For as long as i can recall i have been susceptible to throat infections such as tonsilitis and recurring sinus problems; These have been one of those fixtures of life that we learn to deal with but over the past 18 months maybe more it has been a constant cycle of infection>antibiotics>re-infection with a pattern of diminished mental capacity cumulating with each reinfection, this diminished capacity manifests itself as a marked exageration of my ASD (unable to mask, repetitive behaviours increase, anxiety through the roof, clumsier etc) and reduced intelligence (maths goes out of the window, memory goes, i can't think of words, can barely speak) my GPs advice? Give up smoking.
Then about a month ago maybe more (sketchy memory during infection) a post on reddit caught my attention which lead to me posting this.
I went to my GP with the most pertinent, recent papers regarding PANDAS and he was open to the information and gave me another 14 day prescription for antibiotics. At around day 10 i started to feel the mental fog receeding and could feel the physiological (biochemical really) changes in my brain but i knew the strep hadnt gone and reinfection would soon occur so i called the GP for a phone consult and another 7 days antibiotics was prescribed. As the fog was lifting i could feel the mental acuity slowly returning so i set about to really understand what is going on.
The first stumbling block to me is the name
P.A.N.D.A.S; Paediatric Autoimmune Neuropsychiatric Disease Associated with Strep
Pediatric? Huh? I'm 42.
I was pretty sure what was occuring to me was the same as PANDAS, so the next step was to understand what the actual process that leads to PANDAS is and to understand WHY it is affecting me.
The first step is a strep infection (group A strep is mainly documented but B is also at play), generally tonsilitis/pharyngeal infection, this colony starts to produce a group of cells called Th Cells (T helper), specifically Th17, the strep colony expands from the tonsils/pharynx to the nasal cavity and colonises that space, still pumping out the Th17 cells, these Th cells travel from the olfactory bulb down the axons of Olfactory Sensory Neurons crossing the Blood Brain Barrier (B/BB). When Th17 crosses the B/BB it produces interleukin 17 (IL17) which binds to proteins in the brain causing the receptors to misfire, IL 17 also has another function - it further opens the B/BB to more Th17, reinforcing the cycle¹. This series of events causes the basal amygdala to become inflamed as part of the auto immune response³. Antibiotics kill off the strep but the IL 17 and Th17 remain, albeit in lesser numbers; until reinfection when it all starts again but more intensely.
But still, you're 42.
The ASD brain has what is known as a 'permissive Blood Brain Barrier'³. A typical brain becomes less permissive in its prime so post adolescence PANDAS is less likely to occur in NTs, however i think that for those of us on the spectrum it is just put down to our ASD and never properly looked at nor treated.
I have subsequently presented my GP with the research around this and a referral to an immunology department has been made.
This is not a suggested cause for ASD, i have always been an aspie always will be, what this is though is a hidden, underlying condition that massively exacerbates a current condition
I believe this discovery to be significant, this is not my discovery i am merely piecing research together, but it is none the less a lightbulb moment.
As an aspie i find the periods of infection to be the most scary, debilitating experiences i have ever had, i cannot comprehend how this would affect someone non verbal, i have to say in the most strongest terms if you/they have a history of throat infections ESPECIALLY with sinusitis, which have an observable effect upon your/their behaviour then read about PANDAS and the papers referenced at the bottom.
¹ Group A Streptococcus intranasal infection promotes CNS infiltration by streptococcal-specific Th17 cells.https://www.ncbi.nlm.nih.gov/pubmed/26657857
² Blood–brain barrier and intestinal epithelial barrier alterations in autism spectrum disorders https://www.ncbi.nlm.nih.gov/pmc/articles/PMC5129651
³ Pediatric Autoimmune Disorders Associated with Streptococcal Infections and Tourette's Syndrome in Preclinical Studies https://www.ncbi.nlm.nih.gov/pmc/articles/PMC4928151
I have read a lot of research to come to this conclusion, these are a sample that cover what i have said in less papers, if you require more on specifics i can probably guide you in the right direction.
PANDAS occurs in adults. Period.

"In Medical School the first lecture on psychiatry always addresses the obligation of the psychiatrist to look for or rule-out underlying organic (medical) factors that may cause or exacerbate a psychiatric problem or presentation. This is reiterated in residency. And in the first chapter of every general psychiatry textbook. It doesn’t suggest that every patient be examined or “worked-up” for every conceivable diagnosis known to man. Where is the problem?
Here is the part where I will be called boasting and conceited. Why, in 35 years of practice have I diagnosed 19 cases of Porphyria, 10 cases of Neurosyphilis, hundreds of cases of thyroid disease, epilepsies, brain tumors, hormonal and other metabolic aberrations, and now more than 100 cases of PANDAS? Well…I looked." - Jory Goodman M.D.
Not to cast dispersions on this guy but read the reviews from his patients. I wonder why he manages to diagnose so many of the rare disorders that he claims to specialise in.
I'm probably wrong but.. why is most of the info being written by a Beverley hills shrink?
Yes, I know. I don't like posting from articles for that same reason. But the general field of research is sound.
Sometimes articles are easier to digest. before you look at https://www.panspandasuk.org/
