About Altoida

We’re pioneering precision neurology by building the world's leading platform for reliable, accessible, affordable diagnosis and monitoring of neurological diseases.

Our Story

“My grandmother was born in a small village in Greece. When she was 70 and I was pursuing my degree in psychology, she started to repeat her own words. Soon after, she started to become lost in her home, the place that she loved most. In the later stages of what we knew to be Alzheimer’s, she started to forget my father’s face. What struck me most was how in the early stages, I was able to recognize that something was wrong, yet she passed all of the traditional cognitive exams with ease.

This drove me to engineer a virtual environment to assess the changes in brain health, both cognitive and functional, that I observed firsthand with my grandmother. I learned that exercises in a virtual environment open up an entirely new horizon of more meaningful measurements and data that can be acquired. From there, we spent 20 years of research to bring us to where we are today.”
