Journal ArticleDOI
Early diagnosis of Alzheimer's disease using cortical thickness: impact of cognitive reserve.
O Querbes,O Querbes,Florent Aubry,Florent Aubry,Jérémie Pariente,Jérémie Pariente,Jean-Albert Lotterie,Jean-Albert Lotterie,Jean-François Démonet,Jean-François Démonet,Véronique Duret,Michèle Puel,Michèle Puel,Isabelle Berry,Isabelle Berry,Jean-Claude Fort,Pierre Celsis,Pierre Celsis +17 more
TL;DR: Using a normalized thickness index-based criterion may help with early diagnosis of Alzheimer's disease at the individual level, especially for highly educated subjects, up to 24 months before clinical criteria for Alzheimer's Disease diagnosis are met.
Journal ArticleDOI
Magnetic resonance imaging markers of Parkinson’s disease nigrostriatal signature
Patrice Péran,Andrea Cherubini,Francesca Assogna,Fabrizio Piras,Carlo Cosimo Quattrocchi,Antonella Peppe,Pierre Celsis,Olivier Rascol,Olivier Rascol,Jean-François Démonet,Alessandro Stefani,Mariangela Pierantozzi,Francesco E. Pontieri,Carlo Caltagirone,Gianfranco Spalletta,Umberto Sabatini +15 more
TL;DR: Parkinson-associated physiopathological modifications were characterized in six subcortical structures by simultaneously measuring quantitative magnetic resonance parameters sensitive to complementary tissue characteristics, demonstrating that multimodal magnetic resonance imaging of sub cortical grey matter structures is useful for the evaluation of Parkinson's disease and, possibly, of other subcortsical pathologies.
Journal ArticleDOI
Differential fMRI responses in the left posterior superior temporal gyrus and left supramarginal gyrus to habituation and change detection in syllables and tones.
Pierre Celsis,Kader Boulanouar,B. Doyon,Jean-Philippe Ranjeva,Isabelle Berry,Jean-Luc Nespoulous,Jean-Luc Nespoulous,François Chollet +7 more
TL;DR: The analysis of the decreases and increases in the BOLD signal across the STD, DEV, and rest conditions suggests that the left posterior superior temporal gyrus is implicated in the preattentive change detection of acoustic changes in speech as well as nonspeech stimuli, whereas the left supramarginal g Cyrus is more specifically engaged in the detection of changes in phonological units.
Journal ArticleDOI
Supplementary and Primary Sensory Motor Area Activity in Parkinson's Disease: Regional Cerebral Blood Flow Changes During Finger Movements and Effects of Apomorphine
Olivier Rascol,Umberto Sabatini,François Chollet,Pierre Celsis,Jean-Louis Montastruc,Jean-Pierre Marc-Vergnes,André Rascol +6 more
TL;DR: The hypothesis that a functional cortical motor area deafferentation is involved in the pathophysiological makeup of akinesia and that this abnormality is reversed by dopaminergic drugs is supported.
Journal ArticleDOI
Integration method of 3D MR spectroscopy into treatment planning system for glioblastoma IMRT dose painting with integrated simultaneous boost.

TL;DR: MRSI and CE abnormalities are now integrated for glioblastoma SIB-IMRT, concomitant with temozolomide, in an ongoing multi-institutional phase-III clinical trial.
