High Stress May Damage Memory
According to a report issued in May 1998，elderly people who have consistently high b1ood levels of cortisol don’t score as well on memory tests as their peels with lower levels of the stress hormone．What’s more． high 1evels of cortisol are also associated with shrinking 0f the hippocampus，a region of the brain that plays a key role in learning and memory．The 6ndings suggest that even cortisol levels in the normal，“healthy” range can actually accelerate brain aging．
The study results “now provide substantial evidence that long—term exposure to adrenal stress hormones may promote hippocampal aging in normal elderly humans，”write Nada Porter and Philip Landfield of the University of Kentucky in Lexington in their editorial．Cortisol is a hormone released in response to stress by the adrenal glands，which sit on top of the kidneys．
Over a 5 to 6一year period，Dr． Sonia Lupien and his colleagues measured 24一hour cortisol levels in 51 healthy volunteers，most of Whom were in their 70s．
Despite wide variation in cortisol levels．the participants could be divided into three Subgroups：those whose cortisol progressively increased over time and was currently high（increasing／high）：those whose cortisol progressively increased over time and was currently moderate（increasing／moderate）；and subjects whose cortisol decreased，but Was currently moderate（decreasing／moderate）．
The researchers tested the volunteers’ memory on six people in the increasing／high category and five people in the decreasing／moderate group．The groups did not differ on tests of immediate memory，but the increasing／high cortisol group had other memory problems compared with those in the decreasing／moderate group．
The researchers also found that the total volume of the hippocampus in those in the increasing／high group was 14％ lower than those in the decreasing／moderate group，although there were no differences in 0ther brain regions．
The results suggest that brain aging Can be accelerated by levels of adrenal hormones that are not generally regarded as pathological and that variation within this normal range is related to variation in the rate of brain aging．”write Porter and Landfield．“This further suggests that chronic stress may accelerate the worsening of hippocampus．”
第 26 题 The part of the brain important for a person’s learning and memory is．
A．the cortisol．
B．the adrenal glands．
C．the stress hormones
D．the hippocampus．

experimenting on mice. They are studying the relationship between diet and health. At this time, over one hundred experiments are being done in this laboratory.
In one of these experiments, the scientists are studying the relationship between the amount of food the mice eat and their health. The mice are in three groups. All three groups are receiving the same healthy diet. But the amount of food that each group is receiving is different. The first group is eating one cup of food each day, the second group is eating two cups, and the third group of mice is eating three cups.
After three years, the healthiest group is the one that is only eating one cup of food each day. The mice in this group are thinner than normal mice. But they are more active. Most of the day, they are running, playing with one another, and using the equipment in their cages. Also, they are living longer. Mice usually live for two years. Most of the mice in this group are still alive after three years.
The second group of mice is normal weight. They are healthy, too. They are active, but not as active as the thinner mice. But they are only living about two years, not the three years or more of the thinner mice.
The last group of mice is receiving more food than the other two groups. Most of the day, these mice are eating or sleeping. They are not very active. These mice are living longer than the scientists thought - about a year and a half. But they aren't as healthy. They're sick more often than the other two groups.

Losing your ability to think and remember is prettyscary. We know the risk of dementia (痴呆症) increases with age. But if you have memory slips, you probably needn't worry. There are pretty clear differences between signs of dementia andage-related memory loss. After age 50, it's quite common to have trouble remembering the names of people, places andthings quickly, says Dr. Kirk Daffner of Brigham and Women's Hospital in Boston. The brain ages just like the rest of the body. Certain parts shrink, especially areas in the brainthat are important to learning, memory and planning. Changes in brain cells can affectcommunication between different regions of the brain. And blood flow can be reduced asblood vessels narrow. Forgetting the name of an actor in a favorite movie, for example, is nothing to worry about. Butif you forget the plot of the movie or don't remember even seeing it, that's far moreconcerning, Daffner says. When you forget entire experiences, he says, that's "a red flag that something more seriousmay be involved." Forgetting how to operate a familiar object like a microwave oven, orforgetting how to drive to the house of a friend you've visited many times before can also besigns of something going wrong. But even then, Daffner says, people shouldn't panic. There are many things that can causeconfusion and memory loss, including health problems like temporary stoppage of breathingduring sleep, high blood pressure, or depression, as well as medications (药物) likeantidepressants. You don't have to figure this out on your own. Daffner suggests going to your doctor to checkon medications, health problems and other issues that could be affecting memory. And the bestdefense against memory loss is to try to prevent it by building up your brain's cognitive (认知的) reserve, Daffner says. "Read books, go to movies, take on new hobbies or activities that force one to think in novelways," he says. In other words, keep your brain busy and working. And also get physicallyactive, because exercise is a known brain booster.Why does the author say that one needn't be concerned about memory slips？ 1..Why does the author say that one needn't be concerned about memory slips？()
