Could Lyme Disease Cause ADHD Symptoms in Children?
Lyme disease ADHD symptoms children may mimic attention deficit disorder, making diagnosis challenging.
After 37 years treating Lyme disease, I have seen children diagnosed with ADHD whose symptoms improved with antibiotic treatment. This case highlights why attention problems in children may warrant evaluation for tick-borne infections.
When School Struggles Signal Infection
A 7-year-old girl with difficulty focusing in school was initially diagnosed with probable attention deficit disorder. However, she exhibited additional symptoms consistent with Lyme disease, as described by Fallon.
Her symptoms included:
- Lethargy
- Irritability
- Forgetfulness
- Headaches
- Poor coordination
- Joint pain
- Word-finding difficulties
- Light and sound sensitivity
Response to Treatment
Lyme testing was positive by ELISA, and antibiotic treatment was initiated.
Her attention difficulties resolved, and her school performance returned to normal.
Over the next two years, her symptoms appeared antibiotic-dependent, improving on treatment and recurring when treatment stopped. From ages 9 to 12, she remained symptom-free without antibiotics.
Relapse and Ongoing Symptoms
At age 12, symptoms returned, including knee pain, headaches, and poor concentration.
Serologic testing again confirmed Lyme disease. She improved with oral cefuroxime but relapsed after treatment ended.
Teachers reported worsening attention, organization, and emotional regulation, along with physical symptoms including fatigue, insomnia, and pain.
Neurocognitive Findings
Testing showed deficits in attention, processing speed, visual memory, and learning.
Although she met criteria for ADHD, the broader clinical picture suggested Lyme-related encephalopathy.
After extended antibiotic treatment, her symptoms resolved and she no longer met criteria for ADHD.
Why Lyme Disease Can Mimic ADHD
Lyme disease ADHD symptoms children may result from neuroinflammation and cognitive dysfunction.
Symptoms such as poor concentration, memory problems, and emotional changes can overlap with ADHD.

Clinical Perspective
Lyme disease ADHD symptoms children should be considered when attention problems are accompanied by physical symptoms or sudden onset.
Clinical context, including exposure risk and symptom pattern, is essential for accurate diagnosis.
Clinical Takeaway
Lyme disease ADHD symptoms children may mimic attention disorders but can improve with appropriate treatment.
Evaluation for Lyme disease may be appropriate in children with atypical or treatment-resistant ADHD symptoms.
Frequently Asked Questions
Can Lyme disease cause ADHD-like symptoms in children?
Yes. Lyme disease can cause attention problems, poor concentration, and organizational difficulties that resemble ADHD.
How can doctors tell the difference?
Clues include physical symptoms, sudden onset, and improvement with antibiotics rather than ADHD medications.
Should children with ADHD be tested for Lyme disease?
Testing may be considered when symptoms are atypical or occur in endemic areas.

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.
She’s “lucky” that her Lyme tests showed positive and that she received treatment. So many do not.
