Tremor

Essential Tremor A tremor is trembling or shaking that you cannot control. Most tremors affect the hands or arms. Tremors can also affect the head, vocal cords, face, and other parts of the body. Essential tremor is a tremor without a known cause. CAUSES An essential tremor has no known cause. RISK FACTORS You may be at greater risk of essential tremor if: • You have a family member with essential tremor. • You are age 40 years or older. • You take certain medicines. SIGNS AND SYMPTOMS The main sign of a tremor is uncontrolled and unintentional rhythmic shaking of a body part. As a result, you may have: • Difficulty eating with a spoon or fork. • Difficulty writing. • Nodding your head up and down or side to…

Postural Tremor As stated above, postural tremor occurs when the limb is placed in a fixed position against gravity, and may continue or increase during movement. Postural tremor is subdivided into physiologic tremor, ET, alcohol or drug withdrawal, metabolic disturbance, drug-induce tremor, and psychogenic tremor. Each subtype of tremor is discussed in the paragraphs below. Physiologic tremor. Physiologic tremor exists in all mankind including people who are healthy; however, it is typically…

More than fifty percent of essential tremor cases, also known as familial tremor are caused by genetics. It’s an autosomal dominant disorder, needing only one parent to pass the mutated gene on to the offspring. Sometimes the child is only a carrier with no sign of the condition. Instances where both parents are carriers of the inherited gene raise the risk of a child developing essential tremor. Age is another factor causing this second most common movement disorder. Electrical fluctuations in…

Associated With Tremor Beyond occupational risk factors associated with tremor, research indicates several non-occupational factors are also associated with increased risk for tremor. Some of these factors include gender, age, alcohol, use of tobacco, and emotional stress. Each of these factors is explored in the paragraphs below. Gender According to several studies, most women affected with ET have their head and voice more significantly affected than any other parts of the body. On the…

As we know, Parkinson 's disease is a globally occurring mental defect that affects human 's central nervous system. Currently, there is no cure for the disease, and we can 't even diagnose the cause of this disease. DBS is still a developing technology being widely employed to fix neuropsychiatric disorders. It is a surgical therapy employed to curb this deadly disorder as well as essential tremor. The method involves the patients undergoing surgery. This surgery uses some high technology to…

Mother nature, the giver of life, a force of nature that controls the balance of power keeping everything in order and at peace. Even thought she is keeping caring and graceful but, she has a dark side she must maintain the balance of power. There for there is no escape for the gazelle from that final bit from the mouths of their predators, the lion. To survival in nature is all about survival of the fittest, an example of this comes from on of my favorite movies Tremors 5 Bloodlines “ Every…

Head Shakes and Dystonia Many people with dystonia experience head shake especially if the dystonia is affecting their neck. People often ask us about the difference between head shaking caused by essential tremor and that caused by dystonia. In this article Prof Karim explains what the differences are and how to tell if it is dystonia or not. A majority of the world’s population at some point use their head and neck muscles in order to carry or transport heavy goods. To do this, the control of…

The area under the surface of the earth where the earthquake takes place is called the hypocenter, and the area above this place is called the epicenter. In some cases a seismic tremor has foreshocks. These are littler quakes that happen in the same place as the bigger tremor that takes after. Researchers can 't tell that a seismic tremor is a foreshock until the bigger quake happens. (USGS, pg 3). The biggest, principle quake is known as the mainshock. Mainshocks dependably have consequential…

Parkinson’s disease (PD) was first described by James Parkinson in his classic 1817 monograph “Essay on the Shaking Palsy”. PD is the second most prevalent neurodegenerative disorder after Alzheimer’s disease (AD). PD affects around 0.3% of population in industrialized countries and approximately 1% of the population above the age of 60 (de Rijk et al., 2000; Rajput, 1992). The mean age of onset of PD is 55. PD is mainly characterized clinically by resting tremor, rigidity and bradykinesia.…

Throughout my research I had a multitude of inquiries on how prosthetics could be used to expand the body. As I mentioned before, prosthetics move from identifying nerve signals being sent from the brain, as well as from contractions, but I wonder if they can just use contractions to make an entirely new limb that can be controlled by just by contracting certain muscles, as an external prosthetic. It could be an extra arm or leg, or even finger, and even if it wouldn’t be fully controlled, it…
