Summary of "Executive functions in aphasia: A novel aphasia screening for cognitive flexibility in everyday communication."

Besides language deficits, persons with aphasia can present with impairments in executive functions such as cognitive flexibility. Since these impairments can restrict communicative abilities, diagnostics for aphasia should include their assessment. However, tests of executive functions, including symptoms expressed in everyday communication, are lacking for aphasia. Thus, our aim was to fill this gap and study the basic psychometric properties of the novel Cognitive Flexibility in Aphasia Screening. For a pilot evaluation, 26 German patients were examined with tests for language and cognitive flexibility as well as the novel screening. Moreover, 20 non-aphasic persons conducted the latter. We performed a Receiver Operating Characteristic analysis to investigate specificity and sensitivity, and multidimensional scaling to examine similarities between the screening and language/cognitive skills. We found good specificity and sensitivity and showed that the screening is correlated with language skills and verbal cognitive flexibility, revealing promising construct validity and feasibility of the new screening.

Medical and Biotech [MESH] Definitions

A set of cognitive functions that controls complex, goal-directed thought and behavior. Executive function involves multiple domains, such as CONCEPT FORMATION, goal management, cognitive flexibility, INHIBITION control, and WORKING MEMORY. Impaired executive function is seen in a range of disorders, e.g., SCHIZOPHRENIA; and ADHD.

A type of fluent aphasia characterized by an impaired ability to repeat one and two word phrases, despite retained comprehension. This condition is associated with dominant hemisphere lesions involving the arcuate fasciculus (a white matter projection between Broca's and Wernicke's areas) and adjacent structures. Like patients with Wernicke aphasia (APHASIA, WERNICKE), patients with conduction aphasia are fluent but commit paraphasic errors during attempts at written and oral forms of communication. (From Adams et al., Principles of Neurology, 6th ed, p482; Brain & Bannister, Clinical Neurology, 7th ed, p142; Kandel et al., Principles of Neural Science, 3d ed, p848)

A cognitive disorder marked by an impaired ability to comprehend or express language in its written or spoken form. This condition is caused by diseases which affect the language areas of the dominant hemisphere. Clinical features are used to classify the various subtypes of this condition. General categories include receptive, expressive, and mixed forms of aphasia.

A progressive form of dementia characterized by the global loss of language abilities and initial preservation of other cognitive functions. Fluent and nonfluent subtypes have been described. Eventually a pattern of global cognitive dysfunction, similar to ALZHEIMER DISEASE, emerges. Pathologically, there are no Alzheimer or PICK DISEASE like changes, however, spongiform changes of cortical layers II and III are present in the TEMPORAL LOBE and FRONTAL LOBE. (From Brain 1998 Jan;121(Pt 1):115-26)

Functional region comprising posterior part of the SUPERIOR TEMPORAL GYRUS in the dominant cerebral hemisphere (see CEREBRAL DOMINANCE) and often portions of the PARIETAL LOBE. Along with BROCA AREA it is important in SPEECH and LANGUAGE processes. A lesion in the area is associated with WERNICKE APHASIA and CONDUCTION APHASIA.
