Cognitive Assessment in Patients with Essential Tremor: A Prospective Study
Journal Title: INTERNATIONAL JOURNAL OF SCIENTIFIC STUDY - Year 2017, Vol 5, Issue 2
Abstract
Introduction: Tremor is a rhythmic, oscillatory movement produced by alternating or synchronous contractions of antagonist muscles. Essential tremor (ET) is neurodegenerative disease it is clinically progressive disorder because of frontal and temporal lobe involvement of brain. ET is commonly associated with cognition impairment. Aim: This is the study to analyze the cognition impairment in ET patients. Methods: ET patients were analyzed by tremor rating scale and their cognitive assessment was done by neuropsychological test, mini-mental state examination, Addenbrooke’s cognitive scale, Alzheimer’s disease assessment scale-cog scale, and frontal assessment battery test. Results: A total of patients included in this study were 50. Out of these, 31 were male and 19 were female. There was a signifi cant family history in 21 patients (42%). Tremor frequency was 5-10 Hz in 80% of patients. Nearly 20% of patient had frequency more than 10 Hz. Conclusion: Finding that the subclinical cognitive defi cits characterized by attention and verbal memory impairments and executive dysfunction is a clinical feature of ETs.
