Purpose: Neurogenic speech and language disorders--such as acquired apraxia of speech (AOS) and aphasia with phonemic paraphasia (APP)--are often misdiagnosed due to similarities in clinical presentation. Word syllable duration (WSD)--a measure of average syllable length in multisyllabic words--serves as a proxy for speech rate, which is an…

Purpose: Limited research exists assessing speech perception in school-age children with speech sound disorder (SSD) and childhood apraxia of speech (CAS); despite early evidence that speech perception may lead to error-prone motor planning/programming. In this study, we examine speech perception performance in school-age children with and without…

Purpose: Speech--Music Therapy for Aphasia (SMTA), a method that combines speech therapy and music therapy, is introduced as a treatment method for childhood apraxia of speech (CAS). SMTA will be evaluated in a proof-ofprinciple study. The first case study is presented herein. Method: SMTA was evaluated in a study with a single-subject…

Background: The term progressive apraxia of speech (PAOS) is used to describe speakers presenting with isolated or dominant apraxia of speech in the context of a neurodegenerative syndrome, including primary progressive apraxia of speech (PPAOS) and dominant progressive apraxia of speech (DAOS), respectively. Its motor speech profile has been…

Purpose: The dual-task paradigm has been frequently used to examine stroke-related deficits because it samples behavioral performance under conditions of distraction similar to functioning in real-life environments. This original systematic review synthesizes studies that examined dual-task effects involving spoken language production in adults…

Background: To date, studies have not explored whether a dual diagnosis of aphasia plus apraxia of speech (AOS) versus aphasia alone (APH) affects the response to language-based naming treatments. Aims: To compare the effects of semantic feature analysis (SFA) treatment for individuals with APH versus aphasia plus AOS, and to test if the presence…

Purpose: The StartReact effect, whereby movements are elicited by loud, startling acoustic stimuli (SAS), allows the evaluation of movements when initiated through involuntary circuitry, before auditory feedback. When StartReact is applied during poststroke upper extremity movements, individuals exhibit increased muscle recruitment, reaction…

Background & aims: Echolalia, the repetition of one's or others' utterances, is a behavior present in typical development, autism spectrum disorder, aphasias, Tourette's, and other clinical groups. Despite the broad range of conditions in which echolalia can occur, it is considered primarily through a disorder-specific lens, which limits a…

Purpose: Individuals with primary progressive apraxia of speech (PPAOS) have apraxia of speech (AOS) in which disruptions in articulation or prosody predominate the speech pattern, referred to, respectively, as phonetic or prosodic subtypes. Many develop aphasia and/or dysarthria. Past research has demonstrated that simple temporal acoustic…

The statistical information that estimates the magnitude of communication disorders among Egyptian children is scarce. At Mansoura University, a prospective study was performed to identify communication disorders among nursery school children in Dakahlia governorate, Egypt to estimate the problem's size among Arabic-speaking Egyptian children…

Purpose: Of the three currently recognized variants of primary progressive aphasia, behavioral differentiation between the nonfluent/agrammatic (nfvPPA) and logopenic (lvPPA) variants is particularly difficult. The challenge includes uncertainty regarding diagnosis of apraxia of speech, which is subsumed within criteria for variant classification.…
