Brain wave test may reveal if your antidepressant is working
NCT ID NCT00792168
First seen Jun 25, 2026 · Last updated Jun 27, 2026 · Updated 1 time
Summary
This study tested whether brain wave patterns (measured by QEEG) can predict how well people with major depression respond to the antidepressant venlafaxine (Effexor). Thirty-eight adults with depression received either venlafaxine or a placebo for a short time, then continued with open-label treatment. Researchers monitored brain activity and depression symptoms to see if early brain changes could forecast later improvement.
What this could mean
Our plain-language read of the trial. This is informational only — not medical advice or a prediction.
Active substance
venlafaxine (Effexor)
What this could lead to
If successful, this could help doctors use brain wave patterns to quickly tell if an antidepressant is working, potentially speeding up treatment decisions for depression.
What could go wrong
This is a small, early-phase study with only 38 participants, so results may not apply to everyone. The brain wave test (QEEG) is still experimental and not a proven tool for guiding treatment.
