7 Signs Your Shaky Hands Are Due to Parkinson’s

This disease is most often linked with tremors, but there’s more to a diagnosis


(This article appeared previously on Grandparents.com.)

When her right hand started trembling uncontrollably, 68-year-old Sherri Fowler (not her real name) began to fear that she was developing Parkinson’s disease, the progressive disorder of the nervous system that plagued Muhammad Ali, and led actor Michael J. Fox to create a foundation that is working toward a cure for the degenerative disease.

But Fowler may have gotten ahead of herself.

Some Parkinson’s patients get treated for depression because of lack of expression and the overall slowness of their movements.

“There are many causes of tremor and Parkinson’s disease is only one,” explains Dr. Nikolaus McFarland, assistant professor of neurology and chief of the Movement Disorders Division of the University of Florida College of Medicine. “Indeed, one of the first symptoms of Parkinson’s disease may be tremor, but there are many other key features to look out for. To diagnose Parkinson’s disease, we typically look for a constellation of symptoms including rest tremor, rigidity [or stiffness], slowed movement and postural instability. Patients may have some or all of these features, making the diagnosis tricky at times.”

The disease affects about 1 million Americans and usually strikes people who are older than 60. It develops gradually and is a breakdown of vital brain nerve cells that produce the neurotransmitter dopamine, which is important for normal brain function, including movement, learning and emotion. Disruption of signals in the brain is what leads to involuntary tremors.

Sherri Fowler discovered that her tremor was related to a medication she was taking. Tremors can be caused by endocrine issues, thyroid issues, vascular disease, inflammation, diabetes, anxiety or even some psychiatric issues, McFarland says. Consult your doctor to get a diagnosis.

If you have a tremor, you should see a doctor to find out the root cause.

These are the other symptoms of Parkinson’s disease:

1. Postural Instability

People with Parkinson’s disease have trouble standing up straight or maintaining their balance. A small push can send them tumbling. A stooped posture is common along with a slow, shuffling gait (more on that below).

2. Change in Speech

Commonly, people with Parkinson’s disease experience a change in the tone of their voice. It typically gets softer and becomes more monotone, McFarland says. You may not notice it yourself, but if your family members are saying, “Speak up!” or your friends ask you to repeat yourself, that may be an indicator that your voice’s timbre has changed.

3. Change in Handwriting

Is your handwriting becoming small and illegible? You may be developing what is called micrographia. You may notice your handwriting trailing off the page, getting smaller and smaller and harder to read.

4. A Shuffling Gait

If you have trouble walking, or your steps have become more of a shuffle than a walk, that could be a symptom of Parkinson’s disease. Some patients experience what doctors call “freezing.” “These are rigid spells where a person gets frozen in place,” McFarland says. “You turn or get to a threshold and get frozen in place, feeling like you can’t possibly take another step. You need some cue, be it a sound, tactile or visual [like a laser line to step over], to get moving again.”

5. A Lack of Facial Expression

“Friends and family tend to notice this first,” says McFarland. Patients often tell him, “I’ve been told I look like I’m depressed all the time.” This “mask” expression is often the result of small facial muscles being unable to move.

In fact, says McFarland, some Parkinson’s patients get treated for depression because of this lack of expression and the overall slowness of their movements. “It can be misconstrued,” he says, but notes that depression and anxiety often go hand in hand with Parkinson’s. “It absolutely needs to be treated and taken seriously,” he adds. But some patients who are treated solely for depression may not be getting all the help they need if they are also dealing with Parkinson’s.

6. Loss of Sense of Smell

If you find that your nose doesn’t pick up scents as well as it once did, mention it to your doctor. “This is something that has to be carefully interpreted,” says McFarland. “It doesn’t mean if you lose your sense of smell that you’ll receive a diagnosis of Parkinson’s, but it is a risk factor.”

7. Trouble Sleeping

Many Parkinson’s patients experience sleep disturbance. “Restless leg is not uncommon and is characterized by a nondescript discomfort, or restless feeling, in the legs, causing you to want to move. The feeling occurs at rest, when lying down to sleep, and can make it very difficult to fall asleep,” says McFarland. “Some patients suffer from active dreams, yelling, punching or kicking. Normally when we dream, only our eyes are moving and our body is flaccid. This state is called REM sleep for Rapid Eye Movement. In Parkinson’s, active dreams, or what is called REM sleep behavior disorder, can result in arousals, potential injury and overall poor sleep quality.” These symptoms can occur years before a Parkinson’s diagnosis, or they can crop up later.

This is a likely explanation for why Parkinson’s patients also report a deep fatigue as part of their symptoms. They may be in bed for eight hours, but they may not be experiencing enough restorative sleep.

Getting a Diagnosis

There is no blood test for Parkinson’s. Currently, the only available test for Parkinson’s is a type of brain scan called DaTscan. In contrast to CT or MRI imaging, which show detailed brain structures, the DaTscan specifically looks at the dopamine system. While it can be useful to diagnosis Parkinson’s, it is not specific to Parkinson’s disease. A normal scan, however, can help rule out Parkinson’s.

The diagnosis of Parkinson’s disease, however, remains primarily clinical, based on symptoms and signs. In most cases, a neurologist will not need to order a DaTscan unless there is something unusual or unexpected about the case. In cases where there is a question about whether a patient has Parkinson’s, the patient should consider seeing a movement disorders specialist. To find one near you, visit Partnersinparkinsons.org.

Parkinson’s disease is not curable but medication can ease its symptoms and give patients good quality of life for a long time, says McFarland. “For decades we’ve treated the disease by replacing the dopamine that is lost. These are very effective treatments.”
