If it's slow onset and not brain trauma or brain injury suffered from a stroke or accident, absolutely. But I wouldn't use the word 'cure' as it's not a disease and it sets a wrong expectation of there being a solution where the proper brain structure and pathways get instantaneously replenished and back in order. It must be noted stuttering set its roots for years and years. A reversion process should at least take months. We all know the experience of having stutter spring up to mind before speaking. Yet, in days when our speech is better the thought doesn't elicit as much negative emotion in us and we quite easily dismiss or override it. In other days, the same thought feels impossible to overcome. There is a reality where this is brought in conscious control. And the more in control over long spans of time, the more negligible stuttering becomes altogether. A pill that cures stuttering is a fairy tale because expecting a pill to successfully target the 'roots' I mentioned without bombing its way through all other proximal but unrelated brain pathways is simply ridiculous. Cancer has had all the research funding and effort in the world and chemotherapy still fails to effectively target the cancerous cells without destroying the healthy ones too. On the other hand, what I'm saying is an extremely likely reality. I might say tangible even, because I'm living it.
