Effect of HF rTMS on Serum BDNF in Cocaine Use Disorder

Effects of 5-Hz Repetitive Transcranial Magnetic Stimulation on Serum Brain Derived Neurotrophic Factor and Clinical Variables in Cocaine Use Disorder

102 participants

Start Date

Study Type

INTERVENTIONAL

Conditions

Cocaine Dependence

Summary

This study aims to explore the effect of 5-Hz rTMS over the left dorsolateral prefrontal cortex on the BDNF, craving and cognitive function. This study will be longitudinal, with a short-term double-blind placebo-controlled phase consisting of 20 rTMS sessions and a long-term phase, consisting of 2 weekly sessions for 12 weeks. Participants will be clinically assessed pre-treatment (T0), after 20-sessions phase (T1) and after 12-weeks phase (T2) by an interview about psychiatric symptoms. Also, blood will be obtained in the same T0, T1 and T2 to peripheral levels of BDNF determination. Cognitive state will be measured at the same time-points (T0, T1, T2) by paper-pencil and computerized neuropsychological assessment. Researchers will compare active rTMS versus placebo 5 Hz-rTMS on described variables. Additionally, a comparative group (without rTMS intervention) will be included to equivalently measure described variables during periods without cocaine consumption.

Interventions

DEVICErTMS

Repetitive TMS will be administered by a MagPro R30 stimulator and an active/placebo MCF-B70 A/P coil. All participants will use two surface electrodes to simulate rTMS skin sensations near to stimulation site. rTMS/sham conditions will be double-blinded by a USB stick. The USB contains the information about rTMS/sham condition and this is not available to the stimulator operator. Parameters of rTMS were previously described.
