Does this drug not harm psychogenic pseudoepileptic disorders?

You did not write what drug you are talking about. If you have Pregamid, please read on. I cannot find any information that Pregamid "harms" psychogenic pseudoepileptic disorders. If it was prescribed to a person with such a diagnosis, then perhaps due to the anxiolytic effect, since in seizures in this case have an emotional basis. Treatment of psychogenic seizures is based on psychotherapy and the use of selected psychiatric drugs. Pregamid also has indications in neuropathic pain and epilepsy.
