BrainDee is a wearable brain modulator designed to enhance the diagnosis and treatment of neural disorders. It offers a non-invasive, personalized approach with minimal side effects, aiming to improve the quality of life for patients. Its active scalp electrodes provide high-quality EEG recordings and can deliver transcranial electrical stimulation (DC, AC, RNS) without causing motion artifacts or interrupting the EEG recording. This capability allows neurologists to optimize stimulation locations and strategies by comparing EEGs before and after the intervention. Additionally, BrainDee incorporates AI algorithms for the automatic detection of pathological brain activities and ensures precise control over stimulation timing. While BrainDee was initially designed with a focus on movement disorders, it aims to expand its applications in the future for personalized brain modulation.
