I recommend scheduling an appointment with a neurologist for a thorough examination to assess the possibility of any brain damage. *"Some drugs and substances can make seizures more likely. These include painkillers (like certain anti-inflammatory drugs, tramadol, and others), antibiotics (penicillins, cephalosporins, quinolones), antidepressants, and various other types of medications. Certain psychotropic drugs, like clozapine and tricyclic antidepressants, may especially increase the chance of drug-induced seizures. Newer psychotropic medications seem to have a lower risk of causing seizures. For example, bupropion, a type of antidepressant used to quit smoking, may provoke seizures in about 1 in 1000 patients. Additionally, some traditional remedies, like Chinese herbal treatments, Indian traditional remedies, and red flower oil, may also lead to seizures"* ([source](https://jnnp.bmj.com/content/75/suppl_3/iii2)) * More [info](https://www.google.com/search?q=medication+causes+neurological+damage) * *"The term neurogenic stuttering can be defined as a subtype of acquired stuttering in which disfluencies are associated with acquired* ***brain damage*** *in a person who did not stutter before brain damage. Neurogenic stuttering is most often the result of traumatic brain injury and stroke or other structural abnormalities in the brain.*" ([source](https://www.ncbi.nlm.nih.gov/pmc/articles/PMC8802677/))
