Abstract

Background:

Research studies have shown an association between essential tremor (ET) and dementia, although dementia in ET is not often regarded as a clinically important issue.

Phenomenology Shown:

We present three tangible visual records of patients with ET who have developed concurrent, comorbid dementia.

Educational Value:

ET is a risk factor for dementia. This non-motor feature of the disease has substantial effects on the lives of patients and their families.

KEYWORDS:

Clinical Dementia Rating; Essential tremor; cognitive decline; dementia
