“…Defective semantic processing skills have been shown to be associated with more indefinite and amorphous gestures (Hadar, Wenkert-Olenik, Krauss, & Soroker, 1998) and with reductions of spatial and kinetic diversity of hand gestures (Hogrefe et al, 2012). Additionally, these skills have been shown to be a prerequisite of a successful functional communication in speakers who have aphasia (Fucetola et al, 2006).…”

Background: Two main conflicting positions exist concerning the relationship of gesture and speech. The first claims that gesture and speech constitute a single bimodal production process that leads to an impairment of both communication channels in the case of aphasia. The second accounts for two independent but tightly coordinated processes with a trade-off relationship of gesture and speech. According to the latter assumption, speakers who have aphasia should be able to compensate for their verbal deficiencies through gesture. Studies provide evidence for both accounts. Furthermore, non-verbal capacities like semantic processing or manual praxis have been shown to influence the gestural performance of speakers who have aphasia. Aims: The first aim of the current study was to clarify the relationship between gesture and speech production in aphasia by exploring how much information speakers with aphasia conveyed by gesture versus speech in narrations. The second aim was to evaluate if these speakers make use of their full communicative potential through gesture. We compared gesture use in a verbal narration with gesture use in a silent condition, where participants were not allowed to speak. Furthermore, the influence of language and non-verbal cognitive capacities on gesture was examined. Methods & Procedures:Sixteen participants with varying degrees of aphasia severity retold short video clips in a verbal and a silent condition. In the latter, participants were asked to retell the stories by exclusively using gestures. Subsequently, healthy speakers judged the comprehensibility of gestures and of the spoken expression in the verbal narration in a forced-choice recognition task. Comprehensibility scores were compared between conditions and influencing linguistic and non-verbal factors were evaluated. Outcomes & Results: In the verbal condition, two participants conveyed more information through gesture than through spoken expression. Furthermore, half of the participants could augment gestural comprehensibility in the silent condition. Communicative efficiency of gesture was predicted by the pantomime-to-command test.

“…The notion that impairments in non-language cognitive domains and behavior influence the clinical presentation and evolution of aphasia is gaining credence amongst aphasiologists (Kauhanen et al, 2000; Fucetola et al, 2006; van de Sandt-Koenderman et al, 2008; Lambon Ralph et al, 2010; El Hachioui et al, 2014). Since the same argument probably holds for echolalia in aphasia, we emphasize the strong necessity to explore the relationship between verbal echoing, concurrent deficits in language and high-level cognitive non-language processes, and the neural mechanisms underpinning these domains in aphasia.…”

“…Aphasia severity, receptive language deficits (semantic and reading comprehension) and depression negatively impact functional communication (Starkstein and Robinson 1988;Fucetola et al 2005a) and other stroke-related motor, cognitive and behavioral deficits additionally contribute to reduce quality of life and increase dependence on others. Two thirds of PSA patients are above 65 years of age and a proportion of them (> 10%) have cognitive deficits that precede the stroke and follow a progressive decline after the stroke onset (Mackowiak-Cordoliani et al 2005).…”

Drug Therapy of Post-Stroke Aphasia: A Review of Current Evidence

et al. 2011

This review considers the role of drug therapy in the treatment of post-stroke aphasia, the evidence for efficacy of different agents, and the theory-based explanations of drug-related benefits for aphasia rehabilitation. Pharmacological interventions modulating stroke-induced disruption of diverse neurotransmitters may improve language and communication deficits in aphasic patients through facilitation of brain plasticity and long-term potentiation. However, benefits are not evident for all compounds and refinement in clinical trial designs is required. Some pharmacological trials have failed because drug treatment was not combined with speech-language therapy, while other trials combining drugs with intensive model-driven therapies also failed probably because of short-trial duration, inadequate sample selection, or lack of drug action. Preliminary data reveals that combining neuroscience-based intensive aphasia techniques (constraint-induced aphasia therapy) and drugs acting on cholinergic and glutamatergic neurotransmitter systems are associated with better outcomes than other strategies and long-term maintenance of benefits. Although further studies are needed, current state of the evidence suggests that drug therapy may play a key role in the treatment of post-stroke aphasia.
