Abstract
Objective: Essential tremor is the most common movement disorder diagnosed during adolescence. However, there are insufficient data about its prevalence among adolescents. This study
aims to determine the prevalence of potential essential tremor cases in Turkish adolescents.
Materials and Methods: This cross-sectional study was carried out in Istanbul, Turkey. A total
of 5 high schools were visited. In the first step, the authors provided 5559 students (aged 14-18)
with clinical information about tremors and essential tremors in their classrooms. After that,
a 12-item questionnaire filled by adolescents and parental consent forms were collected. The
response rate was 78% (n = 4330). According to the questionnaire answers, adolescents who
complained of experiencing tremors in any part of their body were clinically evaluated in the
second step of the study. Lastly, a neurological examination to classify essential tremors based
on the Washington Heights Inwood Genetic Study of Essential Tremor (1998) diagnostic criteria
was conducted by a specialist.
Results: The prevalence of tremor in the respondents aged 14-18 (median = 15) years was 1.2 %
(n = 52/4330), and the prevalence of essential tremor was 0.41% (n = 18/4330). Male to female
ratio for essential tremor was 5 : 1 (male = 15 and female = 1). Essential tremor cases were subclassified as following: 10 (55.5%) definite essential tremor, 3 (16.6%) probable essential tremor,
and 5 (27.7%) possible essential tremor.
Conclusion: The data support the claim that essential tremor is a prevalent movement disorder
in Turkish adolescents.
