Essential tremor is a neurological or nervous system disorder that causes involuntary and rhythmic shaking. It can affect almost any part of the body but shaking or trembling most often occurs in the hands. It also affects other body parts like legs, voice, head, etc. It affects simple tasks like writing, tying shoelaces, drinking, etc.
The exact reason behind essential tremors is unknown. Some of them can be
A few signs and symptoms of essential tremor are:
Treatment is unnecessary for everyone with essential tremors, especially if the symptoms are minor. However, some possible Essential Tremor treatments can lower the symptoms.
A few of the most common risk factors for essential tremors are
Essential tremors do not cause any other problems. It does not spread to internal organs. It only affects neuronal cells in certain parts of the nervous system. The damage to those areas can progress. As the condition progress, the severity of symptoms may become worse. Some other symptoms, like problems with posture, gait, etc., can appear as the condition progresses. However, it is not a life-threatening condition.
A few of the things we can do to either lower the intensity of the tremors and not worsen the condition are
It is also known as the familial tremor.
Essential tremors are often mistaken for another condition called Parkinson's disease. This condition is also a nervous system disorder, and it also presents with involuntary tremors or movements that are similar to essential tremors. However, there is an underlying cause for Parkinson's disease. Essential tremors, on the other side, do not have particular underlying conditions or symptoms. These are entirely different disorders.
The doctors make the diagnosis of essential tremors by ruling out other conditions. A physical examination is performed to check for reflexes, posture, muscle strength, tone, etc. Other tests or exams like CT or MRI are not necessary to rule out any underlying cause such as a tumor. It is essential to inform your family history and symptoms to the doctor.
Essential tremors are more prevalent than other conditions like Parkinson's disease. It usually occurs in around 3 to 4 per every 1000 people. It is more common as age advances, although it has been seen in children. Family history is most common in the younger population with essential tremors. Gender has not been relevant for this condition.
Even though essential tremor is not a life-threatening condition, it can make daily tasks harder to perform. It affects the person's ability to perform specific tasks or activities of daily life. The frequency of tremors may decrease as the person ages, but the severity increases.
Most commonly, tremors affecting the hands or arms can progress slowly compared to other areas like the head or voice. It is a generally progressive disorder. But the rate at which it progresses is slow on average. Some studies have concluded that the average rate of progression is approximately 1.5 to 5% every year.
In essential tremor, certain parts of the brain and nervous system degenerate and causes dysfunction. It leads to the degeneration of neurons in those regions. Degeneration happens when specific receptors in the brain do not work correctly and do not provide the required stimulation. It results in the misfiring of nerve cells, causing tremors.
