Brain begins to decline at age 27

The human brain is the center of the human nervous system and is a highly complex organ. Enclosed in the cranium, it has the same general structure as the brains of other mammals, but is over three times as large as the brain of a typical mammal with an equivalent body size.
Mental powers start to dwindle at 27 after peaking at 22, marking the start of old age, US research suggests.
Professor Timothy Salthouse of the University of Virginia found reasoning, spatial visualisation and speed of thought 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.”
Brain Food Recommended:
Increase your mental agility and improve your memory by choosing the right foods.
Add vitality with vitamins
Folic acid and vitamin B12 help prevent homocysteine from building up in the body – levels of which have been found to be higher in people who have Alzheimer’s.
Fortified cereals are a great source of B12 and also contain complex carbohydrates which release energy over a long period and will keep you more mentally alert throughout the day.
We recently reported on the comprehensive health benefits from the highly unusual South American native berry called Acai…a berry that possesses not only all of the antioxidant, vitamin and brain benefits of other purple berries such as blueberries and blackberries but also (oddly, for a berry) contains Essential Fatty Acids like Omega-3’s like salmon, and and is even high in protein.
Pick up pumpkin seeds
Just a handful a day is all you need to get your recommended daily amount of zinc, vital for enhancing memory and thinking skills.
Ah, COFFEE. So popular, so ubiquitous, yet still so surprisingly misunderstood when it comes to “healthy or not”. How can this be?
You’d think that virtually everyone would be an expert on coffee these days, given the explosion of coffee chains like Starbucks over the last decade. Perhaps it’s because the situation is much like chocolate: the coffee bean, much like the cacao bean, is incredibly rich with antioxidants, amino acids, vitamins and minerals. Fresh-ground gently roasted coffee bean powder (again, like with cacao) has numerous brain and body health benefits…yes, including the caffeine content which has recently been shown to be GOOD for the brain, not bad, and particularly in the area of antioxidants. Regular coffee consumption has been shown to actually reduce the risk of mental decline and diseases such as Dementia and Alzheimer’s, and has also recently been found to be (shockingly) the “#1 source of antioxidants in the average American diet”…showing at once how health food-deprived the average diet continues to be while illustrating the surprising health benefits of something as common as coffee.
So where’s the controversy and confusion? The problem comes in when coffee is combined with other unhealthy things, as is so commonly done: triple-carmel-double-whip-chocolate-creme-mocha-blast-freeze drinks, weak over-extracted brewed cheap poor quality coffee, coffee loaded up with artificial cream and sweeteners, you know the drill. Compare such carb, chemical and fat-laden concoctions with, say, a high-quality organic coffee freshly ground into an Espresso-grade powder and served as a couple shots of fresh espresso, straight? No comparison. This should be obvious, but surprisingly, many or even most people still don’t get it.
Equally odd is that for many people, coffee is still viewed as a ‘vice’, something bad for you, something ‘naughty’ that should be avoided…as if it were akin to smoking cigarettes or pounding shots of tequila. The origin of this bizarre thinking comes partially from the effects of the caffeine (and other elements) which contribute to the stimulating effects of drinking coffee, and yes, for some people, coffee is contraindicated due to sensitivity to caffeine or gastrointestinal effects that coffee can sometimes produce.
But generally speaking, the coffee bean is a safe, true superfood. And when properly consumed in ideal forms (such as pure Espresso), it’s one uniquely enjoyable beverage that also packs a host of brain and health-friendly properties to boot!
Based on the knowledge that the food we eat directly affects the performance of our brain.
