Motor perseveration is an early sign of Parkinson's disease.

چکیده
Perseveration in the generation of random motor behavior was examined by means of the Vienna perseverance task in groups of de novo (n = 18) and treated (n = 18) patients with early PD, and in control subjects (n = 18). In comparison with control subjects, both the de novo and treated patients with PD were relatively unable to generate random motor sequences, indicating a decreased ability to switch cortical behavioral programs in PD. An impairment of random motor generation appears to be a very early feature of PD.

Elementary motor perseveration in early diagnosis of progressive supranuclear palsy.
Three patients with progressive supranuclear palsy (PSP) with different symptoms at onset presented intense elementary motor perseveration before the appearance of the distinctive features of the illness. In elementary motor perseveration once an element of a movement has begun it is no longer inhibited at the right time and continues unchecked. Perseverations were observed in these patients du...
متن کاملStrength-endurance training with olive oil consumption on motor performance and oxidative stress level in the brain of male parkinsonian rats.
Introduction: Parkinson's disease is a chronic brain disorder that occurs as a result of the loss, reduction or damage of dopamine-producing nerve cells in the substantia nigra located in the midbrain. The purpose of this study is to determine the effect of 8 weeks of strength-endurance training with olive oil consumption on motor performance and oxidative stress level in the brain of male park...
متن کاملQuantitative Electromyographic Analysis of Reaction Time to External Auditory Stimuli in Drug-Naïve Parkinson's Disease
Evaluation of motor symptoms in Parkinson's disease (PD) is still based on clinical rating scales by clinicians. Reaction time (RT) is the time interval between a specific stimulus and the start of muscle response. The aim of this study was to identify the characteristics of RT responses in PD patients using electromyography (EMG) and to elucidate the relationship between RT and clinical featur...

Objective: Previous studies showed that grape seed extract (GSE) is an excellent natural substance with potent antioxidant effect and free radical scavenger. This study aimed to evaluate the effect of GSE on motor dysfunctions and thalamic local Electroencephalography (EEG) frequency bands' powers in rats with Parkinson's disease (PD). Materials and Methods: In this study 8 µg 6-hydroxydopamin...
متن کاملMotor perseveration in geriatric medical patients.
Perseveration has long been considered as a pathognomonic sign of neurological disease, yet, surprisingly, little research exists regarding the accuracy of this assumption. This study matched 56 geriatric medical inpatients with 56 inpatients with recent cerebrovascular accidents. Participants were given one of two measures of general cognition and four Lurian tasks of motor coordination. The r...
