Attention and Other Cognitive Deficits in Aphasia: Presence and Relation to Language and Communication Measures
This study was designed to further elucidate the relationship between cognition and aphasia, with a focus on attention. It was hypothesized that individuals with aphasia would display variable deficit patterns on tests of attention and other cognitive functions and that their attention deficits, particularly those of complex attention functions, would be related to their language and communication status.
A group of individuals with varying types and severity of aphasia and a group of age- and education-matched adults with no brain damage completed tests of attention, short-term and working memory, and executive functioning.
Overall, the group with aphasia performed significantly more poorly than the control group on the cognitive measures but displayed variability in the presence, types, and severity of their attention and other cognitive deficits. Correlational and regression analyses yielded significant relations between participants' attention deficits and their language and communication status.
The findings accorded well with prior research identifying (a) attention and other cognitive deficits in most but not all individuals with aphasia; (b) heterogeneity in the types and severity of attention and other cognitive symptoms among individuals with cognitive impairments; and (c) potent associations among attention, language, and other cognitive domains. Implications for clinical practice and future research are discussed.

- "It has been well established that individuals with aphasia tend to have difficulty with verbal WM (Burgio & Basso, 1997; Potagas et al., 2011) and nonverbal WM (Burgio & Basso, 1997; Lang & Quitz, 2012; Mayer & Murray, 2012; Potagas et al., 2011; Seniow, Litwin, & Lesniak, 2009; Wright & Fergadiotis, 2012) that can influence linguistic and nonlinguistic processing. Individuals with aphasia also tend to have difficulty with attention and executive function (Caspari, Parkinson, LaPointe, & Katz, 1998; Glosser & Goodglass, 1990; Hula & McNeil, 2008; Korda & Douglas, 1997; Murray, 2012a; Villard & Kiran, 2015).

The purpose of the study was to determine (1) reliability of the spatial span as a nonverbal working memory (WM) task in individuals with aphasia, (2) if participation in anomia treatment changed spatial span scores, and (3) the degree to which visuospatial WM predicted response to anomia treatment.
Eight individuals with chronic aphasia were repeatedly assessed on the forward and backward conditions of the spatial span over four weeks while undergoing treatment for anomia. Experiment 1 assessed reliability of the spatial span conditions, and determined whether span scores changed after beginning anomia treatment. Experiment 2 investigated the spatial span as a predictor of anomia treatment success.
Results of Experiment 1 showed that seven participants demonstrated stability of the forward condition of the spatial span and five participants demonstrated stability of the backward condition across all sessions (p = 0.05). No participants showed an effect of aphasia treatment on span performance in either condition. Experiment 2 found that the backward span condition significantly predicted anomia treatment effect size [F(1,6) = 15.202, p = 0.008].
Visuospatial WM abilities were highly predictive of response to anomia treatment, which supports an account of WM that includes a central processing mechanism.

- "In general, we can observe an individual profile of non-linguistic damage from which it can be deduced that it is not possible to foresee a condition of non-linguistic cognitive abilities on the basis of a condition of language abilities (Helm-Estabrooks, 2002; Seniów et al., 2009; Murray, 2012). Prevalence of non-linguistic cognitive disorders in aphasia after stroke was observed by Hachioui et al. (2014) in their study. "

ABSTRACT: Purpose: The aim of the article is to analyse cognitive disorder in persons with aphasia of various aetiology pursuant to brain damage, emphasizing the interdisciplinary cooperation between the professionals of speech therapy and psychology.Methodology: Seven persons with stroke related aphasia of different aetiology participated in the research. For data processing, psychological, neurological and speech therapeutic detailed reports were applied.Results: We observed higher incidence of ischaemic stroke than haemorrhagic stroke. Expressive aphasia occurred in 6 of the 7 clients. Attention disorder and thinking disorder occurred in almost all 6 of the clients. Executive functions were impaired in 5.Conclusion: Given our findings, we tend to aphasia therapy in terms of cognitive rehabilitation. We perceive the interdisciplinary cooperation with specialists from the field of psychology as absolutely necessary. The results of psychological examination of persons with aphasia can significantly influence the effectiveness of speech therapy intervention.

Autorka sugeruje, że chorzy z afazją wykazują trudności w zakresie planowania oraz osłabienie elastyczności poznawczej . Inni badacze dowodzą, że deficyty w zakresie przechowywania informacji semantycznych w pamięci krótkotrwałej mogą być związane z zaburzeniem funkcji wykonawczych. "

The purpose of this paper is review of research on the co-occurrence of executive dysfunction in patients with aphasia after stroke.
Aphasic speech disorders and cognitive dysfunctions are frequent consequences of the irregularities in the blood flow within the brain. Aphasia, apart from language deficits, may be accompanied by non-linguistic cognitive disorders. More and more often the co-existence of speech disorders of aphasia and the disorders of executive functions are considered. The role of executive functions is connected with the processes of planning, creating strategies, monitoring actions, self-regulation, and integration of various cognitive modalities. These activities are undoubtedly coupled with the process of speech generation. Therefore, the effective communication depends on the integrity of executive functions.
In the present paper the author has presented a survey of researches on the executive functions disorders and aphasia after stroke. In the researches the author has evaluated the level of executive functions with the application of neuropsychological methods as well as compared those results in terms of various aspects of verbal functioning, capability to communicate and conducting conversations among people with aphasia. In addition, as studies argue, the efficiency of executive functions has a significant impact on the effectiveness of aphasia rehabilitation.
