In this episode, I take a deep dive into how natural language processing (NLP) and machine learning are beginning to reshape neuropsychological assessment. Beyond the surface-level hype around AI, I explore what’s actually happening under the hood: how speech, language, and narrative data can function as digital biomarkers for conditions like ADHD, Alzheimer’s disease, and psychosis. Drawing primarily from a 2025 review in The Clinical Neuropsychologist, I walk through emerging research, practical implications for clinicians, and the ethical and methodological challenges we’ll need to confront as these tools move closer to real-world clinical use. Main Topics Covered 00:00: Why NLP and machine learning matter for neuropsychology right now02:15: Defining NLP, digital biomarkers, and what clinicians usually discard04:40: How linguistic, acoustic, and semantic features are analyzed06:30: ADHD applications: narrative coherence and executive functioning08:55: Alzheimer’s and MCI: voice biomarkers vs. traditional measures11:30: Task design and why speech prompts matter12:45: Psychosis and schizophrenia: quantifying disorganized speech15:30: Clinical tools, ambient AI, and the “human-in-the-loop” model17:45: Bias, privacy, test security, and ethical risks19:55: The future of neuropsych assessment and hybrid AI models Cool Things Mentioned The Testing Psychologist mastermind groups and business consultingReverb: the premier AI-powered report-writing platform for testing psychologistsBrittany Wolff’s source article: https://doi.org/10.1080/13854046.2025.2547934 Featured Resources I am honored to partner with two AMAZING companies to help improve your testing practice!
