Transcranial Magnetic Stimulation (TMS), a non-invasive neuromodulation technique that has gained attention for its potential in treating cocaine use disorder (CUD).

The Mechanism of TMS in Cocaine Addiction

Using brain scans of Cocaine addicts showed alterations in brain circuitry, particularly in the prefrontal cortex (PFC) and the limbic system, which are involved in decision-making, impulse control, and reward processing. Long term abuse of cocaine disrupts these circuits, leading to compulsive drug-seeking behaviors and frequent relapse.

TMS targets these disrupted circuits by modulating the activity in the PFC. By delivering repeated magnetic pulses to the PFC, TMS can potentially restore normal functioning in this area, reducing cravings and improving self-control. This neuroplastic effect makes TMS a compelling candidate for treating cocaine addiction.

Recent Research and Clinical Trials

The last few years have seen a surge in research exploring TMS as a treatment for cocaine addiction, with several studies yielding encouraging results.
1. Double-Blind, Randomised Controlled Trials: One of the most significant studies was conducted in 2021, where researchers applied high-frequency TMS to the dorsolateral prefrontal cortex (DLPFC) of individuals with cocaine use disorder. The results showed a significant reduction in cocaine use and cravings compared to the placebo group. This study paved the way for more extensive clinical trials.
2. Personalised TMS Protocols: Recent advancements have focused on tailoring TMS protocols to individual patients. A 2022 study explored the efficacy of personalised TMS, where the stimulation parameters were adjusted based on each patient’s brain activity patterns. The findings indicated that personalised TMS could enhance treatment outcomes, particularly in patients with severe addiction.
