- 研究人员说，老年人有时很难记住事情的原因之一是，有很多记忆和信息可以筛选。
- 专家说，这个大脑“混乱”并不是全部不好。这些额外的数据可以帮助制定决策。
- They add that exercising regularly, maintaining a healthy diet, and staying socially active can help with memory as you age.
Most people past a certain age know the feeling.
您已经与Susan一起从事许多项目。您的桌子彼此对面。您甚至不止一次为她拿起咖啡，并可以记住她的订单。
But her last name?
You search your brain and just – in that moment — cannot find it.
You scold yourself and wonder: Am I losing my memory?
一个research review2月11日发布的理论认为，这种困难以及我们年龄的其他记忆挑战可能是由于信息过多而不是缺乏信息的结果。
In other words, as we age, we may have an overload of data and memories to shuffle through to find that one piece we desire.
Tarek Amer, the lead researcher on the study and a postdoctoral fellow in cognitive neuroscience at Columbia University in New York and Harvard University in Massachusetts, says the findings challenge some past assumptions about aging, the brain, and memory.
“这违背了较老的大脑不会存储太多的想法。这是贫穷的。”他告诉Healthline。雷竞技app官网
一个mer and his team looked at research that compared memory storage between younger adults and older adults from 60 to 85 years of age.
这项研究检查了创造性的任务，以了解人们的回忆和忘记。
它发现老年人坚持信息，缺乏忽略大部分信息的能力。
So, Amer said, given the notion of someone trying to recall Susan’s last name, he said, “You have five or more people named Susan (stored in your memory),” so you have to go through all that to find the correct one.
He calls that process “interference.”
它也可以被认为是一个很大的步入式壁橱，您多年来堆着毛衣和其他衣服。您知道您将自己喜欢的蓝色毛衣放在其中，但是发现它需要时间。
Thomas Laudate, PhD, a clinical neuropsychologist at Tufts Medical Center in Massachusetts, described the concept of older adults’ brains having added information to cull through like a photo with “too many pixels.”
He told Healthline that this theory – he does not see it as proof yet – possibly opens the door to more information on how the brain works as we age and what we can do about that.
“It helps give us more information about the underpinning of memories,” Laudate said. “It would be interesting (to explore) if there are ways these theories can be applied to enhance memory.”
Dr. Glen R. Finney美国神经病学学会的研究员,said the findings are not surprising.
“This is something that I have thought of for quite a while,” he told Healthline.
Several years ago, Finney said, a study showed college students pictures of famous people and timed how long it took them to name the famous person. The students were asked how many people they knew with various first names (including the first names of the famous people).
“The more people that they knew with the same first name as the famous person, the slower they were to retrieve that name,” he said.
Finney指出：“这意味着您知道的越多，找到所需的特定信息所需的时间就越长，这是有道理的。”“我喜欢将其视为多年来我们居住的几年和数十年来积累智慧的代价。”
Can we clean up our brains to work better around this? And should we?
阿米尔说，随着研究人员的深入研究，他们可能还会发现，多余的信息也可能是一件好事。
“This is where some emerging evidence shows that this might be helpful,” he said. “Sometimes information not retrieved in one (effort) could be useful in another.”
芬尼（Finney）一方面看到了杂物。
他说：“并非所有的混乱都不好。”“您拥有的信息越多，创造力的工厂越多，有时候杂物会导致新颖的思想和思想。”
阿米尔说：“我们想关注这一想法，即这并不总是很糟糕。”
他说，年龄较大的参与者倾向于创造性地表现更好，因为他们“在记忆中编码”要使用。
他说，需要做更多的工作来将其链接到可能有助于在老年中记忆的动作。
If you’re still trying to remember Susan’s last name, you’re not alone.
一个nd while experts say it’s too soon to draw actionable things from this latest study, there are ways to work on keeping your brain working well.
Laudate suggests:
- Regular aerobic exercise.It does not, he said, have to be hard core; any kind of regular aerobic movement helps. “If the benefits of exercise could bet put in a pill, it would sell millions,” he said.
- 吃营养丰富，均衡的饮食。
- Stay intellectually and socially active.“Those can often be done together,” he said. Book groups, film discussions, or whatever interests you.
You can also work on your memory itself, Finney said.
他说：“我们需要更好地理解的一个有趣的因素是忘记或学习以前获取的信息的价值，以便更有用的实践或信息可以升至最前沿。”
他补充说：“到目前为止，我们知道这样做的最好方法是专注于使用和学习更好的活动和信息，而不是使用或练习较少有用的混乱。”
Finney is also a believer in meditation.
他说：“我认为仍然需要进一步的研究来真正讲述最佳实践，以使大脑的混乱降低，但是一种可能的途径可能是练习冥想，这可以帮助安静下来，并有助于专注于故意关注。”
What won’t work?
劳达特说：“您在电视上听说这些补品。”“据我们所知，它们并不特别有用。而且它们非常昂贵。”
他说，如果您对补品有强烈的感觉，请参阅您的初级保健医生，询问他们是否有任何维生素缺乏症，并让他们指导您添加到日常工作中。
