Essential tremor (ET) is a progressive neurological disease associated with functional disability, diminished quality of life and, in some individuals, poorer balance, cognitive impairment, depression and sleep dysregulation. Individuals with ET may rely on family members and friends to act as informal caregivers to assist with daily activities and provide emotional support. There is a high prevalence of embarrassment among individuals with ET, which may be a result of the outwardly visible nature of tremor.
