The lack of standardized instruments to evaluate communication disorders related to the right hemisphere was verified. A new evaluation tool was developed: Protocole Montréal d'Évaluation de la Communication – Protocole MEC, adapted to Brazilian Portuguese – Bateria Montreal de Avaliação da Comunicação – Bateria MAC (Montreal Evaluation of Communication Battery). The purpose was to present stratified normative data by age and educational level, and to verify the reliability parameters of the MEC Battery. 300 individuals, between the ages of 19 and 75 years, and levels of formal education between 2 and 35 years, participated in this study. They were divided equally into six normative groups, according to three age categories (young adults, intermediary age, and seniors) and two educational levels (low and high). Two procedures were used to check reliability: Cronbach alpha and reliability between evaluators. Results were established at the 10th percentile, and an alert point per task for each normative group. Cronbach's alpha was, in general, between .70 and .90 and the average rate of agreement between evaluators varied from .62 to .94. Standards of age and education were established. The reliability of this instrument was verified. The psychometric legitimization of the MEC Battery will contribute to the diagnostic process for communicative disorders.

Abstract Objective Arteriovenous malformations (AVMs) are tangled masses of arteries and veins of congenital origin. AVMs are rare (~4.3% in the general population) and symptomatic cases are rarer still (0.1–1%). AVMs account for strokes in 1–2% of cases. We present the case of a 59-year-old, right-handed, Caucasian male, with nine years of formal education, who was evaluated as an inpatient following a ruptured AVM. Method Patient with known history of AVM (Figure 1) presented with headache and new onset seizure. Computerized tomography (CT) revealed rupture of an AVM at the right temporal-occipital junction, with resulting intraparenchymal hemorrhage within the right parieto-occipital lobe and the right ventricular system and 0.8 cm left midline shift (Figure 2). The patient underwent emergency craniotomy for evacuation of intracerebral hematoma, resection of AVM, and placement of right external ventricular drain (EVD). Electroencephalograom (EEG) revealed focal cortical dysfunction over the right hemisphere and moderate encephalopathy. Results (Table 1). Neuropsychological evaluation six days following emergency craniotomy revealed primary impairment in visuoperceptual and visuoconstructional skills (including left neglect; Figures 3 & 4), impairments in working memory, learning/memory of verbal information (with intact recognition), as well as impairment in aspects of language (semantic fluency). These were accompanied by dense anosagnosia pertaining to cognitive deficits, but intact insight related to his hospitalization. Conclusions This is a rare case of symptomatic AVM with neuropsychological evaluation data highlighting the associated evolving cognitive (e.g., left neglect and visuoperceptual disturbance) and neuropsychiatric deficits (e.g., dense anosagnosia) in the context of recent neurosurgical interventions (e.g., evacuation of hemorrhage, placement of EVD, etc.).

Clinical Awareness

It is now consensually accepted that the contribution of both hemispheres is required to reach a functional level of communication. The unilateralized view of language function, introduced more than a century ago, has since been complemented by clinical experience as well as neuro-imaging observations. Studies based on healthy and right-brain-damaged individuals assert the necessity to better describe, assess, and care for this broad population. Indeed, various neurological conditions, including stroke, traumatic brain injury (TBI), or neurodegenerative disease, can affect the right hemisphere (RH) and lead to distinct communication disorders. In the past 30 years, knowledge about communication assessment and, more recently, therapy designed for right-brain-damaged adults has drastically evolved. This manuscript aims at presenting the theoretical and clinical background that established the current expertise to support accurate assessment of communication following right brain damage. It is believed that a better understanding of the various profiles of impairments following a RH infract will allow speech-language pathologists (SLPs) to develop the clinical awareness necessary for appropriately taking care of these individuals.

Verbal Output

Neurologic damage affecting the left cerebral hemisphere leads to impairments in comprehension and expression of language in the verbal modality (aphasia) and in the written modality (dyslexia and dysgraphia). Impairment patterns take various forms, differing in the fluency/nonfluency of verbal output and integrity of auditory comprehension, repetition, and word retrieval abilities. The divergent classifications of aphasia allow reflection on neural and psychological correlates of specific aspects of language processing in verbal and written modalities. Neurologic damage affecting the right cerebral hemisphere can lead to changes in social and prosodic communication, speaking to the role of the right hemisphere in language processing. Patterns of language breakdown following neurologic injury have implications for assessment and intervention for affected individuals. Whereas perspectives vary on interpretation of the language breakdown across disciplines, this volume’s purpose is to facilitate interactions across disciplines to improve the lives of those with aphasia and related communication disorders.

Abstract Cluttering is discussed openly in the fluency literature, but few educational opportunities for learning more about cluttering exist in higher education. The purpose of this manuscript is to explain how a seminar in cluttering was developed for a group of communication disorders doctoral students. The major theoretical issues, educational questions, and conclusions are discussed.

The combined interactions of mode and tempo on emotional responses to music were investigated using both self-reports and electroencephalogram (EEG) activity. A musical excerpt was performed in three different modes and tempi. Participants rated the emotional content of the resulting nine stimuli and their EEG activity was recorded. Musical modes influence the valence of emotion with major mode being evaluated happier and more serene, than minor and locrian modes. In EEG frontal activity, major mode was associated with an increased alpha activation in the left hemisphere compared to minor and locrian modes, which, in turn, induced increased activation in the right hemisphere. The tempo modulates the arousal value of emotion with faster tempi associated with stronger feeling of happiness and anger and this effect is associated in EEG with an increase of frontal activation in the left hemisphere. By contrast, slow tempo induced decreased frontal activation in the left hemisphere. Some interactive effects were found between mode and tempo: An increase of tempo modulated the emotion differently depending on the mode of the piece.

Hemisphere Specialization

Previous studies often revealed a right-hemisphere specialization for processing the global level of compound visual stimuli. Here we explore whether a similar specialization exists for the detection of intersected contours defined by a chain of local elements. Subjects were presented with arrays of randomly oriented Gabor patches that could contain a global path of collinearly arranged elements in the left or in the right visual hemifield. As expected, the detection accuracy was higher for contours presented to the left visual field/right hemisphere. This difference was absent in two control conditions where the smoothness of the contour was decreased. The results demonstrate that the contour detection, often considered to be driven by lateral coactivation in primary visual cortex, relies on higher-level visual representations that differ between the hemispheres. Furthermore, because contour and non-contour stimuli had the same spatial frequency spectra, the results challenge the view that the right-hemisphere advantage in global processing depends on a specialization for processing low spatial frequencies.
