Essential tremor and ageing

Essential Tremor (ET) is a very common neurological condition that increases with age. Tremor progresses in severity and body distribution with aging. Patients with ET may develop clinical signs of cerebellar dysfunction. Other neurological signs may be seen as well, but their association with ET has not been fully solidified. Pathological changes in the cerebellum are seen with ET, although describing ET as a neurodegenerative disease is still premature. Links to other neurodegenerative disorders such as Alzheimer’s and Parkinson’s disease can be seen but may simply reflect co-incidental co-morbidities of aging.
