My friend gave me a great little notebook for Christmas so that I could remember my days/ life!! It's called Me! A Personal Journal, from the Write It Down series. By www.JournalsUnlimited.com
Another good tool for the memory slippage is by DayTimers Inc. They've just created a calendar pak for Brain Injury recovery that looks so wonderful it made me drool!! I'm sure it would be terrific for people with memory and concentration decline. it has color coded tags and a helper pak too.
