We studied noun and verb naming in three main variants of frontotemporal dementia: the frontal variant(Fv-FTD), primary progressive aphasia (PPA) and semantic dementia (SD). We further distinguished PPA in nonfluent and fluent forms and restricted diagnosis of SD to subjects with progressive semantic breakdown leading to agnosia for words and objects. Fv-FTD and nonfluent-PPA named objects bett...

Objectives: Semantic Feature Analysis was designed to improve lexical retrieval of aphasic patients via activation of semantic networks of the words. In this approach, the anomic patients are cured with semantic information to assist oral naming. The purpose of this study was to examine the effects of Semantic Feature Analysis treatment on anomia of two nonfluent aphasic patients. Methods: A...

Abstract OBJECTIVE Determination of the correlation between gamma-band modulations electrocorticogram (ECoG) induced by linguistic tasks and reproducible speech arrests caused bipolar direct cortical stimulations (DCS). METHODS 3 subjects (age 39, 56, 64 years) with left temporal lobe glioma underwent surgery involving awake craniotomy. A 4x8 ECoG electrode grid (2.3mm contact exposure, 1cm spa...

BACKGROUND AND PURPOSE Although multiple studies have suggested that repetitive transcranial magnetic stimulation (rTMS) may facilitate recovery after stroke, the efficacy of synchronous speech therapy integrated with an rTMS protocol has yet to be determined. We investigated language responses to this strategy and determined the longevity of the resulting therapeutic outcomes. METHODS Forty-...

Objectives: Based on recent studies, verb naming is more impaired than noun naming in patients with Parkinson Disease (PD). Noun and verb retrieval problems has been well documented in patients with cortical damage. To explore the possible contribution of cortex and subcortex areas in word finding test performance, we studied verb and object naming in patients with cortical and subcortical lesi...
