Insights into Public Attitudes Toward Neurotechnological Treatments for Brain Disorders

As neurotechnologies rapidly advance to address various brain-related conditions, understanding public perceptions of these innovative treatments is increasingly important. A recent study conducted by researchers at Mass General Brigham surveyed over 1,000 adults in the United States to explore how people view four different neurotechnologies aimed at treating severe mood, memory, and motor symptoms. The technologies examined included deep brain stimulation (DBS), MRI-guided focused ultrasound (MRgFUS), transcranial magnetic stimulation (TMS), and oral medications.

Deep brain stimulation involves surgically implanting electrodes into the brain, making it the most invasive option among those studied. MRgFUS is a non-invasive, 'incisionless' procedure that uses focused sound waves to target brain tissue. TMS is also non-surgical, employing magnetic pulses to stimulate nerve cells. Researchers varied the symptoms targeted—mood, memory, or motor impairments—and analyzed how perceptions differed based on these conditions.

Participants assessed each technology on benefits, risks, acceptability, and potential impact on personal identity, along with their likelihood of choosing these options if they experienced relevant symptoms. Results showed that pills were perceived as most beneficial, acceptable, and likely to be used, with 61% open to trying medication. Conversely, DBS was viewed as the most invasive and risky, with only 21% considering its use.

Perceptions also shifted depending on the symptom targeted. Treatments for motor symptoms, such as Parkinson’s disease, were seen as more acceptable and beneficial than those for mood disorders, which participants deemed more invasive and likely to alter personal identity. These findings suggest that public attitudes are influenced not only by perceptions of the procedures but also by beliefs about mental versus physical illness.

The study highlights the importance of transparent communication and ethical considerations in deploying neurotechnologies, as concerns about invasiveness and changes to self influence willingness to adopt these treatments. Future research aims to examine how perceptions interrelate and influence acceptance, supporting the development of neurotechnologies aligned with patient values. These insights are essential for clinicians, researchers, and developers to foster trust and devise strategies for effective integration of neurotechnological therapies.
