'Brain decline' begins at age 27

[Sachinism]

Mental powers start to dwindle at 27 after peaking at 22, marking the start of old age, US research suggests. Professor Timothy Salthouse of Virginia University found reasoning, speed of thought and spatial visualisation all decline in our late 20s. Therapies designed to stall or reverse the ageing process may need to start much earlier, he said. His seven-year study of 2,000 healthy people aged 18-60 is published in the journal Neurobiology of Aging. To test mental agility, the study participants had to solve puzzles, recall words and story details and spot patterns in letters and symbols. The same tests are already used by doctors to spot signs of dementia. In nine out of 12 tests the average age at which the top performance was achieved was 22. The first age at which there was any marked decline was at 27 in tests of brain speed, reasoning and visual puzzle-solving ability. Things like memory stayed intact until the age of 37, on average, while abilities based on accumulated knowledge, such as performance on tests of vocabulary or general information, increased until the age of 60. Professor Salthouse said his findings suggested "some aspects of age-related cognitive decline begin in healthy, educated adults when they are in their 20s and 30s." Rebecca Wood of the Alzheimer's Research Trust agreed, saying: "This research suggests that the natural decline of some of our mental abilities as we age starts much earlier than some of us might expect - in our 20s and 30s. "Understanding more about how healthy brains decline could help us understand what goes wrong in serious diseases like Alzheimer's. "Alzheimer's is not a natural part of getting old; it is a physical disease that kills brain cells, affecting tens of thousands of under 65s too. "Much more research is urgently needed if we are to offer hope to the 700,000 people in the UK who live with dementia, a currently incurable condition." http://news.bbc.co.uk/1/hi/health/7945569.stm ==== In 4 years I'll start old age :nervous:

[Desi Cartman]

I cant understand :dontknow: oh that because Im 30 btw it means @mits is at his prime :haha:

[cowboysfan]

oh no-i more to go:((

[coffee_rules]

I think that is the reason why people get married after 27, usually. Their mental powers start to dwindle!:cantstop:

[nikred]

oh cr@p less than two months left for my mental powers to start dwindling.:omg: i feel old:((

[Holysmoke]

I am at the peak of my powers

[Sachinism]

I am at the peak of my powers

Im supposed to be at my peak, doesn't feel like it If this is my peak, god help me lol

[punjabi_khota]

I am at the peak of my powers

Thats a pity because you don't seem too sharp right now. :finger: 2 years before I get old. :agree: P.S: What the **** is Virginia university ?

I agree, I really dont remember why I banned last 3 users..damn

Nonsense, Age is just an imaginary number. I have seen 70 year emeritus professors do really complex digital designs like it was single digit addition. Like most other things, the brain gets better the more you use it. If you don’t use it enough, it doesn’t matter how old you are, it will begin to rust.

I said I'm at the peak of my powers. Doesnt mean I'm sharp. :eyedance:

..funny, heard the same thing in the radio this morning

They can do those because they are accustomed to and are probably doing them for 50 years. If you read (auto)biographies of famous Math personalities, they all seem to agree with the fact that your ability to do original research goes down and it is very rare to do something really big after say age 45-50. Andrew Wiles may be an exception. The best book on topic: A Mathematician's Apology by Hardy.

The only difference here is that I doubt that if any of us here are going to do ‘original mathematical research’ or anything as intellectually challenging as that, by the time we’re 45. These ‘research findings’ can say whatever they want, but everyday in my life, I see people nearly twice, even thrice my age being sharp, with excellent memory and great attention to detail. I wont be surprised if this research was funded my a drug company which intends on selling memory enhancing tablets for old people or something. Don’t forget, no research on this planet happens just for research’s sake. Everything has a hidden commercial interest propelling it. Besides, most of these research findings are really dodgy. Many times in the past, such findings have been contradicted by subsequent investigations.

That's true. No Fields medal above age 30. I envy you kids.

40 sir, 40. :two_thumbs_up:

[h4te]

you guys are all old :hehe:
