Essential Tremors Causes
The exact cause of benign essential tremor is still not indentified, but it is thought that the abnormal electrical brain activity that causes benign essential tremor is processed through the thalamus. The thalamus is a constitution deep in the brain that coordinates and controls muscle activity.
Genetics is responsible for causing ET in half of all people with the condition. A child born to a parent with benign essential tremor will have up to a 50% chance of inheriting the responsible gene, but may never really experience symptoms. Although ET is more general in the elderly and symptoms become more pronounced with age it is not a part of the natural aging process.
There is no cure for essential tremor. Treatment for Benign Essential Tremor aims to suppress the involuntary movements, and can include:
- Stress management method
- Avoidance of known triggers, such as alcohol or caffeine
- Some drugs used to treat other medical conditions, such as heart disease and epilepsy. These drugs have been successful in some cases
- Other drugs, including tranquillisers
- Deep brain stimulation, a surgically implanted device that helps to short-circuit the impulses or brain waves causing the tremor
- Brain surgery to alter the part of the brain causing the tremor has been helpful in some cases
- Regular monitoring and observation – if the tremor is mild and does not stop the person from performing their usual activities, this may be the only treatment.
In some cases, alcohol may diminish the tremors. But, this is not a suggested treatment, because long-term consumption of alcohol has significant health risks.
