    Eligibility Criteria

    Sex: All
    Minimum Age: 50
    Maximum Age: 75
    Age Groups: Adult / Older Adult
    Healthy Volunteers: Yes

    Inclusion Criteria:

    * Diagnosis of moderate or severe classic essential tremor (bilateral, largely symmetric postural or kinetic tremor involving hands and forearms.
    * Willingness to abstain from ethanol and caffeine intake for at least 48 hours prior to Days 1 and 4 and on inpatient days

    Exclusion Criteria:

    * Subjects with a clinically significant unstable medical abnormality, chronic disease or history or presence of significant hepatic, renal, endocrine, cardiovascular, gastrointestinal, pulmonary, psychiatric, or metabolic disease or any other abnormality
    * Subjects who are on sodium-restricted diets
    * Subjects with a known history of sleep apnea

    Primary Outcomes
    • The modified FTM sum of all essential rating tremor scales including voice tremor includes: the tremor rating taken for the left \& right hands individually at rest, with posture (arms outstretched), with action (finger to nose). It also includes an evaluation of voice with scores for AAA \& EEE sounds, an action evaluation of left \& right hands pouring, bringing liquids to mouth, drawing large \& small spirals. Scores for indiviuals items range from 0 (no tremor) to 4 (severe tremor). The sum ranges from 0 (no tremor) to 72 points (higher amplitude/more tremors).
