Background: Multiple Sclerosis (MS) is a demyelinating disorder of the central nervous system. Tremors are a common problem in the patients suffering from MS which is mostly observed in the arms but can also affect the other body parts. There have been few studies on tremors among the MS patients.  Objectives: This study is the first to report the prevalence of tremor in a group of MS pat...

Specific behavioral patterns are expressed by complex combinations of muscle coordination. Tremors are simple behavioral patterns and are the focus of studies investigating motor coordination mechanisms in the brain. T-type Ca(2+) channels mediate intrinsic neuronal oscillations and rhythmic burst spiking, and facilitate the generation of tremor rhythms in motor circuits. Despite substantial ev...

Background: Tremor which is the most common abnormal movement in the neonatal period might be a benign condition or the result of pathologic events and is divided into two subtypes, namely fine tremor and coarse tremor. Fine tremor is usually benign and results from some metabolic disturbance, such as hypoglycemia. On the other hand, coarse tremor is an indicator of brain insult and should be r...

normal 0 false false false en-us x-none ar-sa background: t he study on transcranial sonocraphy (tcs) as a diagnostic test for parkinson’s disease (pd) has been neglected in some hospitals. the current study was conducted as the first study to investigate the utility of tcs for diagnosis of pd and its ability to distinguish pd from essential tremor (et) in an iranian population. materials and m...

Objective(s): Due to unsatisfactory response or intolerable side effects of current drugs, treatment of essential tremor remains inadequate. Thus, we aimed to investigate the protective and therapeutic effects of aqueous and ethanolic extracts of Crocus sativus (saffron), and its active consistent, safranal, on the harmaline-induced tremor in mice. Materials and Methods: To induce tremor, harma...

INTRODUCTION Foveation is the fundamental requirement for clear vision. Saccades rapidly shift the gaze to the interesting target while gaze holding ensures foveation of the desired object. PURPOSE We will review the pertinent physiology of saccades and gaze holding and their pathophysiology leading to saccadic oscillations, slow saccades, saccadic dysmetria, and nystagmus. SUMMARY Motor co...

The phenomenological classification of tremor is determined by finding out: c which parts of the patient’s body are affected by tremor? c what types (or components) of tremor, classified by state of activity, are present at those anatomical sites? The following definitions are used to describe the various tremor components evident on examination: c Rest tremor is a tremor present in a body part...

purpose: transcranial magnetic resonance guided focused ultrasound (mrgfus) is a new development in the field of functional neurosurgery. a comprehensive review of the current literature was performed to evaluate of transcranial mrgfus in treatment of essential tremor (et) and parkinson’s disease. methods: articles available in electronic databases of pubmed, and web of science, as of july 2016...

BACKGROUND Dystonia and tremor share many commonalities. Isolated tremor is part of the phenomenological spectrum of isolated dystonia and of essential tremor. The occurrence of subtle features of dystonia may allow one to differentiate dystonic tremor from essential tremor. Diagnostic uncertainty is enhanced when no features of dystonia are found in patients with a tremor syndrome, raising the...
