TREMOR
Rhythmic, uncontrollable jerking that affects a part of the body, beginning mainly in the hands, fingers, jaw, or feet.
What Is an Earthquake?
Tremors are one of the first symptoms experienced by approximately 75% of people with Parkinson's disease (PD), along with rigidity and bradykinesia (slowness of movement). Their presentation can range from mild to severe.
There are different types of tremors commonly observed in PD, including resting tremor, action tremor, and postural tremor.
Resting tremor: This is the most common type in PD and usually occurs in the hands as a rolling motion, especially between the thumb and index finger (known as "pill rolling"), when the person is at rest.
Action tremor: This type of tremor only manifests when the patient performs a movement or activity, such as reaching for an object.
Postural tremor: This tremor occurs when a person holds a position against gravity and can interfere with daily activities.
How to Manage a Tremor
Tremors can be unpredictable; however, they can be managed through a combination of medication, lifestyle adjustments, such as stress management or the use of assistive devices, and therapy.
What Causes a tremor?
In people with Parkinson's, there is a shortage of dopamine. This occurs because certain nerve cells in the brain that produce dopamine have died. The decrease in dopamine levels causes movement problems and the characteristic symptoms of Parkinson's disease (PD).
Factors such as stress, fatigue, and medication fluctuations can make tremors worse. Although not everyone experiences this symptom, it is important to talk to a doctor if new changes occur.
