Normal age-related changes in the brain can slow some cognitive processes, making it a bit harder to learn new things quickly or to ward off distractions.

1. Believe in yourself (People who believe that they are not in control of their memory function are less likely to work at maintaining or improving their memory skills and therefore are more likely to experience cognitive decline.)
2. Economize your brain use (If you don’t need to use mental energy remembering where you laid your keys or the time of your granddaughter’s birthday party, you’ll be better able to concentrate on learning and remembering new and important things. There are a number of strategies that help. )
3. Organize your thoughts
4. Use all your senses  (The more senses you use in learning something, the more of your brain will be involved in retaining the memory. So challenge all your senses as you venture into the unfamiliar.)
5. Expand your brain (Use multiple modalities  when learning: reading, saying things aloud, drawing pictures and creating things with your hands. it helps create more in depth memories.)
6. Repetition (Repeat, repeat … repeat: Repetition is potent - When you want to remember something you’ve just heard, read, or thought about, repeat it out loud or write it down. That way, you reinforce the memory or connection.)
7. Spacing (Repetition is most potent as a learning tool when it’s properly timed. It’s best not to repeat something many times in a short period, as if you were cramming for an exam.)
8. Mnemonics (Mnemonic devices can take the form of acronyms, sentences or stories.)
9. Keep learning (Experts think that advanced education may help keep memory strong by getting a person into the habit of being mentally active. Challenging your brain with mental exercise is believed to activate processes that help maintain individual brain cells and stimulate communication among them.)
