Clinical and Imaging Study of Isolated and Mixed Rest and Action Tremor-Essential Tremor versus Parkinson's Disease.

Background: Some patients present an unusual association of both action tremor (AT) and rest tremor (RT) making the differential diagnosis between essential tremor (ET) and Parkinson's disease (PD) difficult.

Aim: To investigate this particular clinical picture trying to focus on possible peculiar clinical inferences.

Patients And Methods: Twenty-three patients with atypical tremor syndrome were selected for the study.

The relationship between cerebral vascular disease and parkinsonism: The VADO study.

Background: The observation of gait abnormalities, parkinsonism and vascular lesions in elderly patients is often reported as vascular parkinsonism (VP). However the status of striatal dopamine transporter (DAT) and the effects of brain vascular lesions on motor features and levodopa responsiveness are poorly defined.

Methods: We recorded clinical features, chronic response to levodopa and vascular risk factors in a cross-sectional cohort of consecutive elderly patients with possible Parkinson's disease (PD) or VP recruited in 20 centers in Italy.

Acute Akinesia, an unusual complication in Parkinson's Disease: a case report.

Acute akinesia (AA) is a rare but serious complication of Parkinson's Disease (PD) 0,3% of all patients with PD). It can be related to infectious condition, surgery, or treatment changes. AA can completely recover or result in some motor deficits, and, in the most severe forms, it may lead to untreatable complications and death.

How many parkinsonian patients are suitable candidates for deep brain stimulation of subthalamic nucleus? Results of a questionnaire.

We used a CAPSIT-based questionnaire to estimate the percentage of parkinsonian patients suitable for subthalamic nucleus (STN) deep brain stimulation (DBS) in a movement disorders clinic. We found that out of 641 consecutive PD patients only 1.6% fulfilled strict STN-DBS criteria.
