As a person gets older, changes occur in all parts of the body, including the brain. Certain parts of the brain shrink, especially those important to learning and other complex mental activities. In certain brain regions, communication between neurons (nerve cells) may not be as effective.
Memory decline is one of the first things that concern people about growing older — it can start after the age of 20, so being more forgetful when you are 60 or 70 is often normal.
Age is often associated with a decline in cognitive abilities that are important for maintaining functional independence, such as learning new skills. Many forms of motor learning appear to be relatively well preserved with age, while learning tasks that involve associative binding tend to be negatively affected.
At what specific age does it become more difficult to learn new things? At the age of 26 human mind has highest peak value for learning. After 26 it remain constant for some time and then starts decreasing slowly till the age of 40.
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.
Although you may face some extra difficulties at 30, 50 – or 90 – your brain still has an astonishing ability to learn and master many new skills, whatever your age.
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.
This declining ability is often called fluid intelligence. By contrast, the ability to accumulate knowledge, whether in school or by other cultural experiences, increases with age until a person is in their 60s (when level of education is controlled), and doesn't start declining until age 75.
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.
The hippocampus, a region of the brain involved in the formation and retrieval of memories, often deteriorates with age. Hormones and proteins that protect and repair brain cells and stimulate neural growth also decline with age.
Major memory changes don't always signal Alzheimer's disease. They can be caused by strokes, head injuries, lack of vitamins in your diet, or sleep trouble. They might even be a side effect of one of the drugs you're taking. When in doubt, see a doctor to sort it out.
We found that the 4- to 12-year-old age groups showed the strongest learning effect measured by the raw RT difference scores.
Depression, anxiety and stress – “These are common causes of forgetfulness,” Lyndsay said. “Stress and mood disturbances can act as a distraction and make it difficult to focus, which can lead to memory problems.”
It could be because they are tired of learning and "just want to relax" or perhaps they feel that they've "graduated" and learned all they needed to know.

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.
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.
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.
This is key as we tend to stop learning as we get older. Research suggests that by age 25 our brains tend to get "lazy." It's not that our gray cells can no longer learn new things, but rather we rely on a set number of neuro pathways to do our thinking. In other words, we get stuck in a brain rut.
A large body of research about aging tells us that as we cross the threshold into middle age, neural connections that receive, process and transmit information can weaken from age and disuse. It may take us longer to learn new information. We often can't think as sharply or as quickly. Our reaction times may be slower.
It is never too late to go to college or benefit from the advantages of a postsecondary degree.
The Mini-Cog test.
A third test, known as the Mini-Cog, takes 2 to 4 minutes to administer and involves asking patients to recall three words after drawing a picture of a clock. If a patient shows no difficulties recalling the words, it is inferred that he or she does not have dementia.
Introduction: The five-word test (5WT) is a serial verbal memory test with semantic cuing. It is proposed to rapidly evaluate memory of aging people and has previously shown its sensitivity and its specificity in identifying patients with AD.
