Simplify Your Home Care Operations
CareCade helps DDA and HCBS providers manage scheduling, EVV, and billing in one platform.
Something unprecedented is happening in disability services. Thanks to advances in medical care, community living, and public health, people with intellectual and developmental disabilities (IDD) are living longer than ever before.
In the 1930s, the average life expectancy for a person with Down syndrome was 9 years. Today, it's over 60 years, according to the National Down Syndrome Society. For people with other developmental disabilities, similar—if less dramatic—increases have occurred.
This is a triumph. But it's also creating a care crisis that the home care system isn't prepared for.
The Numbers
A Growing Population
According to the Administration for Community Living and research published in the American Journal on Intellectual and Developmental Disabilities:
- An estimated 1.3 million Americans over age 60 have an intellectual or developmental disability
- That number is projected to double by 2035 as the Baby Boom generation of people with IDD ages
- 641,000 individuals with IDD are currently cared for by family members over age 60
- An estimated 25% of family caregivers of adults with IDD are themselves over age 75
The Dual Aging Crisis
The most acute challenge isn't just that people with IDD are aging—it's that their caregivers are aging too.
Consider a common scenario in Washington State: A mother, now 78, has cared for her son with autism and intellectual disability his entire life. He's now 52. She's his primary caregiver, his advocate, his link to services. When she can no longer provide care—through illness, incapacity, or death—what happens?
This scenario plays out thousands of times across the country every year. The Rehabilitation Research and Training Center on Aging with Developmental Disabilities estimates:
- 75% of adults with IDD live with family members
- The average age of family caregivers is rising by 1 year annually
- Over 700,000 family caregiving situations will reach crisis point in the next decade as caregivers become unable to continue
The Clinical Complexity
Aging with a developmental disability is clinically distinct from typical aging. People with IDD face:
Earlier Onset of Age-Related Conditions
- Dementia: Adults with Down syndrome face a 90% lifetime risk of Alzheimer's disease, with onset typically in their 40s and 50s—decades earlier than the general population
- Sensory decline: Vision and hearing loss begin earlier and progress faster
- Mobility limitations: Orthopedic conditions and reduced physical activity accelerate physical decline
- Chronic disease: Higher rates of diabetes, heart disease, and obesity
Diagnostic Challenges
Many age-related conditions are harder to diagnose in people with IDD:
- Cognitive decline is difficult to distinguish from baseline intellectual disability
- Pain may be expressed through behavior changes rather than verbal complaints
- Standard screening tools aren't validated for people with IDD
- Healthcare providers often lack training in geriatric care for people with disabilities
Medication Complexity
As medical conditions multiply, so do medications:
- Polypharmacy (5+ medications) is common in aging adults with IDD
- Drug interactions are harder to monitor
- Side effects may be misinterpreted as behavioral issues
- Many individuals cannot self-report side effects
The Service Gap
The home care system was designed around two separate populations: people with disabilities (typically younger) and seniors (typically without developmental disabilities). The growing population of older adults with IDD falls between these two systems.
What's Missing
| Need | Disability System | Aging System | Gap |
|---|---|---|---|
| Dementia care | Limited expertise | Designed for it | IDD-specific dementia protocols |
| Day programs | Available but age-inappropriate | Limited for IDD | Age-appropriate programming |
| Health monitoring | Basic | Advanced | Adapted monitoring for IDD |
| End-of-life planning | Rarely addressed | Standard | Accessible planning tools |
| Housing | Group homes, supported living | Senior living | Combined options |
Workforce Challenges
Caring for aging adults with IDD requires skills from both disability services and geriatric care:
- Understanding of developmental disabilities AND age-related conditions
- Training in dementia care adapted for people with IDD
- Knowledge of both DDA waiver systems and aging services
- Patience and flexibility to manage increasing complexity
Most direct support professionals (DSPs) are trained in one system or the other—rarely both.
What Families Are Facing
The "What Happens When I'm Gone?" Question
For aging parents of adults with IDD, this question drives everything. Planning must address:
- Residential transition: Where will their child live? Who will manage the transition?
- Guardianship succession: Who assumes legal responsibility?
- Financial planning: Are ABLE accounts, special needs trusts, and benefits in order?
- Medical advocacy: Who will attend appointments, manage medications, communicate with providers?
- Social continuity: Who will maintain relationships, routines, and community connections?
The Emotional Weight
Many aging parents have spent 50+ years as primary caregivers. They've fought for services, navigated bureaucracies, and built entire support systems around their child. Letting go—or being forced to let go—is both practically and emotionally devastating.
Research from the National Alliance for Caregiving shows that aging caregivers of adults with IDD experience:
- Higher rates of depression and anxiety than other caregiver populations
- Physical health deterioration from decades of caregiving
- Social isolation as their peer networks shrink
- Financial stress from lifetime caregiving costs
What Washington State Is Doing
Washington has taken some steps to address the aging IDD population, but significant gaps remain.
Existing Supports
- DDA Waiver Services: Washington's waiver system provides home and community-based services, but wait lists persist
- Aging and Long-Term Support Administration (ALTSA): Provides services for seniors, but limited IDD expertise
- Roads to Community Living: Helps transition people from institutional to community settings
- Individual and Family Services (IFS) waiver: Supports families providing care at home
What's Needed
- Cross-system coordination: Better collaboration between DDA and ALTSA
- Dual-trained workforce: DSPs who understand both aging and developmental disabilities
- Transition planning requirements: Mandatory planning for aging caregiver situations before crisis
- Specialized housing: Options designed for aging adults with IDD
- Respite expansion: More accessible respite to sustain aging caregivers longer
What Home Care Agencies Can Do
Identify At-Risk Situations
Proactive agencies monitor their client base for emerging aging challenges:
- Which clients have primary caregivers over 65? Over 75?
- Which clients are showing signs of age-related decline?
- Which families lack succession plans for caregiving?
- Which clients need updated assessments reflecting changing needs?
Build Aging-Specific Capabilities
Invest in staff skills that address the aging IDD population:
- Dementia care training adapted for people with developmental disabilities
- Medication management monitoring and reporting
- Fall prevention and mobility support
- Health monitoring and vital sign tracking
- End-of-life care and comfort measures
Support Family Transitions
Help families plan and execute transitions before they become emergencies:
- Connect aging caregivers with respite services
- Facilitate introductions to new caregivers gradually
- Document care routines, preferences, and medical information
- Coordinate with case managers on transition planning
- Provide emotional support during the transition process

Looking Ahead
The aging IDD population will only grow. The families caring for them will only get older. The service system will either adapt or fail them.
For home care agencies, this is both a challenge and an opportunity. The agencies that develop expertise in serving aging adults with developmental disabilities will fill a critical gap—and build a sustainable service niche in the process.
For families, planning now—while caregivers are still able to participate—is essential. Don't wait for a crisis to answer the question every aging parent asks: "What happens when I'm gone?"
The answer should be: "We've planned for this. The care continues."
