Abstract

Word retrieval deficit is found to be one of the most persistent symptoms reported among the constellation of symptoms exhibited by persons with aphasia (PWAs). This deficit restraints the persons with aphasia to perform with ease across day-to-day conversations. As a consequence, PWAs fail to communicate their desired ideas or thoughts. Word retrieval is an intricate process as it entails various levels of processing. In addition, word retrieval breakdown can occur at multiple levels (semantic level or lexical-semantic level, or phonological level). Thus, there is a need for speech-language pathologists (SLPs) to treat this deficit through effective treatment approaches. In recent decades, semantic feature analysis, verb network strengthening treatment, and phonological component analysis have received greater focus and importance in treating word retrieval deficits. Many studies confirmed that the use of these treatment approaches on PWAs possesses a pivotal role in remediating word retrieval deficits.

Highlights

  • Word retrieval deficits remain one of the enduring symptoms in most persons with aphasia (PWAs) [1]

  • The prevailing literature on word retrieval failures suggests that this deficit varies in their cognitive and neural underpinnings among discrete variants of aphasia

  • The speech-language pathologists (SLPs) treating word retrieval deficits firstly needs to understand the nature of word retrieval breakdown

Summary

Introduction

Word retrieval deficits remain one of the enduring symptoms in most PWAs [1]. Word retrieval deficits are events where the individual exhibits word-finding difficulty in conversation or while conveying their ideas or thoughts. The prevailing literature on word retrieval failures suggests that this deficit varies in their cognitive and neural underpinnings among discrete variants of aphasia. The SLP treating word retrieval deficits firstly needs to understand the nature of word retrieval breakdown (semantic or phonemic). These are ascertained via comprehensive naming assessments, and based on the nature of word retrieval failures, appropriate treatment paradigms need to be employed
