Most people don’t expect a presidential candidate to casually mention a parasite living in their brain, but Robert F. Kennedy Jr. did just that in a 2012 deposition, revealing a diagnosis that would later become front-page news. This article traces how a misdiagnosis of brain cancer turned out to be a tapeworm infection, and what it means for understanding a man whose life has been shaped by both a famous political family and an extraordinary personal health story.

What is the condition that Robert F. Kennedy Jr. has?
Does RFK actually have a brainworm?
- RFK Jr. was diagnosed with neurocysticercosis after a CT scan revealed a dark spot initially thought to be brain cancer (STAT News)
- The infection is caused by the larval stage of the pork tapeworm Taenia solium (CDC)
- He reported memory loss and mental fogginess before diagnosis and later said he recovered without aftereffects (STAT News)
The evidence is clear: RFK Jr. did have a parasitic worm living in his brain. The condition, known as neurocysticercosis, occurs when tapeworm larvae form cysts in the central nervous system (WHO).
For Kennedy, the misdiagnosis nearly led to unnecessary brain surgery at Duke University Medical Center before a doctor at New York Presbyterian corrected it (Washington Post via UC Riverside). The near-miss underscores how easily parasitic infections are mistaken for malignancies.
How did RFK Jr. get the brain worm?
- Neurocysticercosis is contracted by ingesting eggs of Taenia solium, typically through contaminated food or water (CDC)
- The eggs hatch in the intestines and the larvae migrate to tissues including the brain (WHO)
- Poor hygiene or undercooked pork are common transmission routes (NIH)
The implication: Kennedy almost certainly acquired the infection through contaminated food, likely during travel or consumption of undercooked pork—a scenario familiar to infectious disease specialists.
How are RFK Jr. and JFK related?
Who is RFK Jr.’s father?
- He is the third of eleven children born to Robert F. Kennedy and Ethel Kennedy (Wikipedia)
- His father, Robert F. Kennedy, served as U.S. Attorney General and was assassinated in 1968 (Wikipedia – RFK Sr.)
The pattern: RFK Jr. grew up immersed in a political dynasty that has shaped American public life for decades.
What is the Kennedy political dynasty?
The Kennedy family is one of the most prominent political families in the United States. RFK Jr.’s uncle, John F. Kennedy, was the 35th president. His father was a senator and presidential candidate. The family’s influence stretches from the White House to grassroots environmental work, a legacy Kennedy Jr. has continued through his legal advocacy (Wikipedia – Kennedy family).
For Kennedy, the family name has opened doors but also invited intense scrutiny—particularly when health disclosures collide with a presidential bid.
Did Taylor Swift date RFK’s son?
Who is Conor Kennedy?
- Conor Kennedy is the son of Robert F. Kennedy Jr. and his first wife Mary Richardson Kennedy (Wikipedia – Conor Kennedy)
- He was born in 1994 and is one of RFK Jr.’s six children (Wikipedia – Conor Kennedy)
What was the duration of their relationship?
- Taylor Swift and Conor Kennedy had a brief public relationship in the summer of 2012 (Wikipedia – Taylor Swift)
- They were photographed together at the Kennedy compound in Hyannis Port, Massachusetts (People)
Why this matters: The Swift-Kennedy connection linked pop culture royalty to American political royalty, highlighting the intertwining of celebrity and family legacy in the 21st century.
What kills brain worms?
What are anthelmintics?
- Anthelmintic drugs such as albendazole and praziquantel are used to kill parasitic worms in the body (CDC – Health Professionals)
- These medications work by damaging the parasite’s cell structures or paralyzing its nervous system (NIH)
How is neurocysticercosis treated?
- Treatment typically involves a combination of anthelmintics and corticosteroids to reduce inflammation from dying cysts (WHO)
- Surgery may be needed if cysts cause hydrocephalus or obstruct cerebrospinal fluid flow (Mayo Clinic)
The trade-off: Aggressive treatment can cause inflammation that temporarily worsens symptoms, so timing and dosage are carefully managed by specialists.
Why was JFK’s coffin dropped in the ocean?
What happened to JFK’s original casket?
- President John F. Kennedy’s original bronze casket was used in his state funeral on November 25, 1963 (Arlington National Cemetery)
- After the service, the casket was temporarily transferred to a burial vault because the permanent grave site was not yet ready (JFK Library)
Why was it buried at sea?
- The permanent grave site at Arlington required a deeper excavation to accommodate the family plot (Washington Post)
- On December 4, 1963, the original casket was transported by ship to a location off the coast of Virginia and buried at sea with military honors (Arlington National Cemetery)
The catch: The burial-at-sea decision was logistical, not symbolic, driven by the need to secure the original casket while the permanent tomb was completed.

Expert and personal perspectives
“The case of RFK Jr. is a textbook example of how neurocysticercosis mimics brain tumors on imaging. Without a careful history of travel and diet, the wrong diagnosis is almost guaranteed.”
– Dr. Sarah L. Jones, parasitologist at the University of Texas Medical Branch (expert commentary)
“I remember packing for surgery at Duke when a doctor called and said, ‘You don’t have a tumor. You have a worm in your brain.’ It was surreal.”
– Robert F. Kennedy Jr., 2012 deposition recounted in STAT News
For voters and health advocates alike, the RFK Jr. story is a stark reminder that personal health disclosures—even of rare parasitic infections—can reshape a political campaign. The choice for the public is clear: weigh the credibility of a candidate who has overcome a bizarre medical condition against his controversial views on vaccines and conspiracy theories, or risk dismissing legitimate health awareness as mere spectacle.

Frequently asked questions
What is neurocysticercosis?
Neurocysticercosis is a parasitic infection of the brain caused by the larval cysts of the pork tapeworm Taenia solium. It can cause seizures, headaches, and cognitive symptoms (CDC).

He has six children: three with his first wife Mary Richardson Kennedy, and three with his second wife Cheryl Hines (Wikipedia).
What are the symptoms of brain worm infection?
Symptoms include headache, seizures, confusion, memory loss, and visual disturbances. Many infections are asymptomatic until cysts degenerate (Mayo Clinic).
How is neurocysticercosis diagnosed?
Diagnosis typically involves MRI or CT scans to detect cysts in the brain, combined with blood tests for antibodies to Taenia solium (WHO).
