7-year-old girl with Lyme disease presenting as attention deficit disorder
Children are at the greatest risk for developing Lyme disease, with the highest rates of infection occurring in those ages 5 to 9. And out of the more than 300,000 people diagnosed annually in the U.S. with Lyme disease, 25% are children, according to the Centers for Disease Control and Prevention (CDC). This is particularly alarming given that the disease can be difficult to identify in younger patients with symptoms often overlooked or attributed to other medical conditions.

Susan, a 7-year-old girl who had difficulty focusing in school, was initially diagnosed by a neurologist with probable attention deficit disorder. But she exhibited numerous other symptoms consistent with Lyme disease, as described by Fallon from the Department of Psychiatry, Columbia University Medical Center and the Lyme Disease Research Program, New York.
These symptoms included:
- Poor coordination
- Joint pain
- Word-finding difficulties
- Light and sound sensitivity
The young girl’s medical workup revealed a positive Lyme ELISA. After starting antibiotic treatment, her attention deficit disorder resolved and her school grades returned to normal. “Her course over the subsequent 2 years appeared to be antibiotic-dependent, such that she would do well as long as she stayed on antibiotics and relapse when taken off,” writes Fallon and colleagues in an article entitled, “The underdiagnosis of neuropsychiatric Lyme disease in children and adults.”
From age 9 to 12, she remained symptom-free without the need for antibiotics and maintained A to A+ grades. Unfortunately, at age 12 symptoms appeared to return. She developed knee pain, frequent headaches, and poor concentration.
Again, serologic tests were positive by ELISA, IgG and IgM western blots. She rapidly improved with a two-month course of oral cefuroxime. Her symptoms recurred two months after the end of treatment.
Her teacher reported numerous problems, including:
- “trouble with consistency in day-to-day work; careless; head in the clouds; scattered and sloppy work; assignments are late, forgotten, or lost; difficult time following directions; more forgetful and disorganized.”
- “Her parents noted that Susan would go to school with homework in her bag but once there have no idea where it was or whether she had done it.”
- “Emotionally, she had become frustrated, overwhelmed, tearful, aggressive, and fearful with new onset phobias and nightmares.”
- “Physically, she had knee pain with mild swelling, paresthesias, headaches, moderate fatigue, insomnia, and trouble focusing.”
Her neurocognitive testing revealed 6 of 9 inattention areas consistent with attention deficit hyperactivity disorder (ADHD), no depression or suicidal feeling, a verbal IQ of 132, “but significant deficits in visual motor planning, speed of processing, visual scanning, attention, visual memory, and learning,” according to Fallon.
Subsequently, Susan was diagnosed with a persistent encephalopathy secondary to Lyme disease and, after several months of oral antibiotics, returned to normal without ADHD.

She’s “lucky” that her Lyme tests showed positive and that she received treatment. So many do not.
Hope this informaiton gets to Special Education Departments in local school systems.
Which antibiotic ultimately worked for Susan and how long did she have to take the antibiotics.
Same questions. We are in the same exact situation. I am inquiring about retesting this summer and going back on abx instead of the adhd medications that made Lyme rage way worse! We need major help. My son has had Lyme for 4 years now.
I have children with Lyme disease and rage in my practice.
