Hand tremors are a common symptom, and many people are concerned about whether they are suffering from Parkinson’s disease after they find out that their hands are shaking. However, there are many reasons why hand tremors occur, and they may be caused by physiological, psychological or disease factors. To understand the cause of hand tremor, we can start with the tremor pattern.

Tremor Patterns

Tremor can be divided into Resting Tremor and Action Tremor, which occurs when the muscles contract. Most tremors are action tremors, which can be subdivided into postural tremor, isometric tremor, kinetic tremor, and intention tremor.

Common causes of tremor

Physiological tremor

The most common cause of motor tremor is physiological tremor, which is usually not easily detected. It may be caused by taking drugs that cause sympathetic stimulation, caffeine, nicotine, and other chemical stimuli.

Essential tremor (ET)

It is the most common form of pathological tremor and is mainly related to genetic predisposition and age. In addition, most patients older than 40 years of age are classified as having benign tremors, but severe cases can cause social impairment and even inability to work. Patients may report having tremors in early adulthood, and although the condition may get progressively worse, they often do not seek medical attention until several years have passed.

Parkinsonian tremor (tremors)

However, as the disease continues to progress, patients will gradually develop tremors, stiffness, slowness of movement, body coordination, small steps, micrographia, masked face, and other problems, including sleep disturbances, depression, easy fatigue, and memory problems. The prevalence of Parkinson’s disease increases with age and usually occurs after the age of 60.

Different stages and symptoms of Parkinson’s disease.

Some of the more typical Parkinson’s syndrome tremors begin with a low-frequency, pill-rolling movement of the fingers. begins again as soon as one relaxes. Resting tremor is one of the most important conditions for the diagnosis of Parkinson’s disease.

The common causes of tremors, types of tremors, tests and treatment options are summarized.

Tremor is an outward sign of the disease, so beware of subsequent conditions

In Parkinson’s disease, for example, although tremors are initially a symptom of the disease, as the disease progresses, there may be difficulties in inspiring movements, abnormal walking postures, and the possibility of being unable to brake or stop in the middle of walking.
