Last month I posted an article on this website describing Diane, a teen-age girl suffering from anorexia nervosa. (1) As it turned out, she had Lyme disease and was coinfected with Babesia, Bartonella and Mycoplasma. She responded to antibiotics and three years later she still has no evidence of an eating disorder.
Dr. Nancy Brown, a colleague, was in my office during one of Diane’s appointments, and I commented to Nancy, “Wouldn’t it be great if we could test a group of people who suffer from anorexia nervosa for tick-borne infections?”
“Well,” she told me, “I’m the medical consultant at a residential treatment center for adolescents with mental health issues. Let’s see if I can get permission to do this.”
We did receive cooperation from the residential center. In addition, IGeneX Laboratory agreed to test a dozen patients free of charge for Lyme, Bartonella, and TBRF—tick-borne relapsing fever. Moleculera Labs also generously agreed to test our patients to the Cunningham Panel.
It was not difficult to get ten volunteers at the residential center. None had eating disorders, since the center was not equipped to deal with that, but all ten were diagnosed with DSM-5 Major Depressive Disorder, seven were additionally diagnosed with Generalized Anxiety Disorder, and three had made serious suicide attempts.
With the exception of one subject previously diagnosed with celiac disease, none had a known physical disorder. All of these teens had severe psychological dysfunction requiring intensive residential treatment—they could not hack it at home or go to school.
Here is what we found (2):
In all likelihood, nine of ten had antibodies to tick-borne infections. And nine of ten had evidence of autoimmune encephalitis.
Autoimmune encephalitis is the medical term for ‘Brain on Fire’: inflammation in the brain that can result in serious mood, behavioral and cognitive disorders.
Susan Swedo at the National Institute of Mental Health first described this condition in children who developed neuropsychiatric symptoms shortly after a strep infection, and she termed it Pediatric Autoimmune Neuropsychiatric Disorder Associated with Streptococcal Infections—PANDAS. (3-4)
Not long afterwards it became clear that multiple microbes other than Streptococcus can trigger autoimmune encephalitis, and the name was broadened to Pediatric Acute-Onset Neuropsychiatric Disorder—PANS.
The microbes that thus far have been shown to trigger PANS include several viruses including Epstein-Barr, the common cold, influenza, and chicken pox as well as Bartonella, Mycoplasma and mold. (5-7) There was a recent report out of Italy describing two boys in whom SARS-CoV-2, the virus that causes Covid-19, triggered PANS. (8) It is likely, but not clear at this time, that Borrelia burgdorferi, the Lyme pathogen, also triggers PANS.
In 2013, the PANS collaborative consortium published criteria for the diagnosis of PANS. (9) These include the sudden onset of obsessive-compulsive disorder (OCD) or severely restricted food intake, without a known medical disorder that would account for these symptoms. In addition, the case definition requires two of the following seven criteria to make the diagnosis:
It is important to have clear diagnostic criteria so that researchers studying this condition are always studying the same population of subjects, but not all kids with autoimmune encephalitis will fulfill these criteria. In particular, most of my patients do not have an acute—i.e, sudden—onset of their symptoms; the onset may be stuttering or slow.
According to the National Institutes of Mental Health, nearly one-third of all adolescents ages 13 to 18 will experience an anxiety disorder, and 8% of those will become severely impaired. (10) The NIMH also reported that the prevalence of major depressive disorder in adolescents in 2017 was 13.3%, with nearly three-quarters of those becoming severely impaired. (11) Suicide has replaced homicide as the second most common cause of death for teenagers ages 10 to 19 in the United States. (12)
In other words, we have an epidemic of mental illness in adolescents.
Our investigation was small. Ten adolescents picked at random with mental illness severe enough that they required institutionalization—nine of ten had evidence of tick-borne infections and nine of ten had evidence of autoimmune encephalitis.
Clearly there is a need for more investigation, but I suspect that many of the teens afflicted with mental illness in the U.S. are suffering from brains on fire. Their illness may present as emotional, but the cause may be organic. In the next installment I will discuss the diagnosis and treatment of PANS.

Lyme disease can be notoriously difficult to diagnose. This Giving Tuesday, Project Lyme and the Bay Area Lyme Foundation are raising funds to support Sapient in bringing an accurate tool to diagnose chronic Lyme disease to the market.

A recent Washington Post article asked a doctor, "A tick bit me. What do I do now?". The responses included false or potentially misleading information, so we decided to address the issues in order to help patients avoid confusion.

There are 15 different tick-borne diseases, including the topic of this article, Bartonella. The ability of ticks to harbor and transmit Bartonella has been heartily debated for years because of the lack of direct, conclusive evidence. This blog works to dispel this debate by sharing existing research in order to outline why both patients and medical care providers should consider Bartonella as part of the differential diagnosis.
