Clinical tests and PET brain imaging help distinguish the 3 most common dementia subtypes

Mixed dementia--the most common cause of dementia.

The existence of vascular dementia (VaD) was first identified by Marie, who described the etat lacunaire, and by Binswanger, who identified white matter lesions. The role of cortical lesions, while clear to clinicians, was highlighted only later by the pathological studies of Tomlinson and the clinical demonstrations of Hachinski et al., who have defined multi-infarct dementia. Lately, the emph...

ACR-ASNR Practice Parameter for Brain PET/CT Imaging Dementia.

This practice parameter is for both FDG and amyloid brain PET or PET/computed tomography (CT) for patients with cognitive decline, and has been developed collaboratively by the American College of Radiology (ACR) and the American Society for Neuroradiology (ASNR). It is estimated that the number of people with dementia, 36.5 million worldwide in 2010, will increase to 65.7 million in 2030 and t...

Brain metabolites Associated with Common Clinical Symptoms of multiple sclerosis patients Using MagneticResonance Imaging

Introduction: Multiple Sclerosis (MS) is an auto-immune disease that involves central nervous system (CNS). Magnetic Resonance Spectroscopy (MRS) is an analytical non- invasive method for obtaining the pathologic data of disease and it brings biochemical information about studied tissue which can be helped in studying the reasons and development process of disease and it increa...

Review: most laboratory tests do not add to the diagnostic accuracy of clinical criteria for dementia.

Amyloid brain PET imaging

Brain positron emission tomography (PET) has also been used over many years to diagnose neurodegenerative diseases, and has advantages over MRI due to its higher sensitivity to detect pathologies at a molecular level. While 18F-fluorodeoxyglucose (FDG) PETCT is an established imaging technique for assisting in the differential diagnosis of Alzheimer’s disease (AD) and other forms of dementia, P...
