Keep a detailed diary of your memory lapses throughout your day. Note the time they occur and what the situations are.
Target Specific Problems
Use your daily diary to determine what influences your memory problems. If they're more noticeable in the early afternoon, prepare yourself by not scheduling meetings or deadlines then.
Make a list of what you need to accomplish each day and use it as a guide. Take detailed notes about things you need to remember.
Put commonly misplaced objects (such as your keys) in the same place every time you put them down.
Be open with your friends and family about what you're experiencing. Let them know your mind is moving a little more slowly these days and explain how they can help.
