Brain-Computer Interface Gives ALS Patient Casey Harrell a New Voice

Casey Harrell has been living with amyotrophic lateral sclerosis (ALS) for several years. The condition has left them paralysed, but a brain-computer interface (BCI) has offered a new way to communicate. Harrell began using the BCI in 2023. The device enables them to form full sentences and interact with the research team. This technology has opened a direct line of communication where none existed before.

The team is now focused on refining the BCI further. Their next goal is to restore Harrell’s original voice, bringing back a personal element lost to the disease. The BCI has already transformed Harrell’s ability to engage with others. Ongoing improvements to the system could soon return their natural voice. This development marks a significant step in assistive technology for ALS patients.
