Pathophysiology of nonparkinsonian tremors.

Patients with nonparkinsonian tremors are the second largest group treated with functional neurosurgery. We summarize the present pathophysiological knowledge of these conditions. Essential tremor (ET) may be due to oscillations within the olivocerebellar circuit. There is experimental evidence from animal models for such a mechanism, and clinical data indicate an abnormal function of the cereb...

Concurrent Parkinson tremors.

1. Concurrent resting and postural tremors of patients with idiopathic Parkinson's disease were monitored using transducers responding to angular velocity of rotation. Spectra and correlation functions were calculated for each pair of records. 2. When concurrent tremor spectra share indistinguishable fundamental frequencies, have statistically significant peaks in their coherence spectra at tho...

The Diagnostic Significance of Tremors

or abolished during movement. This is absent during sleep and often during complete muscular relaxation, as when resting in bed. When fully developed this tremor may be widespread and include several components. 2. Intention, action. or motor tremor. This type of tremor is absent as a rule when the patient is at rest and appears only during movements, especially those which require exact co-ord...

Essential tremors mimicking as dysgraphia.

A 13 years male was referred to the Learning Disability Clinic with the complaint of illegible handwriting, dropping academic grades with a possibility of dysgraphia. The handwriting fluency and legibility deteriorated in time controlled situations such as examinations. He was slow in copying but had no issues with concentration, retrieval and had a good memory. Family history of tremors in fat...
