Abstract:
En este artículo reconstruyo y analizo las respuestas de los escépticos académicos a la objeción de apraxia. Esta objeción afirma que el escepticismo es una doctrina imposible de practicar puesto que sus tesis conducen a la apraxia, esta es, un estado de privación o imposibilidad de acción. Las respuestas a la objeción se dividen en dos clases. La primera prueba que el asentimiento no es una condición necesaria para realizar acciones, por lo que la recomendación escéptica de suspender global y permanentemente el asentimiento no conduciría a la apraxia. La segunda prueba que es posible deliberar y orientar racionalmente nuestras acciones sin impresiones aprehensivas, por lo que la tesis escéptica de que no existen impresiones aprehensivas tampoco conduciría a la apraxia. Tras unas breves consideraciones generales, en la primera parte de este artículo presento las respuestas de Arcesilao y en la segunda parte las repuestas de Carnéades.

Abstract:
Objective: To evaluate the predictive value of dysgraphia and constructional apraxia for delirium among psychiatric inpatients. Method: Data were collected from 2 sources. First, a series of nondelirious psychiatric inpatients that had participated in a previous study was selected to determine the specificity of various indices of dysgraphia and constructional apraxia. Second, a series of 56 psychiatric inpatients with delirium as identified using electronic administrative data and clinical records was selected to evaluate sensitivity. Results: Of the various indices of dysgraphia examined, only a global rating of writing quality and evidence of jagged or angled letter loops were informative clinical signs. The predictive value of constructional apraxia resembled the predictive value of the 2 dysgraphia indices. Conclusions: Dysgraphia and constructional apraxia are useful clinical signs of delirium in the psychiatric inpatient population. Evaluation of these functions can substantially impact diagnostic decisions where diagnostic uncertainty exists. An evaluation of writing and constructional praxis can be easily incorporated into bedside mental status examinations.

Abstract:
AbstractObjectives: Pantomiming the use of familiar tools is a central test in the assessment of apraxia. However, surprisingly, the nature of the underlying cognitive mechanisms remains an unresolved issue. The aim of this study is to shed a new light on this issue by exploring the role of functional, mechanical, and manipulation knowledge in patients with Alzheimer’s disease and semantic dementia and apraxia of tool use. Methods: We performed multiple regression analyses with the global performance and the nature of errors (i.e., production and conception) made during a pantomime of tool use task in patients and control participants as dependent variables and tasks investigating functional, mechanical, and manipulation knowledge as predictors. Results: We found that mechanical problem solving, assessing mechanical knowledge, was a good predictor of the global performance of pantomime of tool use. We also found that occurrence of conception errors was robustly predicted by the task assessing functional knowledge whereas that of production errors was not explained by only one predictor. Conclusions: Our results suggest that both functional and mechanical knowledge are important to pantomime the use of tools. To our knowledge, this is the first demonstration that mechanical knowledge plays a role in pantomime of tool use. Although impairment in pantomime of tool use tasks (i.e., apraxia) is widely explained by the disruption of manipulation knowledge, we propose that pantomime of tool use is a complex problem-solving task.

Abstract:
Introdução: A síndrome de Down (SD), trissomia do cromossomo 21, é uma condição genética que se caracteriza por um déficit cognitivo e atraso global do desenvolvimento. Dentre as habilidades que podem apresentar fragilidades, merecem destaque as alterações envolvendo a linguagem expressiva, com comprometimentos na fala. Essas alterações podem interferir no planejamento e na programação motora, caracterizando a ocorrência da apraxia de fala na infância, um distúrbio de origem neurológica, no qual a precisão e a consistência dos movimentos subjacentes à fala são prejudicadas na ausência de déficits neuromusculares. Objetivo: Apresentar a intervenção fonoaudiológica voltada à apraxia de fala em uma criança com SD. Método: O participante foi um menino com 07 anos de idade, diagnosticado com apraxia de fala associada à SD. A intervenção foi individualizada, baseada nos princípios do aprendizado motor e realizada durante 10 sessões, de 30 minutos cada. Na apresentação do caso, são abordados os dados da avaliação fonoaudiológica, os objetivos e procedimentos utilizados no planejamento terapêutico proposto. Resultados: Os dados coletados durante as sessões foram descritos e os efeitos da fonoterapia foram analisados. Os dados da reavaliação apontaram que os movimentos de praxias não verbais apresentaram melhores escores após a intervenção, sendo os resultados mais expressivos. Além disso, os resultados foram positivos quanto à estimulação para o desenvolvimento da fala, com os melhores resultados obtidos nos fonemas bilabiais /p, b e m/ e no fonema glotal /h/. Conclusão: A intervenção apresentou resultados satisfatórios, disponibilizando informações relevantes para uma melhor prática clínica na área.

Abstract:
We propose a method of orthographic visualisation strategy in a poststroke severe aphasia person with dissociation between oral and written expression. fMRI results suggest that such strategy may induce the engagement of alternative nonlanguage networks and visual representations may help improving oral output. This choice of rehabilitation method can be based on the remaining capacities and, therefore, on written language. Most notably, no study so far addressed how orthographic visualisation strategy during speech rehabilitation might influence clinical outcomes in nonfluent aphasia and apraxia patients.

Abstract:
SynopsisThe performance on four drawing tasks was studied in a sample of patients with verified Alzheimer's disease in order to examine the relationship of ‘constructional apraxia’ to neuropathological changes in the parietal lobe and in other brain areas. Twenty-three patients were able to attempt to copy pentagons, a spiral and a three-dimensional drawing of a house, 22 patients were able to draw a clock-face spontaneously. The results were rank-ordered by two independent raters. The values obtained in the different drawing tasks were correlated significantly with each other, with global estimates of cognitive performance (CAMCOG, Mini-Mental State), with a shorter duration of illness, higher brain weight (in the subsample of female patients), higher counts of large neurons in the parahippocampal gyrus and hippocampus, but not in the parietal lobe. This suggests that there is no specific relationship between ‘constructional apraxia’ and neuropathological changes in the parietal lobes of patients with advanced Alzheimer's disease, but that there is a correlation between widespread brain changes and several neuropsychological deficits, one of them being drawing disability.

Abstract:
ObjectiveTo determine the contributions of apraxia of speech (AOS) and anomia to conversational dysfluency.MethodsIn this observational study of 52 patients with chronic aphasia, 47 with concomitant AOS, fluency was quantified using correct information units per minute (CIUs/min) from propositional speech tasks. Videos of patients performing conversational, how-to and picture-description tasks, word and sentence repetition, and diadochokinetic tasks were used to diagnose AOS using the Apraxia of Speech Rating Scale (ASRS). Anomia was quantified by patients' scores on the 30 even-numbered items from the Boston Naming Test (BNT).ResultsTogether, ASRS and BNT scores accounted for 51.4% of the total variance in CIUs/min; the ASRS score accounted for the majority of that variance. The BNT score was associated with lesions in the left superior temporal gyrus, left inferior frontal gyrus, and large parts of the insula. The global ASRS score was associated with lesions in the left dorsal arcuate fasciculus (AF), pre- and post-central gyri, and both banks of the central sulcus of the insula. The ASRS score for the primary distinguishing features of AOS (no overlap with features of aphasia) was associated with less AF and more insular involvement. Only ∼27% of this apraxia-specific lesion overlapped with lesions associated with the BNT score. Lesions associated with AOS had minimal overlap with the frontal aslant tract (FAT) (<1%) or the extreme capsule fiber tract (1.4%). Finally, ASRS scores correlated significantly with damage to the insula but not to the AF, extreme capsule, or FAT.ConclusionsResults are consistent with previous findings identifying lesions of the insula and AF in patients with AOS, damage to both of which may create dysfluency in patients with aphasia.

Abstract:
Since constructional apraxia is often concomitant with brain lesions, the study of constructional tasks in the non-brain-damaged population might be useful in helping to disentangle other causal factors. This paper explores the performance of illiterate individuals (N = 29) as compared to that of semiliterates (N = 21) and literates (N = 23) in order to see the effect of reading and writing abilities on constructional tasks. Each participant was asked to construct 4 figures based upon models having varying degrees of complexity. A global criterion of lack of fidelity and several analytic criteria (related to distortion, rotation, and disarticulation errors) were used to evaluate performance. Although illiterates generally made more errors than semiliterates and semiliterates more than literates, only some of these differences were statistically significant. Significant differences were found for lack of global fidelity and disarticulation errors when all 4 figures were considered together. Subtler data emerged with respect to single figures.

Abstract:
This study examines facilitated communication as it was experienced by three people who were affected by acquired brain injury. Facilitated communication is a type of augmentative communication purported to allow persons with a severe communication impairments to communicate. The assumption is made that people with global apraxia can communicate if given physical support. The technique usually involves a facilitator providing physical support to the arm, hand or elbow of the person with the severe communication impairment to assist them to point to objects, pictures, printed letters and words or to a keyboard. Facilitated communication is a controversial method because it is difficult to establish the existence, or extent of the facilitator's influence in the communication of the person with a disability. Although much of the research on facilitated communication has been conducted with people with intellectual or developmental disabilities, research on the use of the technique with people with brain injury offers several advantages. Firstly, most people with brain injury were known to be competent communicators prior to the brain injury. Secondly, many recover sufficiently to allow a retrospective examination of the issues that faced them when they were using the technique. Thirdly, there can be a large amount of data available about the person's diagnosis, their prognosis and the course of their history following the event. Consequently, the current study uses a case study methodology to explore the application of facilitated communication with people with brain injury and draws on personal recollections of people with brain injury, interviews with families and medical and therapist reports. The three people interviewed in the study displayed varying language and memory abilities. They indicated a preference for independent communication techniques and they reported frustrations with using facilitated communication. They quickly rejected the method when speech began to appear even though their speech was inadequate for communication purposes, for two of them, for an extended period. One of the interviewees reported that facilitator influence was overwhelming at times but not always present. Two of the interviewees felt that facilitated communication gave them a start in their recovery process. Two of the interviewees reported that meaningful exchanges with others occurred only with speech. In addition to these findings the study, although not experimental, was able to shed light on some of the contentious issues surrounding facilitated communication. The method is reported to be designed to overcome the motor difficulties of the disabled communicator by providing physical assistance to individuals with poor fine motor control thus breaking the perseveration cycle that can be present . However the task of coping with facilitator influence may actually require some motor skills. Also, the physical effort involved in using facilitated communication for some individuals may have been underestimated by its supporters. However the study has shown that some individuals with severe communication impairments felt that facilitated communication had some merit but saw their ability to communicate independently as the significant achievement in their recovery.

Abstract:
The concept of communication encompasses speech and language alongside our ability to understand non-verbal communication. While communication appears effortless in normal circumstances, large amounts of unconscious processing are required from widely distributed brain regions. Non-verbal communication incorporates additional neurological systems including visual pathways, occipital lobe, mirror neurons, and so on. These observations mean that language function can be impaired from a much wider range of brain injuries than the relatively focal lesions that were traditionally considered. This chapter discusses acquired speech and language disorders (dysphasia/aphasia, fluent dysphasias, non-fluent dysphasia, global dysphasia, dysarthria, apraxia of speech, and neurogenic stuttering) and their assessment. Different therapies are defined, including impairment and communication-based therapies, and their appropriate applications depending on the underlying cause of the disorder.

Abstract:
Dementia refers to a large number of disorders characterized by global cognitive deficits, including impairments of recent memory, and one or more of the following: aphasia, apraxia, agnosia, and disturbance of executive functioning. The most common dementias are Alzheimer’s disease (AD), vascular dementia, dementia due to general medical conditions (including HIV dementia), head trauma, Parkinson’s disease (PD), Huntington’s disease, Pick’s disease, Creutzfeldt-Jakob disease, substance-induced persisting dementia, and multiple etiologies. Alzheimer’s disease, alone or in combination with other conditions (e.g., stroke), is easily the most common. With the exception of dementia associated with Parkinson’s disease, the remaining syndromes are either so rare or heterogeneous that it is difficult to find well-controlled studies that would meet diagnostic and clinical design criteria for standards defined for this book. The focus of this chapter is on therapeutic interventions for Alzheimer’s disease. Innumerable articles investigating patient populations defined as “geropsychiatric” or “gerontopsychiatric” have been excluded. Following this discussion, there is a brief review of therapeutic interventions for Parkinson’s disease.
