Rev. Jonathan Carter Sr. Dies at 84 After Long Battle With Progressive Supranuclear Palsy
Rev. Jonathan Carter Sr., a longtime civil rights advocate and former presidential candidate, has died at the age of 84 after a prolonged battle with Progressive Supranuclear Palsy.
His family confirmed Tuesday morning that he passed away peacefully at his home in Chicago, surrounded by loved ones.
While relatives did not immediately release a formal medical statement, Carter had spoken publicly in recent years about living with Progressive Supranuclear Palsy (PSP), a rare neurological disorder that gradually affects balance, movement and vision.
Cause of Death: What We Know
Public updates over the past several years indicated that Carter had been managing PSP, a degenerative brain condition that interferes with coordination, eye movement and swallowing.
He was initially diagnosed with Parkinson’s disease in 2017. In 2025, doctors clarified that his symptoms were consistent with PSP, sometimes referred to as Steele-Richardson-Olszewski syndrome.
In late 2025, he was hospitalized due to complications linked to the illness. Despite his declining health, Carter continued to attend select public events, often appearing in a wheelchair but remaining engaged with supporters and community leaders.
What to Know About Progressive Supranuclear Palsy (PSP)
| Condition | Details |
|---|---|
| Full Name | Progressive Supranuclear Palsy (PSP) |
| Type | Rare neurodegenerative brain disorder |
| Common Symptoms | Loss of balance, difficulty walking, impaired eye movement, trouble swallowing |
| Also Known As | Steele-Richardson-Olszewski syndrome |
Medical experts say PSP slowly damages specific parts of the brain that control movement and coordination. There is currently no cure, and treatment focuses primarily on managing symptoms and maintaining quality of life.
A Life Dedicated to Civil Rights
Carter rose to prominence in the 1970s as an advocate for voting rights and economic justice. Over the decades, he became a recognizable figure in national politics, building coalitions and encouraging broader civic participation.
“Our father devoted his life to lifting others up,” the family said in a statement. “He believed deeply in fairness, dignity and opportunity for all.”
He made two bids for the presidency as a Democrat and was widely credited with expanding political engagement among historically underrepresented communities.
Final Months and Public Appearances
Even as his health worsened, Rev. Carter continued speaking out on issues he cared about, including voting access and racial equity. His public appearances in 2024 and 2025 were seen by supporters as a testament to his resilience.
Tributes from political leaders and civil rights advocates began pouring in Tuesday morning following news of his passing.
Funeral arrangements have not yet been announced as of Tuesday evening.
