Investment surges, hurdles and emerging innovations in neuroscience

Innovation in neuropsychiatry is reviving after 40 years of dormancy, with recent approvals like Bristol Myers Squibb’s Cobenfy and Sage Therapeutics’ Zurzuave. Large Phase III studies on psychedelics aim to shift from anecdotal to evidence-based treatments. Challenges include high costs of Phase III trials and lack of effective animal models for CNS disorders. Investment in neuroscience is cyclical, with a need for better patient selection and biomarkers. Infrastructure and less intrusive diagnosis methods, like blood-based biomarkers, are crucial for tackling neurodegenerative diseases. AI and analytics advancements could improve diagnostic efficiency and patient targeting, despite regulatory hurdles and mixed public perception in neuropsychiatry.
