The Company Prosodic Deficits Keep Following Right Hemisphere Stroke: A Systematic Review, Shannon M. Sheppard, Melissa D. Stockbridge, Lynsey M. Keator, Laura L. Murray, Margaret Lehman Blake

Communication Sciences and Disorders Faculty Articles and Research

Objectives:

The aim of this systematic review was to identify the presence and nature of relationships between specific forms of aprosodia (i.e., expressive and receptive emotional and linguistic prosodic deficits) and other cognitive-communication deficits and disorders in individuals with right hemisphere damage (RHD) due to stroke.

Methods:

One hundred and ninety articles from 1970 to February 2020 investigating receptive and expressive prosody in patients with relatively focal right hemisphere brain damage were identified via database searches.

Results:

Fourteen articles were identified that met inclusion criteria, passed quality reviews, and included sufficient information about prosody and potential co-occurring …

Lesion Loci Of Impaired Affective Prosody: A Systematic Review Of Evidence From Stroke, Alexandra Zezinka Durfee, Shannon M. Sheppard, Margaret L. Blake, Argye E. Hillis

Communication Sciences and Disorders Faculty Articles and Research

Affective prosody, or the changes in rate, rhythm, pitch, and loudness that convey emotion, has long been implicated as a function of the right hemisphere (RH), yet there is a dearth of literature identifying the specific neural regions associated with its processing. The current systematic review aimed to evaluate the evidence on affective prosody localization in the RH. One hundred and ninety articles from 1970 to February 2020 investigating affective prosody comprehension and production in patients with focal brain damage were identified via database searches. Eleven articles met inclusion criteria, passed quality reviews, and were analyzed for affective prosody localization. …

Neural Regions Underlying Object And Action Naming: Complementary Evidence From Acute Stroke And Primary Progressive Aphasia, Bonnie L. Breining, Andreia V. Feria, Brian Caffo, Erin L. Meier, Shannon M. Sheppard, Rajani Sebastian, Donna C. Tippett, Argye E. Hillis

Background: Naming impairment is commonly noted in individuals with aphasia. However, object naming receives more attention than action naming. Furthermore, most studies include participants with aphasia due to only one aetiology, commonly stroke. We developed a new assessment, the Hopkins Action Naming Assessment (HANA), to evaluate action naming impairments.

Methods >& Procedures: Participants (N = 138 PPA, N = 37 acute stroke) completed the BNT and HANA. Behavioural performance was compared. A subset of participants (N = 31 PPA, N = 37 acute stroke) provided neuroimaging data. The whole brain was automatically segmented into regions of interest (ROIs). …

Characterizing Subtypes And Neural Correlates Of Receptive Aprosodia In Acute Right Hemisphere Stroke, Shannon M. Sheppard, Erin L. Meier, Alexandra Zezinka Durfee, Alex Walker, Jennifer Shea, Argye E. Hillis

Communication Sciences and Disorders Faculty Articles and Research

Introduction: Speakers naturally produce prosodic variations depending on their emotional state. Receptive prosody has several processing stages. We aimed to conduct lesion-symptom mapping to determine whether damage (core infarct or hypoperfusion) to specific brain areas was associated with receptive aprosodia or with impairment at different processing stages in individuals with acute right hemisphere stroke. We also aimed to determine whether different subtypes of receptive aprosodia exist that are characterized by distinctive behavioral performance patterns.

Methods: Twenty patients with receptive aprosodia following right hemisphere ischemic stroke were enrolled within five days of stroke; clinical imaging was acquired. Participants completed …

Diagnosing And Managing Post-Stroke Aphasia, Shannon M. Sheppard, Rajani Sebastian

Communication Sciences and Disorders Faculty Articles and Research

Introduction: Aphasia is a debilitating language disorder and even mild forms of aphasia can negatively affect functional outcomes, mood, quality of life, social participation, and the ability to return to work. Language deficits after post-stroke aphasia are heterogeneous.

Areas covered: The first part of this manuscript reviews the traditional syndrome-based classification approach as well as recent advances in aphasia classification that incorporate automatic speech recognition for aphasia classification. The second part of this manuscript reviews the behavioral approaches to aphasia treatment and recent advances such as noninvasive brain stimulation techniques and pharmacotherapy options to augment the effectiveness of …
