Proactive Health Management Makes a Difference

Individuals with Down syndrome have a higher likelihood of certain health conditions compared to the general population. This doesn't mean these conditions are inevitable — but it does mean that regular, proactive health monitoring is an important part of caring for someone with Trisomy 21. The good news is that with appropriate monitoring and early treatment, most of these conditions are very manageable.

This guide is based on general health guidelines from Down syndrome medical advisory groups. Always work with your healthcare providers to create a personalized health plan.

Newborn and Early Infancy Screenings

The newborn period involves several important checks:

  • Cardiac evaluation: Around 40–50% of babies with Down syndrome are born with a congenital heart defect. An echocardiogram (heart ultrasound) is recommended for all newborns with Down syndrome, even if no murmur is heard.
  • Hearing screening: Newborn hearing screens should be completed before discharge. Hearing loss is common and can be conductive, sensorineural, or both.
  • Thyroid function: Congenital hypothyroidism screening is part of standard newborn screening, but ongoing thyroid monitoring is important throughout life.
  • Vision assessment: A referral to a pediatric ophthalmologist is recommended in the first year.
  • Feeding support: Many newborns benefit from a lactation consultant and/or feeding therapist due to low muscle tone affecting suck-swallow coordination.

Infancy Through Preschool (Ages 1–5)

  • Hearing checks: Audiological evaluations every 6–12 months. Ear infections and middle ear fluid (otitis media with effusion) are very common and can impact hearing and language development.
  • Vision: Annual ophthalmology visits. Watch for strabismus (crossed eyes), nystagmus, and refractive errors.
  • Thyroid: Annual thyroid-stimulating hormone (TSH) testing.
  • Atlantoaxial instability screening: The cervical spine (neck vertebrae) can be less stable in Down syndrome. Discuss X-ray screening with your doctor before high-impact sports or surgeries requiring neck positioning.
  • Dental: First dental visit by age 1 or when first teeth appear.

School Age (Ages 6–12)

  • Continue annual hearing and vision checks
  • Annual TSH (thyroid) testing
  • Monitor for sleep apnea — obstructive sleep apnea is very common in Down syndrome due to airway anatomy. A sleep study (polysomnography) is often recommended even without obvious symptoms.
  • Dental care and orthodontic evaluation
  • Screen for celiac disease — more prevalent in individuals with Down syndrome than in the general population
  • Watch for signs of autism spectrum disorder or behavioral/mental health challenges, which are more common

Adolescence (Ages 13–21)

  • Continued thyroid monitoring
  • Gynecological care for females; fertility counseling as appropriate
  • Mental health screening — depression and anxiety rates are higher in teens with Down syndrome
  • Ongoing sleep apnea monitoring
  • Transition planning for adult healthcare providers

Adulthood

Adults with Down syndrome live longer, healthier lives than ever before — life expectancy has increased dramatically over recent decades. Key adult health considerations include:

  • Alzheimer's disease: Adults with Down syndrome have a higher lifetime risk due to the location of the amyloid precursor protein gene on chromosome 21. Regular cognitive screenings from around age 40 are recommended.
  • Ongoing thyroid, hearing, vision, and dental monitoring
  • Heart health monitoring for those with repaired congenital heart defects
  • Mental health and wellbeing support

Finding a Down Syndrome Clinic

Many children's hospitals and academic medical centers have dedicated Down syndrome specialty clinics staffed by teams familiar with all these health considerations. These clinics can help coordinate care and ensure nothing falls through the cracks. Ask your pediatrician for a referral, or search through the National Down Syndrome Society (NDSS) or your regional Down syndrome association for clinic listings.

Knowledge is power. Understanding what to monitor means you can partner with your medical team proactively — and focus the rest of your energy on celebrating your child's amazing life.
