Practicing a new and challenging activity is a good bet for building and maintaining cognitive skills. Your brain has the ability to learn and grow as you age — a process called brain plasticity — but for it to do so, you have to train it on a regular basis.
The smarter the person, the faster information zips around the brain, a UCLA study finds. And this ability to think quickly apparently is inherited. The study, published in the Journal of Neuroscience, looked at the brains and intelligence of 92 people. All the participants took standard IQ tests.
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.

For example, raw speed in processing information appears to peak around age 18 or 19, then immediately starts to decline. Meanwhile, short-term memory continues to improve until around age 25, when it levels off and then begins to drop around age 35.
Diabetes, smoking, high blood pressure, and other vascular risk factors can starve the brain of oxygen and glucose, resulting in slower thinking. What is this? Slow thinking can be a lingering side effect of a traumatic brain injury or stroke, or a sign of multiple sclerosis, dementia, or Alzheimer's.
This can be caused by overworking, lack of sleep, stress, and spending too much time on the computer. On a cellular level, brain fog is believed to be caused by high levels inflammation and changes to hormones that determine your mood, energy and focus.
Green, leafy vegetables. Leafy greens such as kale, spinach, collards, and broccoli are rich in brain-healthy nutrients like vitamin K, lutein, folate, and beta carotene. ...
By the age of 6, the size of the brain increases to about 90% of its volume in adulthood. Then, in our 30s and 40s, the brain starts to shrink, with the shrinkage rate increasing even more by age 60.
Why can't I concentrate and focus? Loss of focus can happen for many reasons. They include mental and physical health problems, stress, the use of some medications, and a lack of sleep or and inadequate diet.
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.
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.
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.
Take time for walking breaks, snack breaks, and brain rest. This can help you recharge and avoid cognitive overload. Make study periods longer and more focused. The longer you study, the more likely you'll end up struggling to maintain your concentration.
Try to avoid ultra-processed products when you are studying as these are often energy dense, high in sugar and fat. Optimise healthy food intake through eating a range of foods from the five food groups: Vegetables and legumes/beans. Fruit.
Green tea is an excellent beverage to support your brain. Its caffeine content boosts alertness, its antioxidants protect the brain, and L-theanine helps you relax.
