For people nearing or over age 65, such common memory lapses can be frightening. The good news is that AD is not a normal part of aging. However, it is important to both understand that our brains change over time and to be able to distinguish normal changes from those that require medical and psychological attention. Although new neurons develop throughout our lifespans our brains reach their maximum size during our early twenties, and from that point, very slowly decline in volume. Blood flow to our brains also decreases over time. However, the good news is that numerous studies have shown that the brain remains capable of regrowth and of learning and retaining new facts and skills throughout life, especially for people who get regular exercise and frequent intellectual stimulation.
Memory and aging
Memory and aging - Wikipedia
Age-related memory loss , sometimes described as "normal aging ", is qualitatively different from memory loss associated with dementias such as Alzheimer's disease , and is believed to have a different brain mechanism. Mild cognitive impairment MCI is a condition in which people face memory problems more often than that of the average person their age. These symptoms, however, do not prevent them from carrying out normal activities and are not as severe as the symptoms for Alzheimer's disease AD. Symptoms often include misplacing items, forgetting events or appointments, and having trouble finding words. According to recent research, MCI is seen as the transitional state between cognitive changes of normal aging and Alzheimer's disease. Much like patients with Alzheimer's disease, those suffering from mild cognitive impairment have difficulty accurately defining words and using them appropriately in sentences when asked.
Excessive daily TV at older age tied to poorer memory
The aging process often results in a loss of memory, deteriorated intellectual function, decreased mobility, and higher rates of disease. Late adulthood is the stage of life from the 60s onward; it constitutes the last stage of physical change. Average life expectancy in the United States is around 80 years; however, this varies greatly based on factors such as socioeconomic status, region, and access to medical care.
