How Does Alcohol Affect Essential Tremor? Alcohol & Essential Tremor ET

The two best-studied surgical treatments for severe limb tremor that hasn’t responded to medications are thalamotomy and deep brain stimulation (DBS). Both procedures can help reduce limb tremors; they are less useful for head shaking and a quavering voice. Parkinson’s disease is marked by a progressive loss of brain cells that produce dopamine, a chemical messenger that enables normal body movements. Essential tremor also appears to involve a disruption in the activity of motor pathways, but it’s uncertain whether there is any loss of brain cells.

Alcohol transiently improves the shakiness of patients with essential (familial) tremor. The possibility that essential tremor may lead to alcohol abuse and addiction is raised in relationship to three case reports. It is suggested that secondary alcoholism in patients with essential tremor may be treated or prevented by control of the essential tremor with beta-adrenergic blocking agents. Theoretical implications for the etiology of alcoholism are discussed. Hyperkinetic movement disorders with reported response to EtOH or GHB.

Deep brain stimulation

In its earlier stages, essential tremor is often minor and nothing more than an inconvenience or an annoyance. While essential tremor isn’t a dangerous condition, it can still keep you from taking care of yourself and living independently if the tremors become more severe. The possible complications and side effects of treatments for essential tremor depend on many factors, including the treatments themselves. Your healthcare provider is the best person to tell you what side effects or complications are possible in your specific situation, and what you can do to manage or avoid them. The appearance of your tremor, in the setting of a comprehensive neurological examination by an experienced clinician, can result in diagnosis of essential tremor.

Normally, the opening of HVA Ca2+ channels needs a large membrane depolarization, while a weak depolarization near the resting membrane potential could trigger the LVA Ca2+ channels, with IVA in between. Part of LVA Ca2+ channels stay inactivated under normal circumstances (70) (Figure 1). Ethanol is one of the activators of δ subunits of extra-synaptic GABAA receptors (66, 67). Tonic inhibition via extra-synaptic GABAA receptors is critical for long-term maintenance of the inhibitory status of neurons. Thus, ethanol might enhance tonic inhibition of target cells to compensate for dysfunction of postsynaptic or presynaptic GABAARs and thereby relieve symptoms in ERMDs (Figure 3).

Postsynaptic GABAARs are first considered as a candidate participant in the pathogenesis of essential tremor (ET). Not only α1 subunit-deficient mice manifest with similar postural and kinetic tremor to ET (61), but PET studies (62) and autoradiography experiments (63) also supported altered postsynaptic GABAAR functions among ET patients. However, the inconsistency in manifestations between α1−/− mice and ET patients casts doubt in this assumption. alcohol and essential tremor Specifically, tremor in α1−/− mice presents earlier in life and has a higher mean frequency (19.3 Hz), accompanied by considerable incoordination, which is not typical for ET patients (61). Besides, there is no report about any association between homozygous α1 subunit mutations and patients with ET or other ERMDs, shedding the possibility that loss-of-function of α1 subunits only share part of mechanisms with ET pathogenesis.

Although alcohol may cause or worsen several types of tremors, ET is slightly different. Some people with tremor, and people with other disorders, will find they are using alcohol to self-medicate and relieve symptoms. Regular usage to treat tremor can often lead to dependence and even alcoholism. In addition frequent drinking over a long period of time is known to worsen and cause depression and anxiety, and has been linked to diseases to the kidney and liver. Little data are available on the effects of LVA Ca2+ channel blockers on ERMDs. To date, among all the definite LVA Ca2+ channel blockers, only ethosuximide and zonisamide were reported to have effects on animal models (74, 106, 107), but little clinical efficacy was found in ethosuximide (108).

In this home video before and one hour after ingestion of six ounces of 80 proof vodka, significant improvement in myoclonus at rest and with action is evident. He did not tolerate Xyrem due to worsening depression, and he subsequently underwent bilateral DBS of the GPI, with surgical results pending at the time of this writing. First of all, ethanol is rapidly metabolized and eliminated in the human’s body and exhibits a tendency to produce a rebound of involuntary movements when it wears off (22). These characteristics make it nearly impossible for ethanol to serve as long-term control or modulation of the frequency of paroxysms. Furthermore, the ameliorative effects of ethanol may lead to alcoholism especially in those symptomatic patients. As reported in most cases, ethanol of small doses could achieve the best therapeutic effects on patients of ethanol-responsive movement disorders.

  • Besides, studies of diffusion tensor image (DTI) indicated the involvement of the superior cerebellar peduncle fiber tracts in ET patients, which receive input from the dentate nucleus and send output to the red nucleus (56).
  • Like EtOH, GHB reaches a peak dose within 35 minutes of administration, and plasma levels show a direct, non-linear dose response.
  • Animal models are also useful to interrogate the pathogenesis of the diseases.
  • But the samples don’t all show the same changes, so the import of these findings is uncertain.
  • He did not tolerate Xyrem due to worsening depression, and he subsequently underwent bilateral DBS of the GPI, with surgical results pending at the time of this writing.

However, to maintain the same treatment effects, repeated doses are necessary and dose of ethanol increases over time (18). Moreover, ethanol has various short-term and long-term adverse effects. With increasing frequency and rising doses due to tolerance, consumption of ethanol can cause irreversible damage to brains, livers, and other organs (93). Considering that some of ethanol-responsiveness diseases are characterized as early onset such as myoclonus dystonia, the damage once occurred may significantly affect patients’ quality of life and life span. Observed improvements with modest doses of EtOH or Xyrem are rapid, sometimes visible 15 minutes after the drug is administered, and always evident by 45–60 minutes. Response to treatment is typically dose-dependent, lasts three to four hours, and worsens the next morning with rebound in the case of EtOH.

Her quavering voice and trembling hands unmistakably betrayed the disorder. However, recent research suggests that essential tremor may be triggered by changes in certain areas of the brain, according to the National Institute of Neurological Disorders and Stroke (NINDS). Tremors can be caused by alcohol abuse, an overactive thyroid, or a stroke. They can also be caused by a variety of neurological conditions. A health care provider who still is not sure if a tremor is essential tremor or Parkinson’s disease might order a dopamine transporter scan. This scan can help the provider tell the difference between the two types of tremor.

Gamma-hyroxybutyric acid (GHB) is a derivative of GABA with similar effects to EtOH. GHB is found as an endogenous molecule within the brain, although at very low concentrations. Sodium oxybate (Xyrem), the sodium salt of GHB, has been studied as a potential treatment for refractory alcohol-responsive movement disorders. Like EtOH, GHB reaches a peak dose within 35 minutes of administration, and plasma levels show a direct, non-linear dose response. At higher doses the sedative effect peaks later (40 vs 60 minutes at a dose of 25 vs 35 mg/kg, respectively) and decays slower, reaching baseline in no more than 3 hours [20].
