These results warrant future studies to investigate the safety and efficacy of OA at higher doses. Perhaps the biggest obstacle to our model is the question of how modest doses of EtOH or Xyrem exert their selective effect essential tremor alcohol on the cerebellum. Selective knock-down and optogenetic studies might allow investigation of this question, and high-resolution MRI and co-registered PET studies in patients and animal models would also be useful.

However, an effect of OA was measurable later than expected, and was more pronounced when tremor power of both hands were analyzed together, suggesting a systemic drug effect. Because a single time point was chosen as primary outcome to describe the peak effect of this low dose, future trials examining the therapeutic benefit in an outpatient setting should assess longer-term effects of OA. The weighted condition was used for analysis of tremor power of the central tremor component.
Tremor treatment
In 2020, almost 25 million people worldwide lived with essential tremor — a neurological disorder causing parts of the body to move or shake involuntarily. In Parkinson disease, tremor substantially lessens after thalamic, internal globus pallidus, or subthalamic nucleus deep brain stimulation. Levodopa Levodopa Parkinson disease is a slowly progressive, degenerative disorder characterized by resting tremor, stiffness (rigidity), slow and decreased movement (bradykinesia), and eventually gait and/or…
EtOH increases inhibitory output from the cerebellum to the ION (and thus increased blood flow in this area); consequently, ION stimulation is reduced and tremor is suppressed [17]. Consistent with this idea, EtOH has also been reported to be a decoupling agent, able to inactivate gap junctions that are normally found in synaptic clefts and are particularly represented in the ION [18]. Many patients with essential tremor (ET) report transient improvement of symptoms after drinking alcohol. However, the brief duration of action, subsequent rebound, and the risk of developing alcohol addiction make the use of alcohol as a treatment for ET inappropriate.
Classification of evidence.
In a series of three papers, Volkow and colleagues investigated the effect of a modest dose of EtOH in normal individuals, employing doses that were not intoxicating or sedating. In both women and men, a single low dose of EtOH produced the greatest metabolic reduction in the cerebellum, with no change in thalamic metabolism and a mild increased metabolism in striatum [58]. A second study https://ecosoberhouse.com/ using increasing modest doses of alcohol [59] again showed the largest metabolic reductions in the cerebellum as well as thalamus and mesencephalon. The final study with co-registered MRI localization confirmed this effect on the cerebellum and occipital cortex [60]. These three papers illustrate that modest doses of EtOH selectively and preferentially reduce cerebellar metabolism.
- Total tremor power in the spectral peak was calculated and averaged across epochs using self-developed Matlab® Scripts.
- A second study using increasing modest doses of alcohol [59] again showed the largest metabolic reductions in the cerebellum as well as thalamus and mesencephalon.
- Despite treatment with clonazepam, valproic acid, phenobarbital, topiramate, zonisamide and levetiracetam, paroxysms of myoclonus affecting the trunk, head and limbs, are triggered by any attempt to move.
