Anatomical correlates of early mutism in progressive nonfluent aphasia
(American Academy of Neurology, 2006)
Patients with progressive nonfluent aphasia (PNFA) can become mute early in the course of the disease. Voxel-based morphometry showed that PNFA is associated with left anterior insula and inferior frontal atrophy. In ...
Longitudinal gray matter contraction in three variants of primary progressive aphasia : a tensor-based morphometry study
The present study investigated the pattern of longitudinal changes in cognition and anatomy in three variants of primary progressive aphasia (PPA). Eight patients with the non-fluent variant of PPA (nfvPPA), 13 patients ...
Regional brain stem atrophy in idiopathic Parkinson's disease detected by anatomical MRI
(Public Library of Science, 2009-12-10)
Idiopathic Parkinson’s disease (PD) is a neurodegenerative disorder characterized by the dysfunction of dopaminergic dependent cortico-basal ganglia loops and diagnosed on the basis of motor symptoms (tremors and/or ...
Regional reductions of gray matter volume in familial dyslexia
(American Academy of Neurology, 2004)
An in vivo anatomic study of gray matter volume was performed in a group of familial dyslexic individuals, using an optimized method of voxel-based morphometry. Focal abnormalities in gray matter volume were observed bilaterally ...
The logopenic/phonological variant of primary progressive aphasia
(American Academy of Neurology, 2008)
Objective: Primary progressive aphasia (PPA) is characterized by isolated decline in language functions. Semantic dementia and progressive nonfluent aphasia are accepted PPA variants. A “logopenic” variant (LPA) has also ...
