I am facing the same problem of stuttering

Levetiracetam

>After 12 weeks of levetiracetam therapy, we observed a decrease in seizure frequency, as well as a complete disappearance of stuttering. A recent neuropsychological follow-up showed improved results for the verbal fluency test, which assesses the speed of verbal oral production and is not a task of speech-motor dysfluency. The Category Fluency Test, which measures the quantity of words belonging to four specific semantic categories, showed normal results. The other cognitive results remained unchanged. Polygraph studies allowed us to rule out action palatal and oropharyngeal myoclonus 4 as the cause of stuttering.
Discussion.
The main causes of stuttering, which has been defined as associated with “emotional pain and social stigma,”5 are actually unknown. Nonetheless, some authors 6 observed changes in the perisylvian area of stutters’ brains that could conceivably cause abnormalities in stuttering (speech) motor output. Indeed, stutterers seem to initiate the motor program before the articulatory code is prepared. 6
Here, we provide evidence of the efficacy of levetiracetam on developmental stuttering. Although there is no clear explanation for levetiracetam efficacy, it is reasonable to assume that this antiepileptic medication might influence the metabolism of the language area, increasing verbal fluency, as already suggested for piracetam. Indeed piracetam improved the recovery of various language functions in patients with poststroke aphasia, and this effect was accompanied by a significant increase of task-related flow activation in the eloquent areas of the left hemisphere.
