Why Do My Hands Shake?
Known as familial tremor, benign essential tremor or hereditary tremor, Essential Tremor (ET) is a neurological condition that causes a rhythmic trembling of the hands, head, voice, legs or trunk. Some even feel an internal shake. ET is often confused with Parkinson’s disease although it’s eight times more common, affecting an estimated 10 million Americans and millions more worldwide. Because of stereotypes and a lack of awareness, many people with ET never seek medical care.
You are not alone. Some pretty well-know celebrities and politicians have been affected by ET: actress Katharine Hepburn, the late U.S. Senator Robert Byrd, John Adams (2nd U.S. President), John Q Adams (6th U.S. President), Jonathan Diefenbaker (13th Prime Minister of Canada), playwright Eugene O’Neill, and perhaps even General Douglas MacArthur.
ET an impact individuals both physically and psychologically. It can occur in people of any age, gender, or race and affects every day activities such as eating, drinking and writing. While the severity may vary from person to person, it often makes those affected self-conscious or anxious in social situations. While no cure has been found to date, medications and surgical treatments can help control tremor in many patients.
Essential Tremor – Medication Treatments
Medications Commonly Prescribed for ET:
- Propranolol (Inderal®) – Propranolol is the only medication approved by the Food and Drug Administration (FDA) for the treatment of ET and is available in immediate and long-acting formulations. Propranolol is a beta-blocker that is a drug used primarily for treating high blood pressure. Side effects of propranolol are usually mild and are more frequent at higher doses. The main side effects are decreased heart rate and blood pressure. Tell your doctor if you have heart failure, diabetes, or asthma. Patients who respond usually require a total daily dosage of 240 mg or less. Other beta-blockers such as atenolol, metoprolol, and nadolol can also be beneficial for treating ET.
- Primidone (Mysoline®) – Primidone is an anti-seizure medicine that can be effective in treating ET. Although it might have initial side effects such as nausea, poor balance, dizziness, fatigue, drowsiness, and flu-like symptoms, these side effects often resolve over time. To reduce the possibility of side effects, start with a small dose at bedtime (12.5 mg or one-quarter of one tablet) and gradually increase the dosage according to your doctor’s instructions.
- Clonazepam (Klonopin®), diazepam (Valium®), lorazepam (Ativan®), and alprazolam (Xanax®) – These anti-anxiety medications may be useful in patients who do not respond to other medications or who have associated anxiety. Side effects include sleepiness, dizziness, depression, fatigue, loss of coordination, memory loss, and confusion. These drugs are usually less effective than propranolol and primidone, and they can be addictive. There is also risk of withdrawal symptoms if the drugs are stopped suddenly.
- Topiramate (Topamax®) – Topiramate is an anticonvulsant that has been shown to be effective in controlling tremor in some patients. Side effects include numbness or tingling, memory loss, and weight loss.
- Gabapentin (Neurontin®) – Gabapentin is a generally well tolerated anticonvulsant, but controlled studies have produced conflicting results regarding its efficacy in ET. At best, this drug has a very modest benefit. It is tried by patients whose tremor is unmanageable by other medications. Side effects include fatigue, slurred speech, drowsiness, impaired balance, and nausea especially when beginning drug therapy.
Essential Tremor – Surgical Treatments
Essential tremor (ET) is one of the most common movement disorders, yet only about 50 percent of patients receive satisfactory benefit from the currently available medications. For patients with disabling tremor that is not adequately controlled by propranolol, primidone, or other medications, surgical treatments may be an option. Advances in the understanding of brain anatomy, more detailed imaging methods to better see the brain, and improved surgical techniques now allow for greater surgical accuracy and increased benefits with fewer complications than when surgical treatments were first introduced.
Current surgical options for ET include deep brain stimulation (DBS) and thalamotomy. Potential candidates for surgical procedures are ET patients who do not experience satisfactory tremor control with medications, and who have disabling tremor that affects their ability to perform activities of daily living such as eating, writing, drinking, dressing, working, or enjoying their hobbies.
