Key Finding
Scalp acupuncture significantly outperformed Western medication for poststroke depression across effective rate, Hamilton Depression Scale scores, and neurological recovery, while producing approximately 88% fewer adverse events.
After a stroke, many people experience depression that can make it harder to recover physically and mentally. This condition, called poststroke depression (PSD), affects a significant number of stroke survivors and can slow down rehabilitation. Researchers wanted to know whether scalp acupuncture — a specialized technique that targets specific zones on the scalp corresponding to different brain regions — could help people recover from PSD more effectively and safely than standard Western medications.
To find out, scientists reviewed 14 carefully designed clinical trials that compared scalp acupuncture to Western medicine treatments for poststroke depression. Some trials used scalp acupuncture alone, while others combined it with a related technique called electroacupuncture, which adds gentle electrical stimulation to the needles.
The results were encouraging. Patients who received scalp acupuncture were significantly more likely to show meaningful improvement in their depression compared to those taking Western medications. Their scores on a standardized depression rating scale (the Hamilton Depression Scale) improved more, and they also showed better recovery of neurological function — meaning their brain and body coordination improved more as well. Perhaps most strikingly, the scalp acupuncture group experienced far fewer side effects and adverse events than the medication group, with roughly 88% fewer unwanted reactions reported.
For stroke survivors struggling with depression, these findings suggest that scalp acupuncture could be a safe and effective option, either on its own or alongside other treatments. It may be particularly appealing for patients who are sensitive to medications or concerned about side effects.
The researchers note that more large, high-quality studies are still needed to confirm these findings, so it is important to discuss all treatment options with your healthcare provider. If you are interested in exploring scalp acupuncture, seek out a licensed and experienced acupuncture practitioner with training in neurological conditions.
This systematic review and meta-analysis evaluated the efficacy and safety of scalp acupuncture (SA) — including SA combined with electroacupuncture (EA) — versus Western pharmacotherapy for poststroke depression (PSD). Fourteen RCTs were included (10 SA-only, 4 SA plus EA), with data pooled using RevMan 5.4.1 and Stata 15.0. SA demonstrated a statistically significant advantage in overall effective rate (RR = 1.09, 95% CI [1.02, 1.16], P = .008), Hamilton Depression Scale scores (MD = -2.29, 95% CI [-3.88, -0.70], P = .005), and neurological deficit scores (MD = -3.06, 95% CI [-5.91, -0.21], P = .04). Critically, the adverse event incidence was markedly lower in the SA group (RR = 0.12, 95% CI [0.05, 0.29], P < .00001). Clinical takeaway: SA appears to offer superior depression reduction, neurological recovery, and tolerability compared to standard pharmacotherapy in PSD, supporting its integration into post-stroke rehabilitation protocols pending confirmation by larger, higher-quality RCTs.

📌 A meta-analysis of 66 RCTs found that acupuncture combined with SSRIs or SNRIs significantly reduced depression severity and increased remission rates by nearly 60% compared to antidepressant medication alone.
📌 Electroacupuncture significantly reduced depression scores (HAMD and SDS), improved stroke recovery and daily functioning, and raised serotonin levels and cerebral blood flow in 853 post-stroke depression patients across 11 randomized controlled trials.
