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.

ABSTRACTWe have compared the verbal comprehension abilities of 34 right hemisphere damaged patients to 16 hospitalized control subjects of comparable age and educational attainment. The right hemisphere damaged patients performed as well as the control subjects on a vocabulary test, but were impaired in their ability to interpret proverbs and comprehend logico-grammatical sentences. Impairment on the proverbs test was the result of a decrease in the number of abstract interpretations, whereas impairment on the logico-grammatical sentence comprehension test was related to difficultes in grasping spatial and passive relationships. These comprehension impairments tended to correlate with visuospatial deficits and hemianopia, but not with the degree of hemiparesis or the presence of sensory extinction. Patients with anterior right hemisphere damage performed better on the logico-grammatical sentence conprehension test than patients with posterior damage. A variety of factors probably contribute to these verbal deficits including impaired intellect, inattention, an inability to grasp spatial relationships, and difficulties in manipulating the inner schemata of language.

Objective To investigate somatosensory deficits in the ipsilesional wrist and hand in chronic stroke patients and correlate these deficits with contralesional sensorimotor dysfunctions, functional testing, laterality and handedness.Methods Fifty subjects (twenty-two healthy volunteers and twenty-eight stroke patients) underwent evaluation with Semmes-Weinstein monofilaments, the sensory and motor Fugl-Meyer Assessment, the Nottingham Sensory Assessment in both wrists and hands and functional tests.Results Twenty-five patients had sensory changes in the wrist and hand contralateral to the stroke, and eighteen patients (64%) had sensory deficits in the ipsilesional wrist and hand. The most significant ipsilesional sensory loss was observed in the left-handed patients. We found that the patients with brain damage in the right hemisphere had better scores for ipsilesional tactile sensation.Conclusions A reduction in ipsilesional conscious proprioception, tactile or thermal sensation was found in stroke subjects. Right hemisphere damage and right-handed subjects had better scores in ipsilesional tactile sensation.

✓ In the past two to three decades, clinicians and neuroscientists have been studying the functions of the right hemisphere. Neither hemisphere seems to be dominant in the absolute sense. Each appears to be specialized and is dominant for different functions. However, most functions require the cooperation of both hemispheres. When one is damaged, the other can often compensate for the damaged one. Lesions of the left hemisphere are associated with language (speech, reading, and writing) and praxic disorders, and lesions of the right hemisphere can result in visuospatial, attentional, and emotional disorders. The authors review some of the major behavioral disorders associated with right hemisphere dysfunction and concentrate on three major types of disorders — visuospatial, attentional, and emotional. Although not all the behavioral defects associated with right hemisphere damage can be subgrouped under these three types, they are the ones most often associated with right hemisphere lesions.

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.

In callosotomy patients, the right hemisphere attends to the entire visual field, whereas the left hemisphere attends to the right field only. The occurence of rightward attentional biases, simulating a hemineglect from right hemisphere damage, suggests that in these patients visuospatial attention tends to be controlled by the left hemisphere.

AbstractThe study aimed at investigating lateralization effects and signs of transfer and crowding in children with congenital lateralized brain damage with the aid of a dichotic listening test, a chimeric test, and verbal and nonverbal neuropsychological tests. Thirty-three children with spastic hemiplegia and 86 control children (age 5.0–12.0 yr) were assessed. Children with left-hemisphere damage (n = 17) were found to have a pathological left-ear advantage for verbal material, and children with right-hemisphere damage (n = 16) were found to have a pathological right visual half-field advantage for visual material. Children with left-hemisphere damage and a left-ear advantage on the dichotic test were also found to have a right visual half-field advantage on the chimeric test, which was regarded as a sign of reversed dominance. No verbal or nonverbal differences emerged between the left-hemisphere and the right-hemisphere damage groups, nor did differences emerge when the children were reclassified by considering children with left-hemisphere damage and signs of reversed dominance as having damage to the nondominant hemisphere. It was concluded that although lateralized brain damage may alter the dominance for verbal and visual functions, there is still considerable inter-individual variability with respect to inter- and intrahemispheric neural adjustment to damage. The dichotic and the chimeric tests did not indicate the presence of brain damage accurately, but they indicated the lateralization of damage in children with stated abnormality with a high degree (91.3%) of accuracy.

ABSTRACTComprehension of six dimensional adjectives was found to be intact in groups of left hemisphere-damaged, right hemisphere-damaged and neurologically normal patients. Phrases with those adjectives were interpreted quite differently by left hemisphere-damaged patients than by the other two groups, and a subgroup of left-damaged patients appeared to be responsible for that group's deviant responses to phrases such as slightly bigger. All patients in the left-damaged group had some difficulty with negative phrases such as not big, however. Patients with right hemisphere-damage had difficulty interpreting only negative phrases with small. Results are interpreted with reference to Luria's discussion of semantic aphasia, and with regard to recent findings concerning the role of the right hemisphere in language comprehension.

Insight Into

We know little about the neurologic bases of art production. The idea that the right brain hemisphere is the “artistic brain” is widely held, despite the lack of evidence for this claim. Artists with brain damage can offer insight into these laterality questions. The authors used an instrument called the Assessment of Art Attributes to examine the work of two individuals with left-brain damage and one with right-hemisphere damage. In each case, their art became more abstract and distorted and less realistic. They also painted with looser strokes, less depth and more vibrant colors. No unique pattern was observed following right-brain damage. However, art produced after left-brain damage also became more symbolic. These results show that the neural basis of art production is distributed across both hemispheres in the human brain.

Abstract Purpose: This article introduces two types of prosody in human communication; describes right hemisphere contributions to prosody; describes prosodic deficits associated with right hemisphere damage; and discusses prevalence, quality of life, spontaneous recovery, and treatment of aprosodia. Method: Definitions of affective and linguistic prosody and aprosodia are provided. Results of lesion studies and neuroimaging studies are reviewed to inform the reader of the importance of the right hemisphere in prosody expression and comprehension, as well as to describe patterns of prosodic deficits in individuals with right hemisphere damage. Results and Conclusions: There is a large body of evidence supporting the role of the right hemisphere in affective prosody comprehension and production. Specifically, frontal brain regions and the basal ganglia are associated with aprosodia, suggesting there may be an underlying motor impairment. Because aprosodia is enduring and can impact quality of life, it is important to gain a better understanding of this disorder so that clinicians can accurately diagnose prosodic deficits and provide informed treatment.
