Bradykinesia is impairment of voluntary motor control and slow movements or freezing.
It’s most commonly a symptom of Parkinson’s disease or a side effect of certain medications. It is one of the main symptoms doctors will look for when diagnosing Parkinson’s.
The symptoms of bradykinesia include unusually slow movements. However, there are other symptoms that are common with the condition. These symptoms include:
- shuffling when walking
- dragging one or both feet when walking
- having little or no facial expressions
- freezing — muscle reactions may slow to the point that the muscles become immobile, or freeze, for a period of time
- difficulty with tasks that are repetitive in nature, like tapping fingers or clapping hands
- difficulty getting ready each day (e.g., buttoning clothes, brushing teeth, styling hair)
For those living with Parkinson’s disease, bradykinesia is one of the causes of losing their ability to speak clearly. Their voice will become softer and softer over time, and their words will become more difficult to understand clearly.
Bradykinesia also contributes to the risk of falling in people who have Parkinson’s disease.
The test used for bradykinesia is called the bradykinesia akinesia incoordination test, also known as the B.R.A.I.N. test.
During this test, you are asked to tap keys quickly on a keyboard with alternating fingers for one minute. Your scores on the test will determine your diagnosis.
The scores include the number of correct keys hit, the number of wrong keys hit, the time it takes to hit the keys, and the time that lapses between hitting each key.
This test is considered reliable for telling doctors what stage of Parkinson’s you are in and if you have bradykinesia. There is not a set test yet to initially diagnose Parkinson’s disease.
Parkinson’s and its symptoms currently can’t be cured. However, the symptoms can be managed somewhat with medications.
The most helpful medications for bradykinesia are those that increase dopamine action. Some of the medications that use dopamine or act just like dopamine to get the same reaction are:
- dopamine agonists
- MAO-B inhibitors
There are a number of other medications your doctor can try until you find the right one for you.
However, finding the right medication will be a constant challenge because these types of medications become less effective over time. Your doctor will monitor you to adjust the dosage or change medications as needed.
There’s also a surgical procedure known as deep brain stimulation that may be used for certain people living with Parkinson’s. This treatment involves surgically placing electrodes into specific locations in your brain.
Once the electrodes are in place, you will have electrical impulses sent to stimulate the brain at the electrode sites. This treatment is normally reserved for those with severe Parkinson’s who do not respond well to traditional medications.
Lifestyle remedies for symptom management
Whether you are taking medications or not, there are lifestyle changes and steps you can add at home as part of your treatment plan.
However, you should be sure to talk with your doctor before adding anything to your Parkinson’s treatment plan. Anything that helps treat your Parkinson’s disease will also help with your bradykinesia.
Some of these lifestyle or home treatments include:
- eating a nutrient-rich diet
- eating a diet high in fiber
- doing physical therapy with exercises that increase your strength, balance, and flexibility
- taking necessary steps to help avoid falling
Bradykinesia often occurs as a side effect of certain drugs (such as
Both studies gave compelling evidence to support their findings, but more research is needed before determining an exact cause.
A cure for Parkinson’s disease or its symptoms, which includes bradykinesia, has not yet been found. However, there are medications, treatments, and lifestyle changes that can help you manage it.
Talk with your doctor regularly and let them know of any changes you or those around you notice. It’s important to always keep your doctor updated on the effectiveness of your current medication.
