PANS/PANDAS Symptoms: What You Need To Know

PANS/PANDAS Symptoms in My Family

If you have a child and haven’t heard of PANS/PANDAS and the symptoms associated with this devastating syndrome, it is very important that you do. Last week, I shared the story of my then 12 year-old daughter’s battle with PANS (Pediatric Acute-onset Neuropsychiatric Syndromes). Her sudden-onset panic, fear, terror and severe separation anxiety stopped our family’s life that summer.

PANS/PANDAS, OCD, Strep, Pneumonia

We felt as though we had lost our daughter. The joyful, fun-loving, social butterfly that we knew had been kidnapped by what we soon learned was a very common bacterial infection. Mycoplasma or in layman’s terms, pneumonia. You can read more about our daughter’s story here.

Bacteria Playing Hide & Seek: PANS

Here is my attempt to explain how a bacteria such as mycoplasma, which causes pneumonia, can cause PANS/PANDAS. The symptoms that this bacteria and others cause includes drastic emotional or behavioral changes.

Basically, these bacteria (STREP or mycoplasma, for example), play Hide & Seek within the body. They actually imitate the healthy cells within the body. They “hide” while pretending to be healthy body cells. In the time that these bacteria are hiding, they multiply in secret. The invaders grow and grow until they are finally found by the body’s immune system. Our immune system actually attacks the healthy cells that the infections have been mimicking in secret.

What Are The Symptoms of PANS/PANDAS?

Devastatingly, at that point, the child’s behaviors and emotions take a drastic turn for the worst causing frightening emotional and behavioral symptoms:

  1. OCD (this can present as repetitive distressing thoughts)
  2. Anxiety
  3. Depression
  4. Severe opposition
  5. Aggression
  6. Handwriting deterioration
  7. Sleep disturbances
  8. Obsessions about food
  9. Hyperactivity and sudden ADHD-like symptoms
  10. and more…

Forced to Play A Game

This forces parents and doctors to begin the game of Hide & Seek that they did not know they were supposed to be playing.

Adults finally seek out the cause of these severe changes in the child and then often find the bacterial culprit if the proper blood workups are performed.

Very often, doctors are not well-versed in the diagnostic criteria for PANS/PANDAS.


Specifically referring to the STREP bacteria, WebMD describes it this way:

An infection causes your immune system to attack your body’s healthy cells, in this case, cells in the brain. The strep bacteria disguise themselves to look like normal cells. When the immune system eventually finds and fights them, it sometimes also fights the cells that the strep is imitating.

Journey from PANS/PANDAS Symptoms to Diagnosis

Today, I would like to share the story of a sweet friend of mine. She has and is currently navigating this incredibly rocky road with her own son, who has the trifecta diagnosis of PANS/PANDAS and AE.

According to, AE, Autoimmune encephalitis is:

Autoimmune Encephalitis

Another way to think of PANS PANDAS, as well as any neurodevelopmental disorder such as autism, ADD/ADHD, Sensory Processing Disorder and even learning disabilities, is that these disorders may fall under the larger umbrella of autoimmune encephalitis (AE).

Autoimmune encephalitis is a disorder in which the immune system attacks the brain, impairing function.

I am honored to have Heather share her story with you in the hopes that more moms are able to access the appropriate diagnosis for their children who are suffering at the hands of this life-altering and debilitating illness.

Behavioral Changes: Wrong Diagnosis

Heather’s Story of PANS/PANDAS

It was about 3 years ago when my then 4 year old started changing. We were getting calls from preschool about behavior challenges they were having with him and thought it was best he be evaluated for social/emotional and academic delays. This came as a bit of a punch in the gut as I knew my child had been ahead before this and we always watched him so closely as we have another child on the spectrum.

So why now?

What changed?

Had I missed something?

Could I have been in denial for 4 years?

Therapies For Kids With “Behavioral” Problems

So we navigated through this new journey of many evaluations, Occupational Therapy, Speech Therapy, specialty Doctor appointments and many diagnoses……. Many!  We would enter one of our toughest seasons yet in parenting. I mean parenting has never been easy and fun for us with our other children, but this season we were entering was the biggest heartache of them all.

Entire Family Impacted by PANS/PANDAS

As we navigated our way through a very dark valley of medical appointments, wrong diagnosis, the school system, our home life and watching him deteriorate rapidly.  I began doubting everything especially the vision I knew God had shown me. I was questioning everything I once knew to be true!


PANDAS/PANS: Finally It Made Sense!

Then there it was one night, almost 2 years later. It was staring back at me on a screen.  All my child’s symptoms listed. Everything.  Our nightmare finally given a name.  PANDAS. PANS.

How had we missed this?

Why was this not discussed, mentioned?

Why am I the one figuring this out?

I’m just a mom and I am discovering what this is……




  • ADHD / ODD
  • Regressive Autism / PDD-NOS
  • Sensory processing disorder
  • Severe Anxiety with OCD – RAGE
  • Bi-polar disorder with hallucinations
  • Anorexia Nervosa

This is PANDA’s… PANS… Our HELL in 1 word, all of our symptoms.  And this is our HOPE! This is our journey to healing!

If you have child with multiple diagnoses please take some time to research PANS/ PANDAS.  To learn more about Heather’s story as she navigates her son’s continuing battle with PANS/PANDAS/AE, check out her Facebook page. Trust in the Journey.

  1. I have never heard of PANDAs/PANS. Thank you for adding to my knowledge. I hope I never have to use that knowledge but at least I know about it if I notice the symptoms.

    • Yes! Hoping you don’t ever need to know about it. I had no idea until it hit my home two summers ago. Just good to spread awareness so kids can get early diagnosis and treatment. It’s so much harder to knock it out when it has gone undiagnosed for too long. Earlier diagnosis, better prognosis. Thanks, Rachael!! 🙂
