50 Fun Facts About Parkinson's Disease

Which actor hid a Parkinson's diagnosis for seven years, then founded its biggest research charity?

Michael J. Fox was diagnosed in 1991 but only went public in 1998, while starring in the sitcom Spin City. The foundation he launched in 2000 has raised more than $2 billion for research.

Which heavyweight champion with Parkinson's syndrome lit the flame at the 1996 Atlanta Olympics?

Muhammad Ali lit the Olympic cauldron in Atlanta 12 years after his diagnosis. He and his doctors disputed reports that blows taken in the ring had caused his illness.

Which sense, often dulled years before Parkinson's is diagnosed, does Joy Milne use to detect it?

Smell is how Joy Milne picks out skin swabs taken from people with Parkinson's; she first noticed a change in her husband's scent. Her nose led chemists to a test that analyses sebum, the skin's natural oil.

James Parkinson first described the disease in an 1817 essay, calling it by what name?

The shaking palsy was his plain-English name for what he also called paralysis agitans. No portrait of Parkinson is known, so the faces sometimes printed beside his name belong to other men.

Which pope with Parkinson's was beatified after a French nun was declared cured of the same disease?

John Paul II was confirmed to have Parkinson's in 2001. Sister Marie Simon-Pierre, bedridden by the same illness, recovered after her community prayed to him, the miracle accepted for his beatification.

Which flower symbolises Parkinson's, after a grower named a red variety for James Parkinson?

Tulip growers gave the cause its emblem: the red 'James Parkinson' variety was registered in 1981 and adopted as the symbol in 2005. World Parkinson's Day falls on the surgeon's birthday, 11 April.

Which neurologist wrote Awakenings, about immobile patients briefly revived by a Parkinson's drug?

Oliver Sacks gave it to survivors of the 1920s encephalitis lethargica epidemic at a hospital in the Bronx. Robin Williams played a doctor based on him in the 1990 film of the book.

Parkinson's is the second most common neurodegenerative condition; which one is more common still?

Alzheimer's is the only one that is more common. Parkinson's does not strike evenly, though: men are about 1.5 times more likely to have it than women.

Micrographia, which often appears before other Parkinson's symptoms, changes which everyday skill?

Handwriting that turns small and cramped is called micrographia. James Parkinson may have spotted it himself, describing "the hand failing to answer with exactness to the dictates of the will".

Which drink do studies most consistently link to a lower risk of developing Parkinson's?

Coffee drinkers develop the disease less often, and caffeine is the suspected reason. Exercise and diets rich in fruit, vegetables and fish are linked to lower risk as well.

Parkinson's kills dopamine-making cells in which midbrain region, named for its dark pigment?

Substantia nigra is Latin for "black substance". By the time movement symptoms appear, 50 to 80 per cent of its dopamine-producing nerve cells have already been lost.

Which clumps found in Parkinson's nerve cells are named after the neurologist who discovered them?

Lewy bodies are named for Frederic Lewy, who spotted the microscopic particles in affected brains in 1912. A single nerve cell can hold more than one of them.

Which drug, first isolated from broad beans, has been the main Parkinson's therapy since the 1960s?

Levodopa works because nerve cells turn it into dopamine, topping up the brain's dwindling supply. It is usually taken with carbidopa, which cuts nausea and lets a smaller dose do the job.

Which Parkinson's surgery wires electrodes in the head to a pulse generator implanted in the chest?

Deep brain stimulation sends electrical pulses from a battery pack under the skin of the chest. Patients are often kept awake during the operation so their feedback can guide where each electrode goes.

In stage one of Parkinson's five stages, tremor and other movement symptoms appear where?

One side of the body is affected first, and symptoms are mild enough not to interfere with daily activities. At stage two they reach both sides or the midline, such as the neck and trunk.

Which problem is the hallmark of stage three, the midpoint of the five stages of Parkinson's?

Loss of balance marks stage three, showing as unsteadiness when the person turns or is pushed while standing. This kind of trouble, and the falls it brings, typically arrives after about 10 years.

People with REM sleep behaviour disorder, a strong predictor of Parkinson's, do what in the night?

They act out their dreams, shouting, kicking or punching, because the paralysis that normally holds the body still in REM sleep is lost. It can begin years or even decades before Parkinson's shows itself.

Which French neurologist, a teacher of Sigmund Freud, had the disease renamed after James Parkinson?

Jean-Martin Charcot pressed for the change in the 1870s, after years spent refining the description of the illness. He also added slowness of movement to the list of core signs.

Which habit, harmful in nearly every other way, is strongly linked to a lower risk of Parkinson's?

Smoking is tied to fewer cases, though nobody is sure why. Tobacco may protect nerve cells, or the link may run the other way, with the earliest phase of the disease changing who keeps the habit.

A bad batch of what kind of drug gave users in California sudden Parkinson's symptoms in the 1980s?

A synthetic opioid called MPPP was to blame: careless chemistry left it laced with MPTP, a toxin that mimics Parkinson's almost exactly. Labs still use MPTP to recreate the disease and test treatments.

Which Black Sabbath singer with Parkinson's gave his farewell concert seated on a black throne?

Ozzy Osbourne, no longer able to stand, sang from the throne at Birmingham's Back to the Beginning concert in July 2025. He had gone public with his diagnosis in January 2020.

Which singer, subject of the musical A Beautiful Noise, quit touring after a Parkinson's diagnosis?

Neil Diamond announced in January 2018 that he would stop touring. He has stayed active in raising awareness of the disease, and the Broadway show tells his life story through his own songs.

Which Scottish comic, a record 15-time guest on TV's Parkinson, later developed Parkinson's himself?

Billy Connolly, known as the Big Yin, revealed in 2013 that he was being treated for early symptoms. He retired from stand-up in 2018 and has since made a name as an artist.

Which US attorney general, the first woman in the post, learned she had Parkinson's while in office?

Janet Reno learned she had the disease in 1995 and stayed on until 2001, the second-longest tenure of any attorney general. She took up inline skating the year after her diagnosis.

Which Hall of Fame quarterback revealed his Parkinson's diagnosis while testifying to Congress?

Brett Favre broke the news at a 2024 hearing into misspent welfare funds in Mississippi. Years earlier he had wondered aloud whether his memory lapses were a legacy of the hits he took as a player.

Which actress played a young Parkinson's patient opposite Jake Gyllenhaal in Love & Other Drugs?

Anne Hathaway played Maggie Murdock, who falls for a drug salesman in 1990s Pittsburgh. In one scene Maggie wanders into a Parkinson's support group meeting across the street from a medical conference.

Which actor was Oscar-nominated as a patient revived by a Parkinson's drug in the film Awakenings?

Robert De Niro played Leonard Lowe, who wakes from a catatonic state after decades and must adjust to an unfamiliar time. The 1990 film was also nominated for Best Picture.

Which Google figure, whose mother developed Parkinson's, has given over $1 billion to research?

Sergey Brin began in 2008 with a gift to the University of Maryland School of Medicine, where his mother, Eugenia, was being treated for the disease.

Slowness of movement is one of the four cardinal signs of Parkinson's; what is its medical name?

Bradykinesia is the most disabling symptom early on, turning fine tasks such as sewing or dressing into hard work. Doctors need to see it, along with stiffness or tremor, to make the diagnosis.

Paraquat and rotenone, both linked to a higher Parkinson's risk, are what kind of farm chemical?

Pesticides like these poison mitochondria, the power plants of the cell, and Parkinson's is more common where they are heavily used. That may explain a long-noticed link with rural living.

Unlike most tremors, the classic Parkinson's tremor is at its strongest when the hand is doing what?

Resting is when it peaks: the shake is strongest in a limb at rest and disappears with deliberate movement and in sleep. About 30 per cent of people have no tremor at all when the disease begins.

Parkinson's classic hand tremor, thumb circling on finger, is named after which old pharmacy task?

Rolling pills between thumb and finger was how pharmacists once made them by hand. The tremor repeats that small circular motion four to six times a second.

What name is given to the Parkinson's symptom where the feet suddenly feel glued to the floor?

Freezing usually lasts less than 10 seconds. Oddly, rhythm can break the spell: marching to a command or stepping in time to a beat often gets the legs moving again.

What everyday name do doctors use for hypomimia, the loss of facial expression seen in Parkinson's?

Masked face, or hypomimia, comes from stiff, slowed facial muscles rather than any lack of feeling. People who have had too much Botox are sometimes wrongly thought to show the same sign.

Which machine part names the jerky stiffness doctors feel when bending a Parkinson's patient's arm?

Cogwheel rigidity feels like a series of short jerks as the arm is moved. A second kind, known as lead pipe, is a steady resistance all the way through the movement.

Which digestive complaint is a common Parkinson's symptom that can appear years before any tremor?

Constipation arises because the disease also affects the nerves that control the gut. Doctors suggest a fibre-rich diet and plenty of fluids to ease it.

About nine in ten Parkinson's cases are described as idiopathic; what does that medical term mean?

Of unknown cause is the honest answer for about 90 per cent of cases. Only 5 to 10 per cent run in families, though several genes that raise the risk have been identified.

Dopamine itself is useless as a Parkinson's drug because it cannot cross which protective boundary?

The blood–brain barrier keeps it out, so patients are given a precursor that slips across and is converted on the far side. For the same reason, dopamine in food never reaches the brain.

Dopamine agonists, one class of Parkinson's drug, can trigger which surprising behaviour?

Compulsive gambling, along with overspending, overeating and hypersexuality, can appear in people with no history of such behaviour. Impulse-control problems are a recognised risk of the whole drug class.

Parkinson's disrupts which movement-tuning group of nuclei, one that includes the striatum?

The basal ganglia are clusters of nerve cells that help start and smooth out movement. Huntington's attacks the same circuit from another end, damaging the striatum itself.

Which two doctors gave their names to the five-stage Parkinson's scale they published in 1967?

Hoehn and Yahr set it out in the journal Neurology. Margaret Hoehn and Melvin Yahr ranked patients by level of disability, and half-steps such as 1.5 and 2.5 were added later.

Which Swedish Nobel laureate proved dopamine is a brain messenger, leading to Parkinson's drugs?

Arvid Carlsson found in the 1950s that draining dopamine left animals unable to control their movements, much like Parkinson's patients. He shared the 2000 Nobel Prize in Physiology or Medicine.

Which Parkinson's drug began as a flu antiviral before its effect on movement was found by chance?

Amantadine was approved against influenza A in 1966, and its benefit in Parkinson's was noticed two years later. It is now used mainly to calm the involuntary movements that long treatment can bring.

Long exposure to which metal, a hazard in some mines, causes a Parkinson's-like condition?

Manganese poisoning, seen mostly in mining and smelting, brings neurological symptoms that resemble Parkinson's. Welders have also sued over fumes they say carried dangerous levels of the metal.

Outside medicine, James Parkinson avidly collected what, with several species named after him?

Fossils so absorbed him that he wrote his own introduction to them, because little existed in English. In 1807 he attended the first meeting of the Geological Society of London, and an ammonite bears his name.

Which sport is the basis of Rock Steady, a non-contact fitness class for people with Parkinson's?

Boxing training without the fighting is the idea: Scott Newman began the classes in Indianapolis in 2006, after his own diagnosis at 40. They have since spread to hundreds of gyms around the world.

The Lee Silverman therapy for the fading voice of Parkinson's drills patients in doing what?

Speaking loudly is the whole focus of the programme, called LSVT LOUD, which runs for sixteen one-hour sessions over four weeks. A spin-off named LSVT BIG trains larger body movements.

Which nutrient competes with the main Parkinson's drug for absorption, so doses come before meals?

Protein shares the drug's transport system in the gut and on the way into the brain, so a big steak can crowd a dose out. Some patients save most of the day's allowance for the evening meal.

What do people with Parkinson's call the spells when a dose fades and symptoms creep back?

Off periods are the flip side of "on" time, when the medication is working well. After years of treatment the switch between the two can become sudden and hard to predict.

Which misfolded molecule is the main ingredient of the clumps inside nerve cells in Parkinson's?

Alpha-synuclein normally helps nerve cells release their chemical signals. A 2023 study showed that its abnormal form can be detected before any symptoms of Parkinson's begin.
