BRAIN - IMMUNE CONNECTIONS in HEALTH & DISEASE Esther M. Sternberg, M.D., Director, Integrative Neural Immune Program National Institute of Mental Health/NIH Author: The Balance Within The Science Connecting Health and Emotions
There are many parts to “Stress”: • Initiating event • Perception • Response • Effect
Emotions Disease
Emotions Health = Balance Disease

IL IL Antibodies The immune system signals the nervous system via many routes. CYTOKINES Nerve cell death and survival
Infectious • NeuroAids • Toxoplasmosis Degenerative • Alzheimer’s Inflammatory/autoimmune • Multiple Sclerosis Vascular • Stroke Traumatic • Nerve trauma Diseases in which Cytokine-Induced Neurodegeneration May Play a Role:

Cytokines can signal the brain: • Leaky areas in BBB: • OVLT, ME • Signaling via Vagus • Active Transport • Second Messengers: • NO, PGs

“The chief and primary cause of …the very rapid increase of nervousness is modern civilization, which is distinguished from the ancient by these five characteristics: steampower, the periodical press, the telegraph, the sciences and the mental activity of women.” American Nervousness, Its Causes and Consequences, George M. Beard, 1881
Hans Selye (ca. 1960) Stress=non specific response of the body to any demand.
The stress response is more specific than Selye predicted. D. Goldstein et al.; P. Sawchenko et al.
There Are Many Kinds of Stress. • Psychological – performance, hierarchy, relationship, loss • Physical– pain, exercise • Physiological – infection, disease, nutritional deprivation, sleep deprivation, hemorrhage, hypoxia, heat/cold

We Can Learn to Control Some Parts of Our Stress Response. • Training/practice • Biofeedback • Stress reduction programs • Meditation/Yoga/Prayer • Psychotherapy • Exercise • Social support • Lifestyle change (Mediterranean)
Stressors Have Different Effects Depending on: • Dose • Pattern • Duration • Gender
