Dr. Daniel Shtraykher, DO

Dr. Daniel Shtraykher is a board-certified pediatrician in Brooklyn who specializes in children’s neuro-immune and complex chronic conditions. He began by treating PANDAS/PANS, and his practice has grown to include mold illness (CIRS), chronic Lyme and coinfections, mast cell activation syndrome (MCAS), POTS/dysautonomia, ADHD, and folate-transport problems in autism (including folinic acid/leucovorin therapy).

Drawing on genetics, immune biology, and environmental medicine, Dr. Shtraykher recognizes that these diagnoses often overlap—shared pathways (inflammation, autoimmunity, mitochondrial stress, connective-tissue traits, and detox genetics) can blur boundaries. Instead of slicing a child into separate labels, he integrates findings and treats the root network: infections and biotoxins, immune dysregulation, mast-cell reactivity, autonomic imbalance, nutrient/folate transport, and the home environment.

His care is evidence-informed and practical: clear history, targeted testing when useful, and therapeutic trials when time or cost matters. Treatments may include antimicrobial strategies, anti-inflammatory and mast-cell stabilization, autonomic support for POTS, binders/detox for CIRS, and folinic acid for children with suspected cerebral folate deficiency—especially those with FRAA/FRAT positivity—often alongside school and behavioral supports.

Dr. Shtraykher accepts Medicaid and most major insurance, making specialized neuro-immune care accessible to families. His goal is simple: see the big picture, address what’s driving a child’s brain-body symptoms, and help kids regain function—whether the trigger is strep, mold, Lyme, MCAS, POTS, ADHD-related vulnerabilities, or folate transport.
