Brain Defenders: Dr. David Perlmutter & Apollo Health

Protect Your Brain – Start Now

After decades of research and clinical experience, Dr. David Perlmutter’s forthcoming book, Brain Defenders, explores how metabolic dysfunction, inflammation, immune imbalance, and environmental exposures shape brain health — and what we can do about it.
The book highlights the importance of early biomarker and cognitive testing, including Apollo Health’s BrainScan™ and free Cq Assessment, to measure risk before symptoms begin.
BrainScan
BrainScan is a highly sensitive and simple blood test that combines the Plasma Phosphorylated Tau 217 (p-Tau 217), Glial Fibrillary Acidic Protein (GFAP), and Neurofilament Light Chain (NfL) tests to detect cognitive decline years before symptoms appear, offering a gentle alternative to spinal taps and costly PET scans. Available without a prescription, Apollo is offering this blood test at a discounted rate of $799, down from the original $1299. To learn more and order, select the button below.
Cognitive Quotient
The Cq, or Cognitive Quotient, is a cognitive assessment devised by Dale Bredesen, M.D., specifically to detect early signs of neurological degeneration. The Cq Assessment is comprised of the AQ-6 Questionnaire, a subset of the AQ-21 (a proven informant-based screening questionnaire for Alzheimer’s disease), and an abbreviated CNS Vital Signs assessment (that evaluates executive function, speed processing, verbal and visual memory). Your Cq score is a percentile based on how well you perform compared to age-matched peers. Select the button below to learn more and take the free Cq Assessment.
Brain Defenders
We’ve been fighting the wrong enemy. For decades, medicine has pointed its weapons at symptoms like memory loss, tremors, headaches, and lethargy, while ignoring the root causes of diseases like Alzheimer’s, Parkinson’s, and major depression. In Brain Defenders, neurologist Dr. David Perlmutter flips the script, exposing the real culprits: malfunctioning microglia, tiny immune cells that, when metabolically hijacked, go rogue and attack the very neurons they’re meant to protect.
With clarity and urgency, Dr. Perlmutter explains how a silent battle rages in the brain. Microglia can become either warriors of protection or agents of destruction—and the outcome depends largely on how we live.
