Do you feel like your child has been stolen from you, possibly overnight?

Watching your child suffer from PANDAS or PANS can be a heart-wrenching experience, but the good news is, there is hope for your child.

As a mother of children affected by PANS and a seasoned clinician, Dr. Jill Crista created this playbook to support your family’s journey.

This book is an absolute must-read if you’re seeking to engage every aspect of care for your child, leaving no stone unturned. This invaluable book offers much-needed resources and support, moving beyond hope to mastering effective, practical things to do.

PANDAS and PANS happen when infectious and environmental triggers cause total body immune confusion, which in turn targets a child’s brain.

This results in changes to how the brain works, thinks, processes information, and feels.

In her easy-to-read style, Dr. Crista brings validity to how mental health and physical health are intertwined. She teaches you how to use this connection to your child’s benefit.

Trained in integrative medicine as a Naturopathic Doctor, Dr. Crista skillfully weaves higher force medical interventions with supportive natural medicine into a safe, comprehensive approach.

PANDAS and PANS exemplify how a physical body problem can express as behavioral and mental health changes.

What Experts Are Saying

“Dr. Jill Crista has provided an amazing book for parents that outlines many underlying problems in the gut, immune and metabolic systems in our children. And she is so right, PANS & PANDAS are clinical diagnoses, not lab test diagnoses. Listening to our patients, our families and uncovering the underlying infection, like GABHS, in PANDAS and mycoplasma and viruses as well as pesticides, mold and toxins in PANS, is so key to helping these children. Dr. Jill has included much needed information on effective herbal antimicrobials and nutraceuticals. She has written an easy-to-read, enjoyable book that parents need to help navigate many of the chronic illnesses and autoimmune issues that our children experience.”

“The abrupt and dramatic nature of PANS/PANDAS often leaves parents and practitioners confused and unsure of what steps to take to help the beautiful and distressed child in front of them recover. In A Light in the Dark for PANDAS & PANS, Dr. Jill Crista shines the light of critical thinking and humor onto this much misunderstood topic. She includes the most up to date research and clinical experience to create the most comprehensive and actionable guide on this topic. She leaves nothing to chance, explaining everything in clear detail so you are able to understand what is going on and what steps need to be taken to get your child back. A true gem of hope and love.”

This last month when our family was sick with strep and the flu our son started flaring…the violence and major OCD came back with a vengeance. In the past, once a flare like this started, it would last for 3-6 months with little rest. I had discovered you and and your book a few weeks ago through a guest Podcast spot you did. We started using the combos and doses recommended for a flare and within 24 hours we saw HUGE relief. My son is not back to 100% but he is back to where he was before the flare PLUS he picked up a chapter book 3 days ago and started reading it out loud to us and has continued to do so each day. This is insane since he hasn’t gone to school in 3 years and struggles to do anything academic. In one Kindle download you gave me the formula and info I needed to treat my child- information I have searched for and spent tens of thousands of dollars to access for the past 5 years. Thank you for giving it all- for not holding back in your book, for just spelling it out so clearly so parents like me can immediately bring relief to our struggling child and prevent further trauma for our family.


Wish I had found this book sooner. I have read many books on the subject of pans/pandas in order to understand and help my son. But this book goes into what you can ACTUALLY do, eg, what you can actually buy and give and treat and how much wtc. Invaluable insight, easy to read…
