Impairment caused by non-fluent aphasia often results in the omission and substitution of inflectional markers. Cross-linguistic work has revealed differential patterns of aphasic impairment across languages. This study aims to determine how non-fluent aphasia is manifested in English-based Caribbean creole languages, namely Jamaican Creole English (JCE) and Guyanese Creole (GC). The use of inflectional morphology is variable in English-based Caribbean creole languages. Therefore, in aphasic creole speech, it is difficult to ascertain the status of a grammatical omission as a valid creole feature or as a sign of impairment. I argue that Seymour’s et al. (1998) contrastive-noncontrastive schema can be useful for differentiating between normal and disordered creole features. The data in this study was obtained from a creole speaker with aphasic impairments. The data was later transcribed and analyzed. The results of this study appear to suggest that grammatical markers may form a hierarchy of susceptibility to aphasic impairment. Tense, agreement and aspectual markers along with auxiliaries and copulas appear to be more susceptible to impairment in disordered creole speech than plural markers, personal and demonstrative pronouns and articles. / Thesis / Master of Science (MSc) / Non-fluent aphasia is a language disorder caused by stroke and other types of severe brain trauma. This disorder can affect an individual's ability to produce grammatical words and suffixes in different ways depending on the language that they speak. This study seeks to determine how non-fluent aphasia affects English-based Caribbean creole languages, namely Jamaican Creole English (JCE) and Guyanese Creole (GC). Grammatical suffixes are optional in English-based Caribbean creole languages; therefore, it is difficult to determine whether or not an omitted grammatical suffix is a valid creole feature or a sign of impairment. I argue that Seymour’s et al. (1998) contrastive-noncontrastive schema can be useful for differentiating between normal and disordered creole features. The data in this study was obtained from a creole speaker with aphasic impairments. The data was later transcribed and analyzed. The results of this study appear to suggest that certain grammatical markers are more prone error than others in aphasic creole speech. Markers that carry tense, agreement and aspectual information along with auxiliaries and copulas appear to be more susceptible to impairment than plural markers, personal and demonstrative pronouns and articles.

This study explored posttraumatic growth (PTG) in people with aphasia and is the qualitative arm of a larger mixed-methods study. After an initial experimental session, 23 people with aphasia (PWA; 12 females and 11 males) completed a 60-minute semi-structured interview during which participants expanded on previously-given questionnaire responses and then answered five additional open-ended questions about communication in their daily life. Interviews were transcribed orthographically and coded using reflexive codebook analysis. A stakeholder with aphasia was consulted to gain insight from an insider's perspective about whether codes and themes captured the experiences of aphasia. Reflexive codebook analysis revealed two themes. Within the first theme, "Recovery is a Journey," there were two categories: "Moving Toward Growth" and "Engagement." The second theme, "Having Aphasia is Challenging, but I've Grown," included four categories: "Challenges and Reactions," "Perception of Self," "General Philosophy of Life," and "Relatedness." Findings suggest that PWA experience PTG across all three primary domains: (1) changed perception of self, (2) changed relationship with others, and (3) changed general philosophy of life and that the challenging circumstances associated with aphasia were integral to the development of PTG. Findings also highlight that PTG does not necessarily develop in a linear trajectory for PWA, but that processes such as acceptance and slowing down may contribute to the development of PTG in this population. Future research should quantitatively investigate the trajectory of PTG for PWA, assess interventions that may facilitate PTG, and examine how PTG contributes to overall recovery.

This study examined how different background noise conditions affected the spoken language production of people with aphasia (PWA) when performing a story retell task. Participants included 11 adults with mild to moderate aphasia and 11 age- and gender-matched controls. Participants retold stories in a silent baseline and five background noise conditions (conversation, monologue, phone call, cocktail, pink noise). Dependent measures of speech fluency and language production measures (correct information units, lexical errors, lexical diversity, and cohesive utterances) were compared between groups and across conditions. Results reveal that background noise results in significantly lower communication efficiency (i.e., correct information units) for the aphasic group than the control group. PWA also experience background noise costs in relation to speech fluency and lexical production during both conversation and phone call conditions. The control group experience no significant background noise costs. These findings suggest that background noise interferes with discourse more for PWA than neurologically healthy adults.

There has been limited research done in the Philippines in the area of aphasia, a frequent concomitant symptom of strokes and presents as impairment in any area of the input and output of language. Diagnosis is generally conducted by clinicians based on sites of lesion of speakers with aphasia and clinical observations of language symptoms and unpublished translation of the WAB. The lack of relevant research and formal assessment tools in the Philippines motivated this current study. The development of this type of assessment battery for the Tagalog (pronounced /təˈɡɑːlɒɡ/ in English) speaking population will provide a means for differential diagnosis of acquired neurogenic communication disorders. The goal of this study is to develop a Tagalog version of the Western Aphasia Battery – Revised (WAB-R; Kertesz, 2006). The WAB-R was chosen as the basis for the development of the T-WAB-R due to the researched, validated and standardized nature of the battery for use with assessing the severity and type of aphasia through score profiles. This battery provides clinicians with a comprehensive evaluation of language skills in English and is projected to do the same in Tagalog. Given the lack of normative data on the Tagalog speaking population on this test, the current study establishes the normative data of the T-WAB-R from native speakers of Tagalog, encompassing external factors of gender (e.g. male and female) and stratified into three age groups (e.g., 20-39; 40-60; 61+ years old). A full-scale development of the battery will provide a means for differential diagnosis of acquired neurogenic communication disorders in the Tagalogspeaking population.

ABSTRACT In the context of increasing incidence of stroke (but also an increasing rate of survival), non-invasive brain stimulation techniques (NIBS) are more frequently used for patients with post-stroke aphasia (PWA) and post-stroke depression (PSD). NIBS techniques, modulating brain plasticity, might offer valid, alternative therapeutic strategies. The aim is to reach a better outcome because treatment of aphasia can also improve post-stroke depression and vice versa. Based on two literature reviews on NIBS effects on PSD and post-stroke aphasia the conclusion is that, although the field is relatively new, and many more investigations with larger samples of patients are required, transcranial magnetic stimulation (TMS) and transcranial direct current stimulation (tDCS) clinical application is well tolerated, safe, and feasible. Starting from these encouraging data, we used a combination of TMS and electroencephalography (EEG) to explore the excitability modulation before and after active (20 sessions) and sham (20 sessions) tDCS in a double-blind crossover experiment. Four chronic non fluent PWA underwent 8 weeks of verbal exercises coupled with tDCS over the perilesional areas close to the left inferior frontal gyrus. To evaluate changes induced by tDCS, TMS-EEG responses over Brodmann area 6 (BA6) were computed using five different parameters. In addition, these data were compared with those recorded from a matched control group. The results indicated a slight improvement after tDCS stimulation (as compared to sham) for patients with Broca’s aphasia, but not for those with global aphasia. Also, TMS-evoked EEG responses recorded from the ipsilesional hemisphere were abnormal in individuals with chronic post-stroke aphasia (slower and simple responses with higher amplitudes) when compared to responses from the contralesional hemisphere and from the control group. Critically, the Global Mean Field Power (GMFP), Local Mean Field Power (LMFP) and Natural Frequency values were modulated by anodal tDCS. Despite these interesting results, further data are needed in order the obtain more direct, stronger evidence linking behavioral tDCS effects and neurophysiological data.
