Older people are more likely to fear losing their mental abilities than their physical abilities. It is now becoming clear that cognitive health and dementia prevention must be lifelong pursuits.

Cognition is a combination of processes, including paying attention, learning and reacting to objects in the environment, and using language and memory. If cognition becomes impaired, an individual may have difficulty performing everyday tasks. Cognitive training is an important tool to keep cognition abilities as sharp as possible or improve already difficult situations. Training basic cognitive abilities is expected to also have a positive impact on how people exercise everyday abilities, such as managing one’s finances or medicines.

Cognitive training is based on the idea that the brain can change for the better. 

We know the brain suggests that it resembles muscles: In the same way that physical training improves physical abilities, cognitive training (or brain training) improves cognitive (or mental) abilities. 

Cognitive training uses guided practice on a set of tasks related to memory, attention, or other brain functions. This training can take many shapes. For instance, it can be conducted on the computer or delivered in person, either individually or in small groups. But it typically involves using repetitive exercises designed to improve single (e.g., memory) or multiple (e.g., memory and reasoning) cognitive abilities.  

Cognitive skills plays an important part in processing information. If any of cognitive skills is weak; grasping, retaining, or using information is impaired.
