Intention Tremor Diagnosis and Management

Clinical Assessment and Diagnosis

The American College of Radiology recommends assessing for associated cerebellar signs, such as gait instability, dysarthria, truncal ataxia, and coordination difficulties, in patients with intention tremor 1
The American College of Radiology suggests looking for parkinsonian features, such as fine tremor unaffected by intention, rigidity, staccato speech, and shuffling gait, to differentiate intention tremor from other diagnoses 1
The American College of Radiology advises assessing for asterixis, a flapping tremor that indicates hepatic encephalopathy rather than cerebellar pathology 1

The American College of Radiology recommends MRI brain without and with IV contrast as the first-line imaging study for evaluating intention tremor to identify cerebellar lesions, demyelinating disease, stroke, or structural abnormalities 2, 3
High-resolution T2-weighted sequences provide excellent visualization of cerebellar structures and can detect subtle lesions, according to the American College of Radiology 2, 3
The American College of Radiology suggests that contrast administration facilitates detection of inflammatory changes, demyelinating plaques, and neoplasms 2

The American College of Radiology recommends thyroid function tests to assess for thyrotoxicosis, which can cause tremor through increased sympathetic activity 4
The American College of Radiology suggests assessing for hyperparathyroidism, particularly in patients with uremia, through metabolic panel testing 4
The American College of Radiology advises ruling out hepatic encephalopathy if asterixis is present, through liver function tests 1
The Journal of the American College of Radiology recommends checking vitamin B12 and folate levels, as nutritional deficiencies can cause cerebellar dysfunction 5

The Journal of the American College of Radiology suggests considering cerebrospinal fluid analysis if inflammatory or infectious etiology is suspected, particularly for rapidly progressive symptoms 5
The European Heart Journal recommends urgent evaluation for rapidly progressive symptoms, which may suggest prion disease, inflammatory conditions, or neoplastic processes 5
The European Heart Journal advises immediate imaging for focal neurological deficits, which may indicate a structural lesion 8
The Journal of the American College of Radiology recommends assessing functional impact, including effects on activities of daily living, to guide treatment decisions 9, 6
