Age Effects on Cortical Thickness in Cognitively Normal Elderly Individuals
BACKGROUND/AIMS Atrophy in both grey and white matter is found in normal aging. The prefrontal cortex and the frontal lobe white matter are thought to be the most affected regions. Our aim was to examine the effects of normal aging on cortical grey matter using a 3D quantitative cortical mapping method. METHODS We analyzed 1.5-tesla brain magnetic resonance imaging data from 44 cognitively no...
متن کاملCortical thickness is associated with altered autonomic function in cognitively impaired and non-impaired older adults.
KEY POINTS The parasympathetic nervous system (PNS) is critical for adaptation to environment demands. Alzheimer's disease (AD), via frontal compensatory processes, may affect PNS regulation, thereby compromising older adults' capacity for adaptation, and increasing morbidity and mortality risk. Here we found that AD-associated neurodegeneration accompanied an overactive anterior cingulate cort...
متن کاملObstructive sleep apnea and cortical thickness in females and males
INTRODUCTION Obstructive sleep apnea (OSA) affects approximately 10% of adults, and alters brain gray and white matter. Psychological and physiological symptoms of the disorder are sex-specific, perhaps related to greater injury occurs in female than male patients in white matter. Our objective was to identify influences of OSA separated by sex on cortical gray matter. METHODS We assessed cor...
متن کاملSpecific anatomic associations between white matter integrity and cognitive reserve in normal and cognitively impaired elders.
OBJECTIVES to investigate the associations between white matter (WM) integrity and cognitive reserve (CR) in healthy elders (HE), amnestic mild cognitive impairment (a-MCI), and Alzheimer's disease (AD). The authors studied correlations between CR and WM integrity in regions showing WM age-related effects or pathologic changes and tested the differences of slopes between groups. METHODS diffu...
متن کاملTo rise and to fall: functional connectivity in cognitively normal and cognitively impaired patients with Parkinson's disease.
Cognitive decline is a burdensome extra-motor symptom associated with Parkinson's disease (PD). This study aimed at investigating intrinsic functional connectivity (iFC) of the brain in cognitively unimpaired (PD-CU) and impaired PD patients (PD-CI) compared with age-matched healthy controls. "Resting-state" functional magnetic resonance imaging was acquired in 53 subjects, that is, 14 PD-CU pa...
