Essential Tremor (ET) is a widespread neurological condition that is characterised by involuntary shaking that primarily affects the hands but it also extends to also impact visual stability. These tremors pass often unnoticed in their subtler forms, and they become recognisable as ET only when they manifest prominently. ET presents distinct challenges in motor control and visual coordination, especially in older individuals but note however that it should not be confused with Parkinson’s disease. Whilst the precise cause of ET remains elusive, there is a growing research that indicates a significant role played by the inferior olive (IO) and more specifically its rhythmic neural activity. As an integral part of the cerebellar system, this IO’s rhythmic neural activity that ultimately coordinates the cerebellar motor signals that drive motor coordination is relevant to understanding the ET is suggested as a potential driver for ET.
