What if the roots of anxiety, depression, and early puberty trace back to the first years of life — and we've been asking the wrong questions?

In this episode, host Deborah Westphal sits down with Angarika Balakrishnan, PhD candidate at the Brenhouse Lab at Northeastern University, whose research links early-life adversity to long-term brain development, neuroendocrine disruption, and mental health outcomes.

Key Takeaways

• Early-life adversity is not a single variable — timing, type, and predictability each produce different biological signatures in the developing brain
• The CRHR1 receptor in the hypothalamus may be a targetable mechanism for preventing early-onset puberty and adolescent anxiety
• Exercise during adolescence could serve as a treatment paradigm for metabolic, immune, and cognitive outcomes linked to early stress
• Depression, anxiety, and PTSD share underlying circuitry — treating them as separate conditions has slowed progress
• Science rewards certainty over doubt, and that culture is driving a mental health crisis inside PhD programs
