Nevertheless, patients on anticonvulsants need careful medical management. Most of these patients are light sensitive. The first phase of the treatment desensitizes them to the light stimulation, at which time frontal EEG slowing is strongly decreased. The next phase of treatment involves systematic discovery and treatment of all other sites of EEG slowing on the scalp. There is no conscious learning or practicing involved.
Daily treatment is most effective and reduces total numbers of sessions needed.
Paralysis from stroke or spinal cord injuries does respond, but it takes hundreds of sessions. Since FNS is a non-psychotherapeutic procedure, it is always important for the patients to have competent, adjunctive psychotherapeutic treatment and support at a level commensurate with the seriousness of any behavioral problems. The treatment code for FNS is 90901.
