Clinical Profile in Patients With Essential Tremors

Not yet recruiting

• Conditions: Essential Tremor

• Registration Number: NCT05170022
• Lead Sponsor: Assiut University

Brief Summary

Essential tremors are no longer a single motor disorder but disorder of movement associated with non-motor symptoms and the aim of this study is to explore the clinical profile of patients with essential tremors including motor and non-motor features and their relationship.

and to identify clinical predictors of these features.

Detailed Description

Essential tremors (ET) was defined as mono-symptomatic tremor syndrome involving both upper limbs during action for at least 3 years, with or without tremor in other body parts . ET is considered the most prevalent adult movement disorder, The crude prevalence of ET varies widely from 0.08 to 220 cases per 1000 persons. Many pathological post-Mortem studies are providing evidence that ET is mostly can be recognizes as neurodegenerative disease of the cerebellum and brain stem .

In the last decade there is an emerging studies that discuss the presence of associated motor, non- motor, sensory and psychological symptoms besides the tremors . Motor features of ET are not confined to tremors. Another feature of ET is gait ataxia , Eye movement abnormalities of subclinical degree, difficulties in learning motor skills, Bradykinesia and slowness of finger tapping .

Studies of the last two decades reported mild cognitive deficits in patients with ET in comparison to healthy controls. These deficits affect number of cognitive domains, especially verbal memory, naming, verbal fluency, attention- concentration, working memory and concept formation . In addition ET was found to be associated with hearing impairment with abnormal threshold at higher tone frequencies which refer to sensorineural hearing loss, and olfactory deficits which both may points to cochlear pathology. Moreover, patients with ET thought to have higher incidence of depression and anxiety symptoms than age-matched healthy individuals correlated with tremors severity .
