In this article, we examine prominent theories of brain aging at the cellular level of analysis including the cholinergic hypothesis, oxidative stress, the calcium hypothesis, and genetic models of aging. Then, we discuss some of the age-associated changes in the vascular system and neuron numbers...

Lateral ventricle: Longitudinal values and age (aging of the brain) Increasing life expectancy with an accompanying rise in the incidence of diseases of the elderly has stimulated interest in the biology of aging. The total brain volume is usually stable, but later on diminishes over the last de...
The blood–brain barrier (BBB) protects the central nervous system (CNS) from unregulated exposure to the blood and its contents. The BBB also controls the blood-to-brain and brain-to-blood permeation of many substances, resulting in nourishment of the C
The article discusses episodic memory, which grows worse during normal aging of adult people. It says that episodic memory enables a person to execute daily intellectual and social activities as well as recalling series of events that happened. It states that one of the major worries of adult pe...
