“…There is a growing belief that isolated head tremor and other focal or task-specific tremors are dystonia [14••]. Consequently, both the TRIG and the MDS Consensus criteria for classic ET exclude isolated position-specific or task-specific tremors (eg, occupational tremors, primary writing tremor) and isolated tremor in the voice [44], tongue, and chin [45] or legs [34••, 46]. …”

Classic essential tremor is a clinical syndrome of action tremor in the upper limbs (at least 95% of patients) and less commonly the head, face/jaw, voice, tongue, trunk, and lower limbs, in the absence of other neurologic signs. However, the longstanding notion of that essential tremor is a monosymptomatic tremor disorder is being challenged by a growing literature describing associated disturbances of tandem walking, personality, mood, hearing and cognition. There is also epidemiologic, pathologic and genetic evidence that essential tremor is pathophysiologically heterogeneous. Misdiagnosis of essential tremor is common because clinicians frequently overlook other neurologic signs and because action tremor in the hands is caused by many conditions, including dystonia, Parkinson disease and drug-induced tremor. Thus, essential tremor is nothing more than a syndrome of idiopathic tremulousness, and the challenge for researchers and clinicians is to find specific etiologies of this syndrome.

“…3,4 Essential tremor is one of the most common movement disorders, affecting approximately 4-5.6% of people over the age of 40 years. 5 Essential tremor is characterized by a postural and action tremor with a frequency of 4-12 Hz that typically involves the upper extremities.…”

“…Previous studies have shown 5% to 20% and 32.3% to 93% prevalence of coprevalent movement disorders at presentation in patients with ADSD and vocal tremor. In the present study, patients with ADSD were found to have significantly fewer concomitant movement disorders (11.5%) compared to patients with ADSD + LT (38.7%) or LT (57.1%).…”

Objective To compare presenting characteristics of patients with adductor spasmodic dysphonia (ADSD), ADSD with laryngeal tremor (ADSD + LT), and laryngeal tremor without ADSD (LT) Design Cross-sectional analysis Methods Patients treated for laryngeal movement disorders (1990–2016) were included. ANOVA and Chi square tests measured differences in patient characteristics across the three disease groups. Using ADSD as the referent, multivariable logistic regression models were used to determine whether potential risk factors including patient demographics, family history, presence of potential inciting events prior to disease onset, and co-prevalent movement disorders were associated with ADSD+LT or LT. Results In all, 652 patients with ADSD (n=377), ADSD + LT (n=98), and LT (n=177) were included. ADSD patients were significantly younger than those with ADSD + LT and LT (52.5±13.4, 63.9±11.3, and 69.3±10.5 years, respectively; p<0.001). Co-prevalent movement disorders were more common in ADSD + LT (38.7%) and LT (57.1%) groups than in the ADSD group (11.5%; p<0.001). Compared to ADSD, patients with ADSD + LT and LT were more likely to develop an additional movement disorder during follow-up. In multivariable analyses, increasing age, female gender, and having a movement disorder at presentation were associated with significantly greater odds of having ADSD + LT or LT when compared to ADSD. Conclusion ADSD + LT patients demonstrate intermediate gender composition and age distributions between those with ADSD and LT. These findings suggest that ADSD + LT may be a distinct phenotype in the spectrum of laryngeal movement disorders.
