TL;DR
  • tDCS offers multiple treatment approaches for comorbid conditions. If you have both depression and ADHD, transcranial direct current stimulation can help mood symptoms and may provide some benefit for ADHD symptoms as well.
  • Depression treatment with tDCS is well-established. Strong clinical evidence supports tDCS for depression. The treatment protocol, electrode placement, and expected outcomes are clearly defined.
  • ADHD evidence is emerging but less conclusive. Research into tDCS for ADHD shows promise, particularly for attention and executive function. However, the evidence base is smaller and protocols less standardized than for depression. Flow is approved for depression treatment, not currently licensed for ADHD
  • Treating depression may indirectly improve ADHD symptoms. Depression worsens concentration, motivation, and executive function—symptoms that overlap with ADHD. Reducing depression can improve these areas regardless of direct ADHD effects.
  • Discuss both conditions with your treatment provider. If you have comorbid ADHD and depression, talk with your provider about realistic expectations for how tDCS might help each condition based on current evidence.

As some of the symptoms of ADHD overlap with the symptoms of depression, you might benefit from tDCS. Transcranial Direct Current Stimulation (tDCS) is a non-invasive treatment for depression which is entirely safe to use when you have ADHD.

Can tDCS help with ADHD?

tDCS is approved for depression and has the following benefits:

Improved attention
Enhanced emotional control
Reduced impulsivity

ADHD often involves disrupted brain connectivity, especially in the cingulate and prefrontal cortex, which are areas targeted by Flow with tDCS.

Flow is not currently licensed as a treatment for ADHD. As some of the symptoms of ADHD overlap with the symptoms of depression, you might benefit from tDCS.

What is tDCS?

tDCS uses mild electrical currents to stimulate the brain’s prefrontal cortex, a region involved in decision-making, focus, and emotional regulation. When used regularly, it can reduce symptoms of depression.

Flow Neuroscience’s tDCS headset is:

Portable and hands-free
Used at home without a prescription
Designed for consistent daily use
5x/week during activation, 3x/week afterwards

Should You Try It?

If you have depression and ADHD, tDCS can help. As always, consult your healthcare provider first. And know that combining tDCS with therapy, routine, and lifestyle changes offers the best long-term support.
