Impaired Interoceptive Accuracy in Semantic Variant Primary Progressive Aphasia

Background Interoception (the perception of internal bodily sensations) is strongly linked to emotional experience and sensitivity to the emotions of others in healthy subjects. Interoceptive impairment may contribute to the profound socioemotional symptoms that characterize frontotemporal dementia (FTD) syndromes, but remains poorly defined. Methods Patients representing all major FTD syndro...

Flortaucipir tau PET imaging in semantic variant primary progressive aphasia.

OBJECTIVE The semantic variant of primary progressive aphasia (svPPA) is typically associated with frontotemporal lobar degeneration (FTLD) with longTAR DNA-binding protein (TDP)-43-positive neuropil threads and dystrophic neurites (type C), and is only rarely due to a primary tauopathy or Alzheimer's disease. We undertook this study to investigate the localisation and magnitude of the presumed...

Grapheme-to-Phoneme Conversion Associative Rules for K

In this paper, we describe a method for automatically extracting grapheme-to-phoneme conversion rules directly from the transcription of speech synthesis database and introduce a weighted score and jamo similarity to overcome the rule application difficulties. We make a structured rule tree by rule pruning and rule association, and can eliminate most of the rules with almost no decrease of the ...
