Neuroscientists find that different parts of the brain work best at different ages. Scientists have long known that our ability to think quickly and recall information, also known as fluid intelligence, peaks around age 20 and then begins a slow decline.
They conclude that humans reach their cognitive peak around the age of 35 and begin to decline after the age of 45. And our cognitive abilities today exceed those of our ancestors. “Performance reveals a hump-shaped pattern over the life cycle,” report the authors in Proceedings of the National Academy of Sciences.
In addition to slowing down physically, most people lose points on intelligence tests as they enter their golden years. Now, new research suggests the loss of certain types of cognitive skills with age may stem from problems with basic sensory tasks, such as making quick judgments based on visual information.
The brain's capacity for memory, reasoning and comprehension skills (cognitive function) can start to deteriorate from age 45, finds research published on bmj.com today.

Strength peaks at age 25.
Your muscles are at their strongest when you're 25, although for the next 10 or 15 years they stay almost as hefty - and this is one of the traits that can be most easily improved, thanks to resistance exercise.
Smaller improvements are still noticeable from age 20 until what the researchers described as a “peak” begins at age 35. The peak lasts until roughly age 45, at which point chess skill – and, the study theorizes, overall mental performance – begins a marked decline.
Our ability to remember new information peaks in our 20s, and then starts to decline noticeably from our 50s or 60s. Because the hippocampus is one brain region that continues producing new neurons into adulthood, it plays an important role in memory and learning.
IQ peaks at around 20-years-old and later effort will not improve it much beyond this point, research finds. The complexity of people's jobs, higher education, socialising and reading all probably have little effect on peak cognitive ability.
Two-year-olds have twice as many synapses as adults. Because these connections between brain cells are where learning occurs, twice as many synapses enable the brain to learn faster than at any other time of life.
In the UNH study, researchers found a pronounced "reminiscence bump" between ages 17 and 24, when many people defined chapters of their life story beginning and ending. A reminiscence bump is a period of time between the ages of 15 and 30 when many memories, positive and negative, expected and unexpected, are recalled.
Wisdom peaks after age 60.
According to a 2010 study, the people who performed best at analyzing a given conflict, seeing different points of view, gauging uncertainties, and envisioning solutions, were people who were at least 60 years old.
Aging may also bring positive cognitive changes. For example, many studies have shown that older adults have more extensive vocabularies and greater knowledge of the depth of meaning of words than younger adults. Older adults may also have learned from a lifetime of accumulated knowledge and experiences.
Is there a moment in a person's life when they feel most fulfilled, happiest, or in their prime? Again, the most obvious answer to some might be somewhere around 25. But survey data from YouGov suggest that many consider the prime age to actually be 37.
- In the study, men's desirability peaks at age 50. But women's desirability starts high at age 18 and falls throughout their lifespan.
The 20s...it's the phase where so many things change in our lives and it all happens so fast. There's angst, discovery, unpredictability and a sense of self-realization. It's the time we truly leave childhood behind and enter a whole new world of responsibility.
Anecdotally, smarter people do seem to live longer. Isaac Newton died in 1727 aged 84, the philosopher-mathematician Bertrand Russell lived to 97, while Nobel Prize-winning neurobiologist Rita Levi-Montalcini died in 2012 aged 103.
While age does not factor explicitly in the Berlin Model, Baltes and colleagues' research suggests that wisdom rises steadily from age 13 to 25 and then remains relatively stable through to age 75, after which a decline is common, correlated with the physical decline.
Most older people believe in the phrase “older and wiser”. Each of us can point to situations where we behaved better as older people than we did when we were young. However, recently, researchers have examined the phrase and found that older people aren't necessarily wiser.
A YouGov poll of more than 13,000 Americans finds that 24% do believe that your 20s represent the best years of their lives, but a roughly equal amount (23%) believe that the 30s are actually the best years.
And structural plasticity is when your brain changes its structure due to learning. It's strongly believed that once we hit 25, the brain's plasticity solidifies. This makes it harder to create neural pathways. In turn, this can mean it's tougher to learn new skills.
Neuroplasticity is the brain's ability to reorganize itself by forming new neural pathways throughout life and in response to experiences. While the brain usually does this itself in response to injury or disease, when humans focus their attention enough, they can slowly rewire these pathways themselves.
Scientists explained our brains don't reach adulthood until our 30s at a new meeting on brain development. Our brains are constantly developing over a span of three decades. This means that certain behaviors, like excessive alcohol consumption, can be particularly damaging when we're young.
