Transcranial stimulation doesn't prevent post-op delirium in seniors

A new study in Deutsches Ärzteblatt found that a single dose of transcranial electrical stimulation (tES) after major surgery generally didn't prevent post-operative delirium in older patients. However, the Greifswald-based research team did see some benefit for those who underwent longer surgical procedures. It looks like the brain fog after surgery is tougher to beat than a simple electrical pulse.
