tDCS (Transcranial Direct Current Stimulation)
Low-intensity electrical neuromodulation via scalp electrodes, generally quieter and better tolerated than rTMS, with milder and more variable effects.
What it is & how it works
Low-intensity electrical neuromodulation delivered via scalp electrodes, using a constant weak current to modulate neuronal excitability beneath the electrodes. It is generally lower-intensity, quieter, and better tolerated than rTMS, though its effects are typically considered milder and more variable.
How it's done
Typically administered as outpatient sessions of roughly 20–30 minutes, often given daily or several times weekly over a defined course (commonly 2–4 weeks), sometimes paired with a concurrent task (e.g. a rehabilitation exercise) during stimulation, and delivered under clinical supervision.
Conditions it treats
Why Brain Bridge
Consistent with Brain Bridge's evidence-bounded positioning, tDCS is offered only where assessment supports it and always framed with individualized, non-guaranteed outcomes — one tool among several in a coordinated plan rather than a standalone offering.
Evidence & safety
Evidence base is condition-specific and still developing for several indications. Used within a supervised assessment and treatment plan. In autism, tDCS is an off-label use with early, developing evidence; it is considered only alongside core developmental therapy and after discussion with the family.

No. ECT uses a stronger current under general anaesthesia to deliberately induce a brief seizure; tDCS uses a much weaker, sub-sensory current that does not induce a seizure, requires no anaesthesia, and patients remain awake throughout.
Most people feel a mild tingling, itching, or warm sensation under the electrodes during the session. Reported side effects are generally mild and temporary, such as scalp irritation, headache, or fatigue, and serious adverse events are rare in the clinical literature.
