Primary progressive aphasia is a clinical syndrome defined by progressive deficits isolated to speech and/or language, and can be classified into non-fluent, semantic and logopenic variants based on motor speech, linguistic and cognitive features. The connected speech of patients with primary progressive aphasia has often been dichotomized simply as 'fluent' or 'non-fluent', however fluency is ...

Background: Aphasia is a common outcome of Cerebrovascular Accident (CVA) in which clinical interventions have limited effectiveness. Some evidence suggests that noninvasive stimulation of the brain can have beneficial effects in the treatment of CVA induced aphasia. In patients with motor aphasia, repetitive Transcranial Magnetic Stimulation (rTMS) is used to facilitate long-term improvement i...

Word-retrieval treatment studies in aphasia have reported the greatest influences on picture naming for trained words. To increase treatment effects to untrained words and sentence contexts, we investigated a sentence-reading treatment hierarchy that moves from errorless to generative production of sentences incorporating target nouns and verbs. In an individual with nonfluent aphasia, treatmen...

Fluent primary progressive aphasia (fPPA) is very often confused with semantic dementia (SD), due to the ambiguity of the latter term. We present a case of fPPA with neuropsychological and neuroimaing data, not fulfilling the diagnostic criteria for SD. The language disturbance profile is presented, resembling transcortical sensory aphasia. The results of both standardized and experimental test...

Background The aphasiological literature has traditionally distinguished between anterior aphasia, associated with non-fluent speech, characterized by phonetic distortions arising from a disruption at the motor level of encoding, and posterior aphasia, characterized by fluent speech with phonological errors, due to a deficit at a higher level. However, these studies focused predominantly on con...
