A shaking hand is not automatically Parkinson's. Essential tremor is the more common of the two, and they behave differently in six specific ways. The first is when the shaking happens.

Action versus rest. Essential tremor is worst when you are using the hand. Parkinson's tremor is worst when the hand is resting and lessens when you use it. Cleveland Clinic

Essential tremor is common. It affects roughly 1 percent of people worldwide and about 5 percent of people over 60. It is the most common form of tremor. Cleveland Clinic

The cup rattles on the saucer, and the first word that comes to mind is the wrong one.

Most hand tremor is not Parkinson's. Essential tremor is the most common kind, and it behaves in ways you can watch for yourself.

Here are the six differences a neurologist looks for, what essential tremor actually looks like day to day, and the four symptoms that point the other way.

The Difference

Six Differences a Neurologist Looks For First

Cleveland Clinic sets the two conditions side by side. Six rows, six things you can observe without a scan.

When the shaking happens. Essential tremor is worst when you use the affected part and lessens at rest. Parkinson's tremor is worst at rest and lessens in use.
Which side. Essential tremor usually shows on both sides, with one slightly worse. Parkinson's tremor is often asymmetric, affecting one side much more.
Head and neck, or legs and feet. Essential tremor often involves the head and neck and almost never the legs and feet. Parkinson's rarely affects head and neck and sometimes involves legs and feet.
Handwriting. Essential tremor makes writing shaky but not unusually small. Parkinson's can make handwriting unusually small, which has its own name, micrographia.
Family history. Essential tremor often runs in families. Parkinson's only rarely does.
What else comes with it. Essential tremor is tremor and nothing else. Parkinson's also brings slowed movement, stiffness, and changes in walking and balance.

5% over 60

Essential tremor affects about 1 percent of people worldwide and about 5 percent of people over age 60. It is the most common form of tremor and one of the most common movement disorders.

No single row settles it. The pattern across all six is what a clinician reads.

The Pattern

What Essential Tremor Looks Like Day to Day

Mayo Clinic describes the shape it takes. Symptoms begin gradually and are usually more noticeable on one side. They worsen with movement. They almost always start in the hands.

They can include a yes-yes or no-no nodding of the head. And they may get worse with stress, fatigue, caffeine or extreme heat and cold.

Cleveland Clinic adds the inheritance figure that often decides the conversation with family.

About half of all essential tremor cases are inherited.

The Other Side

The Four Symptoms That Point Toward Parkinson's

Parkinson's is not a tremor diagnosis. The National Institute on Aging names four main symptoms, and tremor is only the first one.

Tremor in the hands, arms, legs, jaw or head. Muscle stiffness, where a muscle stays tight for a long time. Slowness of movement. And poor balance, which can lead to falls.

NIA lists other symptoms too. Low mood. Trouble swallowing, chewing and speaking. Bladder or bowel changes. Skin problems. Most people get the disease after age 60.

That is why a tremor on its own rarely settles anything, in either direction.

The Debunk

Three Tremor Beliefs That Delay the Right Answer

Three corrections worth having before the appointment.

A shaking hand means Parkinson's. Cleveland Clinic calls essential tremor the most common form of tremor and one of the most common movement disorders. Parkinson's is the diagnosis people jump to, not the likeliest one.

There is a test that confirms it. There is not, at least for essential tremor. Cleveland Clinic says the diagnosis rests on symptoms and a neurological exam, and that blood and imaging tests exist to rule other conditions out, especially thyroid problems.

A drink steadies the hand, so alcohol is a treatment. Cleveland Clinic notes small amounts of alcohol may help tremors and then says explicitly that you should not self-treat with it, both because of the risk of misuse and because some tremor medications interact dangerously with alcohol.

📋Your Coach's Recommendations

Write down when the shaking happens.

Reaching for a cup, or sitting still with your hands in your lap. Cleveland Clinic puts that distinction in the first row of its comparison, and it is the single most useful thing you can bring to an appointment.

Bring a handwriting sample and a family history.

Two more of the six rows. Shaky but normal-sized writing, and tremor that runs in the family, both lean toward essential tremor. Unusually small writing leans the other way.

Ask for the rule-out tests, not a label.

Cleveland Clinic says no test confirms essential tremor, and that blood and imaging tests are used to rule out other causes such as thyroid conditions. Ask which ones you need and what each one is checking for.

Frequently Asked Questions

How do I tell essential tremor from Parkinson's at home?

Watch when the shaking happens. Cleveland Clinic puts it first: essential tremor is worst when you use the hand and lessens at rest, while Parkinson's tremor is worst at rest and lessens in use. That observation is a starting point for the appointment, not a diagnosis.

Is essential tremor dangerous?

Cleveland Clinic says the tremor itself is not dangerous, but it can become severe enough to disrupt eating, drinking, dressing and writing. It is usually progressive, worsening slowly over years.

Will my children get it?

Cleveland Clinic says about half of all essential tremor cases are inherited, and that it appears to be autosomal dominant, meaning a parent who carries the gene passes about a 50 percent chance of inheriting it.

Does caffeine really make it worse?

Mayo Clinic lists caffeine alongside emotional stress, fatigue and extreme temperatures as things that may worsen essential tremor. Cleveland Clinic makes the same point about anxiety, fatigue and stress.

At what age does each one usually start?

Cleveland Clinic says essential tremor is most likely to start between ages 10 and 19 or between 50 and 59, and affects about 5 percent of people over 60. NIA says most people first develop Parkinson's after age 60.

What should I ask at the appointment?

Ask whether your tremor is an action tremor or a rest tremor, whether anything besides tremor showed up on the exam, which blood or imaging tests are being used to rule other causes out, and what would change the answer.
