Tremors are a condition of shaking that is often considered normal and harmless. Many people attribute tremors to fatigue, stress, or aging. However, in the medical world, tremors can be a symptom of neurological disorders, including Parkinson's disease. One type of tremor that requires special attention is resting tremor , known as a hallmark of Parkinson's.
In healthcare, tremors are often the initial reason someone seeks medical attention. Therefore, understanding the types of tremors, especially Parkinson's tremors, is crucial to aid early detection and prevent delays in treatment.
What Is Resting Tremor?
Resting tremor is a condition where the hands or other body parts shake even when not in use. For example, when the hands are placed in the lap, when relaxing while watching television, or when the body is in a still position.
What makes this tremor different from a normal tremor is its pattern. The tremors appear when the body is relaxed, then diminish or disappear momentarily when the hand is moved, and then reappear.
Medically, this type of tremor pattern is a key feature of Parkinson's disease. Therefore, resting tremors should not be dismissed as normal shaking, especially if they occur repeatedly and persist.
Characteristics of Parkinson's Tremor
Tremors in Parkinson's have quite distinctive characteristics and are different from other types of tremors, including:
- Tremors appear at rest or when the body is still
- Tremors start on one side of the body, left or right and can occur in the hands or feet.
- Fine, rhythmic, and consistent tremor movements
- Fingers can move as if they are rolling a small object
- Tremors can become more noticeable when stressed, anxious, or tired.
As the disease progresses, the tremors may spread to other parts of the body.
When Should Tremors Be a Concern?
Tremors need to be watched out for if they appear continuously, especially during rest, last for several weeks, occur on one side of the body, and are accompanied by changes in movement, posture, or balance.
In these conditions, a medical examination, especially by a neurologist, is highly recommended. Early testing helps determine whether the tremor is related to Parkinson's or caused by another condition.
Tremors at rest are a common, often overlooked, sign of Parkinson's. While tremors don't always indicate Parkinson's, understanding the characteristics of Parkinson's tremors can help raise awareness and encourage early detection.
