Essential Tremor

Essential tremor is a neurological condition of the nervous system that results in rhythmic and involuntary shaking. An individual's hands tremble the most frequently, especially when performing even the simplest of things, such as sipping from a glass or tying shoelaces. It is well to note that this condition can practically affect any part of the body.

The good thing is that, in most cases, essential tremor may not be harmful, but in some scenarios, it can get worse with time. This condition is often mistaken for Parkinson’s disease. Other diseases, in fact, do not cause its occurrence. Notably, essential tremor is prevalent in individuals who are 40 and older.

The symptoms of this condition are gradual and are usually more prominent on one side of the body. That said, the condition gets worse with movement. It is often seen that the tremor occurs in the area of the hand first, affecting either one hand or even both. It gets more aggravated by fatigue, emotional stress, or even caffeine or extreme temperatures.

The essential tremor condition is frequently associated with Parkinson's disease. However, both differ in many ways. Essential tremor of the hands occurs when the hands are used, whereas Parkinson's disease tremors usually occur when the hands are at the sides or resting on the lap.

One of the significant differences between essential tremor and Parkinson’s disease is that the former usually does not cause any other health issues, while the latter may result in slow movement, feet being dragged when walking, and even a stooped posture.

Essential tremors are generally found around hands, head, and voice whereas Parkinson’s disease tremors begin with the hands and then can affect the legs, chin, and other parts of the body.

Dr. Abhijit Kumar Kohat remarks that a dopamine transporter scan can be suggested in case it is unclear if the tremor is caused by Parkinson’s disease or essential tremor.
