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 [Disease name] from other Diseases
[Disease name] must be differentiated from other diseases that cause [clinical feature 1], [clinical feature 2], and [clinical feature 3], such as [differential dx1], [differential dx2], and [differential dx3].
OR
[Disease name] must be differentiated from [differential dx1], [differential dx2], and [differential dx3].
OR
As [disease name] manifests in a variety of clinical forms, differentiation must be established in accordance with the particular subtype. [Subtype name 1] must be differentiated from other diseases that cause [clinical feature 1], such as [differential dx1] and [differential dx2]. In contrast, [subtype name 2] must be differentiated from other diseases that cause [clinical feature 2], such as [differential dx3] and [differential dx4].
Differentiating [disease name] from other diseases on the basis of [symptom 1], [symptom 2], and [symptom 3]
On the basis [symptom 1], [symptom 2], and [symptom 3], [disease name] must be differentiated from [disease 1], [disease 2], [disease 3], [disease 4], [disease 5], and [disease 6][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 |
| Parkinson’s disease | Resting Tremor - Unilateral onset | Slow movement, stooped posture, difficulty walking, rigidity imbalance, depression, apathy |
| Physiologic Tremor | Postural tremor - High frequency, low amplitude | |
| 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. |
| Alcoholism | Action - Postural Tremor | Less movement (hypokinesis), increased muscle tone |
| Hyperthyroidism | Action - Postural Tremor | Mixed presentation |
