It is also possible that the years of education a person has had and the amount of attention they received as a child might be a variable closely related to the links of aging and memory. [citation needed] There is a positive correlation between early life education and memory gains in older age. This effect is especially significant in women. [16]
Increased hyperpolarization, possibly due to dysfunctional calcium regulation, decreases neuron firing rate and plasticity. This effect is particularly pronounced in the hippocampus of aged animals and may be an important contributor to age-associated memory deficits. The hyperpolarization of a neuron can be divided into three stages: fast ...
Memory supports and enables social interactions in a variety of ways. In order to engage in successful social interaction , people must be able to remember how they should interact with one another, whom they have interacted with previously, and what occurred during those interactions.

Transitions such as reaching puberty, age of majority, or retirement are often socially significant. The concepts of successful aging and healthy aging refer to both social and physical aspects of the aging process. [3] [4]
The development of memory is a lifelong process that continues through adulthood. Development etymologically refers to a progressive unfolding.

The brain is usually capable of learning new skills in the aforementioned areas, typically in early childhood, and of developing personal thoughts and beliefs about the world. Old age and disease may affect cognitive functioning, causing memory loss and trouble thinking of the right words while speaking or writing ("drawing a blank").
[11] [a] Dementia ultimately has a significant effect on the individual, their caregivers, and their social relationships in general. [2] A diagnosis of dementia requires the observation of a change from a person's usual mental functioning and a greater cognitive decline than might be caused by the normal aging process.
