Differential Diagnosis for Intermittent Inner Tremors Unilateral with Negative MRI and EEG in 59 yo Woman
- Single most likely diagnosis
- Essential Tremor: This is a common movement disorder that can cause unilateral tremors, and the absence of abnormalities on MRI and EEG does not rule out this diagnosis. The age of the patient and the intermittent nature of the tremors also support this diagnosis.
- Other Likely diagnoses
- Anxiety or Stress-Related Tremors: Inner tremors can be a symptom of anxiety or stress, and this diagnosis should be considered, especially if the patient has a history of anxiety or stress.
- Orthostatic Tremor: This is a rare condition, but it can cause unilateral tremors, and the diagnosis can be made based on clinical presentation and response to treatment.
- Dystonic Tremor: This is a type of tremor that can occur in patients with dystonia, and it can be unilateral.
- Do Not Miss (ddxs that may not be likely, but would be deadly if missed.)
- Multiple Sclerosis: Although the MRI is negative, multiple sclerosis can cause tremors, and a negative MRI does not completely rule out this diagnosis. Further evaluation, such as a spinal tap or evoked potentials, may be necessary.
- Stroke or Transient Ischemic Attack: A stroke or TIA can cause unilateral tremors, and it is essential to evaluate the patient for any signs of cerebrovascular disease.
- Wilson's Disease: This is a rare genetic disorder that can cause tremors, and it is essential to consider this diagnosis, especially if the patient has a family history of the disease.
- Rare diagnoses
- Neuropathic Tremor: This is a rare condition that can cause unilateral tremors due to nerve damage.
- Spinocerebellar Ataxia: This is a group of rare genetic disorders that can cause tremors, ataxia, and other neurological symptoms.
- Whipple's Disease: This is a rare infectious disease that can cause tremors, and it is essential to consider this diagnosis if the patient has a history of travel or exposure to contaminated food or water.
