octanoic acid and Essential Tremor

octanoic acid has been researched along with Essential Tremor in 7 studies

octanoic acid: RN given refers to parent cpd; structure in Merck Index, 9th ed, #1764
octanoic acid : A straight-chain saturated fatty acid that is heptane in which one of the hydrogens of a terminal methyl group has been replaced by a carboxy group. Octanoic acid is also known as caprylic acid.

Essential Tremor: A relatively common disorder characterized by a fairly specific pattern of tremors which are most prominent in the upper extremities and neck, inducing titubations of the head. The tremor is usually mild, but when severe may be disabling. An autosomal dominant pattern of inheritance may occur in some families (i.e., familial tremor). (Mov Disord 1988;13(1):5-10)

Trial Outcomes

Auditory-perceptual Tremor Severity Ratings

Three experienced listeners independently rated each participant's voice from paired sample recordings comparing the baseline to post-test samples in randomized order for each condition. Sustained vowel and sentence-level recordings were rated, with decoded samples later analyzed for 1=better for post-test compared to baseline, 0= no difference between post-test and baseline. Maximum score for each participant was 3 (post-test was better for each of three raters). The range of possible scores was the sum of each of three raters' scores (0 to 3), with 0 indicating no difference between baseline and post-test voice tremor severity rating, and 3 indicating better voice (less tremor severity) at post-testing compared to pre-testing. Mean post-test values for task were compared for the octanoic acid and placebo conditions, and all raters were blind to which sample was a baseline versus a post-test recording, and which samples were associated with the [placebo or octanoic acid conditions. (NCT01864525)
Timeframe: Measured at baseline visits (1 & 2) and after 3 weeks of placebo or octanoic acid on post-test visits (1 & 2).

Magnitude of Acoustic Amplitude Tremor and Magnitude of Acoustic Frequency Tremor

Voice recordings were used to measure the degree of tremor in the voice. Mean post-test values for each acoustic measure were compared after the octanoic acid and placebo conditions, with and without consideration of baseline values. Mean values represent the average of two testing days. Degree of amplitude tremor shows the extent of amplitude variation as a percent of the mean signal amplitude, with lower numbers indicating less amplitude tremor. Baseline values for magnitude of amplitude tremor across all participants and conditions ranged from 4.06 to 27.09, and post-test values ranged from 1.94 to 26.02. Degree of frequency tremor shows the extent of fundamental frequency variation as a percent of the mean signal frequency, with lower numbers indicating less frequency tremor. Baseline values for magnitude of frequency tremor across all participants and conditions ranged from 1.21 to 15.31, and post-test values ranged from 0.60 to 13.86. (NCT01864525)

Normalized Mean Tremor Amplitude for Both Formulations of 64 mg/kg 1-Octanol in Part B

Spirography mean tremor amplitudes were measured in the right hand of each participant at 0, 15, 30, 60, 90, 120, 150, 180, 240 and 360 minutes post-dose. Then, the scores of each participant were normalized (i.e., divided by) by their baseline tremor severity scores so that all scores are expressed as a proportion of the baseline score. Therefore, 1 is the baseline tremor severity, and lower scores indicate tremor reduction. (NCT00102596)
