Patients experience profound life improvements
Patient testimonials reveal technology’s human impact beyond clinical metrics. Casey Harrell, unable to speak due to ALS, described his pre-BCI state: “Not being able to communicate is so frustrating and demoralizing. It is like you are trapped.” The BrainGate speech interface changed everything—he cried with joy seeing his thoughts appear as words, finally communicating with his young daughter who had never heard him speak. newsUC Davis
However, research on six seizure-prediction BCI patients revealed complex psychological impacts. While some experienced increased sense of control and self, others reported “radical distress, feelings of loss of control, and rupture of patient identity.” These findings prompted calls for psychological preparedness protocols in future trials.
Patient selection criteria vary by system but generally require stable medical conditions, strong support systems, and realistic expectations. Most trials focus on patients with ALS, spinal cord injury, or brainstem stroke causing severe motor impairment. NeurologyNih The relatively small patient populations—approximately 100 people worldwide with implanted BCIs—makes each participant’s experience invaluable for advancing the field. Technologyreview
