SSI is needs-based; SSDI depends on insured work history, with special rules potentially relevant to disabled adult children. Use SSA and qualified benefits counseling for individual eligibility.
What this means in real life
SSI and SSDI are different. Supplemental Security Income is needs-based and considers disability plus income/resources; children are evaluated under child rules and parental income may be deemed. Social Security Disability Insurance is based on an insured worker’s record. An adult whose disability began before age 22 may sometimes qualify for Disabled Adult Child benefits on a parent’s Social Security record when other requirements are met.
A DMD diagnosis is important, but applications should document function: walking, transfers, arm use, breathing, fatigue, personal care, school/work and medical treatment. Keep records current and answer forms based on what happens on difficult and typical days—not the best isolated performance.
Cash benefits, Medicare/Medicaid links and work incentives differ. Use official SSA information and qualified benefits counseling, particularly around age 18, parental retirement/disability, work or marriage.
