I had several MRI's because my father died of a disease called hydrocephalus. So, I asked to be monitored for this same disease. So far there has been no abnormalities reported except a small lesion due to a TIA I had a few years ago. As for the trials with low dose naltrexone, I am still doing it. I think my overall mood is better, however I feel more dizzy. I will continue to the end as per instructions though and will report here of any findings.
