A new non-invasive treatment using sound waves has demonstrated success in reducing delusions among schizophrenia patients in a groundbreaking study at NYU Langone Health, offering hope for individuals whose symptoms persist despite medication.

Ten-Minute Treatment Targets Deep Brain Region

Researchers tested transcranial ultrasound stimulation on ten patients diagnosed with schizophrenia or schizoaffective disorder. The experimental technique uses focused sound waves to reach the globus pallidus interna, a small region deep within the brain that regulates movement, thinking, and emotions. This area has traditionally been difficult to access without invasive surgical procedures, making the non-invasive approach particularly significant for patient safety and treatment accessibility.

The single ten-minute treatment session produced measurable improvements. Patients experienced an average reduction of 1.2 points on a seven-point clinical scale used to measure delusions. While the number appears modest, control patients who received a placebo treatment showed no improvement whatsoever, confirming the ultrasound treatment’s effectiveness. Delusions are false beliefs that individuals with schizophrenia perceive as reality, often severely impacting their daily functioning and quality of life.

Minimal Side Effects Reported

Lead researcher Wei Qi, a clinical assistant professor of psychiatry at NYU Grossman School of Medicine, described the findings as early evidence that ultrasound can safely adjust brain circuits linked to psychosis. Side effects remained mild and temporary, including headaches, fatigue, and brief increases in psychotic symptoms that resolved quickly. The safety profile represents an important advantage over more invasive interventions currently available for treatment-resistant schizophrenia.

What This Means for Patients

The research, published October 20 in the journal npj Acoustics, addresses a critical need in mental health treatment. Many schizophrenia patients continue experiencing debilitating symptoms despite taking psychiatric medications, limiting their ability to work, maintain relationships, and live independently. This ultrasound approach offers a potential alternative or supplementary treatment that avoids surgery and requires minimal time commitment. Further research with larger patient populations will determine whether the treatment’s benefits extend beyond single sessions and how long improvements last. The findings represent a meaningful step toward expanding treatment options for this severe chronic mental disorder affecting millions of Americans and their families.
