Vestibular implant to improve thinking, navigation, and balance after inner-ear damage
Vestibular implant tested in patients with peripheral vestibular damage: effects on spatial orientation, navigation, and neuropsychologic function
A vestibular implant is being offered to people with severe inner-ear balance damage to help improve thinking, spatial orientation, and navigation.

What this research studies
If you join, doctors will implant a device that senses your head’s motion in three dimensions and delivers long-term stimulation to the balance nerves. You will take part in tests of spatial orientation, navigation, memory, and other thinking skills while the team tracks how stimulation affects those abilities. The researchers will also follow people with varying degrees of vestibular loss who do not get the implant to compare outcomes. The goal is to see whether prosthetic vestibular signals can reduce cognitive problems caused by severe peripheral vestibular damage and to better understand how balance input supports thinking.
Who could benefit from this research
Good fit: Ideal candidates are adults with severe, often bilateral, peripheral vestibular damage who experience balance-related cognitive problems and are eligible for implant surgery.
Not a fit: People with only mild vestibular impairment, cognitive problems from non-vestibular causes, or who cannot undergo surgery may not benefit from this approach.
Why it matters
Potential benefit: If successful, the implant could improve memory, spatial navigation, and daily function for people with severe vestibular loss.
How similar studies have performed: Prior vestibular implant and prosthesis work has improved eye movements, balance, and gait, but using implants specifically to improve cognition is relatively new.
