The symptoms that can occur early in in the disease and provide evidence that the tremor is part of PD include: Perhaps most important of all in deciding whether a tremor is consistent with PD or another disorder is determining whether other symptoms of PD are present, in addition to the tremor. Although this is a pattern that is sometimes seen, there are many other characteristic rest tremors of PD, such as bending and unbending at the wrist or rotation at the wrist.

This refers to a repetitive circular motion of the thumb against the other fingers. The term “pill rolling” is often used in reference to a PD tremor. PD tremors do not commonly affect the head or neck (which results in the head moving in a “yes-yes” or “no-no” direction) or vocal cords (which results in a shaky voice when holding a note). Typically, the tremor starts on one side and even if, as the disease progresses, it begins to affect the other side, a difference between the two sides of the body tends to remain. Almost universally, the tremor of PD is asymmetric, meaning that it is different on each side of the body. Affected body partĪ PD tremor most commonly affects the fingers or hand, but can also affect the legs and jaw. Therefore, the frequency of the tremor is not characteristic enough to use as a means of diagnosing a PD tremor. This can be variable however, with younger people tending to have faster tremors. Identifying a tremor Frequency of tremorĪ PD tremor typically has a frequency of about 3-6 Hz, which means that the body part moves back and forth about 3-6 times a second. Therefore, if you have a tremor, it is best to get checked out by a neurologist. However, to the untrained eye, it can be very difficult to distinguish between these tremors. So if a person can accurately distinguish between these entities, this can be an important clue in diagnosing PD. This is referred to as a re-emergent tremor.Īlthough there are many diseases that cause tremor in general, there are very few that cause rest tremor and re-emergent tremor. The tremor tends to stop during the movement and then resume in the new posture. The other is when the limb is moved and then held against gravity. Parkinson’s tremors classically occur at two characteristic times. Kinetic tremors occur for example, when the arm is moving toward the mouth to eat. Kinetic tremorĪ kinetic tremor occurs when a body part is moving.

Postural tremors occur for example, when the arms are extended, such as when holding a tray. Postural tremorĪ postural tremor occurs when a body part is held against gravity. Rest tremors occur for example, when the hands are resting in the lap, such as when watching television, or when the arms are dangling at the side when walking. Rest tremorĪ rest tremor occurs when a body part is not being held against gravity and is not moving. There are three main positions to consider. When deciding whether a tremor is consistent with a diagnosis of PD, the most important feature is the position of the body part in which the tremor occurs. action tremorĪ tremor is defined as movement of a body part that oscillates rhythmically around a midpoint. Today, we will discuss the features of various tremors, other medical conditions that can manifest with tremor, and the clues that distinguish a PD tremor from other types of tremor. However, there are many other medical conditions that can cause a tremor. Although about 25% of people with PD do not have tremor, 75% of them do, so tremor is certainly a very visible and characteristic symptom of PD. Many people think of Parkinson’s disease (PD) as the “tremor disease”, so much so, that when a tremor is noticed, the first diagnosis people typically think of is PD. A tremor doesn’t always mean it’s Parkinson’s
