Biofeedback is the process of moderating, limiting or changing certain
physiological functions previously thought to be involuntary, such as
heart rate, blood pressure, brain waves, etc. For Epilepsy, a person
could be given extensive biofeedback training and taught behavioural
modification techniques through which he/she control certain
physiological functions related to seizures. Biofeedback training can
also be taught as a method of stress reduction. This in itself can
reduce the frequency of seizures in some persons with stress related
seizures. Further study is needed to ascertain the value of biofeedback
in the treatment of Epilepsy. Non-medical approaches may improve
seizure control in some persons, but should not be undertaken without
the knowledge of the physician prescribing the anti-convulsants. Under
no circumstances should anti-convulsants be stopped suddenly as this
may precipitate prolonged and life-threatening seizures.
