This observational study seeks to investigate the underlying processes of myasthenia gravis by employing multimodal monitoring techniques. By integrating digital biomarkers alongside clinical monitoring, we aim to enhance the detection of disease activity and establish correlations between digital measures, clinical scores and various questionnaires including sores on quality of life, sleep quality or activities of daily living. Primarily including patients treated with newly approved drugs, it aims at improving and monitoring the efficacy and safety of treatment and allowing a more individualized treatment.
