Sound Waves Zap Delusions in Schizophrenia Trial
2 Nov
Summary
- Focused sound waves showed a small reduction in delusions.
- A single 10-minute treatment lasted up to a week.
- Larger studies are needed to confirm safety and effectiveness.
Researchers have explored a novel approach using focused sound waves to alleviate delusions in patients with schizophrenia and schizoaffective disorder. The technique, known as transcranial ultrasound stimulation, employs gentle sound waves to modulate brain activity without surgical intervention.
A recent study involving 10 participants, whose symptoms persisted despite medication, demonstrated promising initial results. A single, 10-minute session directed towards the globus pallidus internus deep within the brain resulted in a small, yet measurable, reduction in delusion severity that persisted for up to a week.
Participants experienced an average drop of 1.2 points on a delusion severity scale following the active treatment, compared to a slight increase of 0.4 points after a sham procedure. Mild and transient side effects such as headaches and tiredness were reported.
Future research aims to refine the technique by adjusting sound wave intensity using advanced brain imaging. However, given the small sample size, extensive studies are crucial to determine the treatment's overall safety and effectiveness over extended periods.
