DaTSCAN is indicated in cases of tremor when its origin is uncertain. Although this method can distinguish essential tremor from Parkinson's syndrome, it is unable to distinguish between Parkinson's disease , Dementia with Lewy bodies , Parkinson's disease dementia , [ 3 ] multiple system atrophy or progressive supranuclear palsy .
Ulixacaltamide is an investigational new drug developed by Praxis Precision Medicines, designed to treat essential tremor, [1] a common neurological disorder characterized by involuntary rhythmic shaking.

Essential tremor (sometimes inaccurately called benign essential tremor) is the most common of the more than 20 types of tremor. Although the tremor may be mild and nonprogressive in some people, in others, the tremor is slowly progressive, starting on one side of the body but affecting both sides within 3 years.

Depending on the location of cerebellar ...

For non-Parkinsonian essential tremor, the lead is placed in either the ventrointermediate nucleus of the thalamus or the zona incerta; [13] for dystonia and symptoms associated with PD (rigidity, bradykinesia/akinesia, and tremor), the lead may be placed in either the globus pallidus internus or the subthalamic nucleus; for OCD and depression ...
Primidone is not indicated for essential tremor but is often used as a first-line therapy for essential tremor, as is propranolol. In tremor amplitude reduction, it is just as effective as propranolol, reducing it by 50%. Both drugs are well studied for this condition, unlike other therapies, and are recommended for initial treatment.
