Overview
Tremor must be differentiated from other diseases that cause myoclonus, clonus, asterixis, and epilepsia partialis continua.
OR
[Disease name] must be differentiated from [[differential dx1], [differential dx2], and [differential dx3].
Differentiating Tremor from other Diseases
- Differentiating the cause of tremor from other diseases on the basis of the type of tremor, associated signs, and symptoms.[1].
| Common Cause of Tremor | Differentiating Feature of Tremor | Main Feature of Disease |
| Essential tremor | Postural Tremor - [Frequency]] 4–12 Hz, Bilateral onset | gait ataxia, vestibulocerebellar involvement, reduced by alcohol, family history, stress/fatigue can increase tremor amplitude, increases with voluntary movements |
| Parkinson’s disease | Resting Tremor - Unilateral onset | Bradykinesia, micrographia, stooped posture, ataxia, rigidity, imbalance, depression, apathy, decreases with voluntary movements |
| Physiologic Tremor | Postural tremor - High frequency, low amplitude | Enahanced with drug and toxins, no neurological feature |
| Cerebellar Tremor | Intention tremor - Low frequency <4 Hz | Occurs in multiple sclerosis, stroke, brainstem tumor, or cerebellar trauma. May feature ataxia, dysmetria, dysdiadochokinesia, and dysarthria. |
| Drug Induced Tremor | Can enhance rest, action, postural tremors | Amiodarone, bronchodilators, lithium, metoclopramide, neuroleptics, theophylline, valproate |
| Orthostatic Tremor | Essential tremor variant, high frequency 14 Hz-18 Hz | Occurs in the legs on standing and is relieved by sitting down |
