Differential Diagnosis for Tremors
Single most likely diagnosis
- Essential Tremor: This is the most common cause of tremors, characterized by a bilateral, symmetric tremor that typically affects the hands, but can also involve the head, voice, or other body parts. It is often familial and can be exacerbated by stress, fatigue, or certain medications.
Other Likely diagnoses
- Parkinson's Disease: While Parkinson's disease is often associated with other symptoms such as bradykinesia, rigidity, and postural instability, tremors can be a prominent feature, especially in the early stages. The tremor is typically unilateral and asymmetric.
- Anxiety or Stress-related Tremor: Tremors can be a manifestation of anxiety or stress, often accompanied by other symptoms such as palpitations, sweating, and tremulousness.
- Medication-induced Tremor: Certain medications, such as beta-agonists, anticholinergics, and certain antidepressants, can cause tremors as a side effect.
- Hyperthyroidism: An overactive thyroid gland can cause tremors, among other symptoms such as weight loss, palpitations, and heat intolerance.
Do Not Miss (ddxs that may not be likely, but would be deadly if missed.)
- Pheochromocytoma: A rare tumor of the adrenal gland that can cause episodic tremors, hypertension, and other symptoms. If missed, it can lead to life-threatening complications.
- Thyroid Storm: A life-threatening complication of untreated or undertreated hyperthyroidism, characterized by severe tremors, fever, and cardiovascular instability.
- Wilson's Disease: A rare genetic disorder that can cause tremors, among other symptoms such as liver disease and psychiatric disturbances. If left untreated, it can lead to severe disability and death.
Rare diagnoses
- Dystonic Tremor: A rare condition characterized by tremors and dystonic posturing, often associated with other movement disorders.
- Orthostatic Tremor: A rare condition characterized by tremors that occur when standing, often accompanied by other symptoms such as dizziness and unsteadiness.
- Neurodegenerative disorders: Such as multiple system atrophy, progressive supranuclear palsy, and corticobasal degeneration, which can cause tremors among other symptoms.
