“…1,2 In addition to action tremor and other motor features, recent studies report nonmotor features. [3][4][5] In a growing number of studies, mild cognitive problems are being observed in ET cases. [6][7][8] Furthermore, an association between ET and dementia was reported in a recent population-based study in central Spain.…”

“…ET predominantly involves hands and may also spread to head, vocal cords, lips, and rarely to lower extremities [12,13]. Recently, it has been reported that hearing is impaired in patients with ET [4,6].…”

“…Studies have indicated that mild cognitive impairment, personality changes, and olfactory nerve dysfunction may be associated with ET [2,3]. Recent studies have also demonstrated an association between ET and hearing impairment [4][5][6]. Ondo et al [4] also found that ET patients had an increased hearing disability compared to patients with Parkinson's disease (PD) and normal controls.…”

“…Ondo et al [4] also found that ET patients had an increased hearing disability compared to patients with Parkinson's disease (PD) and normal controls. Benito-Leon et al [6] conducted an epidemiological study on people aged between 25 to 55 with ET to examine the hearing loss in this population. Researchers found that 96 (38.7%) of 248 ET cases reported hearing loss versus 1,371 (29.4%) of 4,669 controls.…”

The aim of this study was to investigate audio-vestibular function in patients with essential tremor. Twenty-three patients with essential tremor (46 ears) and 21 health control subjects (42 ears) were included in the present study. Patients and comparison subjects were matched for age and gender. All patient and control subjects underwent pure tone audiometric test, tympanogram, transient-evoked otoacoustic emissions and auditory brainstem response. Vestibular system was evaluated by bitermal caloric test. Comparison of variables between the groups was performed. Investigation of the relationship between parameters about ET disease and hearing levels were also studied. Pure tone thresholds significantly differed between patients and controls in 250 and 500 Hz frequencies (p < 0.05). There was no statistically significant difference in 1,000, 2,000, 4,000, and 6,000 Hz frequencies in essential tremor patients in comparison to the control subjects. A correlation between tremor severity and audiometric scores in low frequencies was not found. In addition, statistical analysis did not demonstrate a correlation between audiometric scores and tremor duration. The otoacoustic emission responses were found significantly different in patient and control group. The latencies of waves I, V and I-V inter-peak latencies on the ABR were not different between the groups. Our findings indicated that, abnormalities are due to cochlea rather than the retro cochlear pathology which is responsible for hearing loss associated with essential tremor.

“…The emerging evidence of recent years has changed the classical view of ET as a monosymptomatic condition, characterized by a kinetic arm tremor, to include a mixture of previously unrecognized motor and nonmotor problems [9,15,16,17,18]. Several studies have been performed comparing functional neuroimaging in ET and PD patients, and suggest that, as ET progresses, dysfunction in the nigrostriatal system may become more apparent and may contribute to parkinsonian symptoms of neurodegeneration [19].…”

Quantitative Analysis of Reduced Arm Swing Frequency in Essential Tremor

et al. 2010

Background: Essential tremor (ET) has recently been accepted as a heterogeneous disorder which may be associated with synuclein pathology or a variety of other genetic disorders. Methods: We observed decreased arm swing frequency in 18 of 136 definite ET patients, and recorded the associated arm movements in 18 ET patients and 33 sex- and age-matched healthy controls. Results: The mean frequency of the right arm (p = 0.047), left arm (p = 0.025) and leg (p = 0.030), and the mean arm/leg frequency on the right side (p = 0.048) were significantly lower in ET patients. The mean frequencies for both arms and legs were significantly lower for the more affected side of the body (p = 0.034 and p = 0.036, respectively). Conclusion: We conclude that ET may be associated with decreased arm and leg swing frequencies, especially on the more affected side of the body.
