Prevalence of Essential Tremor

Prevalence of and Annual Conversion Rates to Mild Cognitive Impairment and Dementia: Prospective, Longitudinal Study of an Essential Tremor Cohort

“…Hence, the absence of biomarkers and neuroimaging data has restricted our ability to specifically identify Alzheimer disease or other distinct forms of dementia in our cohort. Finally, there is some evidence that the population prevalence of ET is higher in Whites than in African Americans, and that it is intermediate in Hispanics 57,58 ; however, the homogeneity of the current COGNET cohort likely reflects the multiple barriers that have historically reduced participation by individuals from ethnoracial minority groups in studies involving brain donation. Future work should adults from under‐represented ethnoracial backgrounds including non‐Hispanic Black and Hispanic.…”

Neuroimaging Assessment of Nigrosome 1 with a Multiecho Gre Magnetic Resonance Sequence in the Differentiation Between Parkinson’s Disease from Essential Tremor and Healthy Individuals

“…The sensitivity, specificity, positive predictive value and negative predictive value for the absence of nigrosome1 were calculated for each evaluator, followed by a combined evaluation. For the sample size calculation, we used the described prevalence of 1680/100.000 to TE [ 18 ] (n = 11, power of 88,45%), 1250/100.000 to PD [ 19 ] (n = 38, power of 86,13%) and the formula N = Z 2 *[P *(1-P)]/D 2 (OPS,1997) [ 20 ].…”

How Common is Essential Tremor? Update on the Worldwide Prevalence of Essential Tremor

“…That study used on a screening questionnaire, however, which may have biased results toward lower prevalence among individuals with lower educational attainment [33]. Similarly, a study in northern Manhattan, USA, reported a nonsignificant trend in which the prevalence was higher in whites than African-Americans; that study similarly relied on an initial screening questionnaire [13].…”

“…A study in Singapore compared the prevalence of ET in Singaporean Chinese, Malays, and Indians, and reported a marginally higher prevalence in Indians compared to Chinese; no Malays were identified with ET. A study in Copiah county, Mississippi, USA reported a nonsignificant trend in which the prevalence of ET was higher in whites than African-Americans [33].…”
