I have suffered from a cerebellar atrophy for the last 7 years or so. I had an MRI done and my neurologist showed me two fuzzy areas in my brain that he attributed to former strokes which may have caused a huge chunk of cerebellum to be cutoff from blood supply long enough to cause atrophy. I am now on my downtime from my second time trying Noopept and I will say the changes in my daily mobility and balance have been miraculous. I can take Noopept and within three days, I no longer suffer from my disequilibrium or anxiety and stress from fear of falling. I took it for a couple of weeks the first time and though I felt great on it after that first time, I discontinued use after my doctor recommended that I stop taking Dietary Supplements. Fortunately, that doctor moved away and my new doctor has been great at talking about Noopept with his pharmacist to clear it for me to use. I tried a 54-day course the second time around and everthing is testing out fine. Currently off of it for the downtime. I felt like an idiot for the first week or so. This concerns me enough to where I will not take it for the full 54 days this next time around. In fact, I think I'm going to save Noopept for those special occasions when excessive movement will be required: vacations, maybe some holidays....
