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.
