Annals of Neurology, 1985
AbstractPostmortem and computed tomographic studies demonstrate many anatomical, morphological, and neurochemical differences between brains of old and young human beings. The variability of the results is great, however, and brains of some old subjects have characteristics of brains of younger controls.

Pathophysiology of Ageing Brain
Gerontology, 1987Even in nonfamilial cases of dementia there is some evidence of a genetic factor. This may be linked to defective expression of neurofilament protein and also abnormal phosphorylation of cytoskeletal proteins. In this respect there may be a link with accumulation of tangles and amyloid which have some degree of homology.

Current Opinion in Neurology, 1994
This review considers some of the changes that occur during aging in the mammalian central nervous system. We focus particularly on neurotransmitter systems, calcium homeostasis, synaptic transmission, oxidative metabolism, amyloid deposition, and other neuropathological and anatomical features.

Mechanisms of Ageing and Development, 2002
The brains of individuals who are cognitively normal show age-related changes that include an overall reduction in the brain volume and weight and enlargement of the brain ventricles. These changes are partly the result of nerve cell loss but accurate estimates of neuronal loss are notoriously difficult to make.

Brain Microvasculature in Aging
Neurobiology of Aging, 1994Integrity of the cerebral microvasculature is an important issue in aging. Mooradian has made concerted efforts to examine the biochemical properties of cerebral microvessels in aging rats. There is not a clear consensus on the alterations identified but some of these could have repercussions on vascular permeability or global perfusion during aging.

Journal of Cardiothoracic and Vascular Anesthesia, 2019
Herein, the authors review the neuroanatomical and the neurophysiological aspects of the normal aging evolution based on the recent literature and briefly describe the difference between physiological and pathological brain aging, with consideration of the currently recommended anesthesia management of older patients. The population of elderly patients

Medical Clinics of North America, 2011
Optimal cognitive and emotional function is vital to independence, productivity, and quality of life. Cognitive impairment without dementia may be seen in 16% to 33% of adults older than 65 years, and is associated with significant emotional distress. Cognitive and emotional well-being are inextricably linked.
