Anosognosia in Dementia: Evaluation of Perfusion Correlates Using 99mTc-HMPAO SPECT and Automated Brodmann Areas Analysis
(2022)(1) Background: Considerable inconsistency exists regarding the neural substrates of anosognosia in dementia in previous neuroimaging studies. The purpose of this study was the evaluation of anosognosia perfusion correlates ... -
Antidepressants influence somatostatin levels and receptor pharmacology in brain
(2009)This study investigated how the administration (acute and chronic) of the antidepressants citalopram and desmethylimipramine (DMI) influences somatostatin (somatotropin release inhibitory factor, SRIF) levels and SRIF ... -
Assessing multiple-group diagnostic problems with multi-dimensional receiver operating characteristic surfaces: Application to proton MR Spectroscopy (MRS) in HIV-related neurological injury
(2008)We present the multi-dimensional Receiver Operating Characteristic (ROC) surface, a plot of the true classification rates of tests based on levels of biological markers, for multi-group discrimination, as an extension of ... -
Differences of apathy perfusion correlates between Alzheimer’s disease and frontotemporal dementia. A 99mTc-HMPAO SPECT study with automated Brodmann areas analysis
(2022)Objectives: To explore differences of apathy perfusion correlates between Alzheimer’s disease (AD) and Frontotemporal dementia (FTD) using perfusion SPECT. Methods: We studied 75 FTD and 66 AD patients. We evaluated apathy ...
