Not really. With treatment, a stuttering child after treatment who speaks normally can often regress into stuttering or some milder variation as a result of trauma or aging or a neurological condition such as Parkinson's. After I started stuttering in my 50s for the first time in my lifetime, I was surprised. People with Parkinson's are not known to stutter. Most of the known patients are Parkinson's diagnosed who used to be a stutterer and treated successfully at a very early age of which they usually have no memory or faint memory. I don't remember having stuttered in childhood and my mom does not recall having seen me stuttering. So I researched more and learned about acquired neurogenic stuttering which is something new AFAIK. Either way, my once successful career is down the tubes. Point is stuttering is not a sentence growing up. It can appear later on in life for any number of reasons. No reason I would buy into the MAGA propaganda.
