Ask a parent of a young adult with cerebral palsy what happens after the pediatric specialist signs off, and you will hear a version of the same story. The phone calls to adult neurologists. The waitlists. The provider who admits, politely, that CP was barely covered in training. The slow realization that the coordinated care that defined childhood is not waiting on the other side of the birthday.
This is not a rare scenario. It is the new reality for a population that grew past the system built to serve it.
Adults With CP Now Outnumber Children With CP
For most of modern medical history, cerebral palsy was treated as a pediatric condition. Specialists trained around children, and insurance and research pathways followed that same logic.
Then the population aged. Thanks to improvements in life expectancy for people with cerebral palsy, adults with CP now outnumber children with the condition in the United States. The medical infrastructure did not age with them.

Medicine solved part of the problem. It is still working on the rest.
Why Adult CP Specialists Are Nearly Impossible to Find
Workforce reporting from the American Academy for Cerebral Palsy and Developmental Medicine points to a structural problem: there is no formal board-certified pathway specifically for adult CP care. Pediatric specialists often cannot continue treating patients past a certain age due to hospital policies and insurance limitations. Adult neurologists, physiatrists, and primary care providers rarely receive dedicated CP training during residency.
The result is a workforce gap that widens every year. A five-year-old with CP can typically access a coordinated team of specialists. A twenty-five-year-old with the same condition often cannot find one.
HCBS Waiver Waitlists Now Stretch for Years in Many States
The next layer of the cliff sits inside Medicaid. Adults with developmental disabilities frequently rely on Home and Community-Based Services waivers to stay out of institutional settings and live in their communities. Kaiser Family Foundation data on HCBS waiver waitlists shows that on average, people with intellectual or developmental disabilities wait 37 months for services. And people living in states that do not screen for eligibility often wait longer (49 months on average).Â
Dual-eligible beneficiaries with developmental disabilities add context, showing how coverage patterns shift once a person ages out of pediatric programs as documented in the Got Transition National Report on Aging Out. The report shows that while 58% of youth with disabilities ages 12-18 are publicly insured, that number drops to 43% for young adults ages 19-25.
Even With a Waiver, There May Be No One to Provide Care
Another shortage waits behind the waiver. Bureau of Labor Statistics data on direct support professionals, the workers who provide in-home and community-based care, shows low wages alongside high turnover and an aging workforce. Projected shortages keep climbing.
This creates a fractured cycle: families fight to secure a waiver and the funding it provides, only to find that the system stalls because the essential direct support worker simply isn’t there.
What Families Can Do Right Now
Until policy moves, families are bridging the gap themselves. That means starting transition planning years before pediatric care ends, identifying adult providers willing to learn the condition, applying for waivers as early as eligibility allows, and getting legal and financial planning in place before a crisis forces it.
Organizations like the Cerebral Palsy Center have become navigation tools for families working through adult care, transition planning, and the patchwork of services that vary widely by state.
What This Means for the Broader Healthcare System
The adult CP care gap is not isolated. Survival rates have improved across many conditions once considered exclusively pediatric, including sickle cell disease, congenital heart conditions, certain childhood cancers, and rare genetic disorders. Each of those produces an adult population the system was not designed around.
Cerebral palsy is simply further along the curve. The question for policymakers and insurers is whether to keep absorbing the cost of an undersized adult care system, or to start building for the population that already exists.
