Addictions: Cocaine Use

rTMS in cocaine use disorder: neuromodulation of impulse and craving through prefrontal cortex targeting.

Cocaine Use Disorder (CUD) is a serious neuropsychiatric condition characterized by compulsive substance seeking, intense craving, loss of control, and repeated relapse despite negative consequences. No pharmacological treatment has received regulatory approval for CUD to date — a gap that rTMS is beginning to address with growing evidence. Read more about how rTMS works.

Why it matters

Cocaine addiction is associated with profound dysfunction of the prefrontal cortex (PFC), the structure that exerts executive control over behavior. DLPFC hypofunction leads to impaired inhibition of the urge to use. The lack of effective pharmacotherapy makes neuromodulation techniques particularly relevant: rTMS may help restore prefrontal executive control and reduce craving. Learn more about cost and procedure for addictions.

Mechanism

  • Neurobiology of cocaine addiction: Cocaine blocks dopamine reuptake in the nucleus accumbens (NAcc), leading to hyperdopaminergic activation of the reward circuit, gradual PFC hypofunction, and impaired executive control.
  • rTMS target: High-frequency stimulation (HF, 10–20 Hz) of the DLPFC may restore prefrontal activity and strengthen top-down inhibition of the craving circuit. As in every protocol, motor threshold measurement is required.
  • Craving provocation: Craving provocation before the session, such as cue exposure, may enhance rTMS effectiveness because the activated addictive circuit is more vulnerable to neuromodulation.
  • Reward-circuit plasticity: rTMS induces LTP-like restoration of neuroplasticity in the frontostriatal circuit, reducing long-term sensitivity to craving.

Clinical significance

The key randomized controlled trial by Terraneo et al. in 2016 showed a significant reduction in cocaine use and craving in patients receiving HF-rTMS over the DLPFC compared with conventional treatment. Later studies, including Bolloni et al. and Antonelli et al., confirmed craving reduction, with more moderate results for long-term abstinence. rTMS is integrated as an adjunctive intervention within comprehensive addiction treatment programs. It does not replace psychosocial interventions, but it may strengthen the executive control that supports them.

Explicit relations (Entity Graph)

  • Cocaine Use Disorder (CUD) neurobiological substrate: hypofrontality involving DLPFC + hyperdopaminergic activation of NAcc.
  • Main rTMS target in CUD: left DLPFC, HF 10–20 Hz.
  • HF-rTMS over DLPFC action: restoration of frontostriatal connectivity and reduction of craving.
  • Craving provocation enhances rTMS effectiveness in CUD.
  • CUD pharmacotherapy: no FDA/EMA-approved medication.
  • rTMS for CUD: emerging evidence.
  • rTMS for CUD is integrated into comprehensive addiction-treatment programs, including psychotherapy and rTMS.
  • CUD is associated with dysfunction of the default mode network and salience network.
