Cortical thinning is associated with disease stages and dementia in Parkinson's disease
Objective To investigate the pattern of cortical thinning in Parkinson's disease (PD) across different disease stages and to elucidate to what extent cortical thinning is related to cognitiveExpand

A cross-sectional and follow-up voxel-based morphometric MRI study in adolescent anorexia nervosa.
The objective was to examine whether cerebral volumes are reduced, and in what regions, in adolescents with anorexia nervosa and to study changes after nutritional recovery. Twelve anorexia nervosaExpand

Impact of the COMT Val108/158 Met and DAT genotypes on prefrontal function in healthy subjects
Two limiting factors of dopamine activity are the catechol-o-methyltransferase (COMT) and the dopamine transporter (DAT), which terminate dopamine activity by degradation and uptake, respectively.Expand

Neuroanatomical correlates of impaired decision‐making and facial emotion recognition in early Parkinson’s disease
Decision‐making and recognition of emotions are often impaired in patients with Parkinson’s disease (PD). The orbitofrontal cortex (OFC) and the amygdala are critical structures subserving theseExpand

Neuroanatomical substrate of visuospatial and visuoperceptual impairment in Parkinson's disease
To determine magnetic resonance imaging patterns of gray matter (GM) atrophy underlying visuospatial and visuoperceptual impairment in Parkinson's disease (PD), we applied voxel‐based morphometry toExpand

Cerebral atrophy in Parkinson's disease patients with visual hallucinations
Although visual hallucinations (VH) are relatively frequent in Parkinson's disease (PD) patients, their neural substrates are only known from neuropathological and functional magnetic resonanceExpand

Hippocampal head atrophy predominance in Parkinson’s disease with hallucinations and with dementia
We studied regional gray matter density in the hippocampus in Parkinson’s disease (PD) patients. We obtained magnetic resonance scans in 44 PD patients (PD patients with dementia (PDD) = 9,Expand

Sustained attention impairment correlates to gray matter decreases in first episode neuroleptic-naive schizophrenic patients
Impaired sustained attention seems to be a specific neuropsychological deficit that is closely linked to schizophrenia. Voxel based morphometry has emerged as a useful tool for the detection ofExpand

Differential progression of brain atrophy in Parkinson's disease with and without visual hallucinations
Objective To determine the course of cognitive deficits and the regional progression of brain atrophy in patients with Parkinson's disease (PD) with and without visual hallucinations (VH). MethodsExpand

The Human Cerebral Cortex Flattens during Adolescence
The human cerebral cortex appears to shrink during adolescence. To delineate the dynamic morphological changes involved in this process, 52 healthy male and female adolescents (11–17 years old) wereExpand
