High Stress May Damage Memory According to a report issued in May 1998, elderly people who have consistently high blood levels of cortisol don’t score as well on memory tests as their peers with lower levels of the stress hormone. What’s more, high levels of cortisol are also associated with shrinking of the hippocampus, a region of the brain that plays a key role in learning and memory. The findings suggest that even cortisol levels in the normal, "healthy" range can actually acceIerate 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-year period. Dr. Sonia Lupien and his colleagues measured 24-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 other 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. \ When the total volume of the hippocampus becomes smaller, other brain regions______.

Youth Emancipation in Spain The Spanish Government is so worried about the number of young adults still living with their parents that it has decided to help them leave the nest. Around 55 percent of people aged 18-34 in Spain still sleep in their parents’ home, says the latest report from the country’s state-run Institute of Youth. To coax(劝诱) young people from their homes, the Institute started a "Youth Emancipation(解放)" programme this month. The programme offers guidance in finding rooms and jobs. Economists blame young people’s family dependence on the precarious(不稳定的)labour market and increasing housing prices. Housing prices have risen 17 percent a year since 2000. Cultural reasons also contribute to the problem, say sociologists(社会学家). Family ties in south Europe—Italy, Portugal and Greece—are stronger than those in middle and north Europe, said Spanish sociologist Almudena Moreno Minguez in her report "The Late Emancipation of Spanish Youth: Key for Understanding". "In general, young people in Spain firmly believe in the family as the main body around which their private. life is organized," said Minguez. In Spain— especially in the countryside, it is not uncommon to find entire groups of aunts, uncles, cousins, nieces and nephews(外甥/侄子) all living on the same street. They regularly get together for Sunday dinner. Parents’ tolerance is another factor. Spanish parents accept late-night partying and are wary of setting bedtime rules. "A child can arrive home at whatever time he wants. If parents complain he’ll put up a fight and call the father a fascist," said Jos6 Antonio Gomez Yanez , a sociologist at Carlos III University in Madrid. Mothers’ willingness to do children’s household chores(家务) worsens the problem. Dionisio Masso, a 60-year-old in Madrid, has three children in their 20s. The eldest, 28, has a girlfriend and a job. But life with mum is good. "His mum does the wash and cooks for him; in the end, he lives well," Masso said. It can be inferred from paragraph 5 that family ties are stronger in Portugal than in
