There are a number of ways in which tremor can be diagnosed.
The diagnosis will typically begin with the person’s medical history being taken.
The physician will be looking not only for offending drugs (drugs prescribed for other medical conditions which can cause tremor as a side effect), but for signs and symptoms that may have previously been noted but for which no action has been taken. The physician will also ask about the family history.
While the diagnosis of essential tremor remains a visual one, Brain scans Magnetic Resonance Imaging (MRI) and Computerised Tomography (CT) may be helpful in eliminating any other conditions which also produce tremor as a symptom.
Blood samples may also be taken to rule out thyroid or copper metabolism problems.
DATScan a diagnostic test can distinguish between essential tremor and tremors of Parkinson's disease.
