Automated Sleep Detection in Movement Disorders Using Deep Brain Stimulation and Machine Learning.

Background Objectives Methods Results Conclusion Automated sleep detection in movement disorders may allow monitoring sleep, potentially guiding adaptive deep brain stimulation (DBS).The aims were to compare wake‐versus‐sleep status (WSS) local field potentials (LFP) in a home environment and develop biomarkers of WSS in Parkinson's disease (PD), essential tremor (ET), and Tourette's syndrome (TS) patients.Five PD, 2 ET, and 1 TS patient were implanted with Medtronic Percept (3 STN [subthalamic nucleus], 3 GPi [globus pallidus interna], and 2 ventral intermediate nucleus). Over five to seven nights, β‐band (12.5–30 Hz) and/or α‐band (7–12 Hz) LFP power spectral densities were recorded. Wearable actigraphs tracked sleep.From sleep to wake, PD LFP β‐power increased in STN and decreased in GPi, and α‐power increased in both. Machine learning classifiers were trained. For PD, the highest WSS accuracy was 93% (F1 = 0.93), 86% across all patients (F1 = 0.86). The maximum accuracy was 86% for ET and 89% for TS.Chronic intracranial narrowband recordings can accurately identify sleep in various movement disorders and targets in this proof‐of‐concept study. © 2024 The Author(s). <italic>Movement Disorders</italic> published by Wiley Periodicals LLC on behalf of International Parkinson and Movement Disorder Society.
