Behavioral control of intractable idiopathic seizures: I. Self-regulation of end-tidal carbon dioxide.
Eleven women and seven men with moderate to severe chronic hyperventilation and idiopathic seizures refractory to therapeutic serum levels of anticonvulsant medication were given diaphragmatic respiration training with percent end-tidal CO2 biofeedback. The training had a rapid correcting effect on their respiration, making it comparable to that of 18 asymptomatic control subjects. Ten of the seizure-group subjects were in the study at least 7 months and following treatment, 8 showed EEG power spectrum "normalization", restoration of cardio-respiratory synchrony (RSA), and their seizure frequency and severity were significantly reduced.
