Clinical Trial Summary

This project was developed to analyze the clinical, biochemical and functional impact of tDCS on depressive symptoms in participants with temporal lobe epilepsy, intending to collaborate directly in the development of new therapeutic strategies for participants with epilepsy and associated mood disorders. Another objective of this work is to add knowledge about biosafety, possible behavioral and electrophysiological effects of tDCS in participants with temporal lobe epilepsy. Depending on the findings, the study as proposed may provide immediate results for the care of participants with epilepsy.


Clinical Trial Description

Transcranial direct current stimulation (tDCS) has emerged as an alternative tool in the treatment of participants with mood disorders and may also benefit the treatment of participants with epilepsy. However, this therapeutic tool has been little explored in the treatment of mood disorders in participants with epilepsy. Considering these aspects, the main objective of this project is to study the safety and possible therapeutic effects of tDCS in depressive symptoms of participants with temporal lobe epilepsy. As secondary objectives, stands out the evaluation of the effects of this stimulation on the frequency of epileptic seizures and on electrophysiological and biochemical parameters in these participants. To do this, after performing semi-structured interviews to evaluate depressive symptoms, quality of life and sleep, participants with Temporal Lobe Epilepsy will be randomized into two groups: 1) intervention with tDCS in participants with Temporal Lobe Epilepsy and depressive symptoms (T) and 2) sham intervention in participants with Temporal Lobe Epilepsy and depressive symptoms (S). After studying and characterizing the behavioral, biochemical and electroencephalic patterns (EEG), the T group will be submitted to tDCS. The control group will perform the same assessments and the same preparatory procedures, but will not receive the electrical stimulus. Finally, in addition to the analysis of the electroencephalographic patterns of the two groups at the end of each session, the analysis of the brain-derived Neurotrophic Factor Neurotrophic Factor (BDNF) will also be performed, as well as a new clinical evaluation regarding the frequency of seizures and patterns of these participants through the same semi-structured interviews conducted initially. ;
