Foreign accent syndrome as a developmental motor speech disorder

Intonation in neurogenic foreign accent syndrome

“…These are common in apraxia of speech (Kent & Rosenbek, 1982, 1983. Although there was no clear indication of the presence of apraxia in the current FAS group, this possibility should be considered nonetheless, given the reported association of FAS with features of apraxia of speech (Ackermann, Hertrich, & Ziegler, 1993;Coelho & Robb, 2001;Mariën et al, 2006Mariën et al, , 2009Miller et al, 2006;Varley & Whiteside, 2001;Whiteside & Varley, 1998).…”

“…In most reported cases, the emergence of the foreign accent in speech is the result of structural brain damage, predominantly vascular brain lesions. Often, but not exclusively, these affect the cortical motor speech regions of the left hemisphere, including the prerolandic motor cortex, the frontal motor association cortex or the striatum (Kurowski, Blumstein & Alexander, 1996;Mariën et al, 2006;Mariën, Verhoeven, Wackenier & Engelborghs, 2009). …”

Neurogenic foreign accent syndrome: Articulatory setting, segments and prosody in a Dutch speaker

“…The most recent research further indicates that the cerebellum may also be crucially implicated in the development of FAS particularly in Mariën, Verhoeven, Engelborghs, Rooker, Pickut, & De Deyn (2006), Mariën & Verhoeven (2007) and Cohen, Kurowski, Steven, Blumstein, & Pascual-Leone (2009). Besides an acquired type of neurogenic FAS, a developmental variant has recently been identified by Mariën, Verhoeven, Wackenier, Engelborghs, & De Deyn (2009) who described FAS in the context of developmental apraxia of speech and specific language impairment.…”

Foreign Accent Syndrome Secondary to Medication Withdrawal: A Case Report

“…10,[18][19][20] Due to the variety of etiologies and lack of common features, it has been suggested that FAS is not the result of any single underlying mechanism. 7 A few cases of FAS have been reported in the literature secondary to psychogenic, rather than neurogenic causes.…”
