledged that the intensity of therapy was challe...

“…The incidence of cognitive impairments in adults with aphasia is high. El Hachioui et al (2014) found that out of a sample of 147 adults with aphasia, 88% of individuals' demonstrated impairment in at least one cognitive domain at 3 months post stroke onset and 80% of individuals continued to demonstrate cognitive impairment(s) at 12 months post-stroke. Consequently, the presence of comorbid cognitive impairments in adults with aphasia is likely to influence participation in rehabilitation and negatively affect therapy outcomes.…”

Nonlinguistic Cognitive Impairment in Poststroke Aphasia

Abstract: Standard nonlinguistic cognitive examination is recommended in aphasic stroke patients. Nonlinguistic cognitive impairments are common and associated with poor functional outcome and depression, especially in patients with persisting aphasia.
