For many, the image of Parkinson’s disease is defined by the visible: the rhythmic tremor of a hand, the stiffness of a gait, or the unhurried, labored movement known as bradykinesia. But actor Ryan Reynolds is sharing a different, more invisible side of the disorder—one that blindsided his family and left his father, James, isolated in a reality no one else could see.
James Reynolds was diagnosed with the nervous system disorder in 1993 at the age of 52. For a decade, the family managed the expected physical decline. However, they were unprepared for the psychological shift that followed. James began experiencing Parkinson’s disease hallucinations and delusions, seeing and hearing things that did not exist and weaving complex, often paranoid, narratives around them.
The experience was jarring for the family, particularly for Ryan’s mother, Tammy, who served as the primary caregiver. James would describe nonexistent passengers in the back seat of the car or claim that neighbors were spying on his wife. For the family, these episodes were confusing and frightening, often mistaken for a sudden onset of dementia or a general loss of mental faculty.
As a physician, I recognize this as a critical gap in public health literacy. While the motor symptoms of Parkinson’s are widely recognized, the non-motor symptoms—including cognitive changes, depression, and psychosis—are frequently overlooked during initial diagnoses, leaving families to navigate a “matrix” of emotional distress without a medical roadmap.
The Hidden Prevalence of Parkinson’s Psychosis
The struggle the Reynolds family faced is more common than most realize. Research indicates that roughly half of all people living with Parkinson’s will experience some form of hallucination or delusion during the course of their illness. These episodes are not always a sign of dementia, though the two can co-occur.
In Parkinson’s, neurons in the brain slowly break down and die, disrupting the communication between the brain and the body. Hallucinations often arise from a combination of the disease’s progression and the highly medications used to treat the physical symptoms. Dopamine agonists, which help manage motor functions, can inadvertently trigger psychotic symptoms by overstimulating certain pathways in the brain.
For James, these delusions created what Ryan describes as a “chasm” in their relationship. Because the symptoms were not clearly explained to the family by medical professionals at the time, James became, in Ryan’s words, “an unreliable narrator in his own life.” This lack of clarity often leads caregivers to try and “pacify” the patient rather than provide the targeted empathy and medical intervention required.
The treatment of these symptoms has also evolved. Historically, antipsychotic drugs were used to curb hallucinations, but many of these medications block dopamine, which can severely worsen the physical tremors and rigidity of Parkinson’s. Modern medicine has since introduced more targeted treatments that aim to reduce psychosis without compromising motor control.
The Burden of the ‘Strong, Silent Type’
Beyond the clinical challenges, the Reynolds family dealt with a generational barrier: the stigma of vulnerability. James, a former police officer and food broker, belonged to a generation of men who viewed illness as a source of shame. Ryan recalls that his father rarely used the word “Parkinson’s,” treating the diagnosis as a secret rather than a medical reality.
This reticence created a profound sense of loneliness for James. When a patient is unable or unwilling to communicate their internal experience, the isolation is doubled—they are trapped by the disease and by their own silence. Ryan notes that if the family had known these hallucinations were a standard part of the disease’s nuance, they could have offered a “tender grit” and a more productive dialogue.
The emotional toll extended heavily to Tammy, who is now 81. Caregiving for a spouse with Parkinson’s often requires a total dissolution of one’s own desires and hopes to accommodate the round-the-clock needs of the patient. Ryan and his three brothers eventually “descended on the house” to support their mother, recognizing that the psychological weight of managing delusions is often more exhausting than the physical labor of caregiving.
Turning Grief into Public Utility
James passed away at 74, shortly after the birth of Ryan’s eldest daughter, also named James. In the years since, Ryan has leveraged his platform to ensure other families aren’t blindsided by the cognitive symptoms of the disorder. He has collaborated with The Michael J. Fox Foundation, citing the impact that Michael J. Fox’s transparency has had on the global conversation surrounding the disease.
Ryan describes this effort through the Japanese concept of koeki—the act of doing something that benefits the world. By sharing the “tough stuff,” including the reality of hallucinations and the strain on caregivers, he aims to shift the temperament of the diagnosis from one of shame to one of managed optimism.
The goal is to encourage a symbiotic approach to treatment, where both physical and psychological symptoms are addressed in tandem. When families understand that a delusion is a chemical byproduct of a brain disorder rather than a personal failing or a sign of “losing one’s marbles,” the quality of life for both the patient and the caregiver improves significantly.
As research continues into the biological markers of Parkinson’s, the medical community is moving toward earlier detection of non-motor symptoms. The next major frontier in PD care involves refining personalized medication schedules to balance motor stability with cognitive clarity, reducing the incidence of psychosis in newly diagnosed patients.
