Defining stress as metabolic demand

New research links chronic stress, brain energy, and psychiatric conditions, including PTSD, depression, and bipolar disorder.

Stress doesn’t just impact your mood; it affects how your brain allocates energy. In this interview, Dr. Bret Scher sits down with Dr. Parker Kelly, a postdoctoral fellow at UCSF and the San Francisco VA, to unpack the Allostatic Triage Model of Psychopathology, a new framework proposing that psychiatric symptoms may emerge when the brain is forced to triage limited metabolic resources under chronic stress. Co-authored with mitochondrial researcher Dr. Martin Picard, this model could shift how we understand and treat mental illness.

In this conversation, you’ll learn:

• How stress drives brain energy dysfunction
• Why mitochondria and metabolism may be central to mental illness
• Which brain networks are impacted by energy deficits
• The role of predictability and routine in stress resilience
• How metabolic therapies like nutrition, sleep, and even psychedelics, may support brain energy regulation

This conversation bridges neuroscience, metabolism, and mental health, offering a unique and unifying lens on complex psychiatric conditions.
