EFFECTIVENESS OF NEUROFEEDBACK ON FREQUENCY OF SEIZURE IN PATIENTS WITH REFRACTORY LEFT TEMPORAL LOBE EPILEPSY

Epilepsy is a brain disorder characterized predominantly by recurrent and
unpredictable interruptions of normal brain function called epileptic seizures. The aim of this study
was to investigate the effectiveness of neurofeedback on frequency of seizure in patients with
refractory left temporal lobe epilepsy.
Materials & Methods: This case study included pre test, post test and follow up phases. The sample
consisted of two patients with refractory left temporal lobe epilepsy selected by random sampling
method. The study is based on Applied Behavior Analysis (ABA) approach, and a multiple baseline
design. Accordingly, the baseline data for the first test could be started if the second test was still in
the baseline situation. Then the in next step, the second subject was allowed to receive intervention.
The checklist of symptoms and the frequency of seizure was used to collect data during the pre-test,
post-test and follow-up phases. Patients participated in 30 treatment sessions of neurofeedback for 8
weeks.
Results: Visual analysis graphs suggested that there were significant differences between variables in
intervention and baseline phases for each subject according to frequency of seizures. In other words,
the mean of frequency of seizures decreased significantly after intervention.
Conclusion: The results suggested that neurofeedback is effective in decreasing frequency of seizure
in patients with refractory left temporal lop epilepsy.
