Determine the prevalence of Cognitive Impairment among Essential Tremor (ET) patients.
Essential tremor (ET) is among the most prevalent neurological diseases (1). Could be presented in 4% of adults after 40 years old. The clinic impact that generates cognitive impairment associated to ET is still unknown (2). According to Aguilar-Navarro et al. (2017)  the cut-off point for the Montreal Cognitive Assessment (MoCA) in mexican population is ( Mild Cognitive Impairment = < 26 and for Dementia = <24 points).
We performed a descriptive cross-sectional study. Demographic data was collected from random ET patients who came to our Institute for regular consult using a questionnaire. MoCA and Fahn-Tolosa-Marin tremor rating scale were used.
We included 20 ET patients with  mean age of 66 ± 10.013, 14(70%) women and 6 (30%) men. The sample was stratified in 3 groups: 0= No cognitive impairment, 1= Mild cognitive impairment, 2=Dementia. Demographic statistics are shown in table 1. There was no relevance association between Fahn-Tolosa-Marin tremor rating scale and MoCA. Prevalence of cognitive impairment (table 2) according to the mexican cut-off point for MoCA.
MoCA it’s a reliable, valid and precise tool to evaluate cognitive impairment in ET patients in mexican population. However, it’s needed to use further studies and a larger sample to confirm the high prevalence of dementia in ET patients.
