Is aging “normal”?

open access: yesAging Pathobiology and Therapeutics, 2022
The descriptive term “normal” aging is often used in scientific literature to indicate commonly occurring changes with increasing age in the absence of overt disease. However, significant molecular and geropathological changes are increasingly present to indicate there is nothing normal about aging.

Sleep in Normal Aging [PDF]

open access: yesSleep Medicine Clinics, 2018
Sleep is a key determinant of healthy and cognitive aging. Sleep patterns change with aging, independent of other factors, and include advanced sleep timing, shortened nocturnal sleep duration, increased frequency of daytime naps, increased number of nocturnal awakenings and time spent awake during the night, and decreased slow-wave sleep.

Science for the Post-Normal Age [PDF]

open access: yesCommonplace, 1993
In response to the challenges of policy issues of risk and the environment, a new type of science-‘post-normal’-is emerging. This is analysed in contrast to traditional problem-solving strategies, including core science, applied science, and professional consultancy.

Aging of the normal occlusion

open access: yesEuropean Journal of Orthodontics, 2018
The aim of this study was to evaluate the qualitative occlusal changes in individuals with normal occlusion during a period of 47 years.The sample comprised dental models of 20 subjects with normal occlusion (8 males; 12 females) taken at 13.2 years (T1) and 60.9 years of age (T2). The occlusal features were evaluated with the objective grading system (

The Myelin Water Fraction Serves as a Marker for Age-Related Myelin Alterations in the Cerebral White Matter – A Multiparametric MRI Aging Study

open access: yesFrontiers in Neuroscience, 2020
Quantitative MRI modalities, such as diffusion tensor imaging (DTI) or magnetization transfer imaging (MTI) are sensitive to the neuronal effects of aging of the cerebral white matter (WM), but lack the specificity for myelin content.

The Aging Slopes of Brain Structures Vary by Ethnicity and Sex: Evidence From a Large Magnetic Resonance Imaging Dataset From a Single Scanner of Cognitively Healthy Elderly People in Korea

open access: yesFrontiers in Aging Neuroscience, 2020
The aging of the brain is a well-investigated topic, but existing analyses have mainly focused on Caucasian samples. To investigate brain aging in East Asians, we measured cortical and subcortical volumes from magnetic resonance imaging (MRI) scans of 1 ...

Differential Age-Related Changes in Structural Covariance Networks of Human Anterior and Posterior Hippocampus

open access: yesFrontiers in Physiology, 2018
The hippocampus plays an important role in memory function relying on information interaction between distributed brain areas. The hippocampus can be divided into the anterior and posterior sections with different structure and function along its long ...

Involvement of Frontal Functions in Pain Tolerance in Aging: Evidence From Neuropsychological Assessments and Gamma-Band Oscillations

open access: yesFrontiers in Aging Neuroscience, 2020
Reduced pain tolerance may be one of the possible explanations for high prevalence of chronic pain among older people. We hypothesized that age-related alterations in pain tolerance are associated with functioning deterioration of the frontal cortex ...

Apathy as a Risky Neuropsychiatric Syndrome of Progression From Normal Aging to Mild Cognitive Impairment and Dementia: A Systematic Review and Meta-Analysis

open access: yesFrontiers in Psychiatry, 2021
Background: Apathy has been suggested as a potential predictor of mild cognitive impairment (MCI) progression to dementia. Whether it might predict the transition from normal cognitive function to cognitive impairment has been less studied.
