People with improved cognitive function perform better on memory tasks, remain mentally alert and excel at their workplace. On the other hand, reduced cognitive function leads to premature ageing and reduces life expectancy.
There are several ways to improve better cognition and lessen the chance of diminished cognitive ability.

Exercise improves cognitive function
Regular exercise increases learning capacity, the ability to handle stressful situations, take wise decisions and recollect facts and memories.

Reading and watching TV
There is a difference between watching a daily soap on TV and watching an educational program. Similarly, a tabloid magazine takes less brain power to flip through than a serious book. After watching TV or reading a book, people can recall what they have learned. This exercise improves memory retention capacity.

Taking up a new hobby
One can increase cognitive function by taking up a new active pursuit that involves some sort of learning, for example, learning a foreign language, taking up gardening, learning to play a musical instrument or attending seminars and conferences. All these activities can keep people mentally alert and active.

Solve different types of puzzles
In order to build new connections in the brain, one should try different types of puzzles. Crosswords, cryptograms, acrostics and syllacrostics are some of the popular word oriented brain teasers which are good for the smart functioning of the brain. Switching from a puzzle to another stimulates the activity of the brain.

Engage in board and card games
Chess, scrabble and wheel of fortune are some of the popular games which require different types of strategies each time. Card games preserve cognitive functioning because the player perfects the most effective strategies according to opponents playing style. One can easily play these games on the computer.

Visit to historical sites, museums and zoos
A person can improve his cognition ability by visiting historical sites and zoos. By reading the signage next to the exhibits and repeating the key information to themselves several times after the visit, one can recall the information even after several years.

Reduce stress and depression
Stressed individuals are more prone to suffer from cognitive issues than people who are tension free. Besides medications, people should try to manage their stress and depression through regular exercise, meditation, spiritual growth, counseling, good night sleep and other means.

Cognitive thought and behaviour can also be improved with the prescribed dose of a wakefulness-promoting agent called Modafinil.
