Parkinson's, Explained Simply
Written and reviewed by Halston Juracka, RN-BSN, Certified Brain Injury Specialist and Kayla Juracka, RN-BSN · Updated August 2026
Most people think Parkinson's is a tremor. It is not, or at least it is not only that. Some people with Parkinson's never shake at all. This guide is written by nurses who have cared for people with Parkinson's at home, and it covers what the disease actually does, why the clock on the medication bottle matters more than almost anything else, and what families can do to keep someone safe and living well for as long as possible.
A free two-page version of this guide. Page two is a fridge sheet with a blank medication schedule you fill in with their actual dose times.

What is Parkinson's disease?
Parkinson's happens when certain cells deep in the brain slowly stop making dopamine, a chemical the brain uses to make movement smooth and automatic. Without enough dopamine, movements get smaller, slower, and stiffer, and the body stops doing automatically what it used to do without thinking.
Picture It This Way
Think of dopamine as the oil in a machine. Every part is still there and the motor still runs, but without oil the moving parts drag. Starting takes effort, motion is stiff, and small movements get lost first, the ones that used to happen without thinking: the swing of an arm while walking, the expression on a face, the loop of handwriting, the swallow. Parkinson's medication is the oil going back in, which is exactly why it works so well when it is on time and why everything drags when it is late.

The motor still runs. Without oil, the moving parts drag.
What are the signs of Parkinson's besides tremor?
The four main motor signs are tremor at rest, stiffness in the limbs, slowness of movement, and balance problems that come later. But families usually notice other things first, and some of the most disruptive symptoms have nothing to do with movement at all.
What families notice first
-
Handwriting getting smaller and cramped
-
A face that shows less expression
-
A voice getting softer
-
One arm not swinging while walking
-
Shuffling steps
-
Trouble turning over in bed
-
A stooped posture
The symptoms nobody warns you about
-
Constipation, often years before diagnosis
-
Trouble sleeping, including acting out dreams
-
Loss of smell
-
Low blood pressure on standing, which causes dizziness and falls
-
Depression and anxiety
-
Trouble swallowing, and drooling
-
In later stages, changes in thinking and memory
These often matter more day to day than the movement problems do. If thinking and memory become part of the picture, our guide to dementia is a natural companion to this one.
Why does medication timing matter so much?
Because Parkinson's medication does not stay in the body long. It works for a few hours and then wears off, so it is prescribed at specific times to keep a steady level. When a dose is even thirty to sixty minutes late, many people feel it: stiffness returns, walking gets harder, and freezing episodes start.
The One Thing to Remember
On time is the treatment. A dose 30 to 60 minutes late is felt.
This is the single most important thing a family can control.
Give the medication at the exact times prescribed, every day, including in the hospital, where late doses are common and cause real harm. Set alarms. Keep a written schedule taped where everyone can see it. If your loved one goes to a hospital or a facility, tell every nurse on every shift that Parkinson's medication times are not flexible, and bring the home schedule in writing.

Steady levels keep movement steady. A late dose shows up as a dip you can see.
Some newer medications, like Crexont, are extended-release forms designed to smooth out those on and off periods. Whatever the specific drug, the principle is the same: on time is the treatment.
What is freezing, and what helps?
Freezing is when the feet suddenly feel glued to the floor, usually while starting to walk, turning, or passing through a doorway. The person wants to move and cannot, and it is a major cause of falls.
What helps is giving the brain a different kind of signal, because the automatic movement system is what is failing, not the deliberate one.
When Someone Freezes
1
Stop
Do not push, pull, or hurry them.
2
Cue
Give the brain something deliberate to follow.
3
Move
Let them take the step themselves.
-
Count out loud, one, two, one, two
-
March in place before stepping off
-
Step over an imaginary line, or a laser pointer dot on the floor
-
Rock side to side to shift weight, then step
Any rhythm from outside the body can substitute for the rhythm the brain has stopped supplying.
Never pull on someone who is frozen.
That is how both people end up on the floor. Stop, cue, then move.
What can families do at home?
Movement is medicine here, more than in almost any other condition. Regular exercise, especially big, deliberate movements, has real evidence for slowing decline.
Ask the doctor for a referral to physical therapy trained in Parkinson's, and to speech therapy for voice and swallowing, because both weaken quietly and both respond to training.
Protect against falls, since low blood pressure, freezing, and shuffling stack together. Our falls guide covers the home walkthrough in detail. Watch swallowing closely: coughing during meals, a wet-sounding voice after drinking, or food staying in the mouth are all reasons to call. Take constipation seriously and build a bowel routine into the day. And be patient with speed. Everything takes longer, and rushing someone with Parkinson's makes movement worse, not faster.
When should you call the doctor?
Call the doctor's office today, not 911, but today, for any of the following.
Call the Doctor Today
-
New or worsening freezing, or falls
-
Medication that no longer seems to last until the next dose
-
Coughing or choking with meals, or a wet voice after drinking
-
New confusion, hallucinations, or seeing things that are not there, which can be the disease or the medication and needs sorting out
-
Dizziness on standing
-
New or worsening depression
-
Unexplained weight loss
-
Any sudden change in movement, because sudden changes in Parkinson's usually mean something else is going on, most often an infection
When is it 911?
Parkinson's itself moves over months and years. Anything dramatic that happens over hours is something else, and it is an emergency.
Call 911 Now
-
A fall with a head strike, especially on blood thinners
-
Choking, or difficulty breathing
-
Sudden inability to move or speak, which may be a stroke rather than Parkinson's
-
High fever with rigid muscles and confusion, which is rare but serious and can happen when Parkinson's medication is stopped abruptly
-
Any sudden dramatic change over hours
Never let Parkinson's medication be stopped abruptly without a doctor directing it, including during a hospital stay.
What should families expect over time?
Parkinson's is a long disease, often ten to twenty years or more, and it moves at a different pace in every person.
Early on, medication works well and life continues largely as it was. In the middle stage, medication effects become less even, freezing and falls appear, and daily activities take more time and more help. Later, walking, swallowing, and thinking are affected, and the daily care load becomes significant.
The families who navigate this best plan one stage ahead, get therapy involved early rather than after a crisis, and bring in help before exhaustion rather than after. Nothing about accepting help means giving up. It is what keeps someone home.
Where can Las Vegas families turn?
The Cleveland Clinic Lou Ruvo Center for Brain Health downtown specializes in Parkinson's and movement disorders and is a genuine national resource in our own city. The Parkinson's Foundation offers education and a free helpline.
Local exercise programs designed for Parkinson's, including boxing-style and big-movement classes, exist across the valley and are worth finding.
And when a family needs trained help at home, caregivers who understand medication timing, freezing, and fall risk, with a nurse watching the whole picture, that is the work of our practice.
