Didi’s neurological disorder is clearly quite different from
what you have encountered in previous chapters . His symp-
toms are intermittent rather than relentlessly progressive;
he appears to be completely normal when his symptoms
are not present . Nevertheless, it is important that you begin
the problem-solving process by reviewing the clinical data
provided and working through the history, examination,
localization and etiology worksheets in the accompany-
ing DVD . Once you have completed this process, you are
ready to proceed with the remainder of the chapter .
