A medical suspense novel that although it is a little dated, still is very much valid in terms of diagnosing and symptoms related to brain diseases. The cases represented are fascinating to read about the diagnosis, and the description of the symptoms the patient experiences, especially since I am all too familiar with them. Some of the medical descriptions are a bit wordy for my taste, but the author did a great job in keeping the jargon to a minimum and easy to read and understand without having a medical dictionary near by. NOW, having said all that, the computer stuff was very humorous.. 40 years of computer technology has come a long way, and I imagine the computers they are describing making lots of 80's computer noises (beep beep boop) and lots of flashing lights, like when the death star is getting powered up.. considering the room sized computers they speak of which are "top of the line" don't even come close to your cell phone or computer you are reading this on now.. I guess a bit of imagination is required to get past that part... overall a good read for sure, not bad for a book I picked up for free from a lending library...
