Without seeing all of the films I can not be certain what the radiologists are commenting on, but I believe they are all commenting on the same findings. These findings are most commonly described as non-specific (meaning that the changes do not suggest a particular problem) white mater abnormalities. Most individuals in their 50-60's will have some degree of this. Possible casues for these changes include migraines/headaches, high blood
pressurePressure ulcer, and diabetes to name a few. Without viewing the films I can not tell you if they suggest a particular disorder. Good luck.
