Motor data (TETRAS performance, digital spirals) were normalized using the ratio of 60 min to baseline. Thus, a score of 1 indicates no change from baseline and values toward 0 represent a decrease from baseline. Nonmotor data (BAES, DEQ, AUQ) were normalized as a raw change from baseline. Patients taking medications known to interact with ethanol or affect brain excitability (e.g., hypnotic, antiepileptic, antipsychotic medication, stimulants, antihistamines, and muscle relaxants), as well as female patients tremor improves with alcohol who were pregnant or lactating, were also excluded. A metabolic panel for liver function was administered, and patients with abnormal liver function parameters were excluded.

Health Challenges

We present video examples of robust responses to EtOH or Xyrem in thirteen selected patients treated by the senior author in IRB-approved clinical trials or clinical practice over the last fifteen years. We specifically selected video segments that illustrated a robust response. Patient #1, a 37-year-old woman, underwent a routine gynecological surgery complicated by an unrecognized esophageal intubation leading to refractory severe PHM 47. 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. Twenty minutes after ingesting two eight-ounce glasses of wine in the office, her myoclonus improved for the first time in three and a half years, enough for her to gesture fluidly (telling her husband to “shut up”). She was even able to walk with only mild support from her home aide while the EtOH effect lasted.

Alcohol responsiveness

• Before the 1990s, the main surgical intervention for essential tremor was thalamic lesioning.
• Professor Nancy Ip discusses her groundbreaking neuroscience research, focusing on neurotrophic factors and innovative Alzheimer’s disease treatment approaches.
• In this exploratory analysis, differences of OA compared with placebo within subjects showed a significant benefit of OA across time.
• If you have ET, you likely have been diagnosed with a tremor that has shown up without any known cause.
• The first step in treating alcohol tremors is addressing the underlying issue, which is alcohol withdrawal.
• Since January 2019, and after conclusion of this study, Dr. Haubenberger is a full‐time employee of Neurocrine Biosciences, Inc. (San Diego CA).

Despite treatment with valproic acid, levetiracetam and zolpidem, severe action and intention myoclonus were disabling. He was admitted to hospital in order to titrate increasing doses of Xyrem in an observed setting (he did not receive an EtOh challenge as he was only 19 years old). One hour after administration of 1.5 gm of Xyrem, action and intention myoclonus were reduced, allowing him to perform tasks such as brushing his hair for the first time. He has remained on Xyrem for the last three years with clear awareness of kinetics of the drug, and no evidence of tachyphylaxis 51; bilateral DBS of the GPi was performed two years after this video was taken, with additional functional benefit.

ACTIONS

Alcohol tremors can also indicate a more severe form of alcohol withdrawal, called delirium tremens (DT’s). Delirium tremens is mainly characterized by tremors, hallucinations, disorientation, confusion, and increased heart rate/breathing rate/blood pressure. Delirium tremens is a much more serious form of alcohol tremors and usually appears a couple of days after someone ends an intense drinking binge. DT’s are especially common if you do not eat enough during your drinking binge or have a long history of alcoholism.

This time point was chosen based on pharmacokinetic data on OA from previous studies of 1-octanol, expecting a peak effect 80 minutes after administration. Secondary efficacy outcomes included nondominant hand postural and spiral tremor intensities. Furthermore, all other time points were analyzed for the central tremor component and the total tremor. Pharmacokinetic analysis of OA plasma concentration across time points as well as the safety assessment were performed as secondary outcome measure. In an open label prospective trial, 37 patients received olanzapine, most taking mg daily in divided doses.140 Tremor significantly improved, and the effect was maintained over six months. Almost 40% of patients taking olanzapine reported that their tremor completely disappeared, and around 58% had a slight/barely noticeable tremor.

At each time point, tremor and EMG were recorded simultaneously for 2 minutes, before and after placement of a 1-lb weight attached to each hand. The continuous files were broken into 8,192-millisecond epochs at a sampling rate of 1,000 Hz. Total tremor power in the spectral peak was calculated and averaged across epochs using self-developed Matlab® Scripts.

Treatment

There was also a significant difference in BSTIM change score for the responders (5 0 to 12), but not for the nonresponders (5 −1 to 11). For the Drug Effects Questionnaire (DEQ), there was a significant difference in change score for both responders (120 63.8–183) and nonresponders (149 52.4–242). Despite these within‐group changes, there were no significant differences between responders and nonresponders for the BSTIM, BSED, DEQ, or Alcohol Urge Questionnaire (AUQ; Table 2).
