Down Syndrome
Clinical care in Down syndrome requires structured surveillance for congenital heart disease and evolving multisystem complications, plus a deliberate adult-life transition plan that recognizes the high risk of Alzheimer disease and changing care needs.
New diagnosis
Prioritize cardiac characterization and organized health supervision
The first management decision is whether an unrecognized congenital lesion or associated condition requires immediate specialty-directed care.
Arrange echocardiography at birth after confirmation of Down syndrome and route abnormal findings to pediatric cardiology for lesion-specific follow-up. Congenital heart disease is reported in approximately 35% to 50% of individuals with trisomy 21; CDC reports heart defects in 50% to 65% of affected newborns, with some lesions requiring surgery and others potentially improving with growth.AHA Journals+1AHA JournalsTrisomy 21 and Congenital Heart Disease: Impact on ...CDCLiving with Down Syndrome | Birth Defects | CDC
Place the patient into a longitudinal Down syndrome health-supervision pathway rather than episodic problem-based follow-up. American Academy of Pediatrics guidance is intended to direct care after diagnosis is confirmed, and an integrated electronic health-record approach can improve adherence to surveillance recommendations.publications aap+1publications aapHealth Supervision for Children With Down Syndromepublications aapUse of Electronic Health Record Integration for Down ...
At each transition of care, confirm that cardiac findings, audiology and ophthalmology results, thyroid history, gastrointestinal symptoms, neurologic events, sleep or breathing concerns, and cervical-spine symptoms have been explicitly reviewed. Hearing and vision problems, gastrointestinal conditions, epilepsy, hypothyroidism, and atlantoaxial instability are recurring clinically relevant associations.ScienceDirect+2ScienceDirectOrthopaedic Management in Down SyndromeScienceDirectThe disability-training needs of healthcare professionalspublications aapDOWN SYNDROME: MANAGING THE CHILD AND FAMILY

Clinical reassessment
Use new symptoms to identify treatable associated conditions
New functional or behavioral change should trigger a targeted medical review rather than attribution to baseline disability.
When a child has developmental regression, reduced participation, gait change, pain behavior, altered sleep, new feeding difficulty, or unexplained behavioral change, reassess for hearing loss, visual impairment, hypothyroidism, gastrointestinal disease, epilepsy, and cervical-spine pathology. These conditions are recognized co-occurring problems in Down syndrome and can alter function independently of cognitive baseline.ScienceDirect+3ScienceDirectOrthopaedic Management in Down SyndromeScienceDirectThe disability-training needs of healthcare professionalsWileyCo‐Occurring Medical Conditions in Over 2300 Children ...publications aapDOWN SYNDROME: MANAGING THE CHILD AND FAMILY
Use focused history and examination to determine the next referral. Neck symptoms or neurologic findings warrant careful assessment for atlantoaxial instability; orthopedic clinicians may also identify systemic contributors such as hypothyroidism while evaluating musculoskeletal complaints.ScienceDirect+1ScienceDirectOrthopaedic Management in Down Syndromepublications aapDOWN SYNDROME: MANAGING THE CHILD AND FAMILY
Escalate persistent gastrointestinal symptoms toward evaluation for celiac disease rather than treating nonspecific symptoms indefinitely. AAP-linked Down syndrome management materials specifically identify symptoms potentially related to celiac disease as a trigger for clinical assessment.publications aappublications aapDOWN SYNDROME: MANAGING THE CHILD AND FAMILY
Treat sensory concerns as medical contributors to communication, learning, and apparent behavioral decline. Because hearing and vision problems are prevalent in this population, a change in function should prompt review of the most recent formal assessments and completion of indicated specialty evaluation.ScienceDirect+1ScienceDirectThe disability-training needs of healthcare professionalspublications aapDOWN SYNDROME: MANAGING THE CHILD AND FAMILY
For a new seizure-like event, obtain a neurologic assessment rather than assuming a behavioral episode; epilepsy is reported among common health problems in Down syndrome.ScienceDirectScienceDirectThe disability-training needs of healthcare professionals
For suspected hypothyroidism, obtain thyroid testing and interpret symptoms against baseline function; hypothyroidism may be discovered during orthopedic evaluation.ScienceDirectScienceDirectOrthopaedic Management in Down Syndrome
For concerning neck or neurologic symptoms, avoid clearance based solely on absence of prior symptoms and pursue cervical-spine-focused evaluation.publications aappublications aapDOWN SYNDROME: MANAGING THE CHILD AND FAMILY
Procedural care
Plan sedation and surgery as higher-variability care
Preprocedural planning should address comorbid organ disease and variable perioperative physiology.
Before sedation, anesthesia, or major surgery, obtain a current cardiac history and review respiratory status, prior anesthetic records, medications, bleeding history, and anticipated postoperative support needs. Down syndrome has been associated with unpredictable and potentially serious perioperative respiratory, coagulation, drug-metabolism, and delayed-healing complications.NatureNatureDown Syndrome Reduces the Sedative Effect of ...
Do not assume that a standard sedative response applies. A clinical study reported reduced sedative effect in patients with Down syndrome, while emphasizing variable and serious perioperative complications; anesthesia dosing and monitoring should therefore be individualized by the procedural and anesthesia teams.NatureNatureDown Syndrome Reduces the Sedative Effect of ...
For procedures requiring neck positioning or airway manipulation, communicate any cervical-spine symptoms, prior atlantoaxial concerns, and neurologic findings to anesthesia and procedural teams. Cervical-spine assessment is particularly relevant when symptoms suggest atlantoaxial instability.ScienceDirect+1ScienceDirectOrthopaedic Management in Down Syndromepublications aapDOWN SYNDROME: MANAGING THE CHILD AND FAMILY

Adult medicine
Establish cognitive baselines and investigate decline for Alzheimer disease
Longer survival makes adult surveillance, function tracking, and dementia evaluation central components of care.
Establish a documented adult baseline for cognition, adaptive function, behavior, mobility, communication, and caregiver-observed daily performance. Adults with Down syndrome have increased Alzheimer disease risk because chromosome 21 triplication includes genes implicated in Alzheimer disease biology.Wiley+1WileyIncreased choroidal thickness in adults with Down syndromeWileyExploratory analysis of the proteomic profile in plasma in ...
A progressive decline from baseline should prompt evaluation for Alzheimer disease while also revisiting reversible contributors that are common in Down syndrome, including sensory impairment, hypothyroidism, epilepsy, gastrointestinal disease, and cervical-spine pathology when clinically suggested.ScienceDirect+2ScienceDirectOrthopaedic Management in Down SyndromeScienceDirectThe disability-training needs of healthcare professionalspublications aapDOWN SYNDROME: MANAGING THE CHILD AND FAMILY
Counsel families that Alzheimer disease pathology becomes increasingly relevant with age: reports note that most individuals with Down syndrome develop Alzheimer disease pathology by age 40, and population-level Alzheimer reporting identifies Down syndrome as a high-risk group for symptomatic dementia.Wiley+2Wiley2024 Alzheimer's disease facts and figuresWileyAlzheimer's disease diagnostic progression is associated with ...WileyCalcineurin inhibition may prevent Alzheimer disease in ... This risk supports proactive functional surveillance rather than waiting for advanced dependence.
Integrate cognitive assessment with medical transition planning. Life expectancy for people with Down syndrome has increased substantially over recent decades, expanding the need for adult primary care, congenital cardiology continuity when applicable, and longitudinal caregiver support.Wiley+2Wiley2026 Alzheimer's disease facts and figuresCDCLiving with Down Syndrome | Birth Defects | CDCWiley2025 Alzheimer's disease facts and figures
Record caregiver examples of change in daily tasks, communication, mobility, sleep, and behavior at each adult follow-up to distinguish chronic baseline limitations from decline.
When decline is identified, first review medications, interval seizures, sensory testing, thyroid status, and new focal neurologic or gait findings before assigning a neurodegenerative explanation.ScienceDirect+2ScienceDirectOrthopaedic Management in Down SyndromeScienceDirectThe disability-training needs of healthcare professionalspublications aapDOWN SYNDROME: MANAGING THE CHILD AND FAMILY
