This thesis develops a novel framework that integrates mechanistic models and insights with machine learning (ML) to address neurological disorders by diagnosing them early and accurately, developing treatments, and improving our understanding of their underlying biology. Mechanistic insights and models express known disease-related biological processes either implicitly or explicitly as mathematical relationships amongst pertinent variables. These implicit/explicit relationships mitigate the noise in multi-modal data and help ML models efficiently extract unknown relationships related to the disease. Thus, our approach provides a holistic view of dynamically evolving, multi-scale, complex diseases in the face of unknown biological relationships by overcoming data-related challenges such as partial observability, high dimensionality, noise, and limited data. Our approach led to novel ML-based techniques that (i) work well with limited data, (ii) express and learn complex relationships, and (iii) capture causal relationships, which enabled diagnosis and in silico exploration of treatments. This thesis exemplifies the proposed framework by addressing clinically important problems in (i) Alzheimer’s disease (AD) and (ii) epilepsy. (i) Integrating mechanistic models with reinforcement learning (RL) enabled early diagnosis of individuals at risk of future cognitive decline by predicting personalized 10-year AD progression. (ii) We developed a unique mechanistic state-space model of epilepsy that could forecast seizures several days in advance and demonstrated its utility for designing RL-based adaptive brain stimulation to alleviate seizures.
