One of the key concerns of older adults is experiencing memory loss, especially as it is one of the hallmark symptoms of Alzheimer's Disease. However, memory loss is qualitatively different in normal aging than it is in Alzheimer's Disease. Memory loss can be caused by many things. ...

Memory Decline Seen in Normal Aging The ability to encode new memories of events or facts and working memory show decline in both cross-sectional and longitudinal studies. These deficits may be related to impairments seen in the ability to refresh recently processed information. In addition, even when equated in memory for a particular item or fact, older adults tend to be worse at remembering the source of their information, a deficit that may be related to declines in the ability to bind information together in memory. In cognitive psychology, working memory is the collection of structures and processes used for temporarily storing and manipulating information. ...
Domains of Memory Mostly Spared in Normal Aging In contrast, implicit, or procedural memory typically shows no decline with age and semantic knowledge, such as vocabulary, actually improves somewhat with age. In addition, the enhancement seen in memory for emotional events is also maintained with age. Procedural memory, also known as implicit memory, is the long-term memory of skills and procedures, or how to knowledge. ...
Memory is the ability of the brain to store, retain, and subsequently recall information. ...
Qualitative Changes in Memory Processing with Age Most research on memory and aging has focused on how older adults perform less well at a particular memory task. However, recently researchers have also discovered that simply saying that older adults are doing the same thing, only less of it, is not always accurate. In some cases, older adults seem to be using different strategies than younger adults. For example, brain imaging studies have revealed that older adults are more likely to use both hemispheres when completing memory tasks than younger adults. In addition, older adults often show a positivity effect when remembering information, which seems to be a result of the increased focus on regulating emotion seen with age. The positivity effect refers to the tendency for people to attribute the positive behavior of other people whom they like to their disposition, while attributing negative behavior to their situation. ...
