Essential tremor (ET) is the most common tremor disorder in adults. In addition to upper limbs, the tremor in ET may also involve head, jaw, voice, tongue, and trunk. Though head tremor (HT) is commonly present in patients with ET, large comparative studies of ET patients with HT (HT+) and without HT (HT-) are few. To determine whether ET with HT i...

Background and purpose: Impairment of cognitive functions occurs in essential tremor, though the mechanism is largely unknown. The aim of this study was to find microstructural correlates of cognitive dysfunction seen in essential tremor by using DTI and neuropsychological assessment. Materials and methods: Fifty-five patients with essential tre...

Background and purpose: Impairment of cognitive functions occurs in essential tremor (ET) although the mechanism is largely unknown. A possible association between cognitive performance and brain atrophy in ET patients was examined using neuropsychological tests and voxel-based morphometry (VBM). Methods: Twenty-five patients with ET and 25 matc...

Essential tremor (ET) is one of the most common neurological diseases; but aetio-pathogenesis of ET is largely unknown. Major advances in neuroimaging may help us understand the mechanisms and networks involved in ET. Most commonly employed techniques include functional and structural neuroimaging. Functional imaging studies suggest that tremors in...

Background: Restless Legs Syndrome (RLS) is associated with impaired central dopaminergic neurotransmission. Though a link between RLS and parkinsonism has been proposed, the prevalence of RLS in parkinsonian disorders is poorly documented. Objective: To determine the prevalence of RLS in patients with Parkinson's Disease (PD), Progressive Supra...
