Midlife measurements of white matter microstructure predict subsequent regional white matter atrophy in healthy adults.
OBJECTIVES Although age-related brain changes are becoming better understood, midlife patterns of change are still in need of characterization, and longitudinal studies are lacking. The aim of this study was to determine if baseline fractional anisotropy (FA), obtained from diffusion tensor imaging (DTI) predicts volume change over a 4-year interval. EXPERIMENTAL DESIGN Forty-four cognitively...
متن کاملCSF T-Tau/Aβ42 Predicts White Matter Microstructure in Healthy Adults at Risk for Alzheimer’s Disease
Cerebrospinal fluid (CSF) biomarkers T-Tau and Aβ(42) are linked with Alzheimer's disease (AD), yet little is known about the relationship between CSF biomarkers and structural brain alteration in healthy adults. In this study we examined the extent to which AD biomarkers measured in CSF predict brain microstructure indexed by diffusion tensor imaging (DTI) and volume indexed by T1-weighted ima...
متن کاملEffects of APOE on brain white matter microstructure in healthy adults.
OBJECTIVES APOE is related to cholesterol transport and clearance and brain white matter (WM) properties involving myelin, of which cholesterol is a major component. Diffusion tensor imaging enables in vivo investigations of brain WM, and could increase our understanding of the pathways leading to Alzheimer disease. The main objective was to investigate the association between APOE and diffusio...
متن کاملNeurological Soft Signs in First -Episode Schizophrenia
Neurological soft signs (NSS) refer to subtle neurological abnormalities comprising deficits in sensory integration, motor coordination, or sequencing of complex motor acts. It is generally accepted that NSS are more prevalent in schizophrenia patients, including first -episode cases, than in healthy subjects. Moreover, NSS have been consistently demonstrated in neuroleptic naïve firstepisode p...
متن کاملNeurological soft signs in obsessive-compulsive disorder.
BACKGROUND Neurological soft signs (NSSs) are defined as abnormal motor or sensory findings, including involuntary movements, a variety of dispraxia, difficulties in performing rapid alternating movements, difficulties in two-point discrimination, and graphesthesia in a person without a neurological disorder which can be determined as its focus. AIMS to investigate the relationship of NSSs wi...
