Early on after my injury, like most people I got little help or support from the medical professionals. My family and I scoured the Internet and found many sources of information (especially this site) to describe the symptoms potential courses of action etc.
One of the sites ( can't remember which one

) had a list of common traits that head injury suffers indicate that are a problem. e.g. simple maths, repeating oneself etc. The idea being that you or your family use this list to give each item a score and then revisit it periodically.
I do mine every couple of months and have noticed - albeit subjective improvements in a number of areas. I don't take it terribly seriously but it does provide an indicator on progress and it does make you reflect on your own behavior and attitudes.
The version I use has around 120 measures and rather than post the entire list here is my summary and progress.
