question: A brain MRI finding is in part: The ventricles, cisterns, and other CSF containing spaces are diffusely prominent secondary to parenchymal volume loss. This is stable. There are confluent periventricular and patchy subcortical foci of increased signal on T2/FLAIR sequences consistent with gliosis secondary to chronic small vessel ischemic disease. These are stable. 1. What does this mean? 2. I am 85 years old, and about three months ago experienced an acute brain allergic reaction to a medication I was given. At that time, for about three weeks, I was confused and felt demented. Since then, I have largely recovered but feel some mild persisting reduction in intellectual functioning. My wife and I are considering moving from our present large single-family home to a senior-living community. Should we, considering the MRI findings, give preference to facilities equipped to deal with mental decline? If so, how much?
