How to boost your brain power at any age ?

By the time you've reached adulthood, your brain has developed millions of neural pathways that help you process and recall information quickly, solve familiar problems, and execute habitual tasks with a minimum of mental effort. But if you always stick to these well-worn paths, you aren't giving your brain the stimulation it needs to keep growing and developing. You have to shake things up from time to time!

Memory, like muscular strength, requires you to “use it or lose it.” The more you work out your brain, the better you'll be able to process and remember information. But not all activities are equal. The best brain exercises break your routine and challenge you to use and develop new brain pathways.

Four key elements of a good brain-boosting activity

It teaches you something new. No matter how intellectually demanding the activity, if it's something you're already good at, it's not a good brain exercise. The activity needs to be something that's unfamiliar and out of your comfort zone. To strengthen the brain, you need to keep learning and developing new skills.
It's challenging. The best brain-boosting activities demand your full and close attention. It's not enough that you found the activity challenging at one point. It must still be something that requires mental effort. For example, learning to play a challenging new piece of music counts; playing a difficult piece you've already memorized does not.
It's a skill you can build on. Look for activities that allow you to start at an easy level and work your way up as your skills improve —always pushing the envelope so you continue to stretch your capabilities. When a previously difficult level starts to feel comfortable, that means it's time to tackle the next level of performance.
It's rewarding. Rewards support the brain's learning process. The more interested and engaged you are in the activity, the more likely you'll continue doing it and the greater the benefits you'll experience. So, choose activities that, while challenging, are still enjoyable and satisfying.

Think of something new you've always wanted to try, like learning how to play the guitar, make pottery, juggle, play chess, speak French, dance the tango, or master your golf swing. Any of these activities can help you improve your memory, so long as they keep you challenged and engaged.

What about brain-training programs?

There are countless brain-training apps and online programs that promise to boost memory, problem-solving skills, attention, and even IQ with daily practice. But do they really work?

Increasingly, the evidence suggests no. While these brain-training programs may lead to short-term improvements in whatever task or specific game you've been practicing, they don't appear to strengthen or improve overall intelligence, memory, or other cognitive abilities.

Brain-boosting exercise tips

Aerobic exercise is particularly good for the brain, so choose activities that keep your blood pumping. In general, anything that is good for your heart is great for your brain.
Does it take you a long time to clear out the sleep fog when you wake up? If so, you may find that exercising in the morning before you start your day makes a big difference. In addition to clearing away the cobwebs, it also primes you for learning throughout the day.
Physical activities that require hand-eye coordination or complex motor skills are particularly beneficial for brain building.
Exercise breaks can help you get past mental fatigue and afternoon slumps. Even a short walk or a few jumping jacks can be enough to reboot your brain.

Stress is one of the brain's worst enemies. Over time, chronic stress destroys brain cells and damages the hippocampus, the region of the brain involved in the formation of new memories and the retrieval of old ones. Studies have also linked stress to memory loss.

Tips for managing stress

Set realistic expectations (and be willing to say no!)
Take breaks throughout the day
Express your feelings instead of bottling them up
Set a healthy balance between work and leisure time
Focus on one task at a time, rather than trying to multi-task

The following nutritional tips will help boost your brainpower and reduce your risk of dementia:

Get your omega-3s. Research shows that omega-3 fatty acids are particularly beneficial for brain health. Fish is a particularly rich source of omega-3, especially cold water “fatty fish” such as salmon, tuna, halibut, trout, mackerel, sardines, and herring.

If you're not a fan of seafood, consider non-fish sources of omega-3s such as seaweed, walnuts, ground flaxseed, flaxseed oil, winter squash, kidney and pinto beans, spinach, broccoli, pumpkin seeds, and soybeans.

Limit calories and saturated fat. Research shows that diets high in saturated fat (from sources such as red meat, whole milk, butter, cheese, cream, and ice cream) increase your risk of dementia and impair concentration and memory.

Eat more fruit and vegetables. Produce is packed with antioxidants, substances that protect your brain cells from damage. Colorful fruits and vegetables are particularly good antioxidant “superfood” sources.

Drink green tea. Green tea contains polyphenols, powerful antioxidants that protect against free radicals that can damage brain cells. Among many other benefits, regular consumption of green tea may enhance memory and mental alertness and slow brain aging.

Drink wine (or grape juice) in moderation. Keeping your alcohol consumption in check is key, since alcohol kills brain cells. But in moderation (around 1 glass a day for women; 2 for men), alcohol may actually improve memory and cognition. Red wine appears to be the best option, as it is rich in resveratrol, a flavonoid that boosts blood flow in the brain and reduces the risk of Alzheimer's disease. Other resveratrol-packed options include grape juice, cranberry juice, fresh grapes and berries, and peanuts.
