Major Depressive Disorder (MDD) affects a significant percentage of the national population (17-20%) in 2:1 ratio in women compared to men. Repetitive Transcranial Magnetic Stimulation (rTMS) is an effective neuromodulation technique for the treatment of Major Depressive Disorder and it has demonstrated favorable clinical effects when applied over the Left Dorsolateral Prefrontal Cortex (LDLPFC); however there is evidence that other areas of the prefrontal cortex such as the Dorsomedial Prefrontal Cortex (DMPFC) could be ideal for rTMS treatment targets during the presence of MDD, given its association with deficient cognitive processes during the course of the illness. There is also evidence of the use of 5Hz frequency with the same clinical effectiveness from other frequencies such as 10 Hz and 20 Hz when applied to the LDLPFC. However, there are no current research that have addressed the use of this frequency on DMPFC.
This study evaluates the efficacy of 5Hz repetitive Transcranial Magnetic Stimulation (rTMS) over Left Dorsolateral Prefrontal Cortex and Dorsomedial Prefrontal Cortex on Major Depressive Disorder (MDD).
