Structural Neuroimaging in Cognitive Impairment
Structural neuroimaging with CT or MRI in the assessment of people with cognitive impairment has traditionally been used to rule out potentially treatable/reversible causes of cognitive impairment. However, over the last decade, clinical neuroimaging has been used to rule in pathology, to refine the differential diagnosis by identifying subclinical infarcts, to quantify white matter changes and...
متن کاملStructural Neuroimaging: Brain Atrophy
Neuroimaging in Alzheimer’s disease (AD) has moved beyond the stage where it was used purely to exclude other disease processes. Structural brain magnetic resonance imaging (MRI) is useful to assess hippocampal atrophy on coronal slices; clinicians can use a simple visual rating scale, which can help to confirm the diagnosis of AD. Another useful indication for neuroimaging is to assess the con...
متن کاملBrain perfusion in polysubstance users: relationship to substance and tobacco use, cognition, and self-regulation.
BACKGROUND Brain perfusion is altered in both alcohol dependence and stimulant dependence. Although most substance users also abuse/depend on alcohol concurrently (polysubstance users; PSU), rigorous perfusion research in PSU is limited. Also, the relationships of perfusion abnormalities with cognition, impulsivity, or decision making are not well known. METHODS Arterial spin labeling MRI and...
متن کاملPrefrontal Glx and GABA concentrations and impulsivity in cigarette smokers and smoking polysubstance users.
Glutamate and GABA play an important role in substance dependence. However, it remains unclear whether this holds true for different substance use disorders and how this is related to risk-related traits such as impulsivity. We, therefore, compared Glx (as a proxy measure for glutamate) and GABA concentrations in the dorsal anterior cingulate cortex (dACC) of 48 male cigarette smokers, 61 male ...
متن کاملMetabolic abnormalities in lobar and subcortical brain regions of abstinent polysubstance users: magnetic resonance spectroscopic imaging.
AIMS The aim of the study was to explore neurometabolic and associated cognitive characteristics of patients with polysubstance use (PSU) in comparison with patients with predominant alcohol use using proton magnetic resonance spectroscopy. METHODS Brain metabolite concentrations were examined in lobar and subcortical brain regions of three age-matched groups: 1-month-abstinent alcohol-depend...
