Portable brain‑stimulation device cuts addiction cravings in early trials
Researchers in Colombia have created a portable, non‑invasive brain‑stimulation device that delivers low‑intensity electrical currents through scalp electrodes. Preliminary clinical trials reported that participants receiving the stimulation experienced a significant drop in cravings for nicotine and cocaine.
The most common side effects were mild tingling or slight scalp discomfort, and no serious adverse events were recorded. Some participants also showed modest improvements in cognitive tasks linked to impulse control. The studies involved a small sample size, so larger trials are needed to confirm efficacy and safety.
