What is Pediatric Lyme

Pediatric Lyme is not simply adult Lyme in a smaller body. When tick-borne disease affects a child, it intersects with growth, neurological development, emotional regulation, and identity formation. The result is often a very different clinical and lived experience.

Children’s immune systems are still developing and learning, and infection can disrupt that process. Pediatric Lyme can be subtle and inconsistent as no bite is recalled, no rash, migrating symptoms or may test negative.

  • Immune responses may be stronger, exaggerated, or inconsistent

  • Antibody testing can be less predictable in early stages

  • Inflammation may affect the brain more prominently

  • Symptoms can fluctuate dramatically

  • Children often present very differently. Symptoms may include:

    • Sudden anxiety or separation anxiety

    • Irritability or rage episodes

    • Mood swings

    • OCD-like behaviors

    • Sleep disturbance or night terrors

    • School refusal

    • Cognitive regression

    • Headaches

    • Gastrointestinal issues

    • Shin or foot pain

    • Fatigue

    Children may not say, “My joints hurt.” They may say:

    • “My legs don’t work.”

    • “I’m too tired to play.”

    • “My brain feels weird.”

  • Behavioral changes in pediatric Lyme are often neurological inflammation in disguise. These symptoms may be misinterpreted as primary psychiatric conditions.

    Common patterns include:

    • Sudden onset anxiety/OCD behaviors

    • Dramatic personality changes

    • Emotional volatility that feels out of character

    • Decline in executive functioning

  • Biological, Cognitive and Neurological symptoms can significantly impact learning.

    Children may experience:

    • Growth, puberty and hormones

    • Social and self esteem

    • Difficulty keeping up with schoolwork

    • Increased time needed for assignments

    • Problems with attention or focus

    • Word-finding difficulties

    • Increased anxiety around school or school refusal

    • Behavioral challenges

  • Consider speaking with a healthcare provider if:

    • Your child has symptoms following a known or possible tick bite

    • Symptoms persist without clear explanation

    • Your child’s functioning or behavior has noticeably changed

    • Fatigue, pain, or cognitive/behavioral changes interfere with daily life

    Trust your instincts. You know your child best. If something feels off, seeking answers is a reasonable and proactive step.
